Barbel with three branches arising together from stem; barbel stem pigmented only up to origin of branches; distal stem pigmented only in axis and small internal spots; terminal bulb roughly spheroidal with short streaks of pigment on the dorsal surface roughly outlining numerous unpigmented ovoids visible internally; ovoids not protruding above bulb surface; a single pair of laterally based terminal filaments on the dorsal tip of bulb and two or three medial filaments ventral to them; the dorsal pair longer, usually thicker, and with more side filaments than the medial filaments.
