Description of Female. Fully winged; length 1.9–2.9 mm. Head black, except mandible testaceous; antenna testaceous (in two specimens from China, Hainan, Mt. Yinggeling, antenna testaceous, except segment 10 and dorsal side of segments 2–3 and 6–9 brown); mesosoma black; metasoma brown; legs completely testaceous; occasionally metacoxa and meso- and club of metafemur partly brown; occasionally hindleg totally darkened. In two specimens from China, Hainan, Mt. Yinggeling, clypeus testaceous. Antenna clavate; antennal segments of holotype of A. borneanum in following proportions: 12:5:5:4:4:4:4:4:4:5; antennal segments of holotype of A. paraflaccum in following proportions: 12:5:6:4.5:4.5:4.5:4.5:5:5:8. Head dull, completely reticulate rugose, or granulated and with numerous irregular keels; frontal line complete; occasionally face with two lateral longitudinal keels near orbits; occipital carina complete; head of holotype of A. borneanum with POL = 5; OL = 3; OOL = 5; OPL = 3; TL = 3; head of holotype of A. paraflaccum with POL = 4.5; OL = 3; OOL = 4.5; OPL = 3; TL = 3. Pronotum shiny or dull, sculptured by numerous transverse keels; posterior surface of pronotum smooth, unsculptured, short, shorter than scutum (3: 14 in holotype of A. borneanum; 5: 13 in holotype of A. paraflaccum); pronotal tubercle reaching tegula. Scutum shiny or dull, granulated, laterally with irregular keels, occasionally with anterior margin smooth and unsculptured. Notauli incomplete, reaching approximately 0.3 length of scutum. Scutellum and metanotum shiny, smooth, unsculptured. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels. Fore wing hyaline, without dark transverse bands (as in holotype of A. borneanum) or with one dark transverse band (as in holotype of A. paraflaccum), or with one small dark spot situated beyond pterostigma; distal part of stigmal vein much shorter than proximal part (3: 7 in holotype of A. borneanum; 2.5: 7 in holotype of A. paraflaccum). Protarsal segments of holotype of A. borneanum in following proportions: 5:1.5:2:2:9; Protarsal segments of holotype of A. paraflaccum in following proportions: 7:2:2:2:9. Segment 4 of protarsus produced into hook. Enlarged claw ( Plate 20A, B ) with proximal prominence bearing one long bristle. Segment 5 of protarsus ( Plate 20A, B ) with basal part longer than distal part (7:2), with one–two rows of few bristles and 3–11 more or less slender lamellae extending continuously to distal apex. Tibial spurs 1/1/2.

Description of Male. Fully winged; length 1.6–3.0 mm. Head black, except mandible testaceous; antenna brown, except segments 1–2 testaceous; mesosoma and metasoma black; legs testaceous, except metacoxa partly darkened. Antenna filiform; antennal segments in following proportions: 9:3.5:3:4.5:4.5:5:4.5:4:4:7. Head dull, completely reticulate rugose; face with two lateral keels running along orbits towards antennal toruli; frontal line complete; POL = 4.5; OL = 2.5; OOL = 5; OPL = 2; TL = 2; occipital carina complete. Scutum shiny, granulated; occasionally scutum with posterior half granulated and anterior half punctate and unsculptured among punctures. Notauli incomplete, reaching approximately 0.4 length of scutum. Scutellum and metanotum shiny, smooth, unsculptured. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (2:7). Paramere ( Plate 20C ) shorter than penis, without distal inner process.
