Abstract

While the leaf insects (Phylliidae) are a well-supported group within Phasmatodea, the genus Phyllium Illiger, 1798 has repeatedly been recovered as paraphyletic. Here, the Phyllium (Phyllium) celebicum species group is reviewed and its distinctiveness from the remaining Phylliini genera and subgenera in a phylogenetic context based on morphological review and a phylogenetic analysis of three genes (nuclear gene 28S and mitochondrial genes COI and 16S) from most known and multiple undescribed species is shown. A new genus, Cryptophyllium gen. nov., is erected to partially accommodate the former members of the celebicum species group. Two species, Phyllium ericoriai Hennemann et al., 2009 and Phyllium bonifacioi Lit & Eusebio, 2014 morphologically and molecularly do not fall within this clade and are therefore left within Phyllium (Phyllium). The transfer of the remaining celebicum group members from Phyllium Illiger, 1798 to this new genus creates the following new combinations; Cryptophyllium athanysus (Westwood, 1859), comb. nov.; Cryptophyllium celebicum (de Haan, 1842), comb. nov.; Cryptophyllium chrisangi (Seow-Choen, 2017), comb. nov.; Cryptophyllium drunganum (Yang, 1995), comb. nov.; Cryptophyllium oyae (Cumming & Le Tirant, 2020), comb. nov.; Cryptophyllium parum (Liu, 1993), comb. nov.; Cryptophyllium rarum (Liu, 1993), comb. nov.; Cryptophyllium tibetense (Liu, 1993), comb. nov.; Cryptophyllium westwoodii (Wood-Mason, 1875), comb. nov.; Cryptophyllium yapicum (Cumming & Teemsma, 2018), comb. nov.; and Cryptophyllium yunnanense (Liu, 1993), comb. nov.

The review of specimens belonging to this clade also revealed 13 undescribed species, which are described within as: Cryptophyllium animatum gen. et sp. nov. from Vietnam: Quang Nam Province; Cryptophyllium bankoi gen. et sp. nov. from Vietnam: Quang Ngai, Thua Thien Hue, Da Nang, Gia Lai, Quang Nam, and Dak Nong Provinces;Cryptophyllium bollensi gen. et sp. nov. from Vietnam: Ninh Thuan Province; Cryptophyllium daparo gen. et sp. nov. from China: Yunnan Province; Cryptophyllium echidna gen. et sp. nov. from Indonesia: Wangi-wangi Island; Cryptophyllium faulkneri gen. et sp. nov. from Vietnam: Quang Ngai and Lam Dong Provinces; Cryptophyllium icarus gen. et sp. nov. from Vietnam: Lam Dong and Dak Lak Provinces; Cryptophyllium khmer gen. et sp. nov. from Cambodia: Koh Kong and Siem Reap Provinces; Cryptophyllium limogesi gen. et sp. nov. from Vietnam: Lam Dong, Dak Lak, and Dak Nong Provinces; Cryptophyllium liyananae gen. et sp. nov. from China: Guangxi Province; Cryptophyllium nuichuaense gen. et sp. nov. from Vietnam: Ninh Thuan Province;Cryptophyllium phami gen. et sp. nov. from Vietnam: Dong Nai and Ninh Thuan Provinces; and Cryptophyllium wennae gen. et sp. nov. from China: Yunnan Province. All newly described species are morphologically described, illustrated, and molecularly compared to congenerics.

With the molecular results revealing cryptic taxa, it was found necessary for Cryptophyllium westwoodii (Wood-Mason, 1875), comb. nov. to have a neotype specimen designated to allow accurate differentiation from congenerics. To conclude, male and female dichotomous keys to species for the Cryptophyllium gen. nov. are presented.

Abstract

This report describes Thismia belumensis Siti-Munirah & Suhaimi-Miloko, a novel species of achlorophyllous herb discovered in the Royal Belum State Park, Peninsular Malaysia. This new species is unlike any previously described species of Thismia. In particular, T. belumensis possesses a unique annulus, which has been expanded and modified into a cucullate (hood-like) structure. This structure covers the apical floral tube and has an opening on one side facing a thickened part of the annulus, and the off-centre floral aperture confers a zygomorphic symmetry to the flower, indicating T. belumensis is more similar to Thismia labiata J.J.Sm. This morphological detail makes this new species distinct from all other described species of Thismia. In this report, we provide descriptions, illustrations, colour plates, and the provisional conservation status of Thismia belumensis.

Thismia belumensis Siti-Munirah & Suhaimi-Miloko, sp. nov.

