Diagnosis

Barbel length less than 20% of standard length; barbel with 5 branches apparently arising together from stem; lateralmost pair of branches, which actually arise from base of mediolateral pair, usually shortest; mediolateral pair usually longest; diameter of stem distal to branches greater than that proximal to branches; stem solidly pigmented, pigment extending onto dorsal surface of terminal bulb; terminal bulb elongate and with an unpigmented tip usually directed dorsally; swollen ventrally, its length 2.0 - 2.5 times its thickness; a single terminal filament arising ventral to bulb tip, usually about as long as distal barbel, but occasionally minute.
