With robust new datasets from morphology and DNA sequences, we review the limbed, nonpentadactyl species of the Brachymeles samarensis complex (now known to include B. cebuensis, B. minimus, and B. lukbani), and describe five new species in this highly limb-reduced, endemic Philippine clade of scincid lizards. For more than four decades, B. samarensis has been recognized as a single ‘‘widespread’’ species. This...

We report 35 new amphibian and reptile distribution records for two regions within the southern Sierra Madre Mountain Range, Aurora Province, central Luzon Island, Philippines. Together with results of our previous survey work in Aurora, our new data result in a total of 82 amphibian and reptile species for the area. These results highlight the degree to which the island’s biodiversity continues...

Evolutionary simplification, or loss of complex characters, is a major theme in studies of body-form evolution. The apparently infrequent evolutionary reacquisition of complex characters has led to the assertion (Dollo’s Law) that once lost, complex characters may be impossible to re-evolve, at least via the exact same evolutionary process. Here, we provide one of the most comprehensive, fine-scale analyses of squamate body-form...

We report amphibian and reptile distribution records based on recent biodiversity surveys conducted at the Angat Watershed Reservation, Bulacan Province, Luzon Island, Philippines. This watershed constitutes the principal water source for Manila, the Philippines’ largest metropolitan area. As virtually nothing is known of the herpetological diversity of the immediate area and the surrounding Bulacan Province, all species recorded as part of our...

A new species of the scincid genus Larutia, L. penangensis sp. nov., from Pulau Pinang, Peninsular Malaysia is separated from all other congeners by having the unique characteristics of the complete absence of limbs, four supralabials, large body scales, and no banding or striping pattern. Additionally, it has the following unique combination of characters that further separates it from all congeners: a...

We describe a new species of lizard in the genus Gekko from Sibuyan Island in the Romblon Island group of the central Philippines. Although the new species is diagnosed from other Philippine Gekko by body size and shape, coloration, and multiple characteristics of external morphology, additional support for the recognition of the Sibuyan Gekko population as a distinct evolutionary lineage is garnered...

In this note, we question the hypothesis of a widespread case of mimicry, report on additional observations of the sympatric association of Bracca and Hemibungarus , and compare banding and color patterns between two subspecies of Hemibungarus and the sympatric lepidopteran from Luzon Island, Philippines. These observations suggest that a mismatch in color and pattern exists between the model (snake) and potential...

As humans continue to explore the last uncharted regions of the planet, discoveries of previously unknown species of large vertebrates have become infrequent. Here, we report on the discovery of a spectacular new species of giant, secretive, frugivorous, forest monitor lizard (Genus: Varanus) from the forests of the northern Philippines. Using data from morphology and mitochondrial and nuclear DNA sequences, we demonstrate...

Using a combination of fixed morphological character differences, mitochondrial DNA sequence data, and an estimate of phylogeny as our guide, we describe a new species of bent-toed gekkonid lizard (Genus: Cyrtodactylus) from southwestern Mindanao Island, and northeastern portions of the Sulu Archipelago, southern Philippines. The new species resembles C. annulatus, but differs from this and all other congeners by characteristics of external...

We review the taxonomic status of Philippine bent-toed geckos previously referred to Cyrtodactylus agusanensis. We delineate four evolutionary lineages within the C. agusanensis complex from the southeastern islands of the archipelago and describe three of these lineages as new species. The new species and true C. agusanensis are identified by numerous, nonoverlapping morphological characters and by allopatric ranges on separate islands. Our...
