An elusive new species of gymnophthalmid lizard (Cercosaurinae, Selvasaura) from the Andes of northern Peru

We describe a new species of Selvasaura from the montane forests of the eastern slopes of the Andes in northern Peru, based on external and hemipenial morphological characters and previous phylogenetic analyses. The new species can be differentiated from the other two Selvasaura species in having keeled dorsal scales usually flanked by longitudinal striations, in adults and juveniles; adult males with a yellow vertebral stripe bordered by broad dark brown stripes on each side and a unilobed hemipenis surrounded by the branches of the sulcus spermaticus. The description of the new species contributes information about new states of diagnostic characters of Selvasaura and natural history.

A New Species

We describe a new species of Enyalioides from a mid-elevation premontane forest in central Peru. This represents the seventh species of Enyalioides known to occur east of the Andes in South America; the other six species are E. cofanorum, E. laticeps, E. microlepis, E. palpebralis, E. praestabilis, and E. rubrigularis. Among other characters, the new species is distinguished from other Enyalioides by the combination of an orange blotch on the antehumeral region (in adult males), 30 or fewer longitudinal rows of dorsals in a transverse line between dorsolateral crests at midbody, ventral scales strongly keeled, and caudal scales heterogeneous in size on each autotomic segment. The new species is most similar morphologically to E. cofanorum and E. microlepis.

A New Species

A new species of the Asian leaf litter toad genus Leptobrachella is described from Guizhou Province, China. Molecular phylogenetic analyses support the new species as an independent lineage deeply nested in the Leptobrachella clade. The new species is distinguished from its congeners by a combination of the following morphological characters: body size medium (SVL 29.7–31.2 mm in five adult males); dorsal skin shagreened, some of the granules forming longitudinal short skin ridges; tympanum distinctly discernible, slightly concave; supra-axillary, femoral, pectoral and ventrolateral glands distinctly visible; absence of webbing and lateral fringes on fingers; toes with narrow lateral fringes but without webbing; heels overlapping when thighs are positioned at right angles to the body; tibia-tarsal articulation reaching the middle of eye when leg stretched forward. The discovery highlighted the underestimated species diversity in the Leptobrachella toads in southwestern China.

A New Species

We describe a new species of Megophryidae frog, Megophrys shunhuangensis sp. nov., from Hunan Province, Southern China. It can be distinguished from other known species in the subgenus Panophrys by morphological characters, bioacoustic data and a molecular divergence in the mitochondrial 16S rRNA gene similar to that found among other species of Panophrys. M. shunhuangensis sp. nov. is characterized by a relatively small body size, with adult females measuring 37.6 mm and adult males measuring 30.3–33.6 mm in snout to vent length; maxillary teeth present, vomerine teeth absent; tongue smooth, not notched behind; hindlimb slender, heels overlapping, tibio-tarsal articulation reaches forward between the nasal and tip of snout. Molecular phylogenetic analyses also show that M. sp. 6 from (Mao’er Shan, China) from Chen et al. (2017) and M. sp. 24 (Anjiangping and Mao’er Shan, China) from Liu et al. (2018) may be the same species as M. shunhuangensis sp. nov., we consequently speculate that the new species also distributed in Anjiangping and Mao’er Shan, China. At present, the genus Megophrys contains 85 species of which 48 species are distributed in China, and 30 belong to the subgenus Panophrys.

A New Species

Summary A new species of entomopathogenic nematode, Steinernema borjomiense n. sp., was isolated from the body of the host insect, Oryctes nasicornis (Coleoptera: Scarabaeidae), in Georgia, in the territory of Borjomi-Kharagauli. Morphological characters indicate that the new species is closely related to species of the feltiae-group. The infective juveniles are characterised by the following morphological characters: body length of 879 (777-989) μm, distance between the head and excretory pore = 72 (62-80) μm, pharynx length = 132 (122-142) μm, tail length = 70 (60-80) μm, ratio a = 26.3 (23.0-29.3), H% = 45 (40-51), D% = 54 (47-59), E% = 102 (95-115), and lateral fields consisting of seven ridges (eight incisures) at mid-body. Steinernema borjomiense n. sp. was molecularly characterised by sequencing three ribosomal regions (the ITS, the D2-D3 expansion domains and the 18S rRNA gene) and the mitochondrial COI gene. Phylogenetic analyses revealed that S. borjomiense n. sp. differs from all other known species of Steinernema and is a member of the monticolum-group.

