Etymology. The specific epithet refers to the type locality, the municipality of Cariacica . Occurrence. Reserva Biológica de Duas Bocas (20°16'19.05"S, 40°28'42.53"W), Cariacica , Espírito Santo state, Brazil.

Diagnosis. This species may be distinguished by the combination of the following characters: (i) apical projection of the pseudepiphallic median lobe longer than wide and with curved end ( Fig. 4 C, F); (ii) ventral projection of the pseudepiphallic median lobe directed to the median portion of the genitalia ( Fig. 4 A, D); (iii) pseudepiphallic apical lobe with sub-straight posterior and anterior edges ( Fig. 4 B, E); (iv) pseudepiphallic sclerite without evident dorsal slit ( Fig. 4 B, E).
