Type material.

Holotype ♂ (MRAC 22739), Cameroon, West Region, Bangoulap, sacred forest (slightly disturbed), 6°00'N, 10°34'E, 13.X.2017, leg. A.R. Nzoko Fiemapong.

Paratypes. 2 ♂ (both without gonopods, either lost or mounted on slide)(MRAC 22740), 1 ♂ (SEM, MRAC 22741), same locality, together with holotype.

Diagnosis.

Differs from other species of the genus by the presence of a boletiform epicranial tubercle (♂), coupled with well-exposed gonopodal telopodites that show not only slender branches ab and bb, but each also a well-expressed lobe (lo) with an unusually deep transverse gutter (g) with very strongly thickened walls at the base, as well as a vestigial solenomere (sl) with a remarkable process (t) near its base (Figure 6).

Name.

To emphasize the type locality; noun in apposition.

Description.

Length of holotype ca. 6 mm (♂), width of midbody pro- and metazonae 0.5 and 0.7mm (♂), respectively. Length of paratypes 5.5-6 mm, width of midbody pro- and metazonae 0.5 and 0.7-0.75 mm (♂), respectively. Coloration in alcohol light pinkish to light pinkish brown, metaterga and antennae marbled red-brown. Prozonae, venter, and legs light yellowish grey (Figure 28B).

All other characters as in H. zamakoe sp. n., except as follows.

In width, collum <head <segment 3 <3 = 4 <5-16; thereafter, body gradually tapering towards telson.

Gonopodal telopodites more strongly exposed, less strongly setose, both main branches (ab, bb) longer, lobe (lo) also exposed, at base on lateral face with a prominent transverse gutter (g) with unusually strongly chitinized walls; branch bb sometimes subdivided into two flagelliform branchlets (Figure 6F, G). Seminal groove short, solenomere (sl) rudimentary, near its base with a conspicuous process (t).
