DIAGNOSIS: Males resemble those of

but the palpal conductor is narrower, especially at the level of its prolateral spur (figs. 101–103); females have a much shorter postepigastric scutum (fig. 105).
MALE (PBI_OON 10683, figs. 97–104): Total length 1.69. Surface of elevated portion of pars cephalica appearing granulate; lateral margin without denticles. ALE separated by less than their radius. Postepigastric scutum almost semicircular, extending to about 3/4 of abdomen length. Leg spination: femur I p0-0-2, r1-1-0; tibiae: I v4-4-1p; II v4-4-0; metatarsi: I v2-1p-2; II v2-0-2. Embolus relatively short, weakly bent; conductor narrow throughout its length.
