ALE separated by less than their radius. Postepigastric scutum long, almost rectangular, extending to nearly full length of abdomen. Leg spination: femur I p0-0-2, r1-1-0; tibiae I, II v4-4-1p; metatarsi: I v2-1p-2; II v3-0-2. Embolus long, abruptly bent at about half its length, slightly bent again near tip; conductor with large dorsal expansion.

FEMALE (PBI_OON 971, figs. 93–96): Total length 2.28. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum. Postepigastric scutum almost semicircular, fused to epigastric scutum. Leg spination: femora: I p0-0-2, r1-1-1; II p0-0-2, r1-1-0; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-0-2. Genitalic atrium oval, wide, anterior genitalic process widened at about half of atrial length.
