Figs. 1–11

Holotype: Turkey: Aksaray, Gözlükkuyu Village, elev. 1294 m, 0 1 July 2005, 1 male, Hasbenli leg. Paratypes: Turkey: Aksaray, Gözlükkuyu Village, elev. 1294 m, 0 1 July 2005, 1 male, 2 females, Hasbenli leg.

Diagnosis. Antennae relatively shorter than head. Legs black but knees and all tarsal segments yellow, last 3 tarsal segments darkened on external surface. Small yellow spots present at the edges of postpronotal calli. Medial process of genital capule with short, spine-like branches without membrane between them and genital capsule with prominent outer basal projection in lateral view. Female head black, with a pair of yellow frontal spots and elongate postocular yellow spots.

Description. Male ( Figs 1–3 ). Length: body 9.0 mm, wing 6.0 mm. Head black, almost hemispherical in lateral view. Eyes with dense brown hairs about 0.6 times as long as scape. Frons narrow, less than pedicel length, slightly divergent toward antennae. Frontal index about 3.8. Frons and face black. Postocular area swollen in lower half of head in lateral view, about 0.6 times as wide as scape length. Antennae relatively shorter than head, about 0.92 mm long and 0.52 times as long as head height, mainly black, slender, antennal index about 2.0. Basal segments mainly black, apical part of scape and pedicel brown. Scape about 1.6 times longer than pedicel: scape about 0.17 mm, pedicel about 0.13 mm. Flagellum consisting of 6 flagellomeres and about 0.62 mm long. Basal three flagellomeres thick, black and densely punctate. Last three flagellomeres conical. Basal half of 4th flagellomere and last two flagellomeres brownish. 4th flagellomere shorter than 3rd, about 0.65 times as long as 3rd. Last flagellomere spine like and slender, about 0.15 mm, at least longer than 2 preceding ones, about 0.86 times as long as scape and without hairs. Head pile as long as scape is long and fine, mostly erect, whitish. Proboscis short and stout.

Thorax black, punctate, only anterior half of anepisternum bare, shinning. Small yellow spots present at the edges of postpronotal calli. Postalar calli inconspicuously brownish. Thoracic pile whitish, mostly erect, fine, about two times longer than scape. Legs: coxa and femur black but knees and all tarsal segments yellow, last 3 tarsal segments darkened on external surface. Femur and tibia with long, erect, witish hairs. Wings slightly pale brownish infuscated, stronger veins yellowish brown. Halter pale yellow, with darkened stalk.

Abdomen black, with 3 pairs of narrow markings laterally on posterior margins of tergites 2–4, occupying about 1/4 their length, yellow lateral marking on tergite 4 proceeding inwards more than those on tergites 2–3. Posterior margin of tergite 5 also yellow. Inner end of each spot on tergite 2 almost rounded, those on tergites 3-4 slightly widened inwards and tapered towards tip. Venter black. Abdominal pile shorter than thoracic pile and mostly inconspicuous, adpressed, whitish dorsally and ventrally. Male terminalia: ( Figs 7–11 ): Epandrium shorter than that of L. krkensis and L. balius ( L. manni group) and also L. aktasii ; U-shaped, less swollen at sides than that in L. aktasii ; proctiger elongate-oval. Medial process of genital capule with short, spine-like branches without membrane between them and slender than that in L. aktasii , genital capsule with prominent outer basal projection in lateral view, its length almost equal to length of dorsal process of genital capsule in lateral view, slightly shorter than that in L. aktasii . Aedeagal complex long, sickle-like in lateral view, more bended in basal third than in L. aktasii , simple, almost paralel-sided, lateral parts separated almost to basal third of complex.

Female ( Figs 4–6 ). Length: body 9.0 mm, wing 6.0 mm. Head black, with a pair of yellow frontal spots and elongate postocular yellow spots. Frons occupying about 3/7 of head width. Eyes with inconspicuous, short, sparse dark hairs. Postocular band fairly broad, about as broad as basal antennal segments combined are long. Face slightly prominent in lateral view. Antennae mainly black as in male, but thickened in middle. Head pile silvery white, short and mostly adpressed, only long and erect ventraly. Proboscis darkened brown, short, stout.

Thorax as in male, with small yellow spots at edge of postpronotal calli. Postalar calli brownish. Thoracic pile short and adpressed, whitish grey. Legs and wings as in male. Halters pale yellow, with darkened stalk.

Abdomen as in male, with usual yellow lateral markings on tergites 2–4, posterior margin of tergite 5 also yellow. Yellow lateral markings on tegites 2–4 well separated along abdominal margin and more proceeding inwards on tergite 4 than on tergites 2–3. Venter completely black.

Etymology. The species is named after the type locality Aksaray Province from the Central Anatolian stepe in Turkey.
