Meteterakis hurawensis n. sp. (Nematoda, Heterakidae) from the large intestine of Brachymeles orientalis and Brachymeles samad (Squamata, Scincidae) is described and illustrated. Meteterakis hurawensis n. sp. represents the 20th Oriental species assigned to the genus and is distinguished from other Oriental species by the distribution pattern of the caudal papillae (10 pairs total, 3 pairs of relatively large pedunculate papillae, 2 pairs...

With a published multilocus phylogenetic analysis as our guide, we use new data from the external phenotype and genetically defined distributions of evolutionary lineages to resolve species boundaries associated with the southwest Mindanao Stream Frogs, Sanguirana everetti (Boulenger 1882), its junior synonym, Rana mearnsi, Stejneger 1905, and the northeast Mindanao Stream Frogs, Sanguirana albotuberculata (Inger 1954). Consideration of relationships, distributions, type localities,...

We utilize robust geographical genetic sampling, and phylogenetic analysis of a new multilocus dataset to provide the first inference of relationships among Philippine Gonocephalus, combined with estimates of putative species diversity, in this almost unknown island radiation. Our results reveal startling levels of undocumented diversity, genetically partitioned at a number of geographical levels across the archipelago. We present the first survey of...

Cameron Siler, Katrina Menard, and the OU field crew (Austin Carriere, Elyse Ellsworth, Sierra Smith & Sam Eliades) arrived safely in Manilla on May 22 and had a day or so to explore the city while waiting for collaborators Dr. Duncan Irschick (UMass-Amherst) and Dr. Phillip Bergman (Clark University). They have now wrapped up collecting at their first site in Cayagan Province on Luzon Island and are now traveling...

We describe a new species of lizard in the genus Pseudogekko from Sibuyan and Tablas islands in the Romblon Island Group of the central Philippines. The new species is diagnosed from other Philippine Pseudogekko by body size and shape, color pattern, and multiple differences in scale characteristics. Pseudogekko isapa sp. nov. has been collected only twice from leaves of shrubs in forested...

We describe a new digitless scincid lizard of the genus Brachymeles from northern Luzon and Camiguin Norte islands in the Philippines. This species belongs to the Brachymeles bonitae Complex, and both molecular and morphological data confirm that this species is distinct from all other congeners. Formerly considered to be a single widespread species, this group of species has been the focus of...

We summarize all available amphibian and reptile species distribution data from the northeast Mindanao faunal region, including small islands associated with this subcenter of endemic vertebrate biodiversity. Together with all publicly available historical information from biodiversity repositories, we present new data from several major herpetological surveys, including recently conducted inventories on four major mountains of northeast Mindanao, and adjacent islands of Camiguin...

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...
