Thismia sumatrana Suetsugu & Tsukaya

in Suetsugu, Tsukaya, Nurainas & Okada, 2018. 

Abstract
A new species of the mycoheterotrophic genus Thismia Griff. (Thismiaceae), Thismia sumatrana Suetsugu & Tsukaya, from West Sumatra, Indonesia, is described, based on a rehydrated herbarium specimen from National Museum of Nature and Science, Japan. Thismia sumatrana is closely related to T.clavigera (Becc.) F.Muell. but is distinguished by a much larger flower.

Keywords: Thismia, taxonomy, new species, mycoheterotrophy, Sumatra

Thismia sumatrana Suetsugu & Tsukaya, sp. nov.

Diagnosis: Thismia sumatrana differs from its close relative T. clavigera, in having a much larger flower (ca. 8 cm vs. ca. 2.8 cm long).


Distribution: It is known from only a single collection comprising of one flowering and one fruiting individual.
 Thismia sumatrana was collected from a forest floor beside a rheophytic zone along Anak Air Ganggu (Ganggu Stream), 0°33'S, 100°21'E, at Sipisang Village, Padang Pariaman, West Sumatra, Indonesia. The area was covered by mixed primary and secondary forest along a stream, where relatively natural conditions remained. For example, there were many individuals of a rare and large herbaceous plant, Amorphophallus titanum (Becc.) Becc. (Araceae). In addition, many individuals of a rheophytic plant, Furtadoa sumatrensis M.Hotta (Araceae), grew on small rocks both in the stream and on the stream bank (Mori and Okada 2001).

Hygrocybe indica 

in Latha & Manimohan, 2018. 

Abstract
Hygrocybe indica sp. nov. is described based on specimens collected from Kerala State, India. Morphology-based methods and phylogenetic analyses of sequences of the internal transcribed spacer (nrITS) and nuclear large subunit (nrLSU) of the ribosomal RNA gene were employed to confirm the novelty of this species. The phylogenetic relationship inferred from independent nrLSU and nrITS sequence data matrices confirmed the difference of this new species from other species of Hygrocybe for which DNA sequences are available. The phylogenetic analyses clearly assigned H. indica to the subgenus Hygrocybe. A comprehensive description, photographs of the basidiocarps and the microstructures, and comparisons with morphologically similar and phylogenetically related species and phylograms to depict the placement of the new species are provided.

Abstract
Indocnemis marijanmatoki sp. n. (holotype ♂, 1503 m a.s.l., Hon Ba Nature Reserve, Nha Trang city, Khanh Hoa Province, central Vietnam) is described based on both sexes. The morphological variation of Indocnemis orang (Förster in Laidlaw, 1907) is discussed and its distribution in Vietnam updated.

Keywords: Indocnemis, new species, Odonata, Platycnemididae, Vietnam

Indocnemis marijanmatoki sp. n.

Diagnosis: The new species differs from I. orang with a combination of the following characters: in the male, the marking on dorsum of synthorax is small, shield-shaped; S9–10 entirely black; cerci short, of the length as S10, without a robust basal spine; paraproct entirely black. In the female, the posterior pronotal lobe of the prothorax is rather small, semicircular-shaped.

Etymology: Marijanmatoki, a noun in the genitive case, after Marijan Matok (born 28 March 1972) of Ulm-Söflingen, Germany, in appreciation of his support of the author’s odonatological research in Vietnam through the International Dragonfly Fund.

Habitat and ecology: At the type locality, the new species was found at a narrow (2–3 m wide), shallow stream with sandy bottom. Specimens were collected in April, which otherwise is early for other dragonflies and damselflies, so only Anotogaster sp. was found at the same stream. At the two localities where the new species was found, I. marijanmatoki sp. n. and I. orang occur at quite different elevations. The new species occurs at very high elevations, from 1,400–1,500 m a.s.l., while I. orang is usually found in the areas ranging from 300–600 m a.s.l.

Aulacus bicolor Jennings & Austin

in Jennings, Parslow & Austin, 2018. 

