New Ichthyophis species from Indochina (Gymnophiona, Ichthyophiidae): 1. The unstriped forms with descriptions of three new species and the redescriptions of I. acuminatus Taylor, 1960, I. youngorum Taylor, 1960 and I. laosensis Taylor, 1969

A new species of Oligodon Fitzinger, 1826 from the Langbian Plateau, southern Vietnam, with additional information on Oligodon annamensis Leviton, 1953 (Squamata: Colubridae)

“…nov. brings the number of Oligodon species known for Vietnam to 24, thus making the country a local center of Oligodon diversity in Southeast Asia. Our work provides further evidence on high herpetofaunal diversity and endemism in Langbian Plateau, which mostly has been discovered only recently (e.g., Chen et al, 2018;Duong et al, 2018;Geissler et al, 2015a;Geissler et al, 2015b;Hartmann et al, 2013;Nazarov et al, 2012;Orlov, Nguyen & Ho, 2008;Orlov et al, 2012;Pauwels et al, 2018;Poyarkov et al, 2014;Poyarkov et al, 2015a;Poyarkov et al, 2015b;Poyarkov et al, 2017;Poyarkov et al, 2019a;Poyarkov et al, 2019b;Poyarkov & Vasilieva, 2011;Rowley et al, 2010;Rowley et al, 2011;Rowley et al, 2016;Stuart et al, 2011;Vassilieva et al, 2014). Despite the impressive increase in species discoveries in the recent years, many isolated montane areas of the Truong Son Mountains, such as the Langbian Plateau, still remain insufficiently studied and likely cradle even more unknown biodiversity.…”

“…1, locality 1). This montane area is characterized by high levels of local endemism (Nazarov et al, 2012;Poyarkov et al, 2014;Poyarkov et al, 2015a;Poyarkov et al, 2015b;Poyarkov et al, 2017;Poyarkov et al, 2019b;Stuart et al, 2011;Rowley et al, 2016); further research is needed to clarify the distribution of the new species.…”

“…Located in middle of the Southeast Asian biodiversity hotspot, the Langbian Plateau is known as a local center for herpetofaunal endemism. It is inhabited by numerous species of amphibians and reptiles, many of which were only described recently Nazarov et al, 2012;Poyarkov et al, 2014;Poyarkov et al, 2015a;Poyarkov et al, 2015b;Poyarkov et al, 2017;Poyarkov et al, 2019b;Stuart et al, 2011;Rowley et al, 2016;Vassilieva et al, 2014). The Kukri Snakes of the genus Oligodon Fitzinger, 1826, are one of the most speciose and taxonomically problematic colubrid snake groups distributed in South and Southeast Asia, with over 79 species described (Green, Orlov & Murphy, 2010;Wallach, Williams & Boundy, 2014;Uetz, Freed & Hošek, 2019).…”

Molecular, morphological and acoustic assessment of the genus Ophryophryne (Anura, Megophryidae) from Langbian Plateau, southern Vietnam, with description of a new species

“…The Langbian Plateau is known for its high herpetofaunal diversity and endemism, a significant portion of which has been discovered only recently (e.g., Orlov et al 2008, 2012, Rowley et al 2010c, 2011a, 2011b, 2016, Stuart et al 2011, Poyarkov [Paiarkov] and Vassilieva 2011, Nazarov et al 2012, Chan et al 2013, Hartmann et al 2013, Geissler et al 2014, 2015, Vassilieva et al 2014, Poyarkov et al 2014, 2015a, 2015b). Despite this increase in species discoveries, many areas of the Annamites have received little scientific attention and are very likely to host further previously unknown diversity.…”

Species delimitation of crab-eating frogs (Fejervarya cancrivora complex) clarifies taxonomy and geographic distributions in mainland Southeast Asia

“…Southeast Asia harbors high levels of amphibian species diversity and endemism (Brown and Stuart 2012), and new species continue to be discovered and described (e.g., Geissler et al 2014; Phimmachak et al 2015; Sheridan and Stuart 2018). Moreover, recent evaluations of morphological and molecular diversity of Southeast Asian amphibians have routinely shown that long-recognized geographically widespread single species actually represent complexes of cryptic species (Stuart et al 2006b; Aowphol et al 2013; Phimmachak et al 2015; Sheridan and Stuart 2018).…”
