Diagnosis

Very similar and closely related to Ophion mocsaryi , but with occipital carina centrally rounded, straight or with a central depression and face below antennal socket shagreened, usually with denser and deeper punctures. Lateral carinae delimiting area superomedia often weaker or missing anteriorly and area superomedia narrower. In Swedish specimens the flagellomeres are also usually slightly stouter.

Etymology

This species has, together with Ophion brocki Johansson sp. nov., been confused with Ophion mocsaryi in collections.

Description

Fore wing length 12–13 mm. Antenna in both sexes with 53–59 flagellomeres. First flagellomere about 3.0 times as long as wide. Subbasal flagellomeres 1.4–1.5 times as long as wide ( Fig. 8N ). Central flagellomeres about 1.2–1.3 times as long as wide. Subapical flagellomeres approximately 1.5 times as long as wide. Head in female and male weakly buccate behind eye. Temple in lateral view 0.4–0.5 as long as compound eye. Lateral ocellus usually touching inner margin of compound eye. Occipital carina centrally rounded, straight or with central depression ( Fig. 7A ). Face below antennal socket shagreened with dense deep punctures ( Fig. 8I ). Malar space about 0.1 times as long as mandibular base in female and male. Mandibular gape right-angled, with internal angles. Wing membrane clear. Ramellus distinct, 0.3–0.5 times the width of the discosubmarginal cell. Radius sinuous, but often evenly curved in males. Nervellus broken distinctly below the middle. Mesopleuron weakly shagreened, distinctly punctate. Interstices between punctures about 1.0–2.0 times their diameter. Epicnemial carina, in antero-ventral view, with pleurosternal angles slightly anterior to sternal angles. Pleurosternal angles slightly acute ( Fig. 9B ). Scutellum without distinct lateral carinae in basal half. Structure of propodeum quite shiny and slightly rugose, basally and laterally with distinct punctures. Anterior transverse carina often absent laterally but frequently complete. Posterior transverse carina interrupted centrally and often weak laterally. Longitudinal carinae delimiting area superomedia weaker anteriorly, often dissolving against the shagreened or rugose background. Area superomedia slightly longer than wide. Hind trochantellus shorter than wide in dorsal view. Legs normal with hind femur 6.0–7.0 times as long as wide. Sclerotised part of first sternite ending level to spiracle (as in Fig. 6H ). Inner spur of hind tibia as long as 0.4 times metatarsus.

Colour

Body testaceous. Mandibular teeth black. Head with inner and outer eye margins broadly yellow. Ovipositor sheath black or dark brown, contrasting in colour with posterior metasomal segments.

DNA barcode

The DNA barcode sequences of 11 Swedish specimens of Ophion confusus Johansson sp. nov. are available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: ABV8262. Specimen codes: STI-NJBC: 43, 48, 50–51, 133, 185, 229, 233, 265, 296, 341).

Ecology

According to Brock (1982) O. mocsaryi s. lat. (most likely including O. confusus sp. nov.) has been reared from several species of Noctuidae . Several of these records probably refer to closely related species in the aggregate. One female in NHRS is reared from Agrochola lota (Clerck, 1759) which is also one of relatively few hosts listed by Brock. Ophion confusus Johansson sp. nov. seems to be most frequently collected in or near to semi-open forests. It is active mainly during May and June.

Distribution in Sweden

A quite common species in Southern Sweden, but rarer or absent in the Central and Northern parts of the country.

Remarks

According to BOLD the species also occurs in Britain, the Netherlands and Germany.