Diagnosis: Most similar to Thismia labiata J.J.Sm. but differing in the floral tube partially covered by a massively expanded cucullate bilabiate annulus, longer outer tepals appendage, obovate to spathulate rather than linear to filiform inner tepals and the supraconnective apex curved outwards like a skirt rather than straight.

Distribution: Endemic to Perak, Peninsular Malaysia. Currently known only from the type locality (Map 1).

Ecology: Lowland dipterocarp forest, under shade, 260–290 m altitude. Flowering from June to October. Thismia belumensis was found growing within tree leaf litter and between the buttress roots of large trees (Fig. 4). Two other Thismia species were also discovered within a radius of about 350 meters, T. javanica and Thismia sp. 1 (see Fig. 5), which is currently suspected by the authors to be Thismia arachnites Ridl., but further examination is still needed. All plants were found close to the walking trail.

Etymology: The species is named after The Royal Belum State Park, the type locality of this species.

Abstract

The outstanding biodiversity of the Guiana Shield has raised many questions about its origins and evolution. Frogs of the genera Adelastes, Otophryne and Synapturanus form an ancient lineage distributed mostly across this region. These genera display strikingly disparate morphologies and life-history traits. Notably, Synapturanus is conspicuously adapted to fossoriality and is the only genus within this group to have dispersed further into Amazonia. Moreover, morphological differences among Synapturanus species suggest different degrees of fossoriality that might be linked to their biogeographical history. Through integrative analysis of genetic, morphometric and acoustic data, we delimited 25 species in this clade, representing a fourfold increase. We found that the entire clade started to diversify ~55 Mya and Synapturanus ~30 Mya. Members of this genus probably dispersed three times out of the Guiana Shield both before and after the Pebas system, a wetland ecosystem occupying most of Western Amazonia during the Miocene. Using a three-dimensional osteological dataset, we characterized a high morphological disparity across the three genera. Within Synapturanus, we further characterized distinct phenotypes that emerged concomitantly with dispersals during the Miocene and possibly represent adaptations to different habitats, such as soils with different physical properties.

A new Tedania species (Porifera) was collect using remotely operated vehicles during the Canadian mission HUD2010-029 and the British RRS Discovery Cruise DY081, on the Orphan Seamount near the Orphan Knoll, northwest Atlantic, between 2999.88 and 3450.4 m depth. Orphan Knoll is an isolated, drowned continental fragment 550 km northeast Newfoundland in the Labrador Sea. This region is biologically rich and complex and in 2007, the regional fisheries management organization operating in the area regulated that no vessel shall engage in bottom-contact fishing activities until reviewed in 2020 with a review slated at the end of this year. Members of the genus Tedania are uncommon in the temperate northern hemisphere with only six species known previously: Tedania (Tedania) anhelans; Tedania (Tedania) pilarriosae; Tedania (Tedania) suctoria; Tedania (Tedania) urgorrii; Tedania (Tedaniopsis) gurjanovae; and Tedania (Tedaniopsis) phacellina. The particular features of the new sponge we describe are the very peculiar external morphology which is tree-like with dichotomous branching—a morphology not previously described in this subgenus; and the combination of spicules found: long styles, the typical tornotes of the subgenus and two sizes of onychaetes. Additional information is provided on other species of Tedaniopsis described from the Atlantic Ocean. Based on the characteristics reported, we propose a new species, Tedania (Tedaniopsis) rappi sp. nov. in honor of Prof. Hans Tore Rapp (1972–2020), University of Bergen, Norway, a renowned sponge taxonomist and coordinator of the Horizon 2020 SponGES project. The holotype of T. (T.) phacellina Topsent, 1912 from the Azores, the only other northern Atlantic species in the subgenus Tedaniopsis, was reviewed for comparison.

Abstract

A new species of the genus Dictyanthus is herein described and illustrated, more than 30 years since the last paper describing new species of this genus. Dictyanthus stevensii sp. nov. is known only from the Zoque forest in the Chimalapas region in the state of Oaxaca, Mexico. This species differs from all other species because it has the smallest flowers within the genus. It is morphologically related to D. eximius, a microendemic species of Chiapas. Information on the distribution and habitat of this new species is given, and its conservation status is proposed as Critically Endangered B2ab(ii). An identification key to Dictyanthus species in southern and southerneast Mexico is also provided.

Dictyanthus stevensii Gonz.-Martínez, Lozada-Pérez et L.O. Alvarado sp. nov.

