The genus Amazondoryctes  was synonymized with Pioscelus  by Belokobylskij (2006). In the molecular analysis ( Wild et al. 2013) specimens identified as Amazondoryctes  emerged basally within Heterospilus  but no specimens identified as Pioscelus  were available for analysis. Thus, the exact placement of these two genera within the Heterospilini  is still in question.

Two species occur in Costa Rica, Pioscelus mesomphalus  Marsh and Pioscelus costaricensis  (Marsh), comb. n. Descriptions for each species can be found in Marsh 2002.
