Cerocoma prochaskana Reitter, 1896: 267 ; Reitter, 1913: 193; Mařan, 1944: 85.

Cerocoma (Cerocoma) prochaskana, Kaszab, 1951: 264 , 266, 272; Dvořák, 1989: 6, 10.

Type locality. “ Akbès, in Obersyrien” ( Reitter 1896). Akbèz is a village of SE Turkey, Hatay Province, along the eastern slope of the Amanus Mts., close to the Turkish-Syrian border.

Type specimens. Reitter’s collection is currently divided in two parts, preserved respectively in Budapest ( HNHM: general collection) and Paris ( MNHN: Chobaut’s collection). Two syntypes of C. prochaskana at HNHM have been labeled respectively as holotype ♂ and allotype ♀, probably subsequently by Dr Z. Kaszab, Director of the Budapest Museum and specialist of Meloidae when he worked on his revision of the genus ( Kaszab 1951), without publishing their designation. These specimens, together with the third male syntype ( MNHN) , have been examined. We accept Kaszab’s selection and we herein designate his holotype as lectotype and his allotype, together with the syntype in MNHN, as paralectotypes .

Lectotype ♂: Akbes (white, handwritten) // Holotypus 1896 / Cerocoma ♂ / Prochaskana / Reitter (white with red frame, printed and handwritten) // C. Prochaskana / m Akbes (white, handwritten, turned upside down) // LEC- TOTYPE ♂ / Cerocoma prochaskana / Reitter, 1896 / Turco & Bologna des. 2009 (red, printed) ( HNHM). Between the specimen and the first label there is a small (3 by 3 mm) white empty card. The specimen is badly damaged and head and prothorax are missing.

1 paralectotype ♀: Akbes (white, handwritten) // Allotypus 1896 / Cerocoma ♀ / Prochaskana / Reitter (white with red frame, printed and handwritten) // PARALECTOTYPE ♀ / Cerocoma prochaskana / Reitter, 1896 / Turco & Bologna des. 2009 (red, printed) ( HNHM). Protarsi and right metatarsus are slightly damaged .

Akesch. / ♂ (white, handwritten) // Cerocoma / Prochaskana / Reitter (white, handwritten) // MUSEUM PARIS / 1942 / COLL. D R. A.

Description. Male. Body metallic green with sparse and long yellowish setae; legs dark except for the protibiae, protarsomeres I–II and the apical half of pro- and mesofemora yellow; mouthparts black, except for the dorsal side of mandibles; antennae yellow, except for last four antennomeres and last maxillary palpomere dark.

Head transverse with protruding eyes and frontal calli raised over the head, bearing a tuft of yellowish setae on the external side. Maxillary palpi wide; palpomere II triangular; III expanded, flattened and curved; IV short and wide (about 1.5x as long as wide) with its base partially covered by the curved palpomere III ( Fig. 3T ). Antennae modified with antennomere I bearing a long and narrow dorsal keel, as well as a very narrow and long expansion on the external side; III–VI with long ventral expansions, those of III and IV pointed, V and VI rounded; IX transverse ( Fig. 2T ).

Protibiae slightly expanded dorsally in a short keel ( Fig. 4T ). Protarsomeres I–III dorso-ventrally flattened, IV–V subcylindrical.

Gonostyli, in lateral view, slightly curved, with apical lobes dorsally directed; apical lobes, in dorsal view, long, slightly swollen and distinctly diverging. Apex of aedeagus rounded; aedeagal hooks very long, thin and curved, subequal in size (the subapical slightly longer). Sclerotised hooks of endophallus equal in size, both pointing outwards ( Fig. 6T ).

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

Taxonomy. This species is clearly distinct from the others within the nominate subgenus in the antennomeres being visibly modified, as in C. schaefferi . It differs from this last species by the last four antennomeres being black, the last two protarsomeres very thin, and the legs mostly dark.

Distribution. SE Turkey, Syria, Israel-Palestine, Jordan, Iraq, S Iran.
