Hemisphaeroparia bamboutos sp. n. Figs 19, 20, 29C

Type material.

Holotype ♂ (MRAC 22762), Cameroon, West Region, Bamboutos Division, Babajou District, Mt Bamboutos, 5°41 ’5” N, 10°06 ’23” E, 2600 m a.s.l., forest, 03.III.2017, leg. A.R. Nzoko Fiemapong.

Paratypes: 1 ♂ (SEM, MRAC 22763), same locality, together with holotype; 4 ♀♀ (MRAC 22764), same locality, 17.X.2017, all leg. A.R. Nzoko Fiemapong.

Diagnosis.

Differs from other species of the genus by the presence of a large, round, epicranial bulge (♂), coupled with the gonopodal telopodites being only moderately exposed above a deep gonocoel, each telopodite with only two branches (ab, bb), contiguous and followed by a small rounded lobe (lo) more basally. Branch bb shorter, with a conspicuous distomesal tooth (t). Seminal groove short, ending on a short retrorse solenomere (sl) nearly level with bb tip.

Name.

To emphasize the type locality; noun in apposition.

Description.

Length of holotype ca. 4.5 mm (♂), width of midbody pro- and metazonae 0.5 and 0.7 mm (♂), respectively. Length of ♀ paratypes 4-5 mm, width of midbody pro- and metazonae 0.4 -0.65 and 0.6-0.8 mm, respectively. Coloration in alcohol nearly pallid (♂, ♀)(Figure 29C).

All other characters as in H. zamakoe sp. n., except as follows.

Body with 19 segments (♂, ♀). Head with a large, round, densely micropilose, epicranial bulge (♂)(Figs 19A, D, G). Antennae long and clavate, reaching behind to segment 3 when stretched dorsally (♂, ♀). In length, antennomere 3 = 6 <2 = 5 <4 = 7 <1 (♂, ♀). In width, collum <3 <2 = 4 <head <5-15; thereafter body gradually tapering towards telson. Tergal setae slightly longer, each ca. 1/3-1/4 as long as metatergum, slightly clavate and bacilliform, ribbed and extremely delicately serrate (Figure 19K), setation pattern rather irregular per row: 2+2-4+4, 2+2-3+3 and 3+3-4+4 in rows 1-3, respectively. Caudal corner of paraterga always rounded, drawn increasingly back, but reaching beyond rear tergal margin only on segments 14-17 (Figs 19 A–F). Pleurosternal carinae a very delicately granulate line visible on all segments (Figure 19 A–C).

Legs rather long and slender, ca. 1.3-1.4 (♂) or 1.1-1.2 (♀) times as long as midbody height.

Gonopodal telopodites (Figure 20) only moderately exposed above a deep gonocoel, each with only two branches (ab, bb), both being contiguous and followed by a small rounded lobe (lo) more basally. Branch bb shorter, with a conspicuous distomesal tooth (t). Seminal groove short, ending on a short retrorse solenomere (sl) nearly level with bb tip.
