Type locality. Turkey, Prov. Urfa, Halfeti, valley of Euphrat, 500 m, 37°14.5'N, 37°52.5'E.

Diagnosis. This species is similar in morphology and coloration to D. mertliki sp. nov., but differs from the latter by the shape of pronotum (Figs 16, 19) and male genitalia (Figs 37, 41).

Description. Male (holotype). Body 3.4 times longer than width at humeri. Head black, elytra and ventral parts dark brown, pronotum and scutellum lighter, antennomeres 3–11 brown, mouthparts, scape, pedicel, legs and last abdominal ventrite yellowish brown; body covered with yellowish to light brown pubescence (Fig. 9). Head including eyes about as wide as anterior margin of pronotum (Fig. 19), dorsally with wide shallow depression, lateral margins above antennal sockets elevated, covered with large shallow punctures, with sparse semierect or erect pubescence; clypeal margin widely concave. Eyes medium-sized, their frontal distance 1.9 times eye diameter. Mandibles long, curved; incisor margin with short robust tooth in middle part. Labrum transverse; maxillary palpi slender, apical palpomere obliquely widely cut. Antennae pectinate, reaching one third of elytral length, antennomere 3 serrate, antennomeres 4–10 pectinate, apical antennomere simple, longest (Fig. 29). Pronotum slightly convex, transverse, widest at middle, 1.5 times wider posteriorly than length at midline. Anterior margin almost straight, lateral margins sinuate, posterior margin convex, bisinuate. Both anterior and posterior angles rectangular (Fig. 19); surface of disc sparsely punctured, with sparse erected setae, pubescence denser at angles. Prosternum transverse, slightly wrinkled, frontal margin almost straight, prosternal process minute, gradually declivitous. Mesoventrite v-shaped, anteromedially depressed. Elytra elongate, subparallel-sided, with longitudinal keel running from humeri toward apex, inconspicuous at apical 1/3 of elytra, slightly wrinkled, sparsely punctured, covered with semierect pubescence. Legs slender, slightly compressed, with sparse, long, semierect setae, tarsomeres 1–4 gradually shortened, tarsomere 4 shortest, apical tarsomere long, slender, slightly longer than combined lengths of tarsomeres 3 and 4. Aedeagus with robust, considerably curved phallus; paramera long; phallobase v-shaped (Fig. 41). Female and immature stages are unknown.
