Key of Glycia from North and East Africa and the Arabian Peninsula

1 Head, pronotum and elytra unicoloured dull brown. ......... G. unicolor Chaudoir, 1848

– Head and pronotum testaceus red; elytra bicoloured: major part blue or brown with weak or strong bluish or violet lustre. ........................................................................... 2

2 Red colour of elytra at base 2.5 or more intervals wide. Elytra rather dull because of distinct microsculpture. Intervals nearly flat on disc. ................................................... 3

– Only first interval or even only inner part of this interval (dark) red, often vanished already in midlength of elytra ( Fig. 1 ). Intervals shiny and clearly convex. Striae distinctly punctured, much more than in following species. ........................ G. socotrana sp. nov.

3 Elytra dark blue to dark brownish blue, more shiny. Testaceous sutural band two-three intervals wide, substraight towards apex, only at scutellum and just before apex somewhat wider ( Fig. 2 ). Apex of median lobe of aedeagus short, as wide as long, ventral margin (in lateral view) weakly but evenly curved ( Fig. 5 ). ..................... G. spencei (Gistel, 1838)

– Elytra brownish violett blue to brownish blue, in general dark design much ligther. Testaceous sutural band near base at least five intervals wide, in fact never reaching basal border (there mostly dark red); narrowed to two or three intervals in elytral midlength, then straight for a while, afterwards gradually narrowed to apex ( Fig. 3 ). Elytra somewhat duller. Tip of median lobe much longer than wide, ventral margin of aedeagus almost straight, only weakly bent near apex ( Fig. 6 ). ............................. G. rufolimbata Maindron, 1905
