We revisit the question of species diversity among Mindanao Fanged Frogs of the Limnonectes magnus complex consisting of L. magnus, L. diuatus, L. ferneri, and a previously hypothesized putative new species, inferred in the first molecular phylogenetic studies of the genus almost 2 decades ago. Using a multilocus molecular deoxyribonucleic acid sequence data set and comprehensive sampling of 161 individuals from throughout...

Recent higher level phylogenetic analyses of gekkonid lizards of the genus Lepidodactylus uncovered an array of unrecognized species diversity, particularly within the Philippine archipelago. Novel phylogenetic analyses of multilocus data sets suggest that as many as five, previously undescribed, species-level lineages of Scaly-toed Geckos occur in just the northern portions of the archipelago. Here, we evaluate Lepidodactylus species diversity in the Lepidodactylus...

We describe a new species of fanged frog (genus Limnonectes) from Mindoro and Semirara Islands, of the Mindoro Pleistocene Aggregate Island Complex, of the central Philippines. Although morphologically indistinguishable from its closest relative, Limnonectes acanthi, of the Palawan faunal region, the two species can be readily diagnosed on the basis of spectral (dominant frequency) and temporal (pulse number and structure) properties of...

Combining the results from morphological and molecular analyses, we explore the taxonomy of the genus Achalinus from Southwest China. As a result, we describe two new species, A. panzhihuaensis sp. nov. and A. yangdatongi sp. nov. from southern Sichuan and southern Yunnan provinces, respectively, and we record a new country record, A. emilyae, from Guangxi Zhuang A. R.. The mitochondrial genealogy suggests...

Recent studies have highlighted the underestimated diversity of the genus Diploderma Hallowell, 1861 in the Hengduan Mountain Region in Southwest China, but much of the region remains poorly surveyed for reptile diversity. In this study we describe two new species of Diploderma from the upper Jinsha and middle Yalong River Valley, based on evaluations of morphological, genetic, and distribution data. The two...

The Philippine archipelago is an exceptionally biodiverse region that includes at least 112 species of land snakes from 41 genera and 12 families. Recently, Cyclocoridae (formerly Lamprophiidae: Cyclocorinae) was proposed as a distinct, Philippine-endemic family, containing four genera: Cyclocorus, Hologerrhum, Myersophis, and Oxyrhabdium. Here, we describe an additional cyclocorid genus and species, Levitonius mirus, new genus and species, from Samar and Leyte...

Cryptic diversity not only introduces confusion to taxonomic studies, but it also poses major challenges to conservation and environmental legislation. One such troubling group are the Mountain Dragons in the genus Diploderma in Southwest China. Previous studies have suggested that the genus contains considerable cryptic diversity, particularly in the D. flaviceps complex. Owing to taxonomic confusion, micro-endemic lineages are still neglected by...

While considerable progress has been made in the taxonomic studies of the genus Lycodon in Asia, questions remain to be clarified regarding the taxonomy of certain groups, particularly those containing species in China. Not only do many regions in China remain overlooked by herpetologists, resulting in the possibility of undiscovered new species, but the surveyed areas also have suspicious records of recognized...

The diversity of Philippine amphibians and reptiles has increased over the last few decades, in part due to re-evaluation of species formerly believed to be widespread. Many of these investigations of widespread species have uncovered multiple closely related cryptic lineages comprising species complexes, each restricted to individual Pleistocene Aggregate Island Complexes (PAICs). One group in particular for which widespread cryptic diversity has...

Philippine False Geckos (genus Pseudogekko) are secretive, delicate, slender-bodied, arboreal members of an obligate forest specialist clade that is substantially more species diverse than previously assumed. Over the last century, few species were added to this Philippine endemic genus. During the last decade, however, revisionary studies have resulted in the recognition of six new species. Several of these appear to be rare,...

We describe a new species of frog of the genus Platymantis Günther (subgenus Tirahanulap), from the east-central regions of the Philippines. It belongs to the the previously-defined P. hazelae Group) based on morphological and bioacoustic datasets. The new species is phenotypically and ecologically most similar to members of Tirahanulap, an assemblage of small-bodied arboreal frogs inhabiting montane forests of the central and...
