Head subcubical; ocellar triangle with base larger than its sides; frons concave and with more or less distinct median keel; eyes glabrous; occipital carina entirely absent; postgenal bridge narrow; palpi formula 6-4; scape wide and short, without apical lobe; neck of promesosoma long more or less flat dorsally, with two long curved, acute and slightly depressed lateral processes, rarely with lateral tubercles only; pronotal keel absent; anterior mesonotum curving posteriorly and distinctly raised above pronotum; notauli present and smooth; sternaulus shallow, long and straight; prepectal carina distinct; postpectal carina absent; metapleuron often with dense silver pubescence; propodeum without marginate areas, areolate; lateral tubercles and propodeal bridge absent; fore tibia with sparse large spines arranged in single row; hind coxa small, without basoventral corner and tooth; all femora without dorsal protuberances; hind basitarsus 0.45-0.5 times as long as segments 2-5 combined; fore wing marginal cell shortened; 2RS and r-m present; 1m-cu distinctly antefurcal; 1cu-a postfurcal; 3CU arising from posterior 1/4-1/5 of apical side of first subdiscal cell; first subdiscal cell closed; hind wing with 4-5 hamuli; cu-a present; subbasal cell very large; m-cu absent; basal cell wide; RS arising from 1r-m near R; marginal cell without r; first metasomal tergite not petiolate, wide, with distinct dorsope; lateral side of first tergite obscured by long white hairs; acrosternite about 0.2x as long as first tergite; second suture deep, laterally strongly and sharply sinuate; second tergite with lateral wide subparallel furrows separating median area; ovipositor not longer than metasoma; apical part of ovipositor with 2 small dorsal nodes and serrate ventrally (modified from [1]).

The genus Acanthodoryctes differs to Antidoryctes (an other member of the Binariina tribe) by the third segment of labial palpi not shortened, frons not flattened, scapus without distinct apical lobe, marginal cell of fore wing shortened, hind wing without vein m-cu, pronotum with a pair of spine-like protuberances, and 1st metasomal tergite with modified setosity.
It is close to Liobracon with which it shares the following characters: occipital carina absent, head cuboid, pronotum with margins enclosing a deep transverse excavation, the converging carinae at junction of notauli, the hind coxa simple, the hind femora short and broad and the dense silvery hairs on side of thorax and propodeum. But it could be separated from Liobracon by the pronotal teeth, absence of a postnervulus and by the radiellan cell not being divided by a spurious vein [1]
