Description

Total length. 5.8–6.9 mm (mean 6.39).

Head. Labial and maxillary palpi, clypeus, and frons yellow to yellowish brown. Antennae yellow throughout ( Figure 39B View Figures 39–42 ), rarely antennomeres 4–11 annulate ( Figure 39A View Figures 39–42 ). Ratio length of second: third antennomere 0.51–0.61 (mean 0.56), ratio length of third: fourth antennomere 0.59–0.70 (mean 0.63).

Thorax. Underside of prothorax, meso- and metathorax black. Pronotum yellow, pronotal width 1.9–2.3 mm (mean 2.07 mm), ratio pronotal length: width 0.48–0.54 (mean 0.50). Elytral length 4.5–5.4 mm (mean 5.04 mm), elytra broad, maximal elytral width in the apical third of 2.9–3.7 mm (mean 3.25 mm), ratio maximal width of both elytra: elytral length 0.60–0.71 (mean 0.64). Scutellum and legs yellow, rarely scutellum brown. Males with deep, crater-like depression posterior to scutellum ( Figure 39A View Figures 39–42 ).

Abdomen. Yellow throughout.

Female genitalia. Spermathecae small, nodulus short and slender, nodulus usually small ( Figure 41 View Figures 39–42 ), bursa sclerites large with four strong spines ( Figure 40 View Figures 39–42 ).

Male genitalia. Median lobe parallel-sided, slightly dorsoventrally compressed, curved ( Figure 42B View Figures 39–42 ), apical third strongly narrowed ( Figure 42A View Figures 39–42 ). Tectum subapically broad, lanceolate, deeply incised ( Figure 42A View Figures 39–42 ). Endophallic spiculae of different size and shape, ventral part short and broad, nearly straight in dorsal view ( Figure 42A View Figures 39–42 ), dorsal pair shorter, strongly curved inwards ( Figure 42A, B View Figures 39–42 ). Orifice trapezoidal.

Distribution. Only 28 specimens could be found from Uganda, eastern Congo, and Sierra Leone ( Figure 19 View Figure 19 ). This disjunct distribution is presumably caused by rarity and the species is possibly also distributed in other countries of West and Central Africa.

Diagnosis. Sexual dimorphic pattern, the brown to black meso- and metathorax and shape of the median lobe of C. franzkrappi sp. nov. is most similar to C. irregularis indicating a close phylogenetical relationship between both species ( Figures 11A, 14 View Figures 11–14 , 39A, 42 View Figures 39–42 ). They differ in the coloration of hypomeron and prosternum (black in C. franzkrappi sp. nov., yellow in C. irregularis ), coloration of elytra (yellow throughout in C. franzkrappi sp. nov., with black spots in C. irregularis ), endophallic armature (cf. Figures 14 View Figures 11–14 , 42 View Figures 39–42 ), and shape and armature of the bursa sclerites (usually four spines in C. franzkrappi sp. nov., eight spines in C. irregularis ). Dorsal coloration most similar to C. flaveola , but easily distinguishable by the male sexual dimorphic and genitalic pattern of both sexes.

Derivatio nominis. Dedicated to Dr Franz Krapp, former curator at the Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn in honour of his humorous comments while this study was carried out.
