Molecular Phylogenetic Estimates of Evolutionary Affinities and the First
PRIMARY RESEARCH PAPER | Philippine Journal of Systematic Biology DOI 10.26757/pjsb2020b14002 Molecular phylogenetic estimates of evolutionary affinities and the first reports of phenotypic variation in two secretive, endemic reptiles from the Romblon Island Group, central Philippines Camila G. Meneses1,2,*, Cameron D. Siler3,4, Juan Carlos T. Gonzalez1,2, Perry L. Wood, Jr.5,6, and Rafe M. Brown6 Abstract We report on the first molecular estimates of phylogenetic relationships of Brachymeles dalawangdaliri (Scincidae) and Pseudogekko isapa (Gekkonidae), and present new data on phenotypic variation in these two poorly known taxa, endemic to the Romblon Island Group of the central Philippines. Because both species were recently described on the basis of few, relatively older, museum specimens collected in the early 1970s (when preservation of genetic material was not yet standard practice in biodiversity field inventories), neither taxon has ever been included in modern molecular phylogenetic analyses. Likewise, because the original type series for each species consisted of only a few specimens, biologists have been unable to assess standard morphological variation in either taxon, or statistically assess the importance of characters contributing to their diagnoses and identification. Here we ameliorate both historical shortfalls. First, our new genetic data allowed us to perform novel molecular phylogenetic analyses aimed at elucidating the evolutionary relationships of these lineages; secondly, with population level phenotypic data, from the first statistical sample collected for either species, and including adults of both sexes. We reaffirm the distinctiveness of both named taxa as valid species, amend their diagnoses to facilitate the recognition of both, distinguish them from congeners, and consider the biogeographic affinities of both lineages. -
Genus Lycodon)
Zoologica Scripta Multilocus phylogeny reveals unexpected diversification patterns in Asian wolf snakes (genus Lycodon) CAMERON D. SILER,CARL H. OLIVEROS,ANSSI SANTANEN &RAFE M. BROWN Submitted: 6 September 2012 Siler, C. D., Oliveros, C. H., Santanen, A., Brown, R. M. (2013). Multilocus phylogeny Accepted: 8 December 2012 reveals unexpected diversification patterns in Asian wolf snakes (genus Lycodon). —Zoologica doi:10.1111/zsc.12007 Scripta, 42, 262–277. The diverse group of Asian wolf snakes of the genus Lycodon represents one of many poorly understood radiations of advanced snakes in the superfamily Colubroidea. Outside of three species having previously been represented in higher-level phylogenetic analyses, nothing is known of the relationships among species in this unique, moderately diverse, group. The genus occurs widely from central to Southeast Asia, and contains both widespread species to forms that are endemic to small islands. One-third of the diversity is found in the Philippine archipelago. Both morphological similarity and highly variable diagnostic characters have contributed to confusion over species-level diversity. Additionally, the placement of the genus among genera in the subfamily Colubrinae remains uncertain, although previous studies have supported a close relationship with the genus Dinodon. In this study, we provide the first estimate of phylogenetic relationships within the genus Lycodon using a new multi- locus data set. We provide statistical tests of monophyly based on biogeographic, morpho- logical and taxonomic hypotheses. With few exceptions, we are able to reject many of these hypotheses, indicating a need for taxonomic revisions and a reconsideration of the group's biogeography. Mapping of color patterns on our preferred phylogenetic tree suggests that banded and blotched types have evolved on multiple occasions in the history of the genus, whereas the solid-color (and possibly speckled) morphotype color patterns evolved only once. -

However, both species are inadequately diagnosed, based on a total of only five specimens. Here we provide brief taxonomic histories, discuss and clarify type localities, and redescribe each species using larger sample sizes and specimens well documented and collected during our recent biodiversity surveys. We include new information on morphological variation, distribution, ecology, and microhabitat. Scincid lizards of the genus Brachymeles are a predominately between 22 and 25 September 2009 at sea level (Fig. 1). In this Philippine radiation (25 recognized species currently) with paper, we redescribe both species and report new information only a single extralimital species (Brachymeles apus from on their natural history, ecology, and habitat. -

Reptilia: Squamata: Scincidae: Brachymeles): Taxonomic Revision of Pentadactyl Species Groups and Description of Three New Species
Herpetological Monographs, 24, 2010, 1–54 E 2010 by The Herpetologists’ League, Inc. PHYLOGENY-BASED SPECIES DELIMITATION IN PHILIPPINE SLENDER SKINKS (REPTILIA: SQUAMATA: SCINCIDAE: BRACHYMELES): TAXONOMIC REVISION OF PENTADACTYL SPECIES GROUPS AND DESCRIPTION OF THREE NEW SPECIES 1 CAMERON D. SILER AND RAFE M. BROWN Biodiversity Institute and Department of Ecology and Evolutionary Biology, University of Kansas, 1345 Jayhawk Boulevard, Lawrence, KS 66045-7593, USA ABSTRACT: We use data from external morphology and mitochondrial gene sequences to provide the basis for a taxonomic revision of two polytypic, pentadactyl Philippine species of scincid lizards of the genus Brachymeles. Although previous studies have noted significant morphological variation among island populations, the similarities in body size and scale pigmentation and pattern have led to the continued recognition of these two ‘‘widespread species.’’ A third, widespread, pentadactyl species, Brachymeles talinis, is known from Jolo Island and the central and northern Philippine islands. We evaluate both morphological and genetic data to define species limits in B. boulengeri, B. schadenbergi, and B. talinis. Our molecular and morphological data indicate each of the four subspecies of B. boulengeri, and both subspecies of B. schadenbergi, are genetically distinct, with ranges biogeographically circumscribed, differ from their congeners by numerous external morphological features, and therefore should be recognized as full species. Our morphological and genetic data necessitate the recognition of northern populations of B. talinis (from Luzon Island) as a new species and also reveal an unanticipated new species from Masbate Island. Finally, morphological data require the recognition of the B. talinis population from Jolo Island as a unique, new species. -
