Type material.
Holotype ♂ (MRAC 22769), Cameroon, Center Region, Awae, secondary forest, 03°06'N, 10°29'E, 27.III.2018, leg. A.R. Nzoko Fiemapong.
Paratypes: 1 ♂ (SEM, MRAC: 22770), 1 ♂ (incomplete, badly fragmented and without gonopods)(MRAC 22771), same locality, together with holotype.
Diagnosis.
Differs from other species of the genus by the presence of a particular epicranial tubercle with fine filaments on top (♂), of 19 body segments (♂), coupled with only one main branch (ab) on the gonopodal telopodite, this branch being very strongly exposed, very long, falcate and directed laterally, followed by a very small lobe (lo) more basally (Figs 23M, 24). No solenomere.
Name.
To emphasize the strongly falcate gonopodal branch ap; adjective in feminine gender.
Description.
Length of holotype ca. 3.5 mm (♂), width of midbody pro- and metazonae 0.25 and 0.4 mm (♂), respectively. Width of midbody pro- and metazonae of paratype 0.5 amd 0.7 mm, respectively. Coloration in alcohol light marbled red-brown, prozonae, le.g., and venter light grey-yellow (♂)(Figure 29E).
All other characters as in H. zamakoe sp. n., except as follows.
Body with 19 segments (♂). Epicranial region concave anteriorly in front of a clear swelling and bearing at bottom a conspicuous round tubercle supporting a tight group of numerous long filaments, these directed anteriorly (Figs 23D, L). Antennae relatively short and clavate, reaching behind to almost segment 3 when stretched dorsally (♂). In length, antennomere 3 = 6> 5> 2 = 4 = 7> 1. In width, collum <segment 3=4 <2 <head = 5-16; thereafter body gradually tapering towards telson. Tergal setae medium-sized to short, each ca. 1/4-1/3 as long as metatergum, bacilliform or subclavate, ribbed all along (Figs 23 A–C, G–K). Paraterga medium-sized, set at around upper 1/3 of metazonae (Figs 23 A–C, K), mostly 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 slightly reaching behind rear tergal margin only on segment 17 (Figs 23C, I).
Legs a little shorter (♂), slender, ca. 1.1-1.2 times as long as midbody height; in length, tarsus> femur> prefemur> coxa = postfemur = tibia.
Gonopodal telopodites (Figs 23M, 24) almost fully concealed inside a very large gonocoel, each with only one main branch (ab) very strongly exposed beyond coxa, being also unusually long, falcate and directed laterally, followed by a very small round lobe (lo) more basally. Seminal groove short, ending on a small squarish lobe without a solenomere.
