Ophion anatolicus sp. nov.

Figs 9A–E urn:lsid:zoobank.org:act:938DF0E5-7ECB-4EFC-A5E2-94502DE2B28A

Holotype: TURKEY: ♀, 30 km N. Erdemli, Aslanli, 27 May 1998, Ma. Halada leg. ( OÖLM).

Etymology: The name anatolicus is derived from the region Anatolia in Turkey where the type specimen was collected.

Diagnosis: A very distinct species. Most simliar to O. castilloae sp. nov., which also has the radius strongly bent before the junction with the pterostigma, however with the face narrower and the ocelli touching the inner margin of the compound eye. Similar also to Ophion dispar Brauns , which has the radius straight before the junction with the pterostigma, and the spiracle of the first tergite further anterior of the sclerotized hind margin of the first sternite ( Fig. 11D ).

Description: Male unknown. Fore wing length 13 mm. Body length 15 mm. Antennae broken, the longest stump with 45 flagellomeres. Temple slightly buccate behind compound eyes, in lateral view about 0.6 × as long as compound eye ( Fig. 9C ). Malar space narrow, 0.1 × the width of the mandibular base. Space between compound eye and lateral ocellus narrow, about 0.1 × the diameter of ocellus ( Fig. 9C ). Face relatively wide ( Fig. 9E ). Occipital carina dorsally evenly curved. Face below antennal sockets distinctly and densely punctate, punctures often merging. Clypeus with large, deep but significantly scarcer punctures than the face, polished. Mandibular gape right angled, with internal angles. First flagellomere 3.5 × as long as wide. Central flagellomeres about 1.8 × as long as wide. Mesoscutum polished with very dense and distinct punctures, space between punctures at most equal to their diameter. Mesopleuron polished with very dense and distinct punctures. Epicnemial carina, in antero-ventral view, with pleurosternal angles obtuse, distinctly anterior to sternal angles ( Fig. 9D ). Scutellum without lateral carinae. Propodeum weakly rugulose with only the posterior transverse carina present, ventrally with a longitudinal shallow furrow ( Fig. 9B ). Sclerotised part of first sternite ending distinctly anterior to spiracle. Hind trochantellus shorter than wide in dorsal view. Hind femur slender, about 7.0 × as long as wide. Inner spur of hind tibia about 0.5 × as long as hind metatarsus. Wing membrane clear. Ramellus short, reaching 0.1–0.2 of the width of the discosubmarginal cell. Outer part of radius straight, weakly curved apically. Radius conspicuously bent and widened before junction with pterostigma ( Fig. 9A ). Nervellus broken slightly above the middle by the discoidella.

Colouration: Body yellow reddish. Inner and outer orbits narrowly yellow ( Figs 9A–E ). Mandibular teeth black. Remarks: A member of the O. ventricosus species group. DNA Barcode: The DNA barcode sequences of the holotype of Ophion anatolicus sp. nov. are available at the BOLD systems database: sample id. NJP737, sequence id. LNU2573-21.
