Abstract

A new species of Cyrtodactylus from Tak Province, Thailand, Cyrtodactylus amphipetraeus sp. nov., is described using an integrative taxonomic analysis based on morphology, color pattern, and the mitochondrial gene NADH dehydrogenase subunit 2 (ND2). The phylogenetic analyses place the new species within the C. sinyineensis group which was previously thought to be endemic to the Salween Basin in southern Myanmar. The phylogeny also places C. inthanon in the C. sinyneensis group which is expanded herein to also include the group’s sister species C. doisuthep. Along with C. amphipetraeus sp. nov., these are the first three species of the C. sinyineensis group to be found outside of Myanmar east of the Tenasserim Mountains. The Tenasserim Mountain region is discussed as an area of cladogeneic turnover.

Cyrtodactylus amphipetraeus sp. nov. 

Tak Bent-toed Gecko - ตุ๊กกายตาก

Distribution. Cyrtodactylus amphipetraeus sp. nov. is known only from the type locality at ... Cave, Mae Sot District, environs of Mae Sot, Tak Province, western Thailand; and ... Waterfall located approximately 4 km to the southwest from the cave (Fig. 1). 

Etymology. The specific epithet amphipetraeus is a Latinized adjective in nominative singular, derived from Greek amphi or ἀμφί (meaning of both kinds) and petra or πέτρα (for rock). The species name is given in reference to the remarkable natural history of this species which inhabits both limestone and granite rocks. The recommended vernacular name in English is Tak Bent-toed Gecko; in Thai is Tuk kai tak - ตุ๊กกายตาก.

Abstract

Continuous sampling in well studied areas may lead to new amphibian species discoveries, because population dynamics allow rare species to go unnoticed for years. Based on recent sampling of frogs in the northeastern region of Colombia, here we provide genetic, morphological, and bioacoustics evidence to support the description of a new species of the genus Pristimantis. Phylogenetic analysis suggests the new species is a member of the P. lacrimosus species group, a clade of 25 species that is highly diverse in Ecuador and Peru. This new species is more closely related to allopatric species from Peru and Guyana (i.e. P. olivaceus, P. pluvialis, P. pulchridormientes, and an undetermined Pristimantis). The new species has green-yellow coloration and a remarkable brown interocular band, which is unusual in the genus and which inspired the epithet. Pristimantis zorro sp. nov. has only been found at one locality at 1860 m s.a.l., on the eastern flank of the northern Cordillera Central in Department of Antioquia, Colombia. The new species inhabits the ecotone between the humid cloud forest and open areas. Repeated visits to the type locality suggest high variation in population abundance and/or species detection, because we have occasionally observed many individuals in briefs periods of times. In addition, we discuss the biogeographical and systematic implications of our species discovery.

Pristimantis zorro sp. nov. 

Etymology. The specific name is a patronym in reference to the character El Zorro (fox in Spanish). El Zorro is the secret identity of Don Diego de la Vega, a fictional hero created in 1919 by pulp writer Johnston McCulley. The character has a distinctive black garb, coat, hat and a mask that covers the top of the head from eye level upwards. The name alludes to the facial mask of the new species.

Resumen. El muestreo continuo en áreas bien estudiadas puede conducir a nuevos descubrimientos de especies de anfibios, debido a que la dinámica de las poblaciones permite que especies raras pasen desapercibidas durante años. Basado en unos muestreos recientes de ranas en la región nororiental de Colombia, aquí proporcionamos evidencia genética, morfológica y bioacústica que soportan la descripción de una nueva especie del género Pristimantis. El análisis filogenético sugiere que la nueva especie es miembro del grupo P. lacrimosus, un clado de 25 especies más diversas en Ecuador y Perú. Esta nueva especie está más estrechamente relacionada con especies alopátricas de Perú y Guyana (i.e. P. olivaceus, P. pluvialis, P. pulchridormientes y un Pristimantis no determinado). La nueva especie tiene una coloración verde-amarillo y una notable banda interocular marrón, que es inusual en el género y que inspiró el nombre de la nueva especie. Pristimantis zorro sp. nov. solo se ha encontrado en una localidad a 1860 m s.n.m., en el flanco oriental al norte de la Cordillera Central en el departamento de Antioquia, Colombia. La nueva especie habita el ecotono entre el bosque nublado húmedo y las áreas abiertas. Las visitas repetidas a la localidad tipo sugieren una gran variación en la abundancia de esta población y/o la detección de la especie, debido a que hemos observado individuos ocasionalmente y por breves períodos de tiempo. Adicionalmente discutimos las implicaciones biogeográficas y sistemáticas del descubrimiento de esta nueva especie.

