Figs 9, 10, 28D Type material. Holotype ♂ (MRAC 22748), Cameroon, Ongot Forest, 03°51'N , 011°25'E , ca. 810 m a.s.l., 26.III.2014, leg. A.R. Nzoko Fiemapong. Paratypes: 1 ♂ (SEM, MRAC 22749), same locality, 27.IX.2014, leg. A.R. Nzoko Fiemapong; 1 ♀ (MRAC 22750), same locality, together with holotype. Diagnosis. Differs from all other species of the genus by the presence of a boletiform epicranial tubercle (♂), coupled with the caudal corner of paraterga becoming increasingly strongly drawn behind the rear tergal margin starting with segment 13 and the gonopodal telopodites that are deeply sunken inside a large gonocoel and show three main branches (ab, mb, bb), all well-exposed and followed by no lobe, as well as a short solenomere with a tooth (t) at base of both sl and ab (Figure 10). Name. To emphasize the type locality; noun in apposition. Description. Length of holotype ca. 5.5 mm (♂), width of midbody pro- and metazonae 0.45 and 0.6 mm (♂), respectively. Length of paratypes (♀) 5.5 mm, width of midbody pro- and metazonae 0.55-0.7 mm (♂), respectively. Coloration in alcohol nearly pallid to very light yellow (Figure 28D). All other characters as in H. zamakoe sp. n., except as follows. Caudal corner of paraterga always rounded, drawn increasingly back, but reaching beyond rear tergal margin on segments 13-18 (Figure 9 A-C ). Gonopodal telopodite (Figure 10) deeply sunken inside a deep gonocoel, densely setose at base with three main branches (ab, mb, bb) mostly exposed: bb the shortest and rounded on top, mb slightly curved and subtruncate, and ab the longest and also slightly curved. Seminal groove relatively long, ending on a short solenomere (sl) supplied with an evident tooth (t) at base of sl and ab. Figure 9.
