Description

Female: Length of body 17 mm, of fore wing 14 mm, of ovipositor 18 mm.

Antennae with 107 flagellomeres, terminal flagellomere 2.6 times longer than wide. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:3.5:3.1. Width of face:width of head:height of eye51.1:2.1:1.0. Height of face:width of face51.0:1.7. Sculpture on face punctate with punctulation. Clypeus rugose. Frons depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.2:1.0:3.1. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.9:1.0.

Mesosoma approximately 1.9 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.6:3.9. Length of veins 2-SR:3-SR:rm51.0:2.0:1.1. Length of veins m-cu:2-M51.0:2.6. Length of veins 1-CU1:2- CU151.0:5.9. Shape of vein 1-SR+M weakly S-shaped, sometimes vein with uneven thickenings. Swelling in vein 3-CU1 1.5 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.1:2.4:1.0. Fore basitarsus 4.8 times longer than deep. Length of hind femur:tibia:tarsus52.1:3.1:1.0. Hind basitarsus 4.5 times longer than deep.

First metasomal tergite 1.7 times longer than wide; raised median area smooth, sometimes subposterior margin weakly strigose. Second tergite 1.5 times wider than long; antero-medial triangular area smooth and raised, and a ridge continuing from the apical end of the triangle towards posterior margin. Third tergite 1.7 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median and antero-lateral areas smooth. Tergites four and five with strigated transverse furrow on anterior and smooth transverse furrow on posterior margin, and with raised and smooth antero-lateral and median areas. Tergites six to eight smooth.

Yellow except for the following which are black: antenna, face, frons, vertex, apex of mandibles and ovipositor sheets. Wings darkened with hyaline areas in fore wing below pterostigma and in hind wing in the base of the marginal cell. Pterostigma apical half darkened.

Etymology

Named after the senior author’s friend, Suvi Ikonen.