Abstract
The Aulacidae is a small family of Hymenoptera that are parasitic on wood-boring beetles and wasps. They have a worldwide distribution but are generally poorly studied, particularly for the southern hemisphere. This study is part of a series that aims to describe the Australian fauna which is relatively species-rich compared with other regions. We describe 39 new Aulacus species from eastern mainland Australia and Tasmania: A. anici Jennings & Austin, sp. nov., A. aquilus Jennings & Austin, sp. nov., A. bamagensis Jennings & Austin, sp. nov., A. bashfordi Jennings & Austin, sp. nov., A. bicolor Jennings & Austin, sp. nov., A. boonanghiensis Jennings & Parslow, sp. nov., A. brabyi Jennings & Austin, sp. nov., A. broadi Jennings & Austin, sp. nov., A. burnsi Jennings & Austin, sp. nov., A. confusus Jennings & Parslow, sp. nov., A. dandenongensis Jennings & Austin, sp. nov., A. deansi Jennings & Austin, sp. nov., A. doddi Jennings & Austin, sp. nov., A. froggatti Jennings & Austin, sp. nov., A. glorious Jennings & Parslow, sp. nov., A. hackeri Jennings & Austin, sp. nov., A. insularis Jennings & Austin, sp. nov., A. jamberoo Jennings & Parslow, sp. nov., A. kittelae Jennings & Austin, sp. nov., A. kiwarrakensis Jennings & Austin, sp. nov., A. leai Jennings & Austin, sp. nov., A. mareebaensis Jennings & Austin, sp. nov., A. naumanni Jennings & Austin, sp. nov., A. nebo Jennings & Austin, sp. nov., A. neboissi Jennings & Austin, sp. nov., A. obcordellus Jennings & Parslow, sp. nov., A. pallidus Jennings & Austin, sp. nov., A. quickei Jennings & Austin, sp. nov., A. rieki Jennings & Austin, sp. nov., A. scitulus Jennings & Parslow, sp. nov., A. simsoni Jennings & Austin, sp. nov., A. smithi Jennings & Austin, sp. nov., A. tasmanicus Jennings & Austin, sp. nov., A. tiernyi Jennings & Austin, sp. nov., A. umbackae Jennings & Austin, sp. nov., A. walkeri Jennings & Parslow, sp. nov., A. warraensis Jennings & Austin, sp. nov., A. willamsi Jennings & Austin, sp. nov., and A. wrightae Jennings & Austin, sp. nov. We also redescribe 14 species: A. albimanus (Kieffer), A. aroueti (Girault), A. atriceps Kieffer, A. elegans (Kieffer), A. festivus (Kieffer), A. flavicornis (Kieffer), A. flavimanus (Kieffer), A. fuscicornis Cameron, A. longiventris (Kieffer), A. minutus Crosskey, A. pallidicaudis (Cameron), A. planiceps (Szépligeti), A. truncatus (Kieffer), and A. vespiformis (Kieffer). As well, A. nigriventris (Kieffer) is synonymised with A. albimanus (Kieffer) syn nov. This brings to 60 the total number of species known from Australia (71 for the Australian region), although one species, A. biroi (Szépligeti), remains incertae sedis. A key to Australian Aulacus species is presented, along with notes on taxonomic history and host relationships.

Nyctimantis rugiceps  Boulenger, 1882

in Camargo de Souza, Rivera-Correa, Padial & Castroviejo-Fisher, 2018. 

Nyctimantis rugiceps Boulenger, 1882 (Fig. 1A) is a Neotropical treefrog (Duellman & Trueb 1976; Faivovich et al. 2005) known only from disjunct localities in Amazonian Colombia, Ecuador, and Peru (Pérez-Villota et al. 2009). This species has the skin of the skull co-ossified and reproduces—including calling behavior, egg deposition and tadpole development—in water-filled tree or bamboo cavities (Duellman & Trueb 1976; Duellman 1978). Given its secretive behavior, this is a poorly known species and, as noted by Duellman (1978: 169), “the major clue to the life history of Nyctimantis is the calling behavior of the males”. Unfortunately, the only quantitative description of the advertisement call of N. rugiceps is a brief passage in Duellman (1978) based on four specimens from Santa Cecilia, Ecuador, where important variables are missing (e.g., call duration). More importantly, graphs illustrating the waveform and spectrogram are missing. Considering these limitations and the importance of advertisement calls to the study of anurans (Köhler et al. 2017), we provide a quantitative description using a call recording obtained in Leticia, Amazonas, Colombia.

