We provide an integrative taxonomic analysis of the Lipinia vittigera species complex from mainland Southeast Asia. Based on examination of external morphology, color pattern, and 681 base pairs of the cytochrome oxidase subunit I (COI) mitochondrial gene, we demonstrate the presence of four morphologically distinct lineages of Lipinia in Vietnam, Cambodia, Thailand, and Malaysia, showing a sequence divergence ranging 15.5% - 20.4%. All discovered lineages are discretely diagnosable from one another by a combination of scalation traits and color patterns. A review of the published distribution data and a re-examination of available type material revealed the following results: (1) distribution of L. vittigera (Boulenger, 1894) sensu stricto is restricted to Sundaland and the Thai-Malay Peninsula south of the Isthmus of Kra; (2) L. microcercus (Boettger, 1901) stat. nov. is elevated to full species rank; the species has a wide distribution from central and southern Vietnam across Cambodia to eastern Thailand; we regard Lygosoma vittigerum kronfanum Smith, 1922 and Leiolopisma pranensis Cochran, 1930 as its junior synonyms; (3) Lipinia trivittata sp. nov. occurs in hilly areas of southern Vietnam, Cambodia, and eastern Thailand; and (4) Lipinia vassilievi sp. nov. is currently known only from a narrow area along the Vietnamese-Cambodian border in the foothills of the central Annamite Mountain Range. We further provide an identification key for Lipinia occurring in mainland Southeast Asia. [ABSTRACT FROM AUTHOR]

The morphological and genetic variation of a wide-ranging Secret Toad-headed agama, Phrynocephalus mystaceus that inhabits sand deserts of south-eastern Europe, Middle East, Middle Asia, and western China is reviewed. Based on the morphological differences and high divergence in COI (mtDNA) gene sequences a new subspecies of Ph. mystaceus is described from Khorasan Razavi Province in Iran. Partial sequences of COI mtDNA gene of 31 specimens of Ph. mystaceus from 17 localities from all major parts of species range were analyzed. Genetic distances show a deep divergence between Ph. mystaceus khorasanus ssp. n. from Khorasan Razavi Province and all other populations of Ph. mystaceus. The new subspecies can be distinguished from other populations of Ph. mystaceus by a combination of several morphological features. Molecular and morphological analyses do not support the validity of other Ph. mystaceus subspecies described from Middle Asia and Caspian basin. Geographic variations in the Ph. mystaceus species complex and the status of previously described subspecies were discussed. [ABSTRACT FROM AUTHOR]
