Scientific Name

An examination of the holotype of Microhyla borneensis Parker 1928 revealed that this nomen applies to a miniaturized narrow-mouthed frog from Borneo that recently was described as Microhyla nepenthicola Das & Haas 2010. This is confirmed concordantly by body size of the female holotype of M. borneensis, and by its reduced extent of toe webbing and rather rounded, short snout profile. Consequently, the name M. nepenthicola is to be considered as a junior synonym of M. borneensis, and an old report of nepenthiphilous breeding habits of M. borneensis is therefore justified. A sympatric larger species usually treated as M. borneensis has no scientific name and is described here as M. malang sp. nov. The new species and M. borneensis are sister to each other, and together are closely related to M. mantheyi from Peninsular Malaysia. These three species are morphologically very similar, but can be distinguished by body size, color pattern, and extent of toe webbing. Phylogenetic relationships, miniaturization, and larval oral morphology in the genus Microhyla are discussed.

The genus Hassar (Doradidae) is diagnosed by a single exclusive feature: basioccipital with ventral ring-like arch surrounding aorta; and by the combination of several non-exclusive characters, including dark blotch in distal half of anterior branched rays of dorsal fin, and anteriormost postinfranuchal scutes reduced in size. Three nominal species are recognized and redescribed in Hassar: H. orestis from the Orinoco, Essequibo and Amazonas basins, excluding Tocantins and middle to upper Xingu drainages; H. wilderi from Tocantins; and H. affinis from northeastern Brazil, including Turiaçu, Pindaré-Mearim, Itapecuru and Parnaíba drainages. The nominal Hemidoras notospilus and Hassar ucayalensis are recognized as junior synonyms of Hassar orestis; Hassar woodi is considered a junior synonym of H. affinis; Hassar iheringi is recognized as a junior synonym of H. wilderi, and its type locality as originally reported is considered incorrect. A fourth new species, Hassar gabiru, is described from middle to upper Xingu river basin. Hassar is considered to be the sister taxon of Anduzedoras + Leptodoras. A detailed anatomical description and discussion of the phylogenetic relationships of Hassar among fimbriate-barbel doradids are provided.

Two New Species

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

Orbitolina daviesi Hofker, 1966 (family Orbitolinidae) was validly described and thoroughly illustrated from Thanetian limestones of Pakistan. Although its attribution to the genus Orbitolina d’Orbigny and any phylogenetic relationships with the Cretaceous taxa have been refuted shortly afterwards, the species has not been taxonomically revised since then. Karsella hottingeri Sirel, 1999 was established as new genus and new species from the Thanetian of Turkey, without taking into account J. Hofker’s publication. The original description and genus diagnosis of Karsella has meanwhile been emended to include the occurrence of a radial zone with septula that follow a zig-zag pattern and associated linear arrangement of the foramina, as well as a complex embryo. Orbitolina daviesi clearly displays these features and is here considered a species of the genus Karsella Sirel. Karsella hottingeri is regarded as a subjective junior synonym of O. daviesi Hofker and therefore, the only species of the genus is given as a new combination: Karsella daviesi (Hofker). From a suprageneric viewpoint, the two Paleogene genera Karsella Sirel and Cushmania Silvestri display a complex embryo and might belong to a new subfamily of the Orbitolinidae, phylogenetically different and unrelated to the lower-mid Cretaceous Orbitolininae.

A new, diminutive species of Rock Gecko, Cnemaspis shahruli sp. nov. from Penang Island, Penang; Pulau Jerejak, Penang; Pulau Pangkor, Perak; and the adjacent mainland at Sungai Sedim, Kedah was previously confused with juveniles of the sympatric, endemic species C. affinis (Stoliczka) on Penang Island. Cnemaspis shahruli sp. nov. is diagnosed from all other Southeast Asian Cnemaspis on the basis of several unique aspects of squamation, coloration, and body size. It is proposed that this new species has a more extensive mainland distribution than is presented here based on its southernmost record on Pulau Pangkor, Perak. A pattern of resource partitioning on the basis of body size, habitat, and activity period among sympatric species pairs of Cnemaspis is discussed.

A New Species

ABSTRACT A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new species described herein. Dasyloricaria have a restricted trans-Andean distribution, with D . filamentosa occurring at the lower and middle Magdalena, lower Cauca, and Sinu in Colombia, and lago Maracaibo basin in Colombia and Venezuela; D . latiura in the Atrato and the Tuyra basins in Colombia and Panama, respectively; and the new species in the upper and middle Magdalena basin in Colombia. New synonyms for D . filamentosa and D . latiura are proposed, and a lectotype is designated for the latter. Dasyloricaria is herein recognized as monophyletic, with D . filamentosa as the sister group of D . latiura , and the new speciesas sister to that clade. Spatuloricaria is hypothesized to be the sister group of Dasyloricaria based on synapomorphies of the neurocranium, branchial arches and external morphology features. The subtribe Rineloricariina was partially corroborated through the phylogenetic analysis. An identification key for the species of Dasyloricaria is provided.