Astroceramus kintana Mah, 2018


Abstract
Modern goniasterids are the most numerous of living asteroids in terms of described genera and species and they have important ecological roles from shallow to deep-water marine habitats. Recent MNHN expeditions and historical collections in the USNM have resulted in the discovery of 18 new species, three new genera and multiple new occurrence records from the western Indian Ocean region including Madagascar, Glorioso and Mayotte islands, Walters Shoal, South Africa, and Somalia. This report provides the first significant contribution to knowledge of deep-sea Asteroidea from the Indian Ocean since the late 20th Century. Several deep-sea species, previously known from the North Pacific are now reported from the western Indian Ocean. Gut contents from Stellaster and Ogmaster indicate deposit feeding. Feeding modes of this and other deep-sea species are discussed. Comments are made on fossil members of included taxa. A checklist of Indian Ocean Goniasteridae is also included.

in Orr, Pitts & Griswold, 2018. 

Abstract
Anthophora (Micranthophora) comprises the largest subgenus of Anthophora in the Western Hemisphere, with 26 species. Though previously synonymized with the Anthophora (Heliophila), Anthophora (Micranthophora) is here confirmed as a subgenus, morphological and multi-gene molecular phylogenetic evidence refute this and the synonymy of A. (Micranthophora) to A. (Heliophila) is formally rejected. Characters for (Micranthophora) are given and a key to species is provided. Seven new species are described: Anthophora (Micranthophora) caudataOrr, sp. nov.; Anthophora (Micranthophora) chihuahua Orr, sp. nov.; Anthophora (Micranthophora) escalanteOrr, sp. nov.; Anthophora (Micranthophora) parkeri Orr, sp. nov.; Anthophora (Micranthophora) raraOrr, sp. nov.; Anthophora (Micranthophora) striataOrr, sp. nov.; and Anthophora (Micranthophora) timberlakeiOrr, sp. nov. Further, four new synonyms are enacted: A. arthuri and A. flexipes to A. albata, A. nigritula to A. exigua, and A. xanthochlora to A. pachyodonta. Distributional and phenological data, as well as known details of nesting biology and floral specialization, are provided. Future research directions and species of potential conservation interest are also discussed.

Microhyla beilunensis 
Zhang, Fei, Ye, Wang, Wang & Jiang, 2018


Abstract 
We described a new species, Microhyla beilunensis sp. nov., from Zhejiang Province of China. Phylogenetic analyses based on the mitochondrial 12S, 16S and CO1 gene sequences suggested that the new taxon was distinctly separated from its congeners and closed to M. mixtura and M. okinavensis. Morphologically, the new species could be identified from its congeners except M. mixtura by several characters: (1) rudimentary webs on toe base; (2) absence of disks and dorsal median longitudinal grooves on finger tips; (3) presence of disks and dorsal median longitudinal grooves on toe tips. As well, the new species could be identified from topotype M. mixtura by the combination of characters: (1) apart from the stripes, bar-shaped and oval-shaped patterns, the rounded spots present on the dorsum of body and legs; (2) the outer metacarpal tubercles prominently larger than the inner one; (3) of males, the ratios of HW, IND, UEW and LAW to SVL of the new species were significantly larger than those of M. mixtura (P < 0.01), and the ratios of SL, IOD, LAHL, HLL, TL, TFL and FL to SVL of the new species were significantly less than those of M. mixtura (P < 0.05).

Microhyla beilunensis sp. nov.
 Microhyla mixtura: Fei, Ye, Xie and Cai. 1999. 
Chin Zool Res, Beijing (Beilun, Zhejiang): 239−240.

Etymology: This specific name beilunensis is a Latinize toponymic adjective that refers to Beilun District, Ningbo City, Zhejiang Province of China, where the new species was collected. For the common name, we suggest Beilun Pygmy frog (English) and Bei lun ji wa (Chinese).

Diagnosis: The new species is allocated to the genus Microhyla, because it is consistent with the generic diagnostic characters: relatively small body size; maxillary and vomerine teeth absent; vomer divided into two parts and disappearing at the posterior edge of the choana; tongue posteriorly rounded; skin smooth or with tubercles; tympanum hidden or indistinct; 1−2 row of horizontal skin ridges on the palate; fingers without webbing; toes webbed or free of webbing; 2 or 3 metacarpal tubercles; the absence of supernumerary tubercles below the base of fingers and toes; the absence of skin ridge or skin projection between the subarticular tubercles of toes III and IV (Parker, 1934; Fei et al., 2005, 2009).