Dictyanthus stevensii is morphologically related to D. eximius (Stevens 1988: 1552) Stevens (2000: 243) but differs by having a row of uncinated and interpetiolar trichomes, the indumentum of young stems consists of uncinated and straight trichomes only, corolla green with undulate margin, the lobes of the corona are oblong with spatulate, rounded apex or slightly bilobulated, the apex is exerted from the corolla tube and with the anthers vertices slightly exerted.

Etymology:— The specific epithet honors Dr. Warren Douglas Stevens (b. 1944), botanist, collector and investigator at the Missouri Botanical Garden. Stevens has greatly contributed to the knowledge and taxonomy of the subfamily Asclepiadoidae. Among his contributions, his participation as editor in chief of the Flora of Nicaragua is one of the most important. He has also described over 130 new species from many genera of Asclepiadoideae and other families, mostly from Mexico and Central America. He carried out the most exhaustive taxonomic revision of Dictyanthus (Stevens 1975, 1988) and recognized it as an independent genus from Matalea s.l., based on morphological evidence (Stevens 1999, 2000). In addition, he described six new species for the genus and provided new information about this genus in the Mexican Flora (Stevens 1988).

Abstract

Blind snakes (Typhlopidae) are an enigmatic group of small burrowing snakes whose anatomy, phylogenetics, and biodiversity remain poorly known. Madatyphlops comorensis (Boulenger, 1889), endemic to the Comoros Archipelago in the Western Indian Ocean, is one of many species whose phylogenetic placement and generic assignment is unclear. We used DNA barcoding, external morphological examination, and osteological data from 3D reconstruction with micro‐CT to study specimens of Madatyphlops from the Comoros Archipelago. Our results support the placement of M. comorensis in Madatyphlops and the recognition of the specimens from Mayotte Island as a closely related but distinct species, which we describe as Madatyphlops eudelini sp. nov. In this context, we present the first detailed osteological descriptions of any species of Madatyphlops, which we hope will serve as groundwork for further osteological studies in this genus and contribute to our limited but growing understanding of the osteology of typhlopid snakes.

Caridina thachlam

Do, Cao & von Rintelen, 2021

DOI: 10.11646/zootaxa.4933.3.8

Abstract

The first stygobitic species of atyid freshwater shrimps from Vietnam is described from Cuc Phuong National Park, Northern Vietnam. Caridina thachlam sp. nov. can be distinguished from its congeners by a suite of morphological characters such as strongly reduced eyes without eyestalk, short and almost unarmed rostrum and slender pereiopods. Molecular phylogenetic data from the mitochondrial cytochrome oxidase subunit I (COI) and 16S ribosomal RNA genes also support the distinctiveness of the new species from all other species that we have examined.

In terms of species-level diversity, the genus Crassula Linnaeus (1753: 282) is by far the most diverse in the Crassulaceae within the Flora of Southern Africa region [Namibia, Botswana, Eswatini (formerly Swaziland), Lesotho, South Africa] (Tölken 1977a, b, 1985). In this region diversity is highest in the Fynbos and Succulent Karoo Biomes, both of which straddle the southern Cape, an area represented in the Western and Eastern Cape provinces.

Abstract

Aeschynanthus rejieaefrom Panglima Sugala, one of the few remaining forested areas in Tawi-Tawi, Philippines, is illustrated and described as a new species. It resembles A. obconicus and A. ovatus by the ovate leaves and dense indumentum in the external calyx and corolla. However, A. rejieae is distinguished by having leaves that have persistent sparse pubescence, campanulate calyx with dense hirsute indumentum both internally and externally, and ovary with a glandular cilia. This species is named after Rejie Sahali-Generale, who initiated the biodiversity conservation in Panglima Sugala. This new discovery further highlights the urgent need to study and conserve the remaining forests of Tawi-Tawi.

