Kirejtshuk, A. G.: Notes on the systematics of the African Nitidulidae (Coleoptera)

Diagnosis - This new species and C. (M.) mimicus sp. n. in contrast to other African members of the subgenus Myothoraxaxe characterized by moderately convex pronotum with arcuate and narrowly explanate sides visible from above (not strongly convex and not subquadrangular pronotum with lateral margins invisible from above). This character reminds that in the Asian C. (M.) lewisi REITTER, 1884, C. (M.) pygidialis GROUVELLE, 1897 and C. (M.) signatus GROUVELLE, 1908, although other characters provide evidence that close relationship between the new African and mentioned Asian species is scarcely probable. C. (M.) joliveti sp. n. and C. (M.) mimicus sp. n. have an appearance partly similar to that of C. (M.) mycetophagus LESNE, 1938, comb, n., though both new species are characterized by paler and moderately pubescent body, more arcuate pronotal and elytral sides, expressed microreticulation on dorsum and underside, narrower tibiae and different genitalia of both sexes. C. (M.) joliveti sp. n. has genitalia in both sexes highly similar to those in C. (M.)fumatusBOHEMAN, 1851, C. (M.) congoensis sp. n. and partly similar to those in C. (M.) mutilatus ERICHSON, 1834, but both related new species, C. (M.

) joliveti sp. n. and C. (M.) mimicus sp. n. differ from the mentioned in the following characters: C. (M.) joliveti sp. n. and C. (M.) mimicus sp. n.: I) body more oval and less convex, with more arcuate, evenly (gently) sloping and explanate sides of pronotum and elytra (well visible from above); 2) elytra shorter than wide combined; 3) straight and parallel inner edges of lateral lobes of tegmen; 4) narrower and longer apex of gonocoxites of ovipositor. C. (M.) fumatus BOHEMAN, 1851, C. (M.) congoensis sp. n. and C. (M.) mutilatus: 1) body more or less parallel-sided and markedly more convex, with scarcely arcuate, steeply sloping and extremely narrowly explanate sides of pronotum and elytra (pronotal sides somewhat and elytral sides scarcely visible from above); 2) elytra usually as long as wide combined or slightly longer; 3) inner edges of lateral lobes of tegmen form a foramen at base with curved edges; 4) wider and shorter apex of gonocoxites of ovipositor. Furthermore, the two new species, in contrast to other mentioned species, are characterized by comparatively finer punctation of dorsum. C. (M.) joliveti sp. n. and C. (M.) mimicus sp. n. are well separated mostly by the structure of male genitalia. Besides it, C. (M.) joliveti sp. n. has: - body in general more slender with elytra nearly as long as combined width; - dorsum with punctures only slightly larger than eye facets and separated by 1-2 puncture diameters, with interspaces finely microreticulated or almost alutaceous; - prosternai process narrower than antennái club, narrowly rounded at apex, with punctures as large and dense as those on the remainder of prosternum, and interspaces distinctly microreticulated;
