Prothorax on middle of disc without a fovea on either side of midline ( Fig. 5A ); without a shallow depression on distal half on either side of a midline fold. Lateral carina of prothorax forming a constriction near collar ( Fig. 5A ), followed by a distinct indentation. In male, prosternum between coxae generally with prominent process ( Figs 2A , 5B ) ( subvittatus- group) .................................... 2 – Prothorax on middle of disc with a fovea on either side of midline ( Fig. 5C ); with a shallow depression on distal half on either side of a midline fold ( Fig. 5C ). Lateral carina of prothorax regular, not forming a constriction or indentation near collar ( Fig. 5C ). In male, prosternum between coxae without cuticular process ( plagiatus- group) ........................................................................... 4 2. Rostrum distinctly longer than prothorax ( Fig. 2A ). In males, rostrum in lateral view on underside at apex smooth, without a tubercle or elevation ( Fig. 5D ). Elytra with dark markings on middle of interstriae 2–3, on each side of suture forming a central circular marking ( Fig. 5F ) ......................... ......................................................................................... E. bilineatus ( Hustache, 1924 ) comb. nov. – Rostrum as long as prothorax in males, 1.2 × longer in females ( Fig. 2 B–C). In males, rostrum in lateral view on underside at apex with a protruding tubercle or cuticular elevation ( Fig. 5E ). Elytra yellowish brown or homogenously reddish brown lacking a central circular marking on disc ( Fig. 5 F–G) ....................................................................................................................................... 3 3. Body length under 2.3 mm . Pronotum and elytra yellowish brown with dark markings on prothorax and elytra ( Fig. 5G ). In males, process between procoxae trilobate at apex (when present) ............. ................................................................................................................. E. s ubvittatus ( Faust, 1898 ) – Body length over 2.4 mm . Prothorax and elytra uniformly chestnut-brown, without contrasting darker markings ( Fig. 1B ). In males, process between procoxae rounded at apex (when present) .... ........................................................................................... E. spatulifer ( Marshall, 1950 ) comb. nov. 4. Elytra of male without long erect setae on margins and on suture ( Fig. 5H ) .................................... 5 – Elytra of male with long erect setae on margins and on suture ( Fig. 5I ) .......................................... 6 5. First two ventrites of male with deep median impression flanked by a fringe of semi-erect hairs ( Fig. 5 J–K). Elytra of male at base of interstria 4 flat, not raised to a swelling ................................. .............................................................................................. E. piliventris Haran & Kuschel sp. nov. – First two ventrites of male with shallow median depression and recumbent hairs only. Elytra of male at base of interstria 4 usually raised to a distinct swelling ... E. singularis ( Faust, 1898 ) comb. nov. 6. Elytra of male with long erect setae on tumescent base of interstria 4 ( Fig. 5L ). Apical half of protibiae of females widening apicad, as wide as apex of rostrum .................................................... ........................................................................................... E. plagiatus ( Fåhraeus, 1844 ) comb. nov. – Elytra of male lacking erect setae on tumescent base of interstria 4 ( Fig. 5I ). Apical half of protibiae of females distinctly narrower than rostrum width ........................................................................... 7 7. Elytra yellowish-brown with dark markings. In male, row of erect setae along elytral suture not forming a condensed spot near middle of length. Ventrites 1 and 2 of male with median impression flanked with semi-erect hairs ( Fig. 5 J–K) ............................. E. pilimargo Haran & Kuschel sp. nov. – Elytra dark brown, with one or two yellowish spots on either side of apical third, yellow often also on and around base of interstria 4 ( Fig. 5I ). In male, row of erect setae along elytral suture forming a condensed spot near middle ( Fig. 5I ). Ventrites 1 and 2 in male lacking erect hairs on sides of median impression ........................................................................ E. kamerunicus ( Faust, 1898 ) comb. nov.
