Discussion
In this study, we follow Roberts (1998) and Dekkers (1975) in using Tetraodon as the genus for freshwater
pufferfishes in the Mekong Basin. If further study verifies separate lineages for Asian puffers distinct from that of
African puffers, the name Monotrete is available.
Tetraodon fangi was considered a valid species by Dekkers (1975), while Roberts (1998) considered T. fangi
and T. cochinchinensis to be synonyms of T. leiurus. Kottelat (2001) accepted T. cochinchinensis as a valid species
and recognized T. fangi as a synonym of T. cochinchinensis. However, examination of the holotype of T. fangi from
Xano Canal, Vi-thanh, Rach-Gia Province, southern Vietnam, and other specimens from Tram Chim, Tam Nong
