Based on Archibald, Cover & Moreau, 2006

Almost all known specimens of this fossil genus are queens, with an exception of a single fossilised worker.

Baroni Urbani (2008) found that currently available specimens of this genus did not provide characters sufficient for placement to subfamily or even family and treated it as incertae sedis in Hymenoptera, while noting that overall morphological characters and wings show the specimens are undoubtedly a hymenopteran insect. However, Dlussky (2012) accepted the classification of Archibald and colleagues without mentioning the comments of Baroni Urbani (2008).
