The male genitalia are unique in having a greatly elongate sternite IX, with narrow V-shaped caudomedian cleft, and a Y-shaped aedeagus without ventral spicules and an abruptly tapered, sharply pointed apex. Female unknown. Etymology The specific name refers to the Latin name of Lebanon (Libanus), where the holotype was collected.

Tergite IX short, slender, with elongate cerci. Gonocoxite short, stout; gonostylus moderately long, nearly straight, slightly curved distally, apex tapered, with pointed tip. Parameres (Fig. 1I) fused, rod-like; basal arms short, broad, bifurcate with unequal-length prongs; distal portion slightly vasiform, with heavily sclerotized margins, apical ⅓ narrower, more lightly sclerotized, with rounded tip. Aedeagus (Fig. 1J) with bare ventral membrane; basal arms broad, heavily sclerotized; basal arch curved, extending ⅓ of total aedeagus length; distal portion short, margin heavily sclerotized, with sharply pointed apex. Female Unknown. Distribution Lebanon; known only from the type locality. Remarks The male antennal flagellum of this new species has an elongate flagellomere 10 and a bare aedeagus, characters typical of members of the subgenus Bezzia. This new species differs from all other Palearctic and Afrotropical members of the genus by its greatly elongate sternite IX, which extends to the midlength of the gonocoxites and covers their bases.Published as part of Alwin-Kownacka, Alicja, Szadziewski, Ryszard & Szwedo, Jacek, 2017, Predatory midges of the tribes Palpomyiini and Sphaeromiini (Diptera: Ceratopogonidae) from the Middle East, with keys and descriptions of new species, pp. 1-30 in European Journal of Taxonomy 318 on pages 4-6, DOI: 10.5852/ejt.2017.318, http://zenodo.org/record/382745

No full textCeratopogon azari Dominiak, Alwin & Giłka, 2014 Ceratopogon azari Dominiak, Alwin & Giłka, 2014: 138 (male, Lebanon). Diagnosis. Males differ from all other species of the genus by the following combination of characters: apicolateral processes of tergite IX elongate, each bearing two setae, parameres fused on proximal 1/3, aedeagus with seed-like medial prongs, lateral prongs lightly sclerotized with setose apices. Material examined. LEBANON, Anti-Lebanon Mts., Maaraboun village near Baalbek (in the locality named Sheaibe), N 33˚ 55.376 E 36˚15.490, altitude 1781 m, stream and helocrene, 3 males, 3 females, 5.V.2012, net, leg. P. Dominiak. Distribution. A montane species living in Anti-Lebanon Mountains. Discussion. Ceratopogon including 41 extant species (Borkent & Grogan 1995) is a relictual Boreal genus which has Holarctic distribution (Szadziewski 2008). The species C. azari extends the southernmost distribution for this genus in the Western Palaearctic.

Fourth tarsomere cordiform, bearing ventrally at apex a pair of hyaline sensilla. TR(I) 2.0–2.1. Mid leg. Coxa and trochanter darker than rest of leg. First tarsomere armed with two apical, two subbasal and three central spines, all more delicate than on fore leg. Second tarsomere with two apical spines, third and fourth tarsomeres each with one apical spine. Fourth tarsomere with pair of hyaline sensilla at apex. TR(II) 1.9. Hind leg. Coxa and trochanter darker than rest of leg. Femur swollen. Tibial comb with seven large setae. Tarsus slightly paler than tibia. Basitarsus bent, with one complete row of palisade setae, one apical and one subbasal spine present. TR(III) 1.9– 2.0. Abdomen. Dark brown. Genitalia (Figs 3 c-g). Sternite IX short, with indistinct caudal margin. Tergite IX with very long (134 µm), blunt, singular or bilobed apicolateral processes; each bearing one small seta (Figs 3c, g). Gonocoxite 0.33 mm long, broad, slightly expanded at middle, with distinct ventral and dorsal apodemes (Fig. 3c, d). Gonostylus 0.24 mm long, almost straight, with blunt apex. Parameres slightly S-shaped, strongly sclerotized; apex weakly pointed (Figs 3e, 4b, c). Aedeagus triangular with bicorned apex and distinct ribs on lateromedian surfaces; basal arch very low (Fig. 3f). Female. Unknown. Distribution. Israel and Lebanon. Material examined. Holotype: male. ISRAEL. Nahal Qumeran, 22.III.1993, leg. A. Freidberg [TAU]. Paratype: LEBANON. Jezzine, Pont Al Khalass, 7.IX.2013, 1 male, leg. A. Alwin [CEI UG]. Etymology. Specific epithet is derived from historical name of the area of presence of the species—the Levant. Discussion. The holotype from Israel is distinctly darker and bigger than the paratype from Lebanon, moreover the holotype has bilobed apicolateral processes while in Lebanese specimen apicolateral processes are single. We treat these differences as infraspecific variability as noted in Kolenohelea calcarata (Szadziewski 1992). This species is very similar to Kolenohelea calcarata Goetghebuer, 1920 from the Palaearctic and K. leonina de Meillon & Wirth, 1987 and K. dycei de Meillon & Wirth, 1981 from the Afrotropical Region. Parameres in K. calcarata are almost straight to slightly C-shaped with flat sharp tips (Fig. 4a), while in K. levantica parameres are more stout and S-shaped, and their tips are cylindrical and more blunt (Figs 4b, c). K. leonina and K. dycei have S-shaped parameres and aedeagus with bilobed apex like in K. levantica. However, both African species have more slender parameres, especially at the base, and gonostyli armed with distinct apical teeth.Published as part of Alwin-Kownacka, Alicja, Szadziewski, Ryszard & Szwedo, Jacek, 2016, Biting midges of the tribe Ceratopogonini (Diptera: Ceratopogonidae) from the Middle East, with keys and descriptions of new species, pp. 551-572 in Zootaxa 4079 (5) on pages 561-563, DOI: 10.11646/zootaxa.4079.5.3, http://zenodo.org/record/105087
