Material examined

Lectotype, ♀, of Ophion scutellaris ( MZLU); syntype, ♂, of Ophion longicornis ( ZMHB); lectotype, ♀, of Ophion stigmaticus ( BMNH); 161 ♀♀, 54 ♂♂ ( Sweden); 2 ♀♀, 2 ♂♂ ( Estonia); 8 ♀♀, 11 ♂♂ ( Norway).

Diagnosis

Fore wing length 15–19 mm. Antenna in both sexes with 60–71 flagellomeres. First flagellomere 4.0–4.5 times as long as wide. Central flagellomeres 2.0 times as long as wide. Head in females narrowed behind eyes. Temples more buccate in males. Face in anterior view slightly narrower than in O. wuestneii . Malar space about 0.2 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. Pterostigma elongate, about 3.5 times as long as wide. Ramellus distinct, reaching about 0.3 times the width of the discosubmarginal cell ( Fig. 16A View Fig ). Radius sinuous. Mesopleuron polished and weakly punctate. Interstices between punctures about 1.5–2.0 times their diameter. Pleurosternal angles obtuse, well defined, obviously anterior to sternal angles. Scutellum with distinct lateral carinae (as in Fig. 6C View Fig ). Propodeum shagreened-coriaceous, often quite shiny with anterior transverse carina partly absent laterally. Posterior transverse carina often widely interrupted centrally. Area superomedia usually absent, only weakly indicated posteriorly ( Fig. 10A View Fig ). Hind trochantellus shorter than wide in dorsal view. Hind femur strongly elongate about 9.0 times as long as wide (as in Fig. 16C View Fig ). Sclerotised part of first sternite ending distinctly posterior to spiracle. Inner spur of hind tibia as long as 0.3 times metatarsus.

Colour

Body testaceous. Mesoscutum, especially in males frequently with three brownish longitudinal stripes. Head with inner and outer orbits yellow. Mandibular teeth black. Ovipositor sheath testaceous, concolourous with posterior metasomal segments.

DNA barcode

The DNA barcode sequences of four Swedish specimens of Ophion scutellaris are available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: AAW9169. Specimen codes: STI-NJBC: 126–129).

Ecology

Ophion scutellaris occurs in early spring, sometimes as early as late March, and is active to early June. It has been reared from Noctuidae larvae which overwinter in their larval stage ( Brock 1982).

Distribution in Sweden

A common species in Southern and Central Sweden.

Remarks

The series under the label “ Ophion scutellaris ” in the Thomson collection in the ZMLU contains at least four different Ophion species. Apart from the lectotype only one specimen belongs to O. scutellaris .
