Description. MALE (holotype). Body 160 long (155 – 165 in 5 paratypes) and 95 wide (90 – 100). Idiosomal shields without ornamentation, soft idiosomal cuticle striated, without scales or tubercules. Distance between propodonotal and hysteronotal shields about 20. Propodonotal shield 38 long (38 – 42) and about 40 wide; posterolateral extensions encompassing bases of setae se and si. Pair of small platelets present posterior to setae se. Setae se at least 5 times longer than si. Hysteronotal shield 90 long (90 – 95); its length along midline 50 (50 – 55); with pair of deep lateral incisions at level of leg IV femora insertions. Posterior margin of hysteronotal shield with narrowly triangular median incision. Setae d 2 absent. Humeral shields without dorsal valves. Opisthosomal lobes about 30 long, widely separated from each other, lateral margins poorly sclerotized. Terminal cleft slightly longer than its greatest width, anterior end of cleft narrowly angular [= forms acute angle]. Lateral membranes narrow, entire. Interlobar membrane wide, entire; incision in interlobar membrane longitudinally ovate; terminal margin of these membranes near bases of setae h 3 slightly concave. Coxal fields III not closed. Genital arch shaped as a wide inverted V (Fig. 7). Aedeagus short, 5 – 6 long. Pair of adanal shields present, separated from each other. Diameter of adanal suckers 4 – 5. Cupules ih situated postero-lateral to adanal suckers. Legs III and IV subequal, 65 – 70 long. Femur III with 1 dorsal and 1 ventral weakly developed retrorse projections. Other projections on legs III and IV absent. Solenidion ω 1 absent on tarsi I. Tarsi IV straight.

Setae se at least 8 times longer than si. Hysteronotal shield 65 long and 40 wide. Setae d 2 absent. Humeral shields each with weakly developed dorsal valve. Coxal fields III not closed. Adanal shields widely separated from each other, weakly sclerotized. Legs III and IV subequal, about 80 long. Femora III and IV each with 1 dorsal and 1 ventral weakly developed retrorse projections. Other projections on posterior legs absent. Solenidion ω 1 absent on tarsi I.
