Key to species of Elaeidobius
1. Prothorax on middle of disc without a fovea on either side of midline ( Fig. 5A View Fig ); 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 View Fig ), followed by a distinct indentation. In male, prosternum between coxae generally with prominent process ( Figs 2A View Fig , 5B View Fig ) (subvittatus- group) .................................... 2
– Prothorax on middle of disc with a fovea on either side of midline ( Fig. 5C View Fig ); with a shallow depression on distal half on either side of a midline fold ( Fig. 5C View Fig ). Lateral carina of prothorax regular, not forming a constriction or indentation near collar ( Fig. 5C View Fig ). In male, prosternum between coxae without cuticular process (plagiatus- group) ........................................................................... 4
2. Rostrum distinctly longer than prothorax ( Fig. 2A View Fig ). In males, rostrum in lateral view on underside at apex smooth, without a tubercle or elevation ( Fig. 5D View Fig ). Elytra with dark markings on middle of interstriae 2–3, on each side of suture forming a central circular marking ( Fig. 5F View Fig ) ......................... ......................................................................................... E. bilineatus ( Hustache, 1924) comb. nov.
– Rostrum as long as prothorax in males, 1.2 × longer in females ( Fig. 2 View Fig B–C). In males, rostrum in lateral view on underside at apex with a protruding tubercle or cuticular elevation ( Fig. 5E View Fig ). Elytra yellowish brown or homogenously reddish brown lacking a central circular marking on disc ( Fig. 5 View Fig F–G) ....................................................................................................................................... 3
3. Body length under 2.3 mm. Pronotum and elytra yellowish brown with dark markings on prothorax and elytra ( Fig. 5G View Fig ). 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 View Fig ). 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 View Fig ) .................................... 5
– Elytra of male with long erect setae on margins and on suture ( Fig. 5I View Fig ) .......................................... 6
5. First two ventrites of male with deep median impression flanked by a fringe of semi-erect hairs ( Fig. 5 View Fig 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 View Fig ). 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 View Fig ). 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 View Fig 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 View Fig ). In male, row of erect setae along elytral suture forming a condensed spot near middle ( Fig. 5I View Fig ). Ventrites 1 and 2 in male lacking erect hairs on sides of median impression ........................................................................ E. kamerunicus ( Faust, 1898) comb. nov.
