Description.

Female.

Head entirely smooth; in dorsal view 1.8 times as wide as median length, 1.45 times as wide as mesoscutum, with convex rounded temples behind eye. Eye in lateral view 1.35 times as high as wide and 0.9 times as wide as temple medially. POL 0.8 times OD; OOL 2.8 times OD. Face smooth, with very fine reticulation, with sca ttered short setae in lateral areas, with low middle vertical protuberance, 2.1 times as wide as high; inner margins of eyes subparallel. Clypeus slightly convex ventrally, about twice as wide as high. Mandible broadened towards subapex, 0.9 times as long as its maximum width. Upper tooth of mandible broadened sideward, much longer than lower tooth; middle tooth wide basally and narrowed towards apex, rounded apically; lower tooth short, rounded apically. Antenna rather slender, 37-segmented. Scape 1.15 times as long as pedicel. First flagellar segment 3.1 times as long as its apical width; second segment 3.7 times as long as its maximum width, 1.2 times as long as first segment. Third flagellar segment about 3.0 times as long as its maximum width. Penultimate segment 2.2 times and apical segment 4.2 times as long as their maximum widths, respectively.

Mesosoma 1.5 times as long as high (lateral view). Mesoscutum smooth, punctate and densely setose in anterior part, 0.9 times as long as maximum width. Notauli coarsely crenulate, present in anterior half of mesoscutum, not reaching with mesoscutal pit. Mesoscutal pit present, very long, sparsely crenulate. Scutellar sulcus distinctly crenulate, with median carina but without lateral carinae. Sides of pronotum smooth in anterodorsal area, mainly rugose-reticulate. Precoxal suture present, wide, reaching anterior margin of mesopleuron but absent posteriorly. Posterior mesopleural furrow sparsely and widely crenulate below and shortly and densely crenulate in upper half. Propodeum completely rugose-reticulate, with numerous scattered setae. Propodeal spiracle relatively small.

Wings. Length of fore wing 2.3 times its maximum width. Pterostigma cuneate. Marginal cell distinctly shortened, reaching distinctly before apex of wing, 2.8 times as long as its maximum width. Vein 3-SR 1.7 times as long as vein 2-SR. Vein SR1 1.9 times as long as vein 3-SR. Second submarginal cell 3.3 times as long as maximum width. Vein cu-a distinctly postfurcal. Subdiscal cell closed, 2.3 times as long as its maximum width. Hind wing 4.0 times as long as its maximum width.

Legs. Hind femur 4.7 times as long as its maximum width. Hind tibia slightly widened towards apex, about 10.0 times as long as its maximum subapical width, as long as hind tarsus. First segment of hind tarsus 1.9 times as long as second segment.

Metasoma compressed laterally. First tergite completely and densely rugose-reticulate, without median carinae, slightly widened towards apex, 1.4 times as long as its apical width. Second metasomal tergite smooth. Ovipositor sheath 0.6 times as long as first tergite, 0.3 times as long as hind femur.

Colour. Body reddish brown to dark brown or black. Metasoma medially light reddish brown, apical segments dark brown. Legs mainly yellow, hind femur and tibia dark. Wings very faintly infuscate. Pterostigma brown.

Body length 3.2 mm; fore wing length 3.0 mm.

Variation. Body length 3.4 mm; fore wing length 3.3 mm. Mandible 0.8 times as long as its maximum width; middle teeth distinctly reduced. Antenna 39-segmented. First flagellar segment 3.3 times as long as its apical width; second segment 3.4 times as long as its maximum width, 1.1 times as long as first segment. Mesoscutum about as long as its maximum width. Length of fore wing 2.3 times its maximum width. Marginal cell 3.0 times as long as its maximum width. Vein 3-SR 1.55 times as long as vein 2-SR. Vein SR1 2.0 times as long as veins 3-SR. Second submarginal cell 3.4 times as long as its maximum width. Hind wing 4.3 times as long as its maximum width. Hind femur 5.3 times as long as its maximum width. First metasomal tergite 1.5 times as long as its apical width.

Male. Unknown.

Diagnosis.

This species is similar to Adelurola amplidens (Fischer, 1966) and Adelurola florimela (Haliday, 1838). Adelurola asiatica differs from Adelurola florimela by having the mandible 1.25 times as long as its maximum width (1.0 times in Adelurola florimela ), first metasomal tergite without median carinae (with median carinae in Adelurola florimela ), vein 3-SR 1.9 times as long as vein 2-SR (1.2 times in Adelurola florimela ), vein SR1 1.8 times as long as vein 3-SR (2.4 times in Adelurola florimela ), and precoxal suture reaching anterior and posterior margins of mesopleuron (not reaching anterior and posterior margins in Adelurola florimela ). Differences between Adelurola asiatica and Adelurola amplidens are in the re-description of the latter species.
