Anterior ledge of paturon with slight tubercle at outer margin. Endites with ventral process relatively short, wide. Leg spination: femur I p0- 0-2; tibiae: I v4-4-0, II v4-2-0; metatarsi: I v2-2- 1p, II v2-2-0. Embolus long, narrow, distal twothirds directed obliquely; cymbium completely fused with bulb, no seam visible.
