Material examined
The specimen which closely matches the measurements and anatomical characters of the original description is designated herein as the lectotype ZMH V3600 (Fig. 9). The type locality of this species is Quilon, Travancore. Paralectotype: ZMH V3600.1 (7 adults and 16 juveniles) same locality with lectotype. Additional reference specimens: 4 adults (ZMH V3601) from Calicut, Malapuram, Tiruvallur. 13 adults (ZMH V3607) from Malabar. 1 juvenile (ZMH V9173) from Narayan, Vordeviu Dicu. 2 juveniles (ZMH V9172) from Narayan, Vordeviu Dicu. 1 subadult (NHM 1922: 4: 20: 2) from banks of the Harngi, Madapur (Coorg). 1 juvenile (NHM 1922: 4: 20: 3) from Forests of Dubari, Fraserpett (Coorg).
Lectotype designation proposed herewith is necessary to ensure the species is based on a complete adult earthworm.
Description of Lectotype
Dimensions: body length 161 mm. Body cylindrical in anterior part, quadrangular in transverse section behind clitellum. 201 segments. Body colour pale brown. Anus dorsal terminal. At posterior end dorsal surface considerably broader than the ventral. Clitellar wi on ventro-lateral part of clitellum in 27–33. Prostomium zygolobous. Dorsal pores absent. Clitellum annular in 14–39. Four pairs of setae per segment from 2, setal formula aa:ab:bc:cd:dd = 1.0:0.5:1.5:0.5:1.0 at segment 8. Female pores, male pores and spermathecal pores not visible. Gm laterally paired or asymmetrical on bc in 18–26 and 33, median unpaired on aa in 13–17.
Septa 5/6–8/9 thicker, 9/10–10/11 thick and 11/12 to the last segment thin. Gi small, globular within 8–9. Intestine enlarged from 15. Dorsal blood vessel anterior to 8. He in 8–11. Np distinguishable from segment 14 onwards. Sv in 9–12, with the pair in segment 12 larger than the others. Ov in 13. Testis in 10–11. Prostate and accessory glands absent. Sc in 13/14–16/17, four to six on each side per segment.
Variation
The body lengths of type and non-type material 90–265 mm. 125–322 segments. Wi in 25, 26, 27–½32, 32, ½33, 33, 35, 36, clitellum in 13, 14, 15, 16, 17, 18–35, 36, 37, 38, 39, 40, 41.
Remarks
See Table 1.
This specieswas known from India: Malabar Coast, Travancore, Coorg, Mysore, Calicut, Malapuram and Tiruvallur, Gadana River, and tributaries in the buffer zone of Kalakkad-Mundanthurai Tiger Reserve from a sub basin of the river in the southern Western Ghats, Bangalore, and Bhadravatha and along the edge of Bhavani River, northern parts of Tamil Nadu, and southern parts of Karnataka, India. Sandy banks of the Harangi, Madapur (Coorg), and of the Cauvery, Dubari forests, Fraserpett (Coorg).
