Brachyodynerus kusdasi Gusenleitner, 1967

( Figs 21–23 )

Brachyodynerus kusdasi Gusenleitner, 1967: 670–671 , ♀ (type locality: “ Mut ” [ Turkey]).

Material examined. Julfa, 5 km N Dize , 39°03′N, 45°45′E, 965 m, 20. VI .2019, 1 ♂ [ CAFK] ; Julfa, Dize , 39°01′N, 45°45′E, 880 m, 20. VI .2019, 1 ♀ [ CAFK], 1 ♂ [ FSCV] .

Description of male (hitherto unknown). Body length (from head to apical margin of T2) 9 mm; fore wing length 6.5 mm.

Structure: Head approximately as wide as long in frontal view. Clypeus as wide as long; its apical emargination as deep as wide, taking 1/5 of clypeal width, lateral teeth acute. F11 very slender, its apex reaches posterior margin of F8. Vertex as long as upper portion of compound eye, more or less convex. Occipital carina strong laterally and indistinct dorsally. Anterior face of pronotum without median foveae; pronotal carina distinct, forming small but distinct acute angles at anterolateral corners of pronotum. Epicnemial carina distinctly developed and strong. Scutellum convex. Metanotum irregularly crenulated dorsally. Propodeal shelf not developed. Propodeal valvula bilamellate; upper lobe acute in lateral view. T1 1.7× as wide as long in dorsal view, rounded in lateral view. T2 strongly bent up at apex. S2 more or less uniformly convex in lateral view; basal longitudinal furrow on S2 obsolete.

Punctation: Clypeus finely and evenly punctured; interstices reach approximately 2 puncture diameters, shining. Frons, vertex, and temples with much denser and larger punctures than those on clypeus; puncture diameter reaches 1/2 diameter of lateral ocellus; interstices not reach puncture diameter. Anterior face of pronotum with punctures similar to those on frons, vertex, and temples but sparser. Dorsal and lateral parts of pronotum, scutum, mesepisterna, and scutellum with even more coarse and dense sculpture than that on frons, vertex, and temples; puncture diameter reaches 2/3 diameter of lateral ocellus. Tegula and parategula deeply punctured with medium-sized punctures similar in size to those on frons, vertex, and temples but much sparser; interstices reach approximately 2 puncture diameters, shining. Upper half of posterior face of metanotum with irregular sculpture of punctures with indistinct interstices; lower part smooth. Dorsolateral parts of propodeum with sculpture similar to that on pronotum, scutum, mesepisterna, and scutellum. Metapleura, lateral parts of propodeum, and propodeal concavity with similar but shallower, less distinct sculpture. Sculpture on basal yellow spots of T1 and T2 similar to that on pronotum, scutum, mesepisterna, and scutellum; punctures on black parts of these terga similar in size but elongated, with matt interstices reaching approximately 1/2 puncture diameter; apical yellow bands with smaller, rounded punctures and shining interstices similar to those on tegula. Punctures on T3–T6 much smaller than on apical bands of T1–T2, interstices reach approximately 2 puncture diameters, matt. T7 without distinct punctures. S2 coarsely punctured, puncture diameter reaches 2/3 diameter of lateral ocellus; interstices reach puncture diameter, shining. Punctures on S3–S7 much finer, about as those on corresponding terga; interstices matt.

Pilosity: Most parts of body almost bare. Mandibles, tibiae, and tarsi with unnoticeable straight short sparse pale setae, approximately as long as width of first labial palpomere at posterior end.

Color: Basically black. Following parts yellow: mandible except teeth, labrum, clypeus, large triangular spot on frons connected with clypeus, large spots along inner margins of eyes from clypeus to ocular sinuses, scape, large spots on temples at dorso-lateral corners of head, pronotum except central part of anterior face, dorsal and ventral mesepisterna, tegula and parategula, scutellum, metanotum, dorsolateral parts of propodeum, legs except hind trochanters and dorsal face of hind femora, large lateral spots on T1 and T2 connected with apical bands of these terga, apical bands on T3–T6, entire S2, apical bands on S3–S5. Pedicel, F1, F9–F11, and also ventral face of F2–F8 ferruginous. Wings fuscous, particularly on median, first submarginal, and marginal cells.

Distribution. * Azerbaijan, Turkey.

Remarks. This species is easily recognizable by its large size (in comparison with other representatives of the genus). The described males surely belonged to B. kusdasi because they were collected together with a female and, besides their size, had the same color pattern and punctation as the female had.
