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 View Fig , 5B View Fig ). They differ by the shape of the inferior appendages: triangular in C. fenoevo sp. nov. ( Fig. 4A View Fig ), whereas L-shaped in C. forcellinii sp. nov. ( Fig. 5A View Fig ).

Etymology

The name is that of the nearest city to the type locality.
