[edit] Taxonomy
In 1993, Pangasius was one of two genera (along with Helicophagus) in the family Pangasiidae. At this point, it was separated into four subgenera. Pangasius (Pangasianodon) included P. gigas and P. hypophthalmus and was diagnosed by the absence of mandibular barbels, the absence of teeth in adults and the presence of a single lobed swimbladder. Pangasius (Pteropangasius) included P. micronema and P. pleurotaenia and was diagnosed by four lobes in the swimbladder and with multiple segments in the last lobe. Pangasius (Neopangasius) included P. nieuwenhuisii, P. humeralis, P. lithostoma, P. kinabatanganensis, diagnosed by palatal teeth arranged in a single large patch and high vertebral counts. Pangasius (Pangasius) was the final subgenus and had no diagnostic features, containing the remaining species.[1] These subgeneric classifications were confirmed in 2000 except for Neopangasius, found to be polyphyletic and to be part of Pangasius (Pangasius), thus leaving three subgenera.[1]
Since then, the subgenera have been variably recognized as separate. P. gigas and P. hypophthalmus have been classified in the genus Pangasianodon, and P. micronemus and P. pleurotaenia in the genus Pseudolais (with Pteropangasius as a junior synonym).[2]
