Type material.
Holotype ♂ (MRAC 22772), Cameroon, Littoral Region, Sanaga Maritine Division, Mouanko, forest, 03°38'N, 009°46'E, 16.VIII.2017, leg. A.R. Nzoko Fiemapong and J.A. Yetchom Fonjo.
Paratypes: 2 ♂♂ (without gonopods)(MRAC 22773), 1 ♂ (SEM, MRAC 22774), same locality, together with holotype.
Diagnosis.
Differs from other species of the genus by 19 body segments (♂), the presence of a boletiform epicranial tubercle inside a depression (♂), coupled with each gonopodal coxa supplied with two unusually strong basal setae and the telopodites which are deeply sunken inside a large gonocoel and show only two, contiguous, little-exposed branches (ab, bb). The solenomere (sl) is long and finger-shaped (Figure 26).
Name.
To emphasize the type locality; noun in apposition.
Description.
Length of holotype and paratype ca. 3.5 mm (♂), width of midbody pro- and metazonae 0.2 and 0.35 mm (♂), respectively. Colouration in alcohol almost uniformly very light yellow brownish (Figure 29F).
All other characters as in H. zamakoe sp. n., except as follows.
Body with 19 segments (♂). Epicranial region with a boletiform tubercle at bottom of an excavation in front of an evident swelling (Figs 25B, H). Interantennal isthmus ca. 1.5 times as large as diameter of antennal socket. Antennae long and strongly clavate, reaching behind to segment 3 when stretched dorsally (♂). In length, antennomere 3 = 6> 5> 1 = 2 = 4 = 7. In width, collum <2-4 <head = 5-15; thereafter body gradually tapering towards telson. Tergal setae medium-sized to short, each ca. 1/5-1/3 as long as metatergum, mostly bacilliform, more rarely subclavate, all ribbed (Figs 25M, N). Paraterga medium-sized, set at ca. upper 1/3 of metazonae), mostly regularly declivous (Figs 25A, E–G, I, J). Caudal corner of paraterga always rounded, drawn increasingly back, but reaching beyond rear tergal margin only on segments 16 and 17 (Figs 25J, M).
Legs rather long and slender, ca. 1.3-1.4 times as long as midbody height (♂); tarsi in anterior body half with ventral brushes (Figure 25K).
Gonopodal coxa with two unusually strong setae at base, at fusion site of both coxae (Figs 26C, D). Telopodite (Figure 26) almost fully concealed inside a very large gonocoel, each with only two branches (ab, bb), both contiguous and only slightly exposed beyond coxa, followed by no lobe more basally. Branch ab a little longer and faintly subdivided into two, branch bb shorter and slightly curved at tip. Seminal groove short, moving onto a long finger-shaped solenomere (sl).
