Holotype: IRAN: ♀, Khorasan Province, Golulsara ni, 2800 m. a. s., 16‒17 Jul. 1997, Mirz./Ziai, ( HMIM).

Paratypes: IRAN: 1♀, Hormozgan province, Minab, Raveng , 27˚4’37.36"N, 57˚10’22.09"E, 34 m . a. s., 4 May 2016, Afsari / Mozh. leg. ( HMIM) ; 1♀, Ardebil Province, Azlandooz , 39˚26’15.1"N, 47˚24’05.9"E, 182 m . a. s., Mogh. / Nas. leg. ( HMIM) ; 1♂, Golestan Province, P. M. Golestan, 17‒18 Jul. 1996, 1650 m. a. s., Ebra. / V. Naz. leg. ( HMIM)

Type depositories: The holotype and paratypes is stored in HMIM, one female paratype is housed in NHRS.

Etymology: The name refers to the stout basal flagellomeres.

Diagnosis: Distinguished from other species of Ophion by the quite polished mesosoma with very scarce punctures, the carination of propodeum with complete carination, the anterior transverse carina conspicuously bent in front of the area superomedia and the stout flagellomeres.

Description: Fore wing length 13‒15 mm. Body length 16‒18 mm. Antenna with 49‒53 flagellomeres. Temple narrowed behind compound eyes, in lateral view about 0.3 × as long as compound eye in female ( Fig. 11D ), 0.5 × in male. Space between compound eye and lateral ocellus narrow, about 0.1 × the diameter of ocellus in female and male. Face narrow ( Fig. 11C ). Occipital carina centrally angulate. Face below antennal sockets polished, centrally with distinct punctures, which becomes weaker laterally. Malar space about 0.2 × as long as mandibular base in female and 0.3 × in males. Mandibular gape almost right angled, with internal angles. First flagellomere 3.0 × as long as wide ( Fig. 11E ). Central flagellomeres stout, about 1.2‒1.3 × as long as wide. Apical flagellomeres approximately 1.4 × as long as wide. Mesoscutum and mesopleuron polished with punctures quite distinct, space between punctures about 2.0 × their diameter. Epicnemial carina, in antero-ventral view, with pleurosternal angles strongly obtuse and indistinct, distinctly anterior to sternal angles. Scutellum with lateral carinae indicated in basal 0.2. Propodeum polished with very weak, rugulose sculpture. Carination complete. Anterior tranverse carina distinctly arcuate at upper part of area superomedia ( Fig. 11B ). Sclerotised part of first sternite ending posterior to spiracle. Hind trochantellus shorter than wide in dorsal view. Hind femur slender, about 8.0 × as long as wide. Inner spur of hind tibia quite short, about 0.3 × as long as hind metatarsus. Wing membrane clear. Ramellus reaching 0.3 of the width of the discosubmarginal cell. Radius weakly sinuous, straight before junction with pterostigma. Nervellus broken in the middle or slightly above the middle by the discoidella.

Colouration: Body yellow reddish, with the following paler whitish: inner and outer orbits, stemmaticum, four longitudinal stripes on mesoscutum (the central ones narrower), subalar prominence, speculum, a small spot in the lower posterior part of mesoscutum and one small spot corresponding on metapleuron, lateral margins of scutellum. Mandibular teeth black. Ovipositor sheath brown, slightly contrasting with posterior metasomal segments.
