Bioacoustics of Poropuntius deauratus

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.
