We review the Philippine frogs of the genus Leptobrachuim. All previous treatments have referred Philippine populations to L. hasseltii, a species we restrict to Java and Bali, Indonesia. We use external morphology, body proportions, color pattern, advertisement calls, and phylogenetic analysis of molecular sequence data to show that Philippine populations of Leptobrachium represent three distinct and formerly unrecognized evolutionary lineages, and we...

We use mitochondrial gene sequences to estimate relationships among Gekko populations from the northern Philippines. These data, plus morphological and biogeographical evidence, suggest that the Babuyan and Batanes island groups (north of Luzon Island) are inhabited by a minimum of six distinct evolutionary lineages, only two of which (Gekko porosus Taylor from the Batanes and Gekko crombota from Babuyan Claro) have been...

We describe a new species of gekkonid lizard on the basis of 21 recently acquired specimens from Babuyan Claro Island, Babuyan Islands group, northern Philippines. The new species differs from other Philippine Gekko by characteristics of external morphology, color pattern, and body size. The new species has been found low on trunks and buttresses of mature closed-canopy climax forest trees at low...

We describe a new species of forest frog (genus Platymantis) from 180–300 m above sea level on Mt. Lihidan in the northwestern part of Panay Island, Philippines. It is assigned to the Platymantis dorsalis species group and is distinguished from congeners by external morphology, various spectral and temporal components of the advertisement call, and a preference for terrestrial, limestone microhabitat. Unique morphological...

A new species of the genus Gekko is described from Panay, an island in the central-Philippines. The new species is characterized by a combination of the number of preanofemoral pores, dorsal tubercle rows, disposition of caudal tubercles and tubercles on dorsal surfaces of the limbs, number of subdigital lamellae, and distinct diagnostic white spots on head and dorsum. The new species is...
