Etymology: Bagarius: From the local name Vaghari, in Calcuta (Ref. 45335); dolichonema: Name 'dolichonema' from the Greek adjective 'dolikhos' and noun 'nēma', meaning 'long' and 'thread or yarn', in reference to the length of filamentous extensions with pectoral-fin
spines and caudal fins that are the longest in congeners except for B. bagarius.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 6; Afterflossenweichstrahlen: 8 - 10. This species is distinguished from its congeners by the following set of characters: lateral margin of frontal straight, not forming brow ridge; dorsal spine strong (width 9.9-14.1 times its length); weakly notched antero-dorsal margin on pterygiophore of first dorsal-fin; filamentous extensions of pectoral-fin spine beyond posterior of pelvic-fin base and some reaching anus; neural spines of 4tth-6th vertebrae immediately anterior to adipose fin distally slightly flattened; adipose-fin origin at vertical through or very slightly posterior to analfin origin; and caudal peduncle slender (3.8-4.6% SL) (Ref. 137734).
Body shape (shape guide): elongated; Cross section: oval.
