( Figs 3 , 4 )

Material. Holotype (♂) and paratype (♀) ( ZDEU): Turkey, Diyarbakır Province, Hani District, Kuyular, 38°25’52.8492’’ N, 40°16’33.9888’’ E, 1.v.2011, leg. Inanç Özgen.

Description. Male. Body length 19.2 mm, width 7.2 mm. Body large, robust, black, with bluish tinge. Head. Anterior margin straight; lateral margin with weak wide emargination between frontoclypeus and genae; lateral margin of genae angulate, widely rounded; eyes strongly transverse, convex, head width 1.7× wider than interocular space; frontoclypeus with coarse and moderately dense punctation (puncture diameter 1.5× as long as interpunctural distance), punctures not connected; frons with coarser and denser punctation, punctures connected; vertex with very coarse and dense punctation, gula with coarse transverse wrinkles; mentum rectangular; last 4 antennomeres missing.

Prothorax. Pronotum transverse, 1.2× as wide as long, 1.58× as wide as head, widest a little behind middle; lateral margins rounded in anterior half, straight in basal half and undulate in middle; anterior margin widely emarginate, with small sinuation at middle; base trisinuate; anterior corners obtuse, widely rounded, weakly protruded; posterior corners weakly obtuse, narrowly rounded at apex; all margins beaded, but lateral and anterior margins with interrupted bead in middle; disc weakly convex, with widely, slightly flattened lateral sides; punctation of disc coarse, not dense, puncture diameter subequal to interpunctural distance; prothoracic hypomera with full thick bead, with coarse and dense smooth punctation; prosternal process beaded, cone-shaped, strongly projected.

Elytra widest at middle, elongate-oval, moderately convex, 1.73× as long as wide, 2× as wide as head, 1.28× as wide and 2.7× as long as pronotum; humeral callosities projected; dorsal epipleural carina narrow, but completely visible dorsally; strial punctures round, not connected; intestriae flat, smooth (without wrinkles), with fine and sparse distinct punctation (4, rarely 3 punctures in transverse section); each elytron with weak, widely rounded flat apex; epipleura with fine and sparse punctation.

Ventral side. Metaventrite with fine, moderately dense smooth punctation, punctures connect to wrinkles; abdominal ventrites 1–3 with coarse longitudinal wrinkles, without distinct punctation; ventrite 4 with wrinkles in basal part and fine smooth punctation in apical part; ventrite 5 with fine dense smooth punctation, completely and coarsely beaded.

Legs. Protibiae straight from extensor side and C-shaped curved from lateral side, with weak sinuation on inner side, not claviform; mesotibia weakly curved from extensor side and C-shaped curved from lateral side; metatibiae weakly curved from extensor side and straight from lateral side; all tibiae with very dense long brush of dark brown hairs on inner side; protarsi widened, protarsomeres 1–4 transverse, ratio of length/width of 1–5 protarsomeres: 1/1.3, 0.9/1.5, 0.7/1.4, 0.6/1, 2.9/1; mesotarsomeres weakly widened, mesotarsomeres 2–4 with subequal length and width, ratio of of length/width of 1–5 protarsomeres: 1.5/1.3, 1.2/1.2, 1/1.2, 0.9/0.9, 2.7/0.9.

Female. Body more large and robust. Body length 21 mm, width 9 mm. Pronotum more transverse, widest in middle, with protruded acute anterior corners, narrowly rounded at apex; posterior corners right; lateral margins in basal half weakly widely emarginate. Elytral interstriae 3–4 with 4–5 punctures in transverse section. Protibiae straight, meso- and metatibiae weakly curved from extensor side. Tarsi not widened.

Etymology. The name derives from Turkish “doğu” (eastern) and “ Anatolia ” (Asiatic part of Turkey).

Diagnosis. This species belongs to the subgenus Delonurops based on the non-beaded elytral apical suture (as in Eutelogonus ) and not strongly angulate lateral margins of pronotum (as the nominotypical subgenus). The new species differs from all known Delonurops by the flattened lateral sides of pronotum. It can be compared with E. clavimanus , E. bialookii and E. makovskyi , which also have strongly curved pro- and mesotibiae and widened pro- and mesotarsi. Entomogonus doguanatolicus sp. n. differs from all three species by the more robust male body with shorter elytra (elytra 2.5× as long as pronotum in a new species and 3× as long as pronotum in three listed species), wider male pronotum (1.26× as wide as long in E. doguanatolicus sp. n. and 1.08× as wide as long in E. bialookii and E. makovskyi ), non-claviform widened male protibia (claviform in E. clavimanus ), flattened apices of elytra (convex in E. bialookii and E. makovskyi ), protruding anterior corners (not protruding in E. bialookii and E. makovskyi ).
