Diagnosis

Most closely related and similar to Ophion perkinsi , from which it is distinguished by the more transverse head in anterior view, shorter malar space, the weaker microsculpture of the meso- and metapleuron and the stouter first tergite, usually lacking a median dorsal undulation. Also very similar to Ophion ellenae Johansson sp. nov. and Ophion matti Johansson sp. nov., from which it is separated by fewer flagellomeres, the more buccate temple, the head in dorsal view having a distinct gap between the eyes and lateral ocellus, the more distinctly punctate propodeum and the usually weaker carination of the propodeum. Also very similar to Ophion paukkuneni Johansson sp. nov., but with shorter flagellomeres, slightly less buccate temples and no dorsal undulation on the first tergite.

Etymology

Named after the son of the first author, Nore Nystedt.

Description

Fore wing length 12–13 mm. Antenna in both sexes with 48–50 flagellomeres. First flagellomere 3.0–3.5 times as long as wide. Central flagellomeres almost square to slightly longer than wide. Head buccate behind eyes, in dorsal view with distance between inner margin of compound eye and lateral ocellus 0.2–0.3 times diameter of ocellus. Head in anterior view strongly transverse ( Fig. 17D, F ). Temple in lateral view about 0.7–0.8 times as long as compound eye (as in Fig. 21D ). Malar space short, about 0.2 times the basal width of the mandible ( Fig. 17D, F ). Mandibular gape right-angled, with internal angles. Wing membrane clear. Ramellus distinct. Radius sinuous. Mesopleuron and metapleuron punctate with microsculpture weak or absent. Interstices between punctures about equal to their diameter. Pleurosternal angles rounded, often sharp, well defined and slightly anterior to sternal angles. Scutellum with distinct lateral carinae at least in basal half. Propodeum coriaceous and distinctly punctate. Anterior and transverse carina present centrally, often weak or absent laterally. Posterior transverse carina strongly raised, interrupted centrally. Longitudinal carinae delimiting area superomedia sometimes weak or absent (as in Fig. 10H ). Area superomedia usually as long as wide. Hind trochantellus shorter than wide in dorsal view. First tergite in lateral view rather stout without or with only a shallow dorsal undulation centrally ( Fig. 20E ). Sclerotised part of first sternite ending distinctly posterior to spiracle. Inner spur of hind tibia as long as 0.5 times metatarsus.

Colour

Body testaceous. Mandibular teeth black. Inner and outer orbits slightly yellowish. Ovipositor sheath testaceous.
