Two terminal bulbs separated by a long interspace, 0.6-1.8 times the length of distal bulb. Barbel length 76-92% SL. Short filaments 5-9 (less than 6% SL) without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than the rest. Some or all filaments with pigmented axes. Distal bulb long about twice as long as wide, with almost straight, parallel margins,1.5-2.5 times proximal-bulb length. Axis of stem and between bulbs with or without pigment; a black spot at proximal end of distal bulb in those with pigment. External chevron-shaped or roundish striated areas on stem unpigmented.
