Type locality. “Ephesus” ( Reitter 1885). This locality is an archaeological site in the northwestern Turkey on the Aegean coast, near Selçuk. The holotype label, “ Amasia /Ephesus”, is ambiguous but, in agreement with the original description ( Reitter 1885) and the specific name, we consider Ephesus as type locality.

Type specimens. As explained for C. prochaskana , we accept the unpublished selection of Reitter’s types, probably made by Kaszab, and we designate them lectotype and paralectotypes. The lectotype and one paralectotype from HNHM have been analysed :

Lectotype ♂: Amasia / Ephesus (white, handwritten) // Holotypus 1885 / Cerocoma / ephesica ♂ /Reitter (white with red frame, printed and handwritten) // LECTOTYPE ♂ / Cerocoma ephesica / Reitter, 1885 / Turco & Bologna des. 2009 (red, printed) ( HNHM). The specimen lacks left mesotarsal claws, right mesotarsomeres, and right last metatarsomere.

1 paralectotype ♀: Amasia (white, handwritten) // Allotypus 1885 / Cerocoma / ephesica ♀ / Reitter (white with red frame, printed and handwritten) // PARALECTOTYPE ♀ / Cerocoma ephesica / Reitter, 1885 / Turco & Bologna des. 2009 (red, printed) ( HNHM). The specimen lacks right maxillary palpomeres (except for the palpomere I) and antennae (except antennomeres I– II).

Description. Male. Body metallic green with a short yellowish pubescence, denser on pronotum; abdomen orange with last segment and apex of penultimate dark green metallic; antennae and mouthparts, including maxillary palpi, yellow-orange; fore legs yellow-orange; meso- and hind legs black.

Head sub-squared with protruding eyes. Maxillary palpi modified with palpomeres II–III wide, flattened and curved; IV stout (about 2x as long as wide), weakly flattened and gradually widened from base to apex ( Fig. 3C ). Antennae strongly modified with antennomere I bearing a short and pointed protrusion on the external side and dorsal keel narrow and very high, apically fringed; II–VIII variously expanded and shaped; IV with a narrow, long and curved expansion on dorsal side; V with a long and narrow expansion on dorsal side; IX very swollen and transverse ( Fig. 2C ).

Pronotum elongate with a long and deep medial line. Protibiae modified with a very high and flattened dorsal keel, apically curved ( Fig. 4C ). Protarsomeres dorso-ventrally flattened; I–IV widened on the external side; V distinctly angularly widened on the internal side.

Last abdominal sternite bearing two very long laminar expansions, about as long as the whole last abdominal segment. Gonostyli, in lateral view, slightly curved, with apical lobes dorsally directed, swollen and close to each other in dorsal view. Apex of aedeagus rounded; aedeagal hooks equal in size. Sclerotised hooks of endophallus small and distant from each other, equal in size, the apical pointing outwards and the subapical backwards ( Fig. 6C ).

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

Distribution. Macedonia, Bulgaria, Greece, European and Asiatic Turkey, Armenia, Azerbaijan, Iran. The old citation from Egypt ( Reitter 1913) was not confirmed and is particularly doubtful.
