Polydrepanum tamulum (sic!)— Jeekel, 1980b: 175, figs 16–19 (D).

Remarks. Being the type species of Polydrepanum, it shows only male femora 2 equipped with adenostyles (Fig. 16), while the gonopod demonstrates a twisted femorite and a complex solenophore (sph), the latter being divided into a small, subquadrate, lateral protecting lobe (lo) with two adjacent, curved, distofemoral processes (a and b), both latter forming a nearly complete dorsal ring and lying distal to the basal loop (k) of a free and subacuminate solenomere (sl). Base of lo on ventral side forming a protecting shield for the basal sl loop k. Distal half of solenophore strongly curved and directed dorsad (Figs 17–20).

Because P. tamilum shows a clearly twisted gonofemorite (Figs 17–20), vs. an untwisted one in P. asperrimum (Figs 3–5) or P. fissum (Figs 6–8), only two latter species can be considered congeneric and belonging to Grammorhabdus . In contrast, only four species, including both P. tamilum and P. horridum, appear to represent true named Polydrepanum, as further discussed below.
