Eucymatodera strigata Gerstmeier, 2025, sp. nov.

Eucymatodera strigata sp. nov. (Figs 19, 26) Holotype ♂: RSA: Cape Province, Bontebok National Park, 14.– 16.11.1993, 34°04’ S / 20°27’ E, leg. J. Deckert (MFNB). Paratypes: RSA: Limpopo, Haenertsburg, Black Forest, 1500 m, 7.– 9.1.2014, leg. W. Schawaller (SMNS). Zoulouland, Dr Martin; 9/57, ex coll. R. Oberthür (MNHN). Ex Musaeo Thorey; Museum Paris, ex coll. R. Oberthur (MNHN) [no country information]. Cape Province: Somerset East. October 1930. S. Africa., R.E. Turner, Brit.Mus., 1930–561; B.M.N.H. pret no 3468 (BMNH). Diagnosis. Head almost smooth, anterior half with wrinkles. Antennae reaching beyond middle of pronotum, (when laid back), antennomeres dilated from A5 onwards. Elytral base margined in the middle, punctation with a basal seta. Prosternal length slightly smaller than procoxal diameter. AMP rectangular to trapezoid, front margin bulging. Gular pads large, mostly separated, sometimes adjoined. Description. Length: 10.1–15.0 mm. Head black, glossy, almost smooth, anterior half with very fine wrinkles; labrum and anterior part of clypeus black, smooth, glossy, with fine and diffuse punctation; palpi yellowish, terminal maxillary palpomere brown. Antennae brown, reaching beyond middle of pronotum but not quite reaching base (when laid back), antennomeres dilated from A5 onwards, not strongly (triangularly) dilated, more spherical, antennomeres longer than wide, A11 longer than A10, narrow, inner side subparallel, outer side only very slightly curved and slightly constricted at tip. EyW: 0.53–0.64 mm; EyD: 0.92–1.28 mm; EyD/EyW: 1.92. Pronotum red-brown to dark red-brown, glossy, base sometimes bordered black, mostly broadest in middle, sometimes before middle, constricted towards base and apex; with fine and diffuse (sometimes denser) punctation, in the middle sometimes wrinkled. PL: 2.64–3.72 mm; PW: 1.84–2.6 mm; PL/PW: 1.43. Elytra with shoulders and disc red-brown, humeri more-or-less black, behind the red part with a transverse, not sharply limited yellow transverse fascia, reaching the suture and mostly the side margin, behind the transverse fascia brown to black, subparallel, only slightly dilated towards apex; elytral base margined in the middle, punctation in 10 regular rows, rows 1 and 2 only reaching the beginning of the yellow transverse fascia or reaching the end or going through and beyond, rows 3–10 increasingly larger; punctation large, deep, becoming increasingly longitudinal, and smaller than interstices, apex with fine and diffuse punctation, no microsculpture, only small isolated punctures; elytral punctation with a basal seta. EL: 8.0– 10.25 mm; EW: 2.92–4.58 mm; EL/EW: 2.29. Legs more-or-less stout, red-brown to brown, if red-brown, tarsi darkened, tarsal soles lighter. Lower surface dark red-brown or predominantly black, prosternum in front and mesoventrite in the middle dark red-brown, abdomen light brown to dark red-brown, first ventrite with large, yellow maculae on sides. Gula red-brown, U-shaped, smooth, distal margins strongly bulging (and blackened), gular pads large, mostly separated, sometimes adjoined. Prosternal length slightly smaller than coxal diameter. AMP rectangular to trapezoid, front margin bulging, slightly dipped in front, posterior part smooth. Mesoventrite with large, irregular punctation. Metaventrite with fine, relatively dense punctation. Genitalia. See Fig. 26. Distribution: Only known from South Africa. Etymology. The specific epithet, strigatus, - a, -um, Latin adjective, refers to the striped punctation of elytra.