Abstract

The Opiliones superfamily Triaenonychoidea currently includes two families, the monogeneric New Zealand–endemic Synthetonychiidae Forster, 1954 and Triaenonychidae Sørensen, 1886, a diverse family distributed mostly throughout the temperate Gondwanan terranes, with ~110 genera and ~500 species and subspecies currently described. Traditionally, Triaenonychidae has been divided into subfamilies diagnosed by very few morphological characters largely derived from the troublesome ‘Roewerian system’ of morphology, and classifications based on this system led to many complications. Recent research within Triaenonychoidea using morphology and traditional multilocus data has shown multiple deeply divergent lineages, non-monophyly of Triaenonychidae, and non-monophyly of subfamilies, necessitating a revision based on phylogenomic data. We used sequence capture of ultraconserved elements across 164 samples to create a 50% taxon occupancy matrix with 704 loci. Using phylogenomic and morphological examinations, we explored family-level relationships within Triaenonychoidea, including describing two new families: (1) Lomanellidae Mendes & Derkarabetian, fam. nov., consisting of Lomanella Pocock, 1903, and a newly described genus Abaddon Derkarabetian & Baker, gen. nov. with one species, A. despoliator Derkarabetian, sp. nov.; and (2) the elevation to family of Buemarinoidae Karaman, 2019, consisting of Buemarinoa Roewer, 1956, Fumontana Shear, 1977, Flavonuncia Lawrence, 1959, and a newly described genus Turonychus Derkarabetian, Prieto & Giribet, gen. nov., with one species, T. fadriquei Derkarabetian, Prieto & Giribet, sp. nov. With our dataset we also explored phylogenomic relationships within Triaenonychidae with an extensive taxon set including samples representing ~80% of the genus-level diversity. Based on our results we (1) discuss systematics of this family including the historical use of subfamilies, (2) reassess morphology in the context of our phylogeny, (3) hypothesise placement for all unsampled genera, (4) highlight lineages most in need of taxonomic revision, and (5) provide an updated species-level checklist. Aside from describing new taxa, our study provides the phylogenomic context necessary for future evolutionary and systematic research across this diverse lineage.

Gasteruption jaculator (Linnaeus, 1758)

in Bogusch, 2021.

DOI: 10.11646/zootaxa.4935.1.1

Abstract

The genus Gasteruption (Gasteruptiidae) is represented in Europe by more than 30 species. Of these, twenty-one are recorded from the Czech Republic and Slovakia, with six being new records for the Czech Republic and eight for Slovakia. Three species are recorded as new for Bohemia (western part of the Czech Republic). Gasteruption goberti is excluded from the fauna of the Czech Republic because specimens previously identified as G. goberti belong to G. caucasicum. Four species (G. assectator, G. caucasicum, G. jaculator and G. nigritarse) are common and widespread in both countries, G. tournieri is very common but prefers warmer regions. Only G, subtile occurs predominantly in higher altitudes of mountain ranges, while the other species are usually restricted to or are more common in warmer regions. Gasteruption opacum and G. subtile are regionally extinct from the Czech Republic and G. paternum from Slovakia, with the the most recent records of these species are pre-1990. Gasteruption freyi, G. hastator and G. hungaricum are considered very endangered thermophilous species of loess walls and steppe habitats with a marked loss of occurrence records post-1990. Locally common but much rarer than in the past are G. erythrostomum and G. boreale. Due to the fact that recent determination keys are focused on other regions, a determination key for all species recorded in central Europe is presented.

Abstract

There are 29 species or subspecies in genus Hexacentrus occurring in Asia, Africa and Australia. Because of its similar appearance, it is not easy to distinguish them by traditional methods. In this study, we collected samples and sequenced COI genes from wide range. By reconstructing the gene tree, we found one new species, Hexacentrus formosanus Chen et He sp. nov., from Taiwan. The new species is similar to H. expansus or H. inflatissimus, but differs from the former in male Cu2 vein of left tegmina curved and slender, and spectrum of male left tegmina slender and subsquare; differs from the later by body size smaller and female tegmina narrow and short. The type specimens are deposited in National Museum of Natural Science, Taichung, Taiwan (NMNS). H. japonicus hareyamai is treated as species level, H. hareyamai stat. nov.

Dzharatitanis kingi

Averianov & Sues, 2021

DOI: 10.1371/journal.pone.0246620

twitter.com/AndreyAtuchin

Abstract

Dzharatitanis kingi gen. et sp. nov. is based on an isolated anterior caudal vertebra (USNM 538127) from the Upper Cretaceous (Turonian) Bissekty Formation at Dzharakuduk, Uzbekistan. Phylogenetic analysis places the new taxon within the diplodocoid clade Rebbachisauridae. This is the first rebbachisaurid reported from Asia and one of the youngest rebbachisaurids in the known fossil record. The caudal is characterized by a slightly opisthocoelous centrum, ‘wing-like’ transverse processes with large but shallow PRCDF and POCDF, and the absence of a hyposphenal ridge and of TPRL and TPOL. The neural spine has high SPRL, SPDL, SPOL, and POSL and is pneumatized. The apex of neural spine is transversely expanded and bears triangular lateral processes. The new taxon shares with Demandasaurus and the Wessex rebbachisaurid a high SPDL on the lateral side of the neural spine, separated from SPRL and SPOL. This possibly suggests derivation of Dzharatitanis from European rebbachisaurids. This is the second sauropod group identified in the assemblage of non-avian dinosaurs from the Bissekty Formation, in addition to a previously identified indeterminate titanosaurian.

