Holotype: Male ( RMCA): D. R. Congo, Lulua, Sandoa , X-1031, G.F. Overlaet.

Description

Male: Length of body 18 mm, of fore wing 14 mm.

Antennae with more than 74 (apex broken) flagellomeres. Height of clypeus:intertentorial distance:tentorio-ocular distance51.0:3.0:1.4. Width of face:width of head:height of eye51.0:2.5:1.4. Height of face:width of face51.0:1.2. Sculpture on face scarce punctuation with a little smooth oval area on top of clypeus. Clypeus rugulose. Frons not depressed, smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.0:1.2:2.6. Length of eye in dorsal view:distance of occiput and posterior margin of eye52.3:1.0.

Mesosoma approximately 1.7 times longer than maximally deep.

Fore wing: length of veins r:3-SR:SR151.0:2.2:2.5. Length of veins 2-SR:3-SR:rm51.0:2.7:1.3. Length of veins m-cu:2-M51.0:3.5. Length of veins 1-CU1:2- CU151.0:7.1. Shape of vein 1-SR+M weakly s- shaped. Swelling in vein 3-CU1 1.6 times thicker than the other part of the vein.

Legs: Length of fore femur:tibia:tarsus52.2:2.4:1.0. Fore basitarsus 5.5 times longer than deep. Length of hind femur:tibia:tarsus52.0:3.1:1.0. Hind basitarsus 5.8 times longer than deep.

First metasomal tergite 1.6 times longer than wide; raised median area smooth, with strigose posterior margin. Second tergite 1.5 times wider than long; medial area raised and strigose. Sublateral areas depressed longitudinally, sculpture on latero-posterior areas coriaceous to pustulate. Third tergite 1.5 times wider than long; with strigated transverse furrows on anterior and subposterior margins, raised median area medially strigated to laterally coriaceous, only antero-lateral areas smooth. Tergites four and five similar but with medial raised area coriaceous. Tergite six similar to four and five but with very small antero-lateral areas. Tergite seven smooth.

Orange-yellow except for the following which are black: dorsal side of the head and temples, occiput, apex of mandibles, metasomal tergite two postero-laterally, tergites three to six. Apical margin of tergite six and tergite seven whitish yellow. Forewings darkened with following hyaline areas: basally from veins 1-M and cu-a, band below pterostigma and oval area around vein r-m. Hind wings darkened postero-apically.

Etymology

Named after the first author’s friend, Arto Holappa.
