          Abstract

          An integrative taxonomic analysis using color pattern, morphology and 1497 base pairs of the ND2 mitochondrial geneand its five flanking tRNAs demonstrated that nine monophyletic species-level lineages occur within the Cyrtodactyluspulchellus complex (Cyrtodactylus pulchellus sensu strictu and C. macrotuberculatus) of the Thai-Malay Peninsula thathave a sequence divergence between them ranging from 5.9–16.8%. Additionally, each lineage is discretely diagnosablefrom one another based on morphology and color pattern and most occur in specific geographic regions (upland areas orislands) that prevent or greatly restrict interpopulation gene flow. Six of these lineages were masquerading under thenomen C. pulchellus and are described as the following: Cyrtodactylus astrum sp. nov. from northwestern PeninsularMalaysia and southwestern Thailand; C. langkawiensis sp. nov., at this point endemic to Langkawi Island, Malaysia; C.bintangrendah sp. nov., a lowland species surrounding the Banjaran (=mountain range) Bintang of northwesternPeninsular Malaysia; C. bintangtinggi sp. nov., endemic to the upland regions of the Banjaran Bintang of northwesternPeninsular Malaysia; C. trilatofasciatus sp. nov., endemic to upland regions of Cameron Highlands in the central portionof the Banjaran Titiwangsa in Peninsular Malaysia; and C. australotitiwangsaensis sp. nov. from the more southerlyupland regions of the Banjaran Titiwangsa. An additional species, Cyrtodactylus lekaguli sp. nov. from Satun, Trang, SuratThani, and Phang-nga provinces in southern Thailand, was identified on the basis of morphology and color pattern and is hypothesized to be part of a clade containing C. astrum sp. nov. and C. langkawiensis sp. nov.
