Description of Phrosinella (Asiometopia) kocaki Verves & Khrokalo , sp. nov. ( Figures 1–6 )

Male: Body color: Bright colored. Head almost entirely densely silvery gray pollinated, frontal vitta black, finely dusted, scapus and pedicel brown, flagellomere and arista black, palpi yellow. Thorax densely light gray dusted, mesonotum with broad dark median longitudinal stripe before suture only. Legs black, fore tarsi brown. Wings hyaline, basicosta and epaulette yellow. Abdomen yellowish gray pollinated, in basal half yellowish brown laterally, with black dorsal drawing. 1+2nd tergite with narrow indistinct dark band or badly developed median spot and paired lateral stripes in hind 0.3; each of 3rd and 4th tergites in hind 0.4–0.5 with square or rounded three spots separated from one another by light dusting of narrow longitudinal bands; 5th tergite with similar drawing in hind 1/2–2/3. Genitalia shining black.

Body length: 6.5–8.5 mm.

Head: Frons at vertex 0.43–0.45×, at level of antennal base 0.47–0.50× of head width. Frontal vitta 1.2–1.5× widened backwards, at level of fore orb 0.8–0.9× as wide as one of parafrontalia. Flagellomere 3.7–4.5× as long as pedicel, arista widened in basal 0.8–0.9, bare. Parafacialia at level of antennal base 0.25–0.31×, genae 0.13–0.20× of eye height. Palpi elongate, at apex widened. Two regular rows of postorb; vte strong, 0.5× as long as vti; oc midlong; orb 1+2, strong; fr 9–14, beside them 4–5 fore pairs crossed, hind pairs reclinate; hind part of parafrontalia with several black erect long hairs; fore part of parafrontalia and parafacialia with microscopic yellow setae, almost bare; facial ridge above angular bristles with 2–3 black short setae; oral bristles numerous, their fore 2–3 pairs strong, others hair-like; genae and occiput with numerous yellow erect midlong setae ( Figures 1–3 ).

Thorax: Covered with densely black erect midlong hairs; acr 0+1, fine; dc 2–3+3, only prescutellar pair strong; ia 0–1+2–3, very fine; pprn 1–2; kepst 1+2, mid long; npl 2–3. Scutellum with 3 pairs of strong marginals (ap crossed), d less.

Legs: Each of 1st and 2nd tarsomeres of fore tarsi with elongate curved ad and pd, which reached to the end of 4th tarsomere, 3rd tarsomere with more short similar setae, 4th and 5th tarsomeres without long setae; t 2 with one ad ( Figure 4 ).

Wings: Costal spine small, badly developed, r 5 narrowly open, R 1 at upper side with 1–3 black hairs in basal half, R 4+5 dorsally with a row of setae in basal 0.5–0.7 of first section, ventrally with 2–3 basal hairs, M right-angled, dm-cu slightly s -like curved, almost straight, the ratio of 3rd and 5th costal sections is 1:1.5–2.3.

Abdomen: 1+2nd tergite without mediomarginals, 3rd tergite with a pair of erect long mediomarginals ( Figures 5 and 6 ).

Female: Related to male; fore tibia without specialized setae; median spot placed in hind 0.2–0.3 of length of 3rd abdominal tergite, and lateral stripes of this tergite narrow, partly reduced.

Etymology: The specific name is given in honor of one of the most known Turkish entomologists, Prof Emeritus Dr Ahmet Ömer Koçak, Van, Turkey.

Type material. Holotype (male): Israel: Sedom , 26.vi.1976, A. Freidberg leg. ( TAU) . Paratypes (males and females): Israel: Zin Wilderness , Nahal Zin at En Akrabim, cane-covered sandy wadi el. – 61 m, 30°53′38″N, 35°09′39″E [GPS], 12, 15, 23.iii. et 4.iv.1995, 3 ♂, 2 ♀ (Irwin) ( TAU & IEE) ; Negev , Ein Avdat National Park, Ein Aqev spring, 25.v.2006, 1 ♀ (K. Szpila) ( IEE) ; ‘ Enot Samar , 22.04.1998, 1 ♂ (A. Freidberg) ( TAU) .

Comparison: This species is related to P. (A.) kozlovi ( Rohdendorf, 1925) (Figures 7–11) by habitus, drawings of 3rd and 4th abdominal tergites and badly developed costal spine, but differs by ciliation of ♂ fore tarsi: bristles of 1st and 2nd tarsomeres very long, but 4th tarsomere without similar setae, and by three distinctly separated hind black spots at 5th abdominal tergite in both sexes.
