DiagnosisOphion tenuicornis Johansson sp. nov. is one of the species in an aggregate previously treated under the name Ophion parvulus. Ophion tenuicornis Johansson sp. nov. is easily distinguished from the other species in the aggregate currently known from Sweden by the more elongate and strongly pilose flagellomeres, and from O. costatus and O. parvulus also by the considerably narrower temple in lateral view.
EtymologyThe species has very slender antennae.
Material examined> 100 ♀♀, 27 ♂♂ (Sweden); 3 ♀♀ (Germany); 1 ♀, 6 ♂♂ (Norway); 3 ♀♀ (Lithuania).

DescriptionFore wing length 15–16 mm. Antenna with 46–53 flagellomeres. First flagellomere 4.5 times as long as wide. Second flagellomere very elongate about 3.5–4.0 times as long as wide. Central flagellomeres elongate, about 2.5–3.0 times as long as wide. Apical flagellomeres approximately 2.5 times as long as wide (Fig. 8C). Apical flagellomeres in female, less so in males, with long prominent pilosity. Length of pilosity in females at least 0.5 width of flagellomere (Fig. 8C). Head narrow behind eyes, in lateral view with temple 0.2–0.3 times as long as compound eye in females, slightly longer in males, 0.4–0.5 times the lenght of the compound eye. Ocelli in female large, partly covering the inner margin of compound eye in dorsal view, the distance between ocelli about 0.3 times the diameter of ocelli. Malar space about 0.1 times as long as mandibular base in female and about 0.3 times in male. Mandibular gape right-angled, with internal angles. Wing membrane clear. Ramellus usually distinct, reaching 0.2–0.3 the width of discosubmarginal cell but sometimes small or absent. Radius evenly curved (Fig. 13A). Mesopleuron weakly shagreened with deep, distinct punctures. Interstices between punctures about equal to their diameter. Epicnemial carina, in antero-ventral view, with pleurosternal angles obviously anterior to sternal angles. Pleurosternal angles rounded, slightly obtuse. Scutellum with lateral carinae only indicated basally. Propodeum with very weak rugose structure, shining with anterior and posterior transverse carina strongly raised (Fig. 10L). Longitudinal carinae delimiting area superomedia and lateral longitudinal carinae sometimes weak or absent, but normally clearly indicated at the junction with the posterior transverse carina. Hind trochantellus shorter than wide in dorsal view. Legs normal with hind femur about 6.0–7.0 times as long as wide. Sclerotised part of first sternite ending level or slightly posterior to spiracle. Inner spur of hind tibia as long as 0.4 times metatarsus.
ColourBody testaceous. If infuscate or pale markings occur, they are usually far less distinct than in other species of the aggregate. Mandibular teeth black. Ovipositor brownish, slightly contrasting with the more testaceous posterior metasomal segments.
DNA barcodeThe DNA barcode sequences of nine Swedish specimens of Ophion tenuicornis Johansson sp. nov. are available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: ACK3000. Specimen codes: STI-NJBC: 243–248, 250–252).
EcologyThe flight period is late summer and autumn. One female in NHRS was reared from Thyatira batis (Linnaeus, 1758) and one female was reared from the same host in HSC. This is notable since only the two species of the subgenus of Platophion are known to parasitize the subfamily Thyatirinae. Both reared specimens are rather small, which suggests the existence of additional hosts.
Distribution in SwedenOccurs commonly all over the country, but rarer in the north.