[Herpetology • 2020] Leptobrachella neangi • A New Leptobrachella (Anura: Megophryidae) from the Cardamom Mountains of Cambodia

Leptobrachella neangi  Stuart & Rowley, 2020

DOI: 10.11646/zootaxa.4834.4.4

Abstract

The species-rich, megophryid frog genus Leptobrachella Smith, 1925 is distributed throughout the uplands of mainland Southeast Asia but is conspicuously absent from the Cardamom Mountains of southwestern Cambodia, where it has been known only by a single, undetermined metamorphic specimen collected nearly two decades ago. We report two adult female specimens of Leptobrachella collected a decade later at a second locality in the Cardamom Mountains and use mitochondrial DNA, nuclear DNA, and morphology to show that it represents a distinct species. Leptobrachella neangi sp. nov., named after its collector, is most closely related in mitochondrial and nuclear DNA to L. fuliginosa (Matsui, 2006) and L. melanoleuca (Matsui, 2006) from western Thailand, but has uncorrected pairwise distances of 8.69–10.99% in a mitochondrial 16S gene fragment from its two sister species. The new species is also readily distinguished from these and other congeners by having the combination of (1) SVL 35.4–36.3 mm in two adult females, (2) distinct dorsolateral glandular line absent, (2) belly transparent, immaculate purplish gray in life, creamy white in preservative, (3) dark inguinal blotch absent, (4) tympanum with black coloration extending from line under supratympanic fold, (5) dorsal skin with small, irregular bumps and ridges, and (6) iris coppery orange around pupil, fading to gold at periphery, not distinctly bicolored. The new species is the first named Leptobrachella from the Cardamom Mountains and the third from Cambodia.

Abstract

East Timor is an island located to the south of the Indonesian Archipelago and to the north of Australia, between the Indian and Pacific Oceans. It is included in the Coral Triangle and houses an amazing quantity of marine biodiversity. However, only two species of Syllidae (Annelida) have been reported up to now: Trypanosyllis migueli and T. devae. Based on a small collection from the Australian Museum, we have identified nine genera and 17 species: Brevicirrosyllis mariae, Opisthodonta morena, Sphaerosyllis densopapillata, Branchiosyllis australis, B. exilis, B. maculata, B. verruculosa, Haplosyllis djiboutiensis, Opisthosyllis brunnea, Syllis alternata, S. broomensis, S. corallicola, S. erikae, S. gerlachi, S. hyalina, S. setoensis and Trypanosyllis luzonensis. This is the first record of S. gerlachi outside the Indian Ocean, and B. mariae, O. morena, S. densopapillata, H. djiboutiensis, S. corallicola and S. erikae have not been previously reported in tropical Asia. A specimen of Parahaplosyllis sp. could not be identified due to its poor condition. Three species belonging to Syllis are herein described as new: Syllis cambuk n. sp. has a large size body, with anterior segments much wider and shorter than posterior ones, long whip-shaped dorsal cirri and bidentate midbody and posterior chaetae, with both teeth equal in size and shape; Syllis hampirmenyatu n. sp. has three chaetae per posterior parapodium, with short and wide blades appearing to be fused with shafts, but still clearly distinguishable from each other, bidentate, with proximal tooth clearly smaller and thinner than distal one; and Syllis maganda n. sp. is easily recognizable because of its spectacular orange and blue colouration, only observable in living specimens, with broad transverse red stripes on the dorsum forming a distinctive pattern and red spots on the cirri and prostomium observable in both living and fixed specimens. Additionally, Philippine samples from the Museo Nacional de Ciencias Naturales of Madrid have been examined corresponding to S. maganda n. sp. A Philippine specimen of S. maganda n. sp. had a small unidentified specimen of Haplosyllis attached to a posterior dorsal cirrus, which is the first documented case of such an interaction between two species of Syllidae. This provisionally called Haplosyllis sp. is characterized by its simple chaetae with short spur and two very long, distinct curved teeth, very close to each other. A regenerated prostomium and a stolon were also found in other Philippine specimens of S. maganda n. sp.

