Description of Female. Fully winged; length 2.4–2.9 mm. Head of holotype testaceous-reddish, except occipital carina, ocellar triangle and three frontal longitudinal keels black; occasionally head testaceous-reddish, except frontal longitudinal keels and a stripe near ocelli black; occasionally head testaceous-reddish, except black frontal longitudinal keels and black median longitudinal keel present on clypeus. Antenna testaceous, except segments 6–10 brown. Mesosoma completely testaceous-reddish, occasionally with two brown spots on lateral regions of pronotum; dorsal sutures brown; dorsal surface and medial region of posterior surface of propodeum brown. Petiole testaceous. Metasoma brown. Legs testaceous, except clubs of femora partly brown and meso- and metatibia brown. Antenna clavate; antennal segments in following proportions: 8:5:5:4.5:4.5:4.5:4.5:4.5:4:7. Head shiny, punctate, unsculptured among punctures; face with three median longitudinal keels, including one complete frontal line; lateral longitudinal keels directed towards antennal toruli; face with many transverse folds located between longitudinal keels (folds stronger in anterior third of face); vertex behind ocellar triangle with two oblique keels connecting posterior ocelli to occipital carina; occipital carina complete; POL = 5; OL = 3; OOL = 5.5; OPL = 5; TL = 6.5. Thorax with a marked constriction between prothorax and mesothorax (Plate 56A). Pronotum shiny, smooth, finely punctate, unsculptured among punctures, with marked posterior constriction; disc flat and ovoidal (Plate 56A), surrounded by strong carina (carina black in holotype) (Plate 56B), with sparse long hairs; pronotal tubercle not reaching tegula. Scutum, scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctures, with sparse long hairs. Notauli incomplete, reaching approximately 0.2 length of scutum. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface shiny, smooth, unsculptured, without longitudinal keels. Fore wing with two dark transverse bands; distal part of stigmal vein much shorter than proximal part (2:5). Protarsal segments in following proportions: 4.5:2:4.5:8:18. Enlarged claw (Plate 56C) with one long bristle situated further distally than proximal prominence. Segment 5 of protarsus of holotype (Plate 56C) with two rows of approximately 33 lamellae; distal apex with approximately seven lamellae. In specimen from China, Taiwan, Taipei, segment 5 of protarsus with three rows of 2 + 22 + 4 lamellae (two shortest rows composed of longer lamellae). Tibial spurs 1/1/2.

Distribution. China (Taiwan), Thailand (Chiang Mai), Sri Lanka (Central Prov.).

Remarks. This species belongs to Deinodryinus because its enlarged claw has one long bristle situated further distally than proximal prominence (Plate 56C). It was described for mistake in the genus Anteon , whose species have one bristle located directly on the proximal prominence of the enlarged claw.
