Diagnosis

The combination of the shape of the pleurosternal angles, the buccate temples and the number of flagellomeres separates this species from all other known Swedish species of Ophion . Ophion angularis Johansson & Cederberg sp. nov. is most likely to be confused with Ophion crassicornis Brock, 1982 and Ophion borealis Johansson sp. nov., but has more prominent pleurosternal angles, usually more numerous flagellomeres, slightly less buccate temples, entirely uncarinated scutellum and more densely punctate face.

Etymology

The pleurosternal angles are very prominent in this species.

Description

Fore wing length 15–17 mm. Antenna in both sexes with 59–67 flagellomeres. First flagellomere 2.5–3.0 times as long as wide. Central flagellomeres stout, about 1.2–1.3 times as long as wide. Apical flagellomeres approximately 1.5 times as long as wide. Temple in female and male strongly buccate, in lateral view 0.7–0.8 times as long as compound eye. Head with distinct gap between lateral ocellus and inner margin of compound eye. Face below antennal sockets very densely punctate, interstices about 0.2 times diameter of punctures. Malar space about 0.2 times as long as mandibular base in female and male. Mandibular gape right-angled, with internal angles. Wing membrane clear. Ramellus reaching 0.2–0.3 times the width of the discosubmarginal cell. Radius sinuous. Mesopleuron shagreened with very dense punctures which often merge centrally. Epicnemial carina, in antero-ventral view, with pleurosternal angles nearly in level with sternal angles, pleurosternal angles acute ( Fig. 9F View Fig ). Epicnemial carina between tip of pleurosternal angle and sternal part strongly concave. Scutellum without distinct lateral carinae in basal half. Propodeum distinctly punctate and coriaceous in front of anterior transverse carina, between transverse carina more often quite shiny, weakly rugose. Anterior transverse carina sometimes absent or weak laterally and posterior transverse often interrupted centrally, in continental specimens the anterior carina sometimes more strongly raised. Longitudinal carinae delimiting area superomedia and petiolar carinae often strong. Area superomedia quite narrow, about two times as long as wide. Hind trochantellus shorter than wide in dorsal view. Legs normal with hind femur about 7.0 times as long as wide. Sclerotised section of first sternite ending level to spiracle (as in Fig. 5H View Fig ). Inner spur of hind tibia 0.4 times as long as hind metatarsus.

Colour

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

DNA barcode

The DNA barcode sequences of four Swedish specimens of Ophion angularis Johansson & Cederberg sp. nov. are available at the BOLD systems database (www.boldsystems.org, BIN. BOLD:ADG2027. Specimen codes: STI-NJBC: 78–79, 186, 267).

Ecology

The species seems to occur in open or semi-open habitats and is active during late June–August. Other than that, nothing is known about the biology.

Distribution in Sweden

Rare but widespread in Southern Sweden.

Remarks

This species has been confused with Ophion crassicornis Brock, 1982 and was also probably partly included in the description of that species. Ophion angularis Cederberg & Johansson sp. nov. is, however, both morphologically and genetically distinct.
