Diagnosis.

Length 60-70 mm, diameter 3.5 mm, 150-173 segments. Setae aa = 4.75-5.75 ab = 0.95-1.04 bc = 5.42-5.75 cd = 0.23-0.27 dd at segment 8; aa = 7.33-9 ab = 1-1.04 bc = 7.33-9 cd = 0.25-0.35 dd at segment 20. Male pores paired, at 10/11, slightly lateral to setae b lines. Spermathecal pores paired, at 7/8, at setae c lines. Genital markings paired, lateral to setae ab on segment 11, occasionally extending on to segment 12. Four gizzards in segments 13-16 or 14-17.