Genus Dzharatitanis gen. nov.

Diagnosis: Differs from Limaysaurus and Tataouinea by convex anterior centrum articular surface. Differs from Lavocatisaurus and Limaysaurus by absence of pleurocoel on centrum. Differs from Comahuesaurus by ‘wing-like’ transverse process. Differs from Amazonsaurus by dorsally directed ventral surface of transverse process. Differs from Cathartesaura, Comahuesaurus, Demandasaurus, Itapeusaurus, and Tataouinea by shallow PRCDF. Differs from Cathartesaura, Itapeusaurus, Katepensaurus, and Tataouinea by absence of TPRL. Differs from Comahuesaurus, Demandasaurus, and Nigersaurus by absence of ventral contact between prezygapophyses. Differs from Comahuesaurus, Demandasaurus, Itapeusaurus, Limaysaurus, Nigersaurus, and Tataouinea by absence of ventral contact between postzygapophyses. Differs from Demandasaurus and Tataouinea by absence of hyposphenal ridge. Differs from Amazonsaurus, Cathartesaura, Katepensaurus, Limaysaurus, Nigersaurus, and Tataouinea by absence of SPRL and SPOL contact. Differs from Amazonsaurus, Cathartesaura, Katepensaurus, Limaysaurus, Nigersaurus, Tataouinea, and Rebbachisaurus by large SPDL on lateral side of neural spine separate from SPRL and SPOL. Differs from Amazonsaurus, Cathartesaura, Comahuesaurus, Itapeusaurus, Lavocatisaurus, and Limaysaurus by presence of lateral process of neural spine. Differs from Rebbachisaurus by proximodistally shorter and anteroposteriorly wider neural spine, which is convex anteriorly in lateral view, and by much wider PRSL.

Occurrence: Central Asia; Late Cretaceous (Turonian).

Etymology: From the Dzharakuduk locality in Uzbekistan and Greek τιτάν (titan), a pre-Olympian god in ancient Greek mythology. The generic name is in the feminine gender.

Dzharatitanis kingi sp. nov.

2015 Titanosauria indet.: figure 7 in [2].

Holotype: USNM 538127, nearly complete anterior caudal vertebra. Found by David J. Ward and Hans-Dieter Sues during the URBAC (Uzbekistan/Russian/British/American/Canadian) joint paleontological expedition working in Uzbekistan in 1997.

Type locality and horizon: Dzharakuduk, 32 km SW of Mynbulak, Navoi Viloyat, Uzbekistan. The Bissekty Formation, exposed along the Dzharakuduk escarpment, extends from approximately 42°06’22.60’’ N and 62°37’09.00’’ E to 42°05’44.22’’ N and 62°41’06.49’’ E. Age: Late Cretaceous (Turonian). For additional geological details see Redman and Leighton [5].

Etymology: In memory of our colleague and friend Dr. Christopher King (1943–2015) who did much work on the geology of Cretaceous strata in Central Asia.

Remarks: USNM 538127 is likely the first caudal vertebra because of its slightly opisthocoelous centrum and the absence of chevron facets. First caudals with opisthocoelous centra are known for several rebbachisaurids (see Comparison).

Abstract

A new genus of Entiminae, an endogean weevil of the tribe Otiorhynchini, Giavarhynchus Bellò, Osella & Ruzzier, gen. n., and its type species Giavarhynchus amicorum Bellò, Osella & Ruzzier, sp. n. are described. The new taxon is readily distinguished from all other members of the tribe due to the unique combination of lack of eyes, elongate rostrum with a ventral transverse furrow and excised lateral margins located at apical third, punctation of pronotum of two distinct sizes arranged in a distinctive pattern, interval 7 of elytra protruding from base of pronotum and crenulate basally, metafemora bearing a spine-like tooth much larger than that of pro- and mesofemora, female tibiae granulate on inner margin, bisinuous mesotibiae. The following synonymy is proposed: Nematocerus Reiche, 1849 (= Cyrtozemia Pascoe, 1872, syn. n.; = Holcorhinosoma Voss, 1939, syn. n.). New combinations are: Nematocerus cognatus (Marshall, 1916), comb. n.; Nematocerus dispar (Pascoe, 1872), comb. n.; Nematocerus pilipes (Morimoto, 2015), comb. n., all from Cyrtozemia; Nematocerus subtuberculatus (Voss, 1939), comb. n. from Holcorhinosoma. New tribal placement is: Pseudocratopus Hustache, 1921 from Otiorhynchini to Peritelini. New subgeneric placement is that of Otiorhynchus deceptorius Białooki, Germann & Pelletier, 2017 and of Otiorhynchus incisirostris Białooki, Germann & Pelletier, 2017 from Otiorhynchus (Lixorrhynchus) Reitter, 1914 to Otiorhynchus (Aranihus) Reitter, 1912.

