Type locality. “Transcaucasia” ( Faldermann 1837).

Type specimens. The location of Faldermann’s types is uncertain. The material studied by this Russian entomologist was not examined for this study.

Description. Male. Body metallic dark blue or blue-green with short and sparse yellowish setae, black on the external side of meso- and metatibiae; abdomen orange with last segment and the posterior margin of penultimate (usually including the middle area) dark; antennae and mouthparts, including maxillary palpi, yellow-orange; legs black, except for protibiae and protarsomeres yellow-orange.

Head sub-squared with protruding eyes. Maxillary palpi modified with palpomeres II–III wide, flattened and slightly curved; IV long (about 2.5x as long as wide) and weakly flattened and sinuate on both sides ( Fig. 3E ). Antennae strongly modified with antennomere I bearing a narrow and very high dorsal keel apically fringed; II– VIII variously expanded and shaped; V with a very long and narrow expansion on dorsal side; IX very swollen and transverse ( Fig. 2E ).

Pronotum elongate. Protibiae modified with a very high and flattened dorsal keel, with apex only slightly curved and directed forward ( Fig. 4E ). Protarsomeres uniformly dorso-ventrally flattened.

Gonostyli, in lateral view, slightly curved, with apical lobes dorsally directed; apical lobes, in dorsal view, swollen and diverging. Apex of aedeagus rounded; aedeagal hooks equal in size. Sclerotised hooks of endophallus small and distant from each other, equal in size, both pointing backwards ( Fig. 6E ).

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

Distribution. Turkey, Armenia, Azerbaijan, Iraq, Iran, S Turkmenistan, S Kazakhstan, S Uzbekistan.