Distribution and habits:Microhyla beilunensis sp. nov. is now known only from the type locality, Beilun District, Ningbo City, Zhejiang Province of China. This species lives in the water pits or ponds about 3 m diameter or adjacent grass thickets, subterranean holes and mud pits in the mountainous regions at elevation 1400 m a.s.l. The male frogs make vibrating calls on the last 10 days of March. Small tadpoles seen in the early April would dive to the bottom when disturbed. On the 9th April 1998, four gravid females, egg groups, and small tadpoles were found. Mating of females and males took place in the pond of imitated natural eco-breeding in Chengdu (Fei et al., 1999). Small tadpoles were found in the last 10 days April. It took 60 days for the fertilized eggs to finish metamorphosis. Newly metamorphic frogs were 8−10 mm. Sympatric species of amphibians in the Beilun District during the surveys includes Hynobius yiwuensis, Echinotriton chinhaiensis, Bufo gargarizans, Rana zhenhaiensis, Pelophylax nigromaculatus, Sylvirana latouchii, Fejervarya multistriata.

Abstract
Tacca khanhhoaensis V.S. Dang & Vuong (Taccaceae) is described as a new species from Hon Ba Nature Reserve in southern Vietnam. This species is morphologically similar to T. chantrieri and T. ampliplacenta but differs from its allies by several salient characters: size of leaves and petioles, inflorescent much shorter leaves, number of flowers, stigma lobes, buds colour. A description, conservation assessment, together with photographs and a key to the species of Tacca in Vietnam are presented.

Tacca khanhhoaensis V.S. Dang & Vuong, sp. nov.

Diagnosis: Tacca khanhhoaensis is similar to Tacca chantrieri André in leaf shape and bracts, but differs from it in having shorter leaves (up to 45 cm vs. 60 cm long) and petioles (up to 22 cm vs. 43 cm long), inflorescences with fewer flowers (5 to 10 vs. 15 to 25), 2-lobed stigma vs. 3-lobed stigma and dark red buds vs. green buds. The new species is also somewhat similar to T. ampliplacenta L. Zhang & Q.-J. Li of China, but differs from it by having smaller leaves (30–45 × 10–14 cm vs. 55 cm long) and fruits (3–4 × 1.5–2 cm vs. 4–6 × 2–2.5 cm) and very short petioles (22 cm vs. 50 cm long), inflorescent much shorter leaves (vs. longer), number of flowers (5 to 10 vs. 25) and dark red buds vs. black-purple.

Distribution and habitat: Tacca khanhhoaensis is only known from Hon Ba Nature Reserve, Khanh Hoa Province, southern Vietnam. It was growing under the shade of the canopy on dry soil or close to the stream, where Aporosa tetragona Tagane & V.S. Dang, Bambusa sp., Barringtonia macrostachya (Jack) Kurz, Calamus sp., Croton sp., Desmos sp., Goniothalamus flagellistylus Tagane & V.S. Dang, Ixora sp., Microcos tomentosa Sm., Phyllanthus reticulatus Poir. and Streblus indicus (Bureau) Corner are dominant.

Etymology: The name of this species is derived from the name of the province Khanh Hoa, where the species was discovered.

Scinax caprarius Acosta-Galvis, 2018


Abstract 
As a result of the exploration of post-conflict areas in the Colombia BIO project, a new species of green bones frog of the genus Scinax, assignable to the clade Scinax ruber, is described. The species is endemic to the peripheral sub-Andean forests of the middle Magdalena valley in Colombia. This biological entity was previously identified in the scientific literature as Scinax “A”. The new species is recognizable by its average size 28.6-31.1 mm, chromatic pattern and its particular mating call that is similar to the sound of a goat bleating; each vocalization has a duration of 0.21-0.47 s, with a dominant frequency between 2184-3218 Hz.; its larval characteristics were evaluated, which altogether made it possible to clearly differentiate it from other species in the genus in the trans-Andean region of Colombia. With the description of this species, 18 frogs of the genus Scinax are currently recognized in the Colombian territory.

