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.
