Eviulisoma kirimeri sp. n. Fig. 7, Map 1

Type material.

Holotype ♂ (MRAC 22624), Kenya, Kirimeri Forest near Runyenyere, S00°25', E37°33', 1700 m a.s.l., sieved litter, 27.IV.2004, leg. D. VandenSpiegel, R. Jocqué & C. Warui.

Paratype: 1 ♂ (MRAC 22625), same data, together with holotype.

Name.

To emphasize the type locality, a noun in apposition.

Diagnosis.

Differs from congeners in the epiproct showing two distinct apical claws directed ventrad (Fig. 7b), as well as the gonopods being divergent, rather loose, with a complex, lamellar, apically unciform (u) solenophore (sph) partly sheathing a longer flagelliform solenomere (sl); postfemoral process (p) very simple, sickle-shaped (Fig. 7 C–F). See also Key below.

Description.

Length of ca 15-16 mm, width of midbody metazonae 1.5 (♂ holotype) or 1.7 mm (♂ paratype). Coloration entirely pallid.

Other adult characters as in Eviulisoma ngaia sp. n., except as follows.

Clypeolabral region rather sparsely setose (Fig. 7A). Stricture between pro- and metazonae very delicately striolate. Tegument generally smooth, often with only a few arcuate striae near and below ozopores. Pleurosternal carinae rather evident, arcuate ridges devoid of a caudal tooth, visible until segment 15 (♂). Epiproct (Fig. 7B) faintly concave between two evident, claw-shaped, apical papillae directed ventrad; subapical lateral papillae evident, rather well removed from tip. Hypoproct subtriangular, pointed between 1+1 submarginal setae borne on minute knobs.

Setose lobe between ♂ coxae 4 (Fig. 7C) roundly subtriangular. Sternite between ♂ coxae 5 flattened; sterna between ♂ coxae 6 and 7 unusually deeply excavate and ledge-shaped for accommodation of gonopod tips, the excavation’s frontal edge being densely setose (Fig. 7C). Postgonopodial sterna with small, but evident, almost sharp cones near each coxa, anterior pair being smaller than caudal one on each diplosegment. ♂ tarsi largely considerably longer than tibiae (Fig. 7C). Legs 1.2-1.3 times as long as body height (♂). All ♂ telopodite segments distal to coxa or prefemur with dense ventral brushes, but last leg-pair with ventral brushes retained only on tibiae and tarsi.

Gonopods (Fig. 7 C–F) rather loose, divergent, with a complex, lamellar, apically unciform (u) solenophore (sph) partly sheathing a longer and flagelliform solenomere (sl); postfemoral process (p) very simple, strong and sickle-shaped.
