Diagnosis
Chimarra fenoevo sp. nov. is closely related to C. forcellinii sp. nov. These two species are characterized by the curved dorsal branches of tergum X (Figs 4B, 5B). They differ by the shape of the inferior appendages: triangular in C. fenoevo sp. nov. (Fig. 4A), whereas L-shaped in C. forcellinii sp. nov. (Fig. 5A).
Etymology
The name is that of the nearest city to the type locality.