A New Species

Molecular phylogenetic analyses of the sister species Sphenomorphus stellatus and S. praesignis based on the mitochondrial genes 12S and 16S rRNA recover the former as paraphyletic with respect to the latter in that a specimen of S. stellatus from the type locality in Peninsular Malaysia is more closely related to S. praesignis than to Indochinese populations of S. stellatus. Furthermore, the phylogeny indicates that the Indochinese populations represent two species, thus resulting in four major lineages within this clade. These relationships are consistent with multivariate and univariate analyses of morphological and discrete color pattern data which statistically define and diagnose the four lineages and together with the molecular data, provide the foundation for robust, testable, species-level hypotheses. As such, S. stellatus is herein restricted to Peninsular Malaysia; S. annamiticus is resurrected for the circum-continental populations ranging through southeastern Thailand, southern Cambodia, and southern Vietnam; a new species—S. preylangensis sp. nov.—is described from an isolated mountain, Phnom Chi, from the Prey Lang Wildlife Sanctuary in central Cambodia; and the taxonomy of S. praesignis remains unchanged. The description of S. preylangensis sp. nov. underscores the necessity to conserve this remnant of lowland evergreen rainforest in the Prey Lang Wildlife Sanctuary.

The North American leafhopper genus Erasmoneura Young was described as a subgenus of Erythroneura Fitch by Young (1952) to comprise the informal Erythroneura vulnerata Fitch species group previously recognized by Beamer (1938, 1946). Erasmoneura was recently elevated to generic status (Dietrich & Dmitriev, 2006) and revised (Dmitriev & Dietrich, 2007). In this paper, the male of Erasmoneura bipentagona (Beamer), previously known only from the female holotype and placed in the genus based on external similarity and features of wing venation (Young, 1952; Dietrich & Dmitriev, 2006; Dmitriev & Dietrich, 2007, see also the note for the species below), and a new species are described. A key for identification of all 13 species of the genus is provided. The key is based mainly on male genitalia characters. Although individual species have a characteristic color pattern, details and intensity may be highly variable both inter- and intraspecifically.

A little known tachinid genus, Metadrinomyia Shima, is revised based on four East Asian species including two new to science: M. flavifrons sp. nov. and M. xanthokolos sp. nov. The majority of the specimens used in this study were collected from low vegetation in the foothills of mountains in South Korea. The new species can be clearly distinguished from their congeners by their pruinosity, chaetotaxy and genitalic structures. A key, descriptions, photographs, and illustrations of the male genitalic structures are provided and the phylogenetic relationships among the species are investigated.

Neoceratitis is revised to include six species. N. albiseta, from Madagascar, is described as new. Trirhithrum lycii var. min-imum Bezzi, 1924 is a junior synonym of Ceratitis lycii Coquillett, 1901, new synonym. All known and suspected hostassociations are within the family Solanaceae, with one species (N. cyanescens) infesting tomatoes and several species ofSolanum, whereas the other species with known hosts are associated with Lycium spp. Neoceratitis is probably similar toTrirhithrum Bezzi and particularly to the little known Paratrirhithrum Shiraki. Redescriptions (description in the case of the new species) and illustrations are provided for all the species, and a key to all the species is also provided.

Three New Species

An integrative taxonomic analysis of the Ptychozoon lionotum group across its range in Indochina and Sundaland recovers P. lionotum sensu lato Annandale, 1905 as paraphyletic with respect to P. popaense Grismer, Wood, Thura, Grismer, Brown, & Stuart, 2018a and composed of four allopatric, genetically divergent, ND2 mitochondrial lineages. Multivariate and univariate analyses of continuous and discrete morphological and color pattern characters statistically and discretely diagnose each lineage from one another and together, with maximum likelihood and Bayesian inference analyses, provide the foundation for the recognition of each lineage as a new species—hypotheses corroborated with a Generalized Mixed Yule Coalescent species delimitation analysis. Ptychozoon cicakterbang sp. nov. ranges throughout Peninsular Malaysia to Pulau Natuna Besar, Indonesia; P. kabkaebin sp. nov. is endemic to northern and central Laos; and P. tokehos sp. nov. ranges from southern Thailand south of the Isthmus of Kra northward to Chiang Mai, fringing the Chao Phraya Basin and ranging southward through Cambodia to southern Vietnam. Ptychozoon lionotum sensu stricto ranges from northwestern Laos through southern Myanmar to eastern India. The phylogeographic structure within each species varies considerably with P. lionotum s.s. showing no genetic divergence across its 1,100 km range compared to P. cicakterbang sp. nov. showing upwards of 8.2% sequence divergence between syntopic individuals. Significant phylogeographic structure exists within P. tokehos sp. nov. and increased sampling throughout Thailand may require additional taxonomic changes within this species.