A New Species

A new, and only the third known species of the Neotropical montane genus Oressinoma Doubleday is described—O. sorina n. sp., from the Andes of central Peru. It is distinguishable immediately from the other two congeners by the shape of the hindwing underside submarginal orange band, and by the male genitalia. The systematics of Oressinoma are reviewed. A preliminary analysis is carried out based on COI barcode confirming the separate specific status of O. sorina n. sp. in relation to other two congeners. Both barcode and genital morphology data suggest that the widespread O. typhla Doubleday may be a complex of allopatric or, locally parapatric species. The genus Oressinoma is the only neotropical member of the predominantly Australian subtribe Coenonymphina, represented in the entire Holarctic by one genus only—Coenonympha Hübner, considered as the putative sister-genus of Oressinoma. Their origins and relationships are briefly discussed.

A New Species

We report here the discovery of a new species of frog associated to the open areas of the highlands of the Parque Nacional da Serra dos Órgãos. The new species, Cycloramphus organensis is characterized by a unique skin texture, medium size (maximum male and female SVL 26.4 mm and 33.3 mm respectively), dorsal surfaces uniformly brick red colored, uniformly areolate skin on dorsum, pupil horizontal, iris with a menisc on upper margin; no fleshy tubercles on eyelid, tympanic annulus concealed beneath skin, macroglands not visible externally, fingers and toes without fringes and webs; supernumerary palmar and plantar tubercles absent, nuptial spines absent. Despite the presence of an iris menisc, a character shared by frogs of both genera Cycloramphus and Zachaenus Cope, the combination of morphological characters is so unique that the allocation of the species to any of these genera remains ambiguous. Consequently, we used additional molecular-based phylogenetic analyses to ascertain the position of the new taxon. The new species proved to be embedded within the genus Cycloramphus.

A New Species

Based on molecular phylogenetic analyses and morphological characters, a new species from Bangladesh, northern Vietnam, and southwestern China, Leptolejeunea nigra, is described. It is mostly similar to L. balansae but remarkable for having brownish black ocelli in its leaf lobes. In the molecular phylogeny, the samples of L. nigra are not nested within any clade and form an independent lineage. In particular, the molecular dating suggested that the divergence of L. nigra happened in time span of the formation of the Himalayas.

A New Species

Andaeschna is a small and poorly known genus of dragonflies that inhabits the Andes, from Venezuela to northwestern Argentina. Here we describe Andaeschna occidentalis sp. nov., first species of the genus recorded in the Western Andes, specifically from the Tatamá National Park in Colombia. Males of this species can be differentiated from the other four species in the genus by the unique shape of the distal segment of the vesica spermalis. Likewise, females can be distinguished by their smaller and broader cerci (slightly shorter than S9) and its subquadrate point. The discovery of this beautiful species expands the range of the genus, previously known only in the Eastern Andes.

Summary Laimaphelenchus spiflatus n. sp. isolated from declining Chinese pine, Pinus tabuliformis, is described and illustrated. The new species can be characterised by its relatively long body size of 1150 ± 108 (976-1437) μm for females and 1092 ± 78.6 (905-1235) μm for males, lateral field with four lines, females with a long vulval flap, and tail conoid, slightly ventrally curved and ending in a stalk having 8-12 projections when observed with SEM. Males are common, with 27.3 (23.4-28.8) μm long spicules having blunt (not well-developed) condylus and rostrum and truncate simple distal tip, and four caudal papillae. By having a vulval flap, four lateral lines and tail end with a stalk (without four tubercles), the new species comes close to L. preissii, L. simlaensis, and L. unituberculus, but can be differentiated from them by morphological characters and morphometric data. In phylogenetic analyses using near full length 18S and D2-D3 expansion segments of 28S rDNA, Laimaphelenchus spiflatus n. sp. appeared as an independent lineage separated from the other Laimaphelenchus spp. that are currently sequenced for their aforementioned genomic regions.

A New Species

All previous records of Pachycheles rugimanus A. Milne-Edwards, 1880, from the Brazilian coast are reviewed and prove to represent a new species, P. coelhoi sp. nov. (from Amapá, northern Brazilian coast), and P. ackleianus A. Milne-Edwards, 1880, a species already known from Brazil (from Pará to Rio de Janeiro). The new species is described and illustrated, and compared to its most similar congeners: P. rugimanus and P. ackleianus from the western Atlantic, and P. velerae Haig, 1960, from the eastern Pacific (Galapagos Island and Cocos Island). Pachycheles coelhoi sp. nov. is distinguishable from the other three species by a suite of morphological characters, which include the ornamentation of the carapace and chelipeds, and the shape of the third thoracic sternite. All previous records of P. rugimanus from Brazil are considered invalid.
