description: Achrysocharoides Girault   
 Achrysocharoides Girault, 1913a:168. Type species Chrysocharis sarcophaga Girault, 1913b:99, by original designation.   
 Neoderostenus Girault, 1913a:144. Type species Neoderostenus australiensis Girault, 1913a:144, by original designation. Synonymized by Peck (1951:464).   
 Enaysma Delucchi, 1954:1. Type species Enaysma zwoelferi Delucchi, 1954, by original designation. Synonymized by Yoshimoto (1977:907).   
 Diagnosis. Frontal suture almost straight, in females often replaced by a transverse ridge; males with a more or less developed frontal cross-carina (i.e. with a carina just below toruli), especially well developed in males with a strongly transverse head; eyes usually densely pubescent; pronotal collar without or with a transverse carina; forewing with postmarginal vein about as long as stigmal vein; petiole short with posterior raised portion short, never longer than broad.   
 Identification. To separate Achrysocharoides from other Eulophidae genera the keys in the following publications can be used: Bouček (1988) (Australasia), Gibson et al. (1997) (Nearctic), Graham (1959) (Europe). The key to European genera has a partly outdated nomenclature, e.g. Achrysocharoides is there referred to as Enaysma — now a synonym under Achrysocharoides, but this is the only available key for Europe. To separate the species-groups of Achrysocharoides the key in Kamijo (1991) can be used, and in the same publication there are detailed diagnoses for each species-group — this is excluding the crassinervis - group which is diagnosed in Kamijo (1990b).   
 Species-groups. 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 (1980) 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. The two species described here belong to the gahani -group (A. robiniae and A. robinicolus) and the latreilleii -group (A. platanoidae) respectively.
