Notes.
The P. deauratus clade contained 56 specimens of six nominal species, P. normani, P. deauratus, P. bolovenensis, P. lobocheiloides, P. smedleyi, and P. solitus, collected from a wide area including the Eastern Gulf of Thailand drainages, Malay Peninsula, Mekong Delta, Kratie – Stung Treng, Khorat Plateau, and Annam ecoregions, including type localities.
Molecular data from specimens originally identified as P. bolovenensis, P. lobocheiloides, and P. solitus (GenBank: Song et al. 2017) are from specimens identified morphologically by Kang et al. (2016), who also discussed variation in these forms and in P. consternans. Kang et al. (2016) considered all to be P. bolovenensis. Our results agree with the conspecificity demonstrated by Kang et al. (2016) but place P. bolovenensis in the synonymy of P. deauratus. Roberts (1998) had correctly treated P. consternans and P. lobocheiloides, later named by Kottelat (2000), as ecomorphs of P. bolovenensis. Our five specimens of P. normani were collected in the same small area as the type locality.
Poropuntius deauratus occurs over a large geographic area and shows considerable variation in shape and color (Fig. 4 B – H) as well as in the structural traits related to feeding morphology.
Distribution.
Poropuntius deauratus is found in the Western Malaysia, Malay Peninsula Eastern Slope, Eastern Gulf of Thailand, Mekong Delta, Kratie-Stung Treng, Khorat, northern Annam, and southern Annam ecoregions.
