Systematics: Subfamily DIASPIDINAE Tribe DIASPIDINI INCERTAE SEDIS (Normark, et al., 2019) Prodiaspis differs from Xanthophthalma in having numerous tubular ducts on both dorsal and ventral sides of abdominal segments, in having a valve-like sac at the aperture of the vulva, in the first instar larva having 6-segmented and non annulate antenna and having a trilocular disc pore accompanying the anterior spiracle (Young & Wang, 1984). Danzig (1993) considers Circodiaspis to be a junior synonym of Adiscodiaspis. Takagi et al. (1997) provide a taxonomic discussion of Prodiaspis and related genera.
