The eronioides species-group

Diagnosis. The eronioides species-group can be distinguished from other species-groups by the combination of the following characters: 1) Larger than all the congeners. 2) Both wings generally darker than all the congeners especially the hindwing. 3) Hindwing bears an obscure postmedial band which largely merges with the darkened wings, while it is absent in all the congeners. 4) In male genitalia the distal end of saccular band gradually narrows and forms a long (ca. 1 × posterior tegumenal projection length) and strong horn-like process, while in the livida species-group the distal end of saccular band fuses with the distal sclerotized section of the costa and together form two dent-like processes and in the hyalina species-group the distal end of sacculus also fuses with the distal sclerotized section of the costa but together bear numerous smaller spines. 5) In female genitalia the basal plate of the apophysis anteriores bears a ventral band-like extension, while such extension is absent in both livida and hyalina species-groups. From the geoffi species-group the eronioides species-group can be easily distinguished by the presence of a pale spot in the cell R 4 on forewing, the 8th tergite with posterior end bifurcate and the simple juxta lobes.
