Sussaba erigator ( Fabricius 1793, Ichneumon )

Ichneumon festivus Fabricius 1798

Ophion festivator Fabricius 1804 (emendation for Ichneumon festivus Fabricius )

Diagnosis. Fore wing length 2.9–4.1 mm. Antenna in females with 14–15, very rarely 16 flagellomeres, with multiparous plate sensilla present also ventrally on apical flagellomeres, although slightly sparser there than dorsally, without conspicuous velvety areas; in males with 17–18 flagellomeres, with uni-coloured tyloids on flagellomeres 5 to 8 or rarely 9, first tyloid as large as or larger than second. Face mainly smooth and shining and strongly punctate over entire surface. Mesoscutum smooth and shining centrally, in females with punctures restricted to front part and sides, only very rarely with some sparse punctures in central area; in males, mesoscutum with punctures evenly distributed over entire surface. Mesopleuron smooth and shining, distinctly punctate over most of its surface. Hind coxa with outer hind surface mostly smooth and shining, without any sculpture apart from around seta roots. Propodeum with a full set of carinae enclosing basal, lateral and petiolar areas, the areas with rugose sculpture. Metasoma compressed posterior to third segment, usually not knife-like, first tergite 1.1–1.4 times longer than wide in both sexes.

Colouration of females. Antenna dark brown to black. Head and mesosoma black, face sometimes with a small yellow central face patch, clypeus black, yellow or orange on mouthparts, hind corner of pronotum, tegula, sometimes upper mesepimeron; subtegular ridge and scutellum black, without yellow shoulder marks. Legs orange, coxae black and trochanters black; femora orange, marked with black below; hind tibia and tarsus orange to brown. Metasoma variously marked with orange, usually at least on hind margin of tergite 2 and entire tergites 3 and sometimes 4; this colouration can be darkend, especially in high altitude or northern specimens.

Colouration of males. As in females but with yellow ventrally on entire antenna, entire face, often subtegular ridge. Fore and mid coxae with yellow apices, fore and mid trochanters often entirely yellow. Metasoma as in female.
