Phylogenetic structure and species boundaries in the mountain pitviper Ovophis monticola (Serpentes: Viperidae: Crotalinae) in Asia

2016). Molecular phylogeography of white-lipped tree viper (Trimeresurus; Viperidae). -Zoologica Scripta, 45, 252-262.The white-lipped tree viper (Trimeresurus albolabris) is one of the most common venomous snakes with medicine importance in South East Asia. To explore the genetic diversity, population structure and evolutionary history of Trimeresurus albolabris, we collected 98 samples from 27 localities covering its entire distribution. Two mitochondrial gene fragments (cyt-b and ND-4) and two nuclear genes (RAG-1 and NT-3) were sequenced and analysed. Bayesian inference and maximum-likelihood methods were employed to reconstruct the phylogenetic relationships among populations based on the two mitochondrial fragments, and the median-joining networks were depicted using nuclear genes. Divergence date and ancestral area were estimated, and the population demographic history was inferred. Both phylogenetic analyses consistently uncovered that Trimeresurus albolabris was monophyletics, with five geographically structured lineages. Divergence date and ancestral area estimation indicated that T. albolabris originated in northern Thailand and eastern Myanmar at c. 7.15 Ma. Population dynamics analyses showed the southern China lineage has experienced population expansion and contraction, but the others have not. Both the interglacial expansion and the highly heterogeneous habitats resulting from the uplift of the Plateau played a joint role in shaping the present distribution and population structure. The evolutionary history of T. albolabris can be explained by a pattern of two direction dispersal: first from North to South, and then from West to East.

“…Therefore, the addition of non-recombinant data sources (nuclear markers and/or morphology) to taxonomic analyses have proven to be highly informative in disentangling the lineages of species complexes (e.g. Malhotra et al 2011). Therefore, we employed an integrative taxonomic approach (i.e.…”

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.

“…This is especially true in tropical regions such as Southeast Asia, the dynamic and complex environmental history of which (Hall, , , , ; Woodruff, , ; Bird, Taylor & Hunt, ; Outlaw & Volker, ; Reddy, ; Cannon, Morley & Bush, ; Cannon, ; Gower et al ., ; Morley, ; Richardson, Costion & Muellner, ) has contributed greatly to the phylogenetic and phylogeographic structuring of a number of wide‐ranging clades thought previously to be single species (e.g. Matsui et al ., ; Stuart, ; Inger, Stuart & Iskandar, ; Wood et al ., , ; Grismer et al ., 2010b, 2012a; Malhotra et al ., ; Brown et al ., ; Johnson et al ., ; Nishikawa et al ., ; Loredo et al ., ). The infusion of a molecular phylogenetic data set into the morphology‐based classification of the wide‐ranging genus Hemiphyllodactylus not only contributes to this growing body of knowledge, but highlights the inherent tendency of morphological data sets to underestimate biodiversity in taxonomic revisions of widespread groups.…”

Integrative taxonomy uncovers high levels of cryptic species diversity inHemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) and the description of a new species from Peninsular Malaysia

Conserving the planet's biodiversity is greatly handicapped, in that only a small fraction of it (∼14-75%) has been described so far. Integrative taxonomy is making significant inroads in light of this challenge by incorporating multiple data sets across a wide range of disciplines that simultaneously elucidate phylogenetic structure and delimit species-level lineages within a unified species concept. An integrative taxonomic approach to the classification of the gekkonid genus Hemiphyllodactylus Bleeker, 1860 reveals that it is far more diverse than posited by a recent taxonomic revision based solely on morphology, and that it is composed of at least 19 species, most of which are montane upland or insular endemics. Three new species (Hemiphyllodactylus dushanensis sp. nov., Hemiphyllodactylus jinpingensis sp. nov., and Hemiphyllodactylus longlingensis sp. nov.) from southern China previously considered to be subspecies of Hemiphyllodactylus yunnanensis (Boulenger, 1903) are elevated to full species status, and 10 new species-level lineages ranging from Vietnam, Laos, Thailand, Myanmar, Peninsular Malaysia, the Philippines, and Indonesia are identified. One new species, Hemiphyllodactylus tehtarik sp. nov. from Gunung Tebu, Terengganu, Peninsular Malaysia, is described herein, and is differentiated from all other species of Hemiphyllodactylus on the basis of morphology, colour pattern, and an 18.1-31.5% sequence divergence from all other congeners. Hemiphyllodactylus larutensis (Boulenger, 1900) is removed from the synonymy of H. harterti (Werner, 1900). Using an integrative taxonomic approach imbues the revised classification of 849 Hemiphyllodactylus with more objectivity, stability, and phylogenetic history, while identifying undescribed species-level lineages in potential need of conservation.