Castro, Beard, Ochoa, Bauchan & Feres, 2018


Abstract
The Amazon and the Cerrado are the two largest biomes in Brazil, and combined represent nearly 70% of the natural vegetation in the country. Recent surveys of the mite fauna present in these two biomes have revealed a great number of new species. In this paper, we describe the adult females, deutonymphs, protonymphs, larvae and eggs of two new species of Tenuipalpidae (Trombidiformes: Tetranychoidea), Tenuipalpus protium sp. nov., collected on Protium heptaphyllum (Burseraceae), and Tenuipalpus kitajimai sp. nov., collected on an unidentified plant of the family Sapindaceae, from the Cerrado and the Amazon Rainforest, respectively. Females of these two new species bear two distinct cuticular crests on the dorsal opisthosoma, one transverse crest anteriorly and one longitudinal crest mesally. The ontogenetic changes in the idiosomal and leg chaetotaxy of all stages are presented for both species. Adult males are not known for either species.

Philippinozercon makilingensis 

Gerdeman, Garcia, Herczak & Klompen, 2018


Abstract
The generic classification of millipede associated Heterozerconidae in the Oriental region is revised. The genus Allozercon Vitzthum is re-diagnosed and Asioheterozercon Fain is designated as an subjective junior synonym of Allozercon.Philippinozercon gen. nov., with the type species P. makilingensis sp. nov., is described for all instars. This genus may be endemic for the Philippines, but is quite widespread in that country. All immature instars are described, making this the second species of Heterozerconidae known for all instars. The morphology of the immatures is compared with that of immatures of the temperate species Narceoheterozercon ohioensis and unnamed species from Brazil and Thailand. All immatures were collected from millipede frass and litter, never from millipedes. Adults are associated with millipedes in the family Trigoniulidae (Spirobolida).

Holopothrips sp.

in Lindner, Ferrari, Mound & Cavalleri. 2018.

Abstract
The genus Holopothrips represents the main Neotropical group of thrips associated with plant galls, and several of the 36 currently described species are known to induce or invade galls of other organisms. The existence of several Holopothrips specimens in collections that do not belong to any of the already described species, allied to the absence of basic biological information for several species, such as host plants and habit, shows that the current knowledge on the genus is severely lacking. Here we start addressing these problems, by describing 24 new species: H. acrioris, H. atlanticus, H. bicolor, H. brevicapitatum, H. cardosoi, H. curiosus, H. flavisetis, H. graziae, H. inconspicuus, H. infestans, H. irregularis, H. johanseni, H. kaminskii, H. longihamus, H. longisetus, H. magnus, H. maiae, H. nigrisetis, H. nigrum, H. punctatus, H. reticulatus, H. singularis, H. spermathecus, H. varicolor. This study also includes information on galls for several species; an updated and illustrated key to species; and comments on the morphological diversity of the group. With that, we hope to lay the taxonomic and morphological bases for future studies in this group, focusing on its diversity, ecology and phylogenetic relationships.

ABSTRACT
 A new species of snakehead fish Channa royi sp. nov., has been described based on 21 specimens collected from the South, Middle and North Andaman Islands, India. It is distinguished from all its congeners by a greenish-grey dorsum, pale brown to black pectoral fin with 2-3 inconspicuous semicircular bands, a series of 7-9 obliquely-arranged, saddle-like, dark olive to grey oblique streaks on green background on upper half of the body, 42-45 pored lateral-line scales, 12-13 branched caudal rays, 6-7 pre-dorsal scales, 43 vertebrae, two rows of teeth on the lower jaw, an outer row of numerous minute slender, pointed teeth and single inner row of large uniform sized teeth without any large canine like teeth on the anterior fourth of the lower jaw. Phylogenetically C. royi sp. nov. is closely related to C. harcourtbutleri, with a genetic distance (K2-P) of 2.4-2.8%, but morphologically differs in having greater inter-orbital width, fewer pelvic-fin rays (5 vs. 5-7, mode 6); fewer caudal-fin rays (ii- i, 10-12, i-ii vs. ii, 15, ii); more pre-dorsal scales (6-7 vs. 4) and fewer mid row lateral-line scales (9-13 vs. 15-16). Though Channa royi sp. nov. is a part of C. gachua species-group, it differs from the topotypic C. gachua from Bengal with higher pair-wise sequence distance of 19.5-20.9%.

