Type material.
Holotype ♂ (MRAC 22754), Cameroon, Littoral Region, Sanaga Maritine Division, Mouanko, forest, 03°38'N, 009°46'E, leg. A.R. Nzoko Fiemapong and J.A. Yetchom Fonjo.
Paratypes: 4 ♂♂ (MRAC: 22755), 1 ♂ (SEM, MRAC 22756), 1 ♂ (ZMUM), 1 ♂ (UY1), same locality, together with holotype.
Diagnosis.
Differs from other species of the genus by having 19 body segments and by the absence of epicranial modifications in the ♂, coupled with the presence of only a single prominent branch (ab) which is exposed beyond the gonopodal coxa only distally; ab at the base with a large, lateral, finger-shaped process (lp); the seminal groove is rather long and moves onto a very short and retrose solenomere (sl) apically (Figure 14).
Name.
To emphasize the very small size; adjective in feminine gender.
Description.
Length of holotype ca. 3 mm (♂), width of midbody pro- and metazonae 0.25 and 0.3 mm, respectively. Length of paratypes 2.8-3.2 mm, width of midbody pro- and metazonae 0.2-025 and 0.3-0.4 mm, respectively (♂). Coloration in alcohol nearly pallid (Figure 28F), paratypes in places faintly pinkish.
All other characters as in H. zamakoe sp. n., except as follows.
Body with 19 (♂) segments. Head very densely micropilose, without epicranial modifications (♂)(Figure 13A, C, F, J). Interantennal isthmus ca. 1.5 times as large as diameter of antennal socket (Figure 13F). Antennae long and strongly clavate, reaching back to segment 3 when stretched dorsally (♂). In width, collum <segment 3 = 4 <2 <head = 5-16; thereafter body gradually tapering towards telson. Collum and most of postcollum metaterga with three transverse regular rows of setae, but some metaterga in anterior body half without middle row (Figure 13C, D, J, K). Tergal setae short, bacilliform to slightly subclavate, longitudinally finely ribbed (Figure 13 C–E, I-L). Paraterga always regularly declivous. Caudal corner of paraterga always rounded, never drawn back behind rear tergal margin (Figure 13 C–E, J–L).
Legs rather long and slender, ca. 1.2-1.3 times as long as midbody height; in length, tarsus> femur> prefemur> coxa = postfemur = tibia (Figure 13D).
Gonopodal telopodite (Figure 14) almost fully concealed inside a deep gonocoel, with only a single prominent branch (ab), this being exposed beyond coxa only distally; ab at base with a large lateral process (lp). Seminal groove rather long, moving onto a very short and retrose solenomere (sl) apically.
