Morphology | Morphometrics
Barbel with medial branch arising from stem and a pair of lateral branches arising from medial branch distal to its origin; medial branch stout, almost as thick as stem, terminating in rounded tip lacking filaments; lateral branches tiny, short filaments; terminal bulb protruding strongly dorsad, ovoid in lateral profile; three long medial terminal filaments on distal end of bulb; a pair of dorso-lateral terminal filaments terminating in small but prominent spheroids (Ref. 45801).
