Diagnosis

Similar to and closely related to Ophion longigena , but with the temple usually less buccate and the lower side of temple less strongly convex in lateral view. Face usually narrower below the antennal sockets, with the clypeus almost square and the first metasomal segment more elongate and in most known specimens with a distinct dorsal undulation. The metasoma is posteriorly entirely testaceous and the sclerotised section of first sternite ends distinctly posterior to the spiracle. The punctation of the face centrally and the clypeus is of almost the same intensity, while the face is more densely punctate than the clypeus in O. longigena . The mandibles in known specimens show no sign of wear as is common in O. longigena . Ophion paukkuneni is also reminiscent of Ophion crassicornis , but with the ovipositor sheath testaceous (black in O. crassicornis ), central flagellomeres more elongate, and with a lower number of flagellomeres. The species is also easily confused with the species around Ophion perkinsi Brock , but is usually larger in size, has a higher number of flagellomeres and the central flagellomeres more elongate.

Etymology

The species is named in honour of the Finnish hymenopterist Juho Paukkunen.

Description

Fore wing length 14–15 mm. Antenna in both sexes with 50–53 flagellomeres. First flagellomere 3.0–3.5 times as long as wide. Temple in female strongly buccate. Head in lateral view temple slightly shorter than compound eye ( Fig. 20B View Fig ). Head in dorsal view with distinct gap between lateral ocellus and eyes. Head in frontal view rounded (width/height measured from the apical margin of clypeus to the top of head = 1.15–1.20). Face in frontal view narrower than in O. longigena , with clypeus approximately as long as wide ( Fig. 20A View Fig ). Punctation on face scarce in relation to O. longigena , interstices between punctures usually equal to diameter of punctures. Malar space long, about 0.4–0.5 times as long as mandibular base. Mandibles with inner angles, unworn. Wing membrane clear. Ramellus distinct, reaching 0.3 times the width of the discosubmarginal cell. Radius sinuous. Mesopleuron usually weakly shagreened and densely punctate with small punctures, spaces between punctures about equal to their diameter. Pleurosternal angles almost in level with sternal angles, right angled or slightly acute but apically rounded. Scutellum with distinct lateral carinae at least in basal half. Propodeum distinctly punctate, often quite polished, with anterior and posterior transverse carina usually strong. Longitudinal carinae delimiting area superomedia often weak or absent. Central longitudinal carinae often distinct basally. Sclerotised part of first sternite ending distinctly posterior to spiracle. First tergite elongate with distinct dorsal undulation (as in Fig. 20F View Fig ). Hind trochantellus shorter than wide in dorsal view. Inner spur of hind tibia about as long as 0.5 times hind metatarsus. Male unknown.

Colour

Body testaceous. Head with inner and outer eye margins yellow. Mandibular teeth black. Ovipositor sheath testaceous, concolourous with posterior metasomal segments.

DNA barcode

The DNA barcode sequence of one Swedish specimens of Ophion paukkuneni Johansson sp. nov. is available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: ADF9569. Specimen code STI-NJBC: 64).

Ecology

The species is active during late July–August. Other than that, nothing is known about the ecology of this species.

Distribution in Sweden

Very rare in Central Sweden, seemingly having a more pronounced northern distribution than O. longigena .
