Monolepta naumanni sp. n. Description. Total length: 3.60-4.80 mm (mean: 4.23 mm; n = 10). Head. Yellow, some specimens with pale brownish ver- tex (Fig. 38b), labnun, mandibles, maxillary and labial palpi brown. Antennae yellow, usually only last anten- nomere brown, rarely last two to three antennomeres brown (Fig. 38c). Antennae long, antennomeres 4 to 10 slender, elongate. Length of antennomeres two to three 1.00-1.05 (mean: 1.01), length of antennomeres three to four 0.37-0.43 (mean: 0.39). Thorax. Prothorax entirely pale yellow. Pronotal width 1.10-1.45 mm (mean: 1.26 mm), pronotal length to width 0.58-0.61 (mean: 0.59), very finely and irregu- larly punctured. Anterior third of elytra black or dark brown, in 20 % of specimens examined reddish brown, middle pale brownish-yellow, each elytron with black (10 %; Fig. 38b). brown (70 %; Fig. 38c) or w ithout (20 %; Fig. 38a) subapical spot, this spot with reddish outer margins (Figs Figs 38b, c). Elytral length 2.80-3.50 mm (mean: 3.18 mm), maximal width of both elytra l.°0 2.50 mm (mean: 2.31 mm), maximal width of both elytra to length of elytron 0.71-0.75 (mean: 0.73). Scutellum yellow or yellowish-red. Meso- and metatho- rax and legs brownish-yellow, apex of femur, tibia and tarsi paler yellow. Abdomen. Brownish-yellow. Female genitalia. Spermatheca small, with small nodulus, slender middle part and long and slender cornu (Fig. 40). Dorsal part of bursa sclerites slender, w ith small spines (Fig. 41a). \enlral part slender, outer mar- gin finely serrate (Fig. 41b). Male genitalia. Apical part of median lobe narrow, conical towards apex, basal three quarter parallel-sided (Fig. 42). Tectum broad, conical (Fig. 42b). ventral groove of median lobe wide, strongly narrowed tow ards the orifice (Fig. 42c). Median endophallic spiculae slen- der, ventral spiculae strong, hook-like, lateral spiculae broad, short, plate-like medial 1\ \\ ith spur (Fig. 42b). Distribution. Known from wet tropical forests from eastern Congo and Rwanda to southern Uganda. West- ern Kenya (Kakamega Forest) and north-west Tanzania (Ukerewe Island in Lake Victoria; Fig. 17). Diagnosis. Monolepta naumanni sp. n. can be distin- guished from all other species of the Monolepta vincta- group b\ the elytral coloration where subapical elytral spots have red outer margins. A \ery similar coloration is found in some specimens of .U. cjnadrizonata Labois- siere, 1940. which occurs syntopeh with M. naumanni sp. n. at some locations, but is much larger (total length 5.50 6.40 mm), elytra are \ery slender, and genital characters of both sexes are \ ery different ; \\ \GNER Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