Lasiopogon bitumineus McKnight 

in McKnight & Cannings, 2020. 

DOI: 10.11646/zootaxa.4835.1.1 

Abstract

Nearctic species of Lasiopogon Loew comprising the bivittatus section (the bivittatus group sensu Cannings 2002) are revised, with the description of 13 new species, elevation of one subspecies to species, and redescriptions of 13 previously described taxa. An updated key to western Nearctic Lasiopogon adults is provided, as are notes on taxonomy, distribution, phylogeny, and ecology. A Bayesian species tree for 67 species of Lasiopogon is estimated from one mitochondrial (COI) and three nuclear protein-coding loci (AATS, PEPCK, Wg), and compared to a previously published morphology-based phylogeny. The following new species of Lasiopogon are described (assigned to the bivittatus section except as noted): Lasiopogon anaphlecter sp. nov., L. apoecus sp. nov., L. asilomar sp. nov., L. bitumineus sp. nov., L. canningsi sp. nov., L. condylophorus sp. nov., L. esau sp. nov., L. karli sp. nov. (assigned to cinereus group of opaculus section), L. nelsoni sp. nov., L. odontotus sp. nov., L. sierra sp. nov., L. tumulicola sp. nov., L. wilcoxi sp. nov.; L. puyallupi Cole & Wilcox 1938 stat. nov. is elevated from subspecies; and the following previously described species are considered valid: L. actius Melander 1923, L. albidus Cole & Wilcox 1938, L. arenicola (Osten Sacken 1877), L. bivittatus Loew 1866, L. californicus Cole & Wilcox 1938, L. dimicki Cole & Wilcox 1938, L. drabicolum Cole 1916, L. gabrieli Cole & Wilcox 1938, L. littoris Cole 1924, L. ripicola Melander 1923, L. willametti Cole & Wilcox 1938, L. zonatus Cole & Wilcox 1938. The species L. martinensis Cole & Wilcox 1938 is considered valid but transferred to the tetragrammus group of the opaculus section.

Species richness in the genus Miniopterus has been greatly under-reported, with a large number of taxa having been discovered and described in the past two decades. Using molecular, standard morphometrics and acoustic data, we present evidence for the existence of a new species in Mozambique and neighbouring Malawi. Based on cytochrome b (cyt b) and cytochrome oxidase I (COI), the new species is sister to M. minor, from which it is readily distinguishable by its larger size (including non-overlapping forearm measurements, allowing separation in the field). It is distinguishable from sympatric M. mossambicus, itself a newly described taxon from Mozambique, by forearm measurements and a peach-orange wash to the skin around the eyes. In external appearance, it is most similar to M. fraterculus, from which it is only reliably identifiable by multivariate analysis of craniodental features and by a genetic distance of 6.4% in the cyt b gene; the two species also occupy widely differing geographic ranges. The type locality of the new species is Mount Gorongosa, and all known records are from large mountains in central and northern Mozambique and southern Malawi. Further research is required to establish its geographic range and understand its basic ecology. Considering its relatively restricted distribution to threatened montane habitats, we suggest that its global conservation status be urgently assessed.

Abstract

Ichtyoselmis macrantha subsp. porphyrantha J. Y. Shen & Q. B. Gong a new subspecies from West Yunnan and North Myanmar is described. The new subspecies differs from Ichtyoselmis macrantha subsp. macrantha by its outer petals purplish red and with minute red-purple spots as well as transversal lines on the apical swollen margin, and inner petals white with red-purple spots. It is distributed well to the Southwest of the distribution area of I. macrantha subsp. macrantha.

Begonia colliculata Souvann. & Lanors., sp. nov.

