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. Prostates glandular, hemi-ovoidal, sessile; vas deferens short, joining prostate at anterior and inner side. Spermathecae paired in segment 8; atrium cushion like ectal widening of spermathecal duct, partly embedded in body wall in segment 8, several times as wide as spermathecal duct.

Distribution.

India: Kerala: District Kasaragod: Adakasthala, Kadamgod, Klayikkod, Kottencheri, Nileshwar, Pandigaya, Periyathaduka, Plachikkara, Ranipuram and Veeramalakunnu (all new records) (Fig. 2); Karnataka: District Uttara Kannada (North Kanara): Talewadi, Castle Rock ( Stephenson 1917); District Shivamogga (Shimoga): Batkal, Kogar, Nakkalu ( Blanchart and Julka 1997).

Remarks.