Channa royi, sp. nov. Praveenraj & Knight
Common name: Andaman Emerald Snakehead 

Diagnosis: Channa royi sp. nov. is distinguished from all other species of the genus Channa belonging to the Channa gachua species-group by a combination of following characters: unique greenish-grey dorsum; upper half of body with a series of 7-9 obliquely-arranged, saddle-like, dark olive to grey oblique streaks on green background; throat with marbled pattern; 34-38 dorsal-fin rays; 22-25 anal-fin rays; 42-45 pored scales on body; 1-3 scales on caudal fin base; 3½ scales above lateral line and 6½ scales below lateral line; 6-7 pre-dorsal scales; 43 vertebrae; two rows of teeth on the lower jaw, single outer row of numerous minute slender pointed teeth and single inner row of enlarged uniform teeth without any large canine like teeth on anterior-fourth of the lower jaw; two rows of teeth on palatine; outer row with numerous minute sharp slender teeth and inner row with 4 to 6 large canine like teeth and pectoral fins pale brown to black in adults with 2-3 pale grey to black inconspicuous semicircular bands.
....

Etymology: The species is named after Dr. S. Dam Roy, in appreciation for his immense encouragement and support for the exploration of the freshwater fishes of Andaman and Nicobar Islands. The species name is formed as a noun in the masculine genitive singular. The common name ‘Andaman emerald snakehead’ is given considering its unique greenish dorsum. 

Distribution: Channa royi sp. nov. is currently known only from South, Middle and North Andaman Islands, India and is abundant in ditches, ponds and hill streams of the sampled locations. The holotype was collected from clear, slow flowing water with cobble substrate without much aquatic vegetation.

Zamia paucifoliolata Calonje


in Calonje, López-Gallego &Castro. 2018. 

Abstract
Zamia paucifoliolata, a new cycad species from the Pacific lowlands of Valle del Cauca, Colombia, is described and illustrated. It is distinguished from other species of Zamia by having an underground stem typically bearing large solitary leaves with eighteen or fewer leaflets, villous strobilar axes, microsporangia borne on both the abaxial and adaxial side of microsporophylls, and seeds that are longer than 18 mm. It is compared to Z. pyrophylla, Z. cunaria, and Z. ipetiensis, species which it most closely resembles.

Zamia paucifoliolata Calonje sp. nov.

 Diagnosis:— Zamia paucifoliolata most closely resembles Z. pyrophylla from which it is distinguished by the light green leaf flushes, the leaflets that are broader and less numerous, the fewer and larger mature megasporophylls and seeds, and the lighter colored pollen strobili.

FIGURE 3.  Zamia paucifoliolata in its natural habitat at the type locality.
 A. Middle leaflets collected from plants at different stages of development. B. Juvenile plant. C. Adult plant with seed strobilus, showing yellow clay soils in which the species grows. D. Adult plant in habitat with Jonatan Castro (left) and Michael Calonje (right). E. The largest leaf yet observed for this species, measuring 285 cm long and carrying 18 leaflets.

 Etymology:— The specific epithet refers to the small numbers of maximum leaflets produced by leaves of this species which are among the least numerous of any species of Zamia. Leaves on adult plants carry between 10 and 18 leaflets (n=135 leaves, mode=10, mean 11.6), and only a few species with broad, prominently-veined leaflets carry the same number or fewer leaflets. Namely, Z. wallisii Braun (1875: 376), with the broadest leaflets in the genus, has leaves with a maximum of 11 leaflets, Z. dressleri Stevenson (1993: 6) carries up to 14 leaflets, and Z. imperialis Taylor et al. (2008: 421) similarly carries a maximum of 18 leaflets. The small number of leaflets carried by leaves of Z.paucifoliolata readily distinguishes it from its putative relatives Z. cunaria, Z. ipetiensis, and Z. pyrophylla, all of which carry a maximum of 32 leaflets.

Ecology:— The known populations of the species appear to be viable, with a larger proportion of juveniles compared to adults, i.e. evidence of reproduction and regeneration. Plants are distributed in highly dense patches on the understory of the forest, on moderately steep slopes and near small streams. Little is known about leaf phenology, frequency or rate of strobilus production or germination time. Mature seed strobili with ripe seeds have been observed in February and May, whereas pollen strobili have only been observed in late August. Immature seed strobili have been observed in June, August, and September. There is no information yet about microrganisms associated to roots or species interactions involved in pollination or seed dispersal, but a good proportion of viable seeds has been observed in female strobili. The typical herbivores associated to Zamia species, Eumaeus Hübner (1819: 67), have not been observed yet either, but there were signs of herbivory by leaf miners. A permanent plot has been established in one of the populations to monitor population dynamics and other ecological aspects of the species.
