Relevant Information:

This species was referred to as Hara filamentosa mainly due to it having an exceedingly long extension to the top ray of the caudal fin, which was diagnosed as a prominent feature by Blyth in 1860 in his description of Hara filamentosa. However, Erethistes (Hara) filamentosa as diagnosed by Ng & Kottelat (2007) comes from an area further south and therefore from a different drainage system. In Ferraris 2007, Erithistes has been moved back to its original placement in the Sisoridae family which had been moved there by de Pinna in 1996, along with Conta, Erethistoides, Hara and Pseudolaguvia. Listed in Fishbase as Hara longissima which may or may not be a synonym of Etithistes longissima. At the present moment (Jan. 2010) there are still conflicting views on this species and family. Remarks: Ferraris (2007) stated that the Erethistidae be moved back into the Sisoridae family.