Highlights

• First phylogenetic study including all six currently valid species of Brevoortia.

• The genus is monophyletic and species are grouped as pairs in three major clades.

• Divergence times were estimated and a biogeographic scenario is proposed.

• Gene flow occurs between different species within each major clade.

• Species-specific clades were not observed, and taxonomy of the genus needs revision.

Abstract

Brevoortia Gill 1861 is a genus of the Clupeidae (Teleostei) that includes six species of fishes commonly known as menhadens in eastern North America and “savelhas” or “saracas” in southeastern South America. Species of Brevoortia are important components of the marine food web of coastal ecosystems in the Atlantic and contribute significantly to fisheries. In this study, the first phylogenetic and biogeographic hypotheses including all species of Brevoortia are presented. A total of 113 specimens were analyzed using three molecular markers (two mitochondrial: COI and 16s; and one nuclear: RAG2). Maximum Parsimony, Maximum Likelihood and Bayesian Inference were employed to estimate phylogenetic relationships. A Bayesian multispecies coalescent approach was used to estimate a dated phylogeny, which supported biogeographic analyses of ancestral geographic ranges. Results corroborate previous hypotheses that the four North Atlantic species are grouped in two clades, one composed of B. tyrannus (Latrobe, 1802) and B. patronus Goode, 1878, and the second including B. smithi Hildebrand, 1941 and B. gunteri Hildebrand, 1948. The South Atlantic B. aurea (Spix and Agassiz, 1829) and B. pectinata (Jenyns, 1842) form a third clade, which is sister to the clade composed of B. smithi and B. gunteri. The monophyly and validity of the six nominal species of Brevoortia were not supported. Results also indicate that Brevoortia originated in the North Atlantic during the middle Miocene (about 15 Mya). A cooling event of the tropical Atlantic at around 10 Mya likely facilitated the range expansion of the genus to the South Atlantic, whereas a significant warming of the tropical Atlantic waters during the late Miocene at 6-7 Mya possibly promoted the isolation between the northern and southern counterparts of that ancestral lineage. The relevance of the Florida Peninsula in association with sea level fluctuations for the diversification within Brevoortia is also discussed.

Aethalopteryx strohlei Yakovlev sp. nov.

Diagnosis. It is necessary to note that the representatives of the genus Aethalopteryx have very simple genitalia, so it is not possible to make diagnostic distinctions basing on the male genital morphology. However, the species of the genus have significant external features: the size and color of the wings. The new species clearly differs from most species of the genus in the small size, and in this characteristic it is close to the East-African species group distributed in Somali and Kenia: A. steniptera (Hampson, 1916), A. simillima (Hampson, 1916), A. elf Yakovlev, 2011, and A. sulaki Yakovlev, 2011. But the dark, contrast color of the wings and the big round spot between veins CuA2 and CuP (postdiscally) are its clear distinction from the close small East-African species.

Distribution. Known only from South-Western Ethiopia (Debub Omo Zone of the Southern Nations, Nationalities, and People's Region).

Etymology. The new species is named after my colleague and friend Mr. Manfred Ströhle (Weiden), a remarkable connoisseur of the Palearctic and African Lepidoptera, the collector of the type series of the new species.

Tritodynamia bengalensis

Trivedi, Mitra & Ng, 2021

DOI: 10.11646/zootaxa.4938.3.3

Abstract

Tritodynamia bengalensis n. sp. is described on the basis of a male specimen dredged from the shallow coastal waters of West Bengal state, India. The new species is morphologically similar to T. bidentata Yang & Tang, 2005 and T. serratipes Anker & Ng, 2014, but can be distinguished by the carapace shape, dentition of the pollex, relative length of the dactylus of the third maxilliped, proportions of the propodus of the third pereopod, and structure of the male left gonopod. This is the first record of the genus Tritodynamia from India.
