Material examined

Holotype: Female ( BMNH): Saudi Arabia, Wadi Majarish (below Taif), 12.2.1983, K. Guichard.

Description

Female: Length of body 17 mm, of fore wing 15 mm, of ovipositor 16 mm.

Antennae with 109 (apex broken) flagellomeres. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:4.2:3.2. Width of face:width of head:height of eye51.3:2.2:1.0. Height of face:width of face51.0:1.8. Sculpture on face pustulate. Clypeus granulate. Frons weakly depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.0:3.1. Length of eye in dorsal view:distance of occiput and posterior margin of eye51.5:1.0.

Mesosoma approximately 1.5 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:r-m5 1.0:2.2:1.3. Length of veins m-cu:2-M51.0:2.3. Length of veins 1-CU1:2-CU151.0:5.0. Shape of vein 1-SR+M apically straight and with a small convex area close to vein 1-M. Swelling in vein 3-CU1 1.5 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.3:2.5:1.0. Fore basitarsus 3.6 times longer than deep. Length of hind femur:tibia:tarsus52.0:3.0:1.0. Hind basitarsus 5.2 times longer than deep.

First metasomal tergite 1.5 times longer than wide; raised median area smooth with medial longitudinal depression and strigation on posterior margin. Second tergite 1.8 times wider than long; medial area raised and strigose. Antero-medial triangular area anteriorly more strongly raised, posterior part depressed and strigated. Third tergite 2.3 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area strongly strigated, antero-lateral areas smooth. Tergite four similar. Tergite five with strigated transverse furrows on anterior and posterior margins, median area raised and smooth, and smooth antero-lateral areas surrounded by similar furrows. Tergites six to eight smooth.

Yellow except for the following which are black: antenna, small area around stemmaticum, apex of mandibles and ovipositor sheets. Wings darkened with hyaline areas in fore wing in apical half of basal cell and below pterostigma, and in hind wing in the base on the marginal cell.

Etymology

Named after the senior author’s friend, Juha Markkola.
