Holotype: Portugal: 1♀, Porto, Gaia, 23 October 2004, G. Japoshvili (Institute of Zoology, Georgian Academy of Sciences ).

Description

Parts of the following description, notably colour and relative dimensions of the head, were made from the holotype before it was mounted on a slide.

Head and thorax very dark brown, almost black, with green metallic reflection. Gaster brown, only basal and apical parts slightly paler than centrally. Legs brown, only apical tibiae and first tarsal segment infuscate yellow. Antennal scape and pedicel also brown, remainder infuscate yellow. Forewings infuscate.

Scape slightly more then 7× as long as wide. Pedicel 2.5–2.6× as long as wide. First two flagellar segments almost 0.6× as long as pedicel. F3 1.5–1.6× as long as wide. Clava 2.8– 3× as long as F3, 3× as long as wide and 2× as long as scape. F5 about 3× as wide as head. Head about 1.25× as wide as high.

Pronotum with one long seta on each side. Mesoscutum covered by setae, and at the apex a pair of long setae. Axillae with a long seta on each side. Scutellum with three pairs of long setae. Forewings 2.6× as long as wide. Longest setae on the fore wing margin 1/18 as long as forewing. In front of linea calva five to six lines of setae varying from 60 to 64. Number of setae in costal cell: one to seven. Marginal vein almost 1.5× as long as submarginal. Hind wing about 4.4× as long as wide. Mid-tibial spur 0.7× as long as tarsal first segment on the longer side.

Exserted part of ovipositor no longer than three-quarters of mid-tibial spur. Gonostylus 0.4× as long as mid-tibia.

Relative measurements: DAO 8; DPO 5; EL 70; GL 43; GW 9; MS 37; MT 100; MTS 22; OOL 7; POL 32.

Diagnosis

The new species is most closely related to A. asychis , but differs by the following morphological characters: distal pronotum of the new species with one pair of long setae on each side; in A. asychis the pronotum bears three to five pairs of long setae on each side; hind femora of the new species are dark brown, while those of A. asychis are entirely yellow; clava of new species about 0.82× as long as scape, while clava of A. asychis 0.88× as long as scape.
