Eucymatodera obliquefasciata sp. nov. (Figs 11, 24) Holotype ♂: Tanzania (Hbeya), Ujewa 8.– 9.1.1996, G. Curletti leg.; Ex larva, Acacia sp., N-1996 (MCCI). Paratype ♂: same label data (RGCM). Diagnosis. Head with diffuse punctation and fine wrinkles. Antennae reaching base of pronotum (when laid back), antennomeres dilated from A5 onwards, A8 wider than long. Elytral base margined, punctation with a basal seta, elytra with a typical, oblique, yellow-brown fascia. Prosternal length smaller than procoxal diameter. AMP rectangular to trapezoid; not conspicuously bulging. Gular pads large, slightly adjoined. Description. Length: 5.8–8.0 mm. Head dark brown to black, glossy, with diffuse (fine) punctation and fine wrinkles; labrum and palpi light brown to yellow, clypeus red-brown. Antennae reaching base of pronotum (when laid back), brown, antennomeres dilated from A5 onwards, A6 slightly longer than wide, A7 equal in length and width, A8 wider than long, A9 and A10 more-or-less equal in length, A11 shorter than A9+A10, broad, not very much constricted towards tip. EyW: 0.24–0.32 mm; EyD: 0.66–0.84 mm; WyD/EyW: 2.68. Pronotum slightly constricted in front, more constricted towards base, slightly sinuate before middle, dark brown, apex and base more-or-less reddish; anterior transverse depression in holotype not conspicuous, in paratype more conspicuous, in both cases with diffuse, fine punctation. PL: 1.56–2.0 mm; PW: 1.02–1.42 mm; PL/PW: 1.54. Elytra brown, glossy, shoulders light brown, in the middle of elytra with an oblique, yellow-brown fascia, reaching from outer margin to suture; elytral base margined. Punctation in 10 rows, almost reaching the apex, punctation deep and conspicuous, in humeral part diameter of punctation smaller than interstices, towards the yellow-brown fascia with increasing diameter (interstices smaller than diameter of punctation), behind the fascia diameter of punctation conspicuously smaller than interstices; punctation more longitudinal, with a basal seta. EL: 2.48–3.86 mm; EW: 1.14–1.64 mm; EL/EW: 2.26. Legs light brown to brown. Lower surface. Head and prothorax red-brown to black brown, meso- and metaventrite brown to dark red-brown, abdomen light red-brown, intersegmental sclerites yellow. Gula light brown, U-shaped, with a broadly bulging margin, with slight transverse wrinkles, gular pads large, slightly adjoined. Prosternal length smaller than procoxal diameter. AMP rectangular to trapezoid, margins not conspicuously bulging, almost smooth. Mesoventrite in the middle with deep and coarse punctation, sides smooth. Metaventrite almost smooth. Genitalia. See Fig. 24. Distribution: Only known from Tanzania. Etymology: The specific epithet, obliquefasciata, is composed from the Latin obliquus, - a, -um (= oblique), and fasciatus, - a; - um (= with fascia). It refers to the oblique yellow-brown fascia on the elytra.
