ectuntio, Esox Hamilton [F.] 1822:212, 380 [An account of the fishes found in the river Ganges; ref. 2031] Smaller rivers and ponds of Gangetic provinces. No types known. There are discrepancies in the original description of Esox ectuntio, and the figure published later by Hora (1929 [ref. 23132]) further confuses the issue. Several authors (e.g., Mohr 1926 [ref. 15597], Mohr 1934 [ref. 16438], Herre 1944 [ref. 11023]) do not believe that Hamilton's description is of the Indian Zenarchopterus with the long upper jaw, and that the name Z. amblyurus (Bleeker 1849) should be used for this species. The type locality of Zenarchopterus hendersoni is doubtful (Collette and Su 1986:291 [ref. 5998]). Hamilton's original, unpublished illustration reproduced by Britz 2019:Pl. 120 [ref. 37532]. •Valid as Zenarchopterus ectuntio (Hamilton 1822) -- (Collette 1982 [ref. 5497], Ataur Rahman 1989:59 [ref. 24860], Talwar & Jhingran 1991:737 [ref. 20764], Kottelat et al. 1993:88 [ref. 23448], Rainboth 1996:174 [ref. 22772], Khan 2003:8 [ref. 27710], Ataur Rahman 2003:74 [ref. 31338], Collette 2004:20 [ref. 27583], Kottelat 2013:296 [ref. 32989]). Current status: Valid as Zenarchopterus ectuntio (Hamilton 1822). Zenarchopteridae. Distribution: India and Bangladesh to Thailand, Java, and Borneo. Habitat: freshwater, brackish.
