Type material.
Holotype ♂ (MRAC 22765), Cameroon, Center Region, Yaounde I University campus, palm plantation, 03°53'N, 011°30'E, 860 m a.s.l., 20.III.2018, leg. A.R. Nzoko Fiemapong.
Paratypes: 1 ♂ (SEM, MRAC 22766), 1 ♂ (without gonopods)(MRAC 22767), same locality, together with holotype; 4 ♂♂, 1 ♀ (MRAC 22768), 1 ♂ (ZMUM), 1 ♂ (UY1), same locality, 7.IV.2014, all leg. A.R. Nzoko Fiemapong.
Diagnosis.
Differs from other species of the genus by the presence of a boletiform epicranial tubercle (♂) and 19 segments in both sexes, coupled with the gonopodal telopodites (Figure 22) showing only one, but especially prominent and subfalcate main branch (ab), this being very strongly exposed beyond coxa; a long spiniform solenomere (sl) is subtransverse, directed forward and shows a short truncated tooth (t) at its base.
Name.
To emphasize the subfalcate gonopodal branch ab; adjective in feminine gender.
Description.
Length of holotype ca. 3.8 mm (♂), width of midbody pro- and metazonae 0.35 and 0.5 mm (♂), respectively. Length of ♂ paratypes 3-3.4 mm, width of midbody pro- and metazonae 0.25-0.35 and 0.5-0.7 mm, respectively; ♀ paratype 3.5 mm long, 0.25 and 0.4 mm wide on midbody pro- and metazonae, respectively. Coloration of holotype in alcohol light marbled brown; legs, head, and venter light brown-yellow. All paratypes lighter, light grey-brown to nearly pallid (Figure 29D).
All other characters as in H. zamakoe sp. n., except as follows.
Body with 19 segments (♂, ♀). In width, collum <3 = 4 <2 <head <segments 5-17; thereafter body gradually tapering towards telson. Caudolateral corner of collum acute and very norrowly rounded. Tergal setae medium-sized, bacilliform, usually a little longer, each 1/4-1/2 times as long as metatergum (Figs 21 D–F), always 3+3 in each row on postcollum metaterga. Paraterga medium-sized, set at ca. 1/3 of upper 1/3 of metazonae (Figs 21 A–C), visible starting with collum, mostly slightly declivous to subhorizontal often slightly upturned caudally, faintly, but regularly rounded and bordered, lateral incisions absent. Caudal corner of paraterga always rounded, drawn increasingly back, but reaching beyond rear tergal margin only on segments 16 and 17 (Figs 21C, F). Segment 2 with a very prominent, boletiform and apically complex spiracle on each side (Figs 21A, J, L).
Legs rather long and slender, ca. 1.3-1.4 (♂) or 1.1-1.2 (♀) times as long as midbody height. Sternum behind gonopods with a small central tubercle (Figure 22A).
Gonopodal telopodites (Figure 22) almost fully concealed inside a large gonocoel, each with only one main branch (ab), this being long, subfalcate, and very strongly exposed beyond coxa. Seminal groove short, at around midlength moving onto a long, spiniform solenomere (sl), the latter subtransverse, directed forward and showing a short truncated tooth (t) at base.
