Type locality. “ Austria ” ( Gyllenhal 1817) .

Type specimens. The type of this species was not examined.

Description. Male. Body metallic dark green with short yellow pubescence; legs, antennae and mouthparts, including maxillary palpi, orange; frontal calli metallic green, except for the anteriormost internal margins orange; narrow orange spot in the area between frontal calli, wider posteriad.

Head transverse with slightly protruding eyes. Maxillary palpi ( Fig. 3R ) modified with palpomere II very wide, flattened and curved; III swollen and rounded on the external side; IV elongate and parallel-sided (about 2.5x as long as wide). Antennae modified ( Fig. 2R ) with antennomere I bearing a long, narrow and apically bent expansion on the external side and dorsal keel wide, high and curved at apex; III–VI very modified and ventrally expanded; V with a line of short setae on distal face of ventral laminar expansion; VI completely glabrous and with a very long, narrow and curved expansion on ventral side; IX slightly transverse, apically rounded, dorsally slightly flattened and dorsal edge weakly bilobate (posterior lobe particularly small).

Protibial keel short and straight in lateral view ( Fig. 4R ). Protarsomeres weakly dorso-ventrally flattened; II with an obvious dorsal bulge; protarsomere III shorter than V, excluding claws.

Gonostyli, in lateral view, straight, with apical lobes directed forward; apical lobes, in dorsal view, swollen and parallel. Apex of aedeagus pointed; aedeagal hooks equal in size. Sclerotised hooks of endophallus subequal in size (the apical larger), the apical pointing outwards and the subapical backwards ( Fig. 6R ).

Female. Not modified. Refer to key for diagnostic characters.

Taxonomy. Cerocoma muehlfeldi is very similar to C. turcica in some features, such as the low protibial dorsal keel and the maxillary palpomere IV very narrow and slender. On the other hand, the last four antennomeres are completely glabrous in C. muehlfeldi , whereas in C. turcica yellowish setae of variable length are present on at least antennomeres VI–VII.

Distribution. Austria, Hungary, Croatia, Serbia, Bosnia-Herzegovina, Montenegro, Albania, Macedonia, Bulgaria, Greece, Romania, S Ukraine, S Russia, Turkey, Syria, Israel-Palestine, Georgia, Armenia, Azerbaijan, Iraq, Iran, Turkmenistan. Records from Poland, Germany, Czech Republic and Slovakia need confirmation. Citations from Cyprus refer to C. azurea .