(Section Platycentrum). 

Begonia colliculata is similar to Begonia hekouensis S.H.Huang, but differs in having ver-rucous peduncles (vs densely villous), bracts with a strigose margin (vs ciliate), sparsely strigose tepals (vs villous), a sparsely strigose and colliculate ovary with a broadly falcate-elongate dorsal wing (vs densely purplish brown villous and not colliculate, dorsal wing ligulate). It is also similar to B. croceaC.-I Peng but differs in having a cane-like stem (vs stemless), leave blade ovate-lanceolate (vs broadly ovate), inflorescences arising from axils on the stem (vs arising directly from the horizontal rhizome) and anthers elliptic-oblong, apex rounded (vs fusiform-obovate, apex acuminate) (Table 1).

Entomology.— The specific epithet “colliculata”refers to the colliculate surface of the ovary and fruit.

Vernacular.—  ສົ້ມກຸ້ງແດງ - Som koung deang  (Red begonia).

Abstract

We examine the phylogenetic relationships among salamanders of the genus Bolitoglossa (Eladinea) distributed in the Amazonian basin of northern Peru and southern Ecuador and assess species diversity based on morphological and phylogenetic analyses. We infer a molecular phylogeny using sequences from two mitochondrial (Cytb, 16S) and two nuclear genes (RAG–1, POMC). We find two well-supported subclades, one including [B. altamazonica + B. peruviana] + B. awajun sp. n., and the other including Bolitoglossa sp. Ituxi + Bolitoglossa sp. Jurúa. Ecuadorian lineages form divergent clades from the Peruvian lineages. Accordingly, Ecuadorian populations previously assigned to Bolitoglossa peruviana sensu lato are treated as members of a Bolitoglossa equatoriana species complex. A newly defined Bolitoglossa altamazonica species complex contains only populations from the Amazonian rainforest of Peru. Maximum likelihood and Bayesian Inference analyses confirm the phylogenetic placement of B. altamazonica and B. peruviana, and support recognition of a related new species of Bolitoglossa. The uncorrected genetic distances between the new species and B. altamazonica are 6.5% for Cytb and 4.9% for 16S; and the uncorrected genetic distances between the new species and B. peruviana are 8.0% for Cytb and 3.9% for 16S. Additionally, analyses of nuclear gene sequences show no haplotype sharing between the new species and closely related species. The new species is distinguished from its congeners by a combination of the following morphological characters: (1) Standard length mean 37.7 mm in males (range 32.0–42.2; n=5) and 41.4 mm in females (range 34.9–48.2; n=6); (2) in life, dorsal coloration uniformly brown with a dark brown triangular marking between the eyes or some irregular light cream spots or patches on the head, back and flanks; (3) iris pale golden; (4) in preservative, dark brown venter with cream mottlings or moderate-sized blotches on the gular region, belly, cloacal region and tail; (5) tips of third finger and third toe protuberant and pointed with nearly complete webbing on the hands and feet; (6) 11–26 maxillary teeth and 8–24 vomerine teeth. Given that the syntypes of B. altamazonica are lost, we designate a neotype for B. altamazonica from Allpahuayo Mishana National Reserve, Loreto department, Peru. Newly collected specimens from ~30 km NE from Moyobamba (type locality of B. peruviana) provide a better understanding of B. peruviana and enable us to show that it is the sister taxon of B. altamazonica. The new species is known from pre-montane forests in Cordillera Escalera Regional Conservation Area, Cordillera Azul National Park and Shucshuyacu, San Martin department, Peru at 485–1311 m elevation,  ~75 km SE from Moyobamba. Bolitoglossa awajun sp. n. is the fourth endemic species of salamander from Peru.

 Bolitoglossa awajun sp. n. 

 Suggested English name: Awajun salamander 

Suggested Spanish name: Salamandra Awajún

Etymology: The specific epithet awajun refers to the Peruvian ethnic group known as “Awajún” or “Aguaruna” native inhabitants of Amazonian rainforests in Loreto, Amazonas, San Martin and Cajamarca departments. The name is treated as a noun in apposition.
