Polydrepanum sp. nov.— Bano & Murthy, 1997: 161, fig. 11 (D). India, Karnataka.

Polydrepanum sp. 2 — Sankaran & Sebastian, 2018: 171, fig. 6E (D).

Remarks. An unnamed species from an unspecified locality in Karnataka state, India, the right gonopod of which has been presented in a crude sketch by Bano and Murthy (1997), reproduced here in Figs 23 and 24 . Because this species, likewise to be neglected, being unnamed and based on material of unknown provenance and whereabouts, seems to show an untwisted gonofemorite, a basal loop of the solenomere, and a distinctly coiled and slender distal half of the solenophore, it does resemble Grammorhabdus asperrimus or G. fissus (cf. Figs 3–5 , 6–8 and 23, 23 ) and thus may prove to be their potential congener.
