Type locality. “ Turkey, vil. Ankara, Gordion”. Gordion (Yassihöyük, in Turkish) was the capital of the Phrygian Kingdom during the eighth century BC. It is located about 100 km West of Ankara on the Sakarya River. This archaeological site includes a 16 meters high tumulus near which the types of Cerocoma longiseta were collected, together with specimens of C. turcica , on yellow inflorescence of Achillea sp. in a xeric continental steppe.

Diagnosis. A Cerocoma belonging to the subgenus Meloides as defined in the present paper, in particular to the C. adamovichiana , according to the shape and colour of male antennae, head capsule and fore legs (tibiae and tarsomeres), and close to C. albopilosa . It differs from all other species of this group by the combination of the following male characters: antennal setation yellowish, setae under antennomere VI very long, antennomere VIII pointed on one side; maxillary palpomere III in dorsal view very enlarged and rounded externally, IV triangular, evenly enlarged from base to apex; prothorax wide; protarsomeres short, about as long as protibiae, with the first two tarsomeres together longer than the remaining three, protarsomere III about as long as V, without claws.

Description. Body metallic green, paler on elytra, antennae (except female antennomere I, partly or wholly black), labial and maxillary palpi (female last maxillary palpomere sometimes partially infuscate), labrum, part of mandibles, frons and part of male frontal calli, legs (except coxae and trochanters, metallic) orange; frons of female with a very small and narrow orange spot, sometimes extremely vague. Body setation pale yellow, very long, dense, lanuginose. Body length: 10–13 mm.

Head distinctly transverse, without a depressed area over the eyes, frontal area between calli present (as in C. adamovichiana , see Fig. 5D ), frons convex in female, eyes slightly bulged, inner portion of frontal calli more or less extensively orange; templa very short, converging in male. Male antennae extremely modified as in Fig. 2I , setation yellowish; antennomere I bearing a long, narrow and slightly sinuate expansion on the external side and a dorsal keel very wide, high and apically curved; III–VIII more or less transverse and variously modified; V–VI each with a tuft of very long yellow setae; V with short setae on distal face of ventral laminar expansion; VI with a very long, narrow and distinctly curved expansion on ventral side; VIII pointed on one side; IX transverse, apically rounded, dorsally slightly flattened and dorsal edge bilobate (posterior lobe particularly pointed). Female antennae not modified, antennal club shorter than the preceding four antennomeres combined, last antennomere narrow at base, ovate. Male maxillary palpomere III in dorsal view very swollen and rounded externally, IV triangular, gradually widened from base to apex ( Fig. 3I ); female palpomeres slender.

Pronotum wide, almost parallel in the basal half and progressively curved anteriorly, in male with two deep and wide oblique dimples on the anterior half, with a narrow longitudinal middle furrow; in female sides widely rounded anteriorly. Male protibiae not depressed dorso-ventrally, in female the apical external angle only slightly pointed; protibial keel ( Fig. 4I ) high, progressively higher from base to apex, slightly curved anteriorly, without any angular prominence anteriorly; protibial spur pointed. Male protarsi short, about as long as protibiae, with the first two tarsomeres together longer than the remaining three, protarsomere II with an apical dorsal bulge, III about as long as V, without claws. Meso- and metatibiae and tarsomeres not modified in both sexes; metatibial spurs different in shape: external sub-spatuliform and obtuse at apex, internal narrow and pointed.

Last male abdominal sternite not modified, posterior margin V-emarginate. 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 small and very close to each other, equal in size, the apical pointing outwards and the subapical backwards ( Fig. 6I ).

Etymology. The name of this species refers to the long setae on antennomere VI, which discriminate it from C. albopilosa .

Taxonomic remarks. Cerocoma longiseta is very similar and closely related to C. albopilosa from which it can be recognised by the following characters: (a) yellowish setae below the antennomere VI distinctly longer; (b) antennomere VIII slightly pointed (rounded in C. albopilosa ); (c) maxillary palpomere III wider and more rounded. These two species show partially overlapping ranges with C. longiseta distributed from Bulgaria to the southeastern Turkey and C. albopilosa occurring in southeastern Turkey (Adana and Osmanyie provinces) and south Iran. These species are syntopic along the southeastern coast of Turkey.

Distribution. E Bulgaria, Turkey.
