Meligethes (Chromogethes) amicus sp. n. (Figs 79-83) Specimens examined - Kenya: holotype, male (NRS) and 1 paratype (ZISP) - "Brit. O. Afr., Lönnberg", "13 Jan." Description of male (holotype) - Length 1.8, width 0.9, height 0.6 mm. Moderately convex dorsally and ventrally; dorsum dark blue grey to green, underside almost unicoloured black, but pronotal sides, antennae, mouth parts and legs reddish; dorsum nearly dull with a weak cooper shade, underside with a moderate shine; dorsum with dense, not long and feebly conspicuous yellowish grey hairs, 2.5-3.0 times as long as distance between their insertions; underside with thinner and longer pubescence. Head and pronotum with distinct (partly elongate) punctures, with diameter almost 1.5-2.0 times as big as that of eye facets, interspaces between them somewhat broader than halfa puncture diameter (on pronotal disc almost as large as a puncture diameter), with dense and regular, rather contrasting cellular microreticulation. Elytra with somewhat denser and more or less elongate punctures (partly fusing and forming irregular longitudinal rows) than on head and pronotum, but with very narrow interspaces between punctures somewhat smoothed. Metasternum, middle of prosternum and prosternai process with not quite distinct punctures, somewhat larger than eye facets, with interspaces between them markedly narrower than a puncture diameter and almost smooth. Pygidium, sides of prosternum and ventrites with very small, shallow and indistinct punctures, narrow interspaces between them with dense, cellullar and more or less contrasting microreticulation. Head slightly longer than distance between eyes, its anterior edge narrowly bordered, subtruncate and with almost distinct corners. Antennae about as long as head width, with club, comprising about 2/7 of total antennái length, antennomere 3 slightly longer than antennomere 2 and about 2.5 times longer than antennomere 4. Pronotum moderately convex, with subtruncate anterior and posterior edges, widely rounded anterior and posterior corners, widely arcuate sides, gently sloping to sides which are as widely explanate as width of antennomere 3. Elytra 1 and 1/5 as long as combined width (about 2 and 1/3 as long as pronotum), moderately steeply sloping at extremely narrowly explanate sides, somewhat subobliquc at apex, forming a small suturai corner and without traced suturai lines. Pygidium rounded at apex. Mentum subpentagonal and subparallclsidcd, about twice as wide as long. Last labial palpomere subcylindrical and more than twice as long as wide. Prosternai process somewhat convex along median part, arcuately widened before rounded posterior edge, widest part of it slignificantly wider than antenna! club, narrowly bordered at sides and apex. Distance between mesocoxae about twice and that between metacoxae nearly 4 times as great as that between procoxae. Metasternum shallowly depressed and without clear median line. Protibia subtriangular, about 1.5 times as wide as antennái club and finely crenulate along outer edge; meso- and metatibiae subtrapezoid, almost as wide as protibia; outer edge of meso- and metatibiae with dense row of moderately short and stout setae. Femora of usual shape, profemur about 1.5 times, meso- and metafemora about twice as wide as corresponding tibiae. Protarsus almost as wide as antennái club, but meso- and metatarsi about a third as wide as corresponding tibiae, claws simple and rather long. Aedeagus moderately sclerotized. Variability - The paratype is very similar to the holotype.
