The Palawan Pleistocene Aggregate Island Complex, a western Philippines island group, possesses a complex geologic history and numerous endemic vertebrates. On the basis of multiple unique morphological features, bolstered by genetic data supporting divergent lineages, we describe the first Philippine endemic species of Lygosoma from Palawan and Cuyo islands. This new semifossorial species is phenotypically similar to Lygosoma quadrupes, a widespread Southeast...

Twenty-six gekkonid lizards from the Philippines consisting of Cyrtodactylus philippinicus (n 5 12) and Gekko mindorensis (n 5 14) were examined for helminths. One species of Cestoda as cycticercoids and 6 species of Nematoda: Bakeria schadi, Meteterakis longispiculata, Parapharyngodon maplestoni, Physalopteroides sp., Pharyngodonidae gen. sp., and Physalopteridae larva, were found. Both gekkonid species harbored Parapharyngodon maplestoni and Physalopteroides sp. Parapharyngodon maplestoni had...

A new species of slender skink is described from the Philippines. The species is endemic to Lubang Island, and is assigned to the Brachymeles bonitae Complex based on phenotypic and genetic data. Specimens were collected from Lubang Island between 1991 and 2012, and were examined based on morphological data (qualitative traits, meristic counts, and mensural measurements). Published genetic sequence data from phylogenetic...

Studies of the diversity of Philippine amphibians and reptiles have resulted in the continued description of cryptic species. Species formerly thought to range across multiple recognized faunal regions are now considered to be assemblages of multiple unique species, each restricted to a single faunal region. This pattern continues to hold true when considering Philippine skinks of the genus Brachymeles. Recent studies have...

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was...

Standardization and repeatability is at the heart of all scientific research, yet very little literature exists to standardize mor- phometric measurements within vertebrate groups. This is particularly true for amphibians. Our study attempts to rectify this lack of methodological standardization for the measurement of morphological characters in anurans through an ex- tensive literature survey of 136 species descriptions representing 45 currently recognized...

Gecko lizards in the Philippines are quite diverse covering multiple genera, body types, and sizes, yet much of that diversity has gone undocumented.  Pseudogekko is an example of a little known Philippine endemic genus, with only four representative species.  Recent field surveys by Dr. Siler and colleagues have resulted in new  data indicating that these four species should be split into multiple others, based...

Recent phylogenetic analysis of false geckos, genus Pseudogekko, revealed unrecognized diversity within these exceedingly rare and enigmatic Philippine forest geckos. Newly available genetic datasets revealed that two of the four currently recognized species are complexes of multiple, deeply divergent evolutionary lineages. In this paper we evaluate species diversity in the Pseudogekko compresicorpus Complex and describe three new species in this unique clade of endemic Philippine...

We review the species of the Brachymeles bonitae Complex (B. bonitae and B. tridactylus) and describe an additional two new species in this highly specialized, limb-reduced, endemic Philippine clade of fossorial lizards. For more than 4 decades, B. bonitae has been recognized as a single ‘‘widespread’’ species, a perception that has persisted as a result of limited sampling and similar overall morphology...

We review the recent discovery of multiple populations of the enigmatic, semi-aquatic Sphenomorphus Group skink, Parvoscincus leucospilos Peters, and investigate the morphological and genetic diversity of isolated, allopatric populations of this unique skink. Our investigations support the recognition of four unique evolutionary lineages distributed across Luzon Island in the Philippines, three of which are herein described as new species (P. tikbalangi sp....

Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its...
