The subdivision of Achrysocharoides was initiated by Graham (1959) who divided the European species into two subgenera, Enaysma Delucchi and Pentenaysma Graham. These correspond with the two species-groups, atys- and latreilleii-groups, which Bryan (1980a) introduced for the European species, thus abandoning the formal subdivision into subgenera. Yoshimoto (1977) divided the Nearctic species into two species-groups, the gahani- and guizoti-groups. Kamijo (1991) transferred some of the Nearctic species from the guizoti-group to either of the two newly erected clypeatus- and titiani-groups, and removed the remaining species in the guizoti-group to the latreilleii-group, thus terminating the guizoti-group. Kamijo (1990b) established the crassinervis-group for two species from Japan and one undescribed species from Nepal. Hence there are currently six species-groups in Achrysocharoides: atys-, clypeatus-, crassinervis-, gahani-, latreilleii-, and titiani-groups. See Kamijo (1991) for group-diagnostic characters.

Eyes densely pubescent (e.g. Fig. 3); females with frontal suture as a raised carina (i.e. with frons just above frontal suture protruding), straight (e.g. Fig. 3); males with frontal suture straight to slightly V-shaped, sometimes missing; females with antennal scrobes indistinct (i.e. not as narrow grooves) joining below frontal suture (e.g. Fig. 3); lateral downsloping part of pronotum with a longitudinal carina (Figs 60–63); postmarginal vein short, 0.5–1.5× as long as stigmal vein. Achrysocharoides is similar to Apleurotropis, but has a short postmarginal vein (in Apleurotropis postmarginal vein is 2.8–3.7× as long as the stigmal vein), with antennal scrobes in female joining below frontal suture (antennal scrobes join the frontal suture separately in Apleurotropis).

To separate Achrysocharoides from other Eulophidae genera the keys in Bouček (1988) (Australasia), Gibson et al. (1997) (Nearctic), Graham (1959) (Europe) are useful. To differentiate Achrysocharoides from other genera of Entedon- inae in tropical America the matrix key on the website http://www.neotropicaleulophidae.com can be used.
