Flint 1967: 3.

This is a very distinctive species with several interesting diagnostic characters. The character for which it is named, the lateral spine­like process on the apical section of tergum X, together with the overall shape of the apical section, is diagnostic. Other distinctive characters include the deeply bifurcate apex of sternum VIII, and the dense brush, rather than linear array, of setae on the posterior margin of tergum VIII.
