Etymology: The species epithet castilloae (feminine name in genitive case) refers to the Spanish hymenopterist Carmen Rey el Castillo.

Diagnosis: Ophion castilloae displays a combination of feature which, together with Ophion anatolicus sp. nov. makes it quite unique among European Ophion species. Most similar to Ophion anatolicus sp. nov., but with the face wider and a distinct gap between the lateral ocelli and the inner margin of the compound eye. The species is also similar to Ophion dispar Brauns ( Fig. 11D ), but have the face and mesosoma less densely punctate, the carination and sculpture of propodeum different, the spiracle of the first tergite closer to the sclerotized hind margin of the first sternite, the clypeus less wide and more scarcely punctate, the scutellum without lateral carinae, the ramellus absent (very long in O. dispar ) and the lateral ocelli further from the inner margin of the compound eye. Also similar to Ophion wuestneii Kriechbaumer , but with wider face, scutellum without lateral carinae, the lateral ocelli further from the inner margin of the compound eye and the carination of propodeum different. Due to the more reddish colour of the body also potentially confused with Ophion neglectus Habermehl , but never with the posterior metasomal segments infuscate.

Description: Fore wing length 10‒11 mm. Body length 15‒16 mm. Antenna with 51‒54 flagellomeres. Tem- ples buccate, in lateral view 0.7‒0.8 × as long as compound eye in female, 0.9 × in male ( Fig. 11C ). Space between compound eye and lateral ocellus wide, about 0.3 × the diameter of ocellus in female ( Fig. 11C ), 0.5 × in male. Face wide ( Fig. 11B ). Occipital carina centrally evenly rounded. Face below antennal sockets shagreened with distinct punctures. Malar space about 0.4 × as long as mandibular base in female and 0.6 × in males. Mandibular gape slightly acute, with internal angles. First flagellomere 4.0 × as long as wide. Central flagellomeres stout, about 1.4‒1.5 × as long as wide. Apical flagellomeres approximately 1.5 × as long as wide. Mesoscutum and mesopleu- ron shagreened with punctures quite dense, space between punctures about equal to their diameter. Epicnemial carina, in antero-ventral view, with pleurosternal angles strongly obtuse and indistinct, distinctly anterior to sternal angles. Scutellum without lateral carinae. Propodeum almost devoid of carination with very weak rugulose sculpture, opaque. Posterior transverse carina indicated laterally. Propodeum frequently with a small vertical central carina centrally, which joins a small u-shaped carina delimiting the posterior margin of the indicated superomedia, forming an y-shaped figure ( Fig. 11E ). Sclerotised part of first sternite ending distinctly posterior to spiracle ( Fig. 11F ). Hind trochantellus shorter than wide in dorsal view. Hind femur very slender, about 9.0 × as long as wide. Inner spur of hind tibia long, about 0.5 × as long as hind metatarsus. Wing membrane clear. Ramellus absent or short, reaching 0.4‒0.5 the width of the discosubmarginal cell. Radius weakly sinuous, distinctly bent before junction with pterostigma ( Fig. 11A ). Nervellus broken in the middle or slightly above the middle by the discoidella.

Colouration: Body red brownish, quite dark compared to other Ophion species ( Fig. 11A ). Inner and outer eye margins only slightly paler than face in female, more yellowish in male. Mandibular teeth black. Ovipositor sheath testaceous, concolorous with posterior metasomal segments.

DNA Barcode: The DNA barcode sequence of one specimen of Ophion castilloae sp. nov. is available at the BOLD systems database: sample id. NJP747, sequence id. LNU2583-21.
