Ophion sinuosus Johansson sp. nov. urn:lsid:zoobank.org:act: 569E4C1C-8FBF-42F4-863B-187E75B42691 Figs 18A‒D Holotype: IRAN: ♀, Khorasan Province, Shomali-Ghuchan-Chakane, dga/ Pahne, 1780 m. a. s., 11‒12 Jun. 2009, Mof. leg. (HMIM). Paratype: IRAN: 1♀, same data as holotype (HMIM). Type depositories: The holotype female stored in HMIM and the paratype female stored in NHRS Diagnosis: Similar to Ophion rostralis (as here defined and delimited), but with fewer flagellomeres, wider face in anterior view and different carination of the propodeum with the anterior transverse carina distinctly sinuate, the posterior transverse carina only present laterally and all trace of central and lateral longitudinal carinae missing. Etymology: The name refers to the sinuate anterior transverse carina of the propodeum. Description: Fore wing length 14‒15 mm. Body length 15‒16 mm.Antenna with 49‒50 flagellomeres. Temple in lateral view narrow, about 0.3‒0.4 × as long as compound eye in female (Fig. 18C). Lateral ocelli touching inner margin of compound eye. Face wide (Fig. 18D). Occipital carina centrally evenly rounded. Face below antennal sockets strongly polished with very weak and scattered punctures. Malar space about 0.2 × as long as mandibular base (fig. 18D). Mandibular gape acute, without internal angles. First flagellomere 3.5 × as long as wide. Central flagellomeres stout, about 1.3 × as long as wide. Apical flagellomeres approximately 1.3 × as long as wide. Mesoscutum strongly polished without any obvious puncture. Mesopleuron polished with punctures quite dense, but very weak. Epicnemial carina, in antero-ventral view, with pleurosternal angles weakly obtuse, distinctly anterior to sternal angles. Scutellum without lateral carinae. Propodeum strongly polished. Anterior transverse carina distinct and sinuate (Fig. 18B). Posterior transverse carina strong laterally, centrally widely interrupted. Longitudinal carinae absent. Sclerotised part of first sternite level to spiracle. Hind trochantellus shorter than wide in dorsal view. Hind femur quite stout, about 6.0‒7.0 × as long as wide. Inner spur of hind tibia short, about 0.3 × as long as hind metatarsus. Wing membrane clear. Ramellus absent or short, reaching 0.2‒0.3 the width of the discosubmarginal cell. Radius weakly sinuous in outer part, its inner part straight before junction with pterostigma. Nervellus broken slightly below the middle by the discoidella. Male unknown. Colouration: Body pale brownish, light compared to other Ophion species. Head and mesosoma with pale pattern reminiscent of the members of the Ophion parvulus aggregate. Mandibular teeth black. ovipositor sheath concolorous with posterior metasomal segments.
