Diagnosis

Ageniella ruschi sp. nov. is unique among the species of Ageniella by having golden scale-like setae basally and above the clypeus and the wings darkened with the apex white; the integument is dark castaneous ( Fig. 3 View Fig ); and the clypeus is trapezoidal with the median apical margin polished and projected. The male of this species remains unknown.

Etymology

The species was named in honor of Augusto Ruschi (1915–1986), scientist, lawyer and teacher, known as the patron of ecology in Brazil, born in Santa Teresa, the type locality.

Distribution

Brazil (Espírito Santo).

Remarks

Ageniella ruschi sp. nov. is easily distinguished from other species of Ageniella distributed in Brazil by having the wing darkened with a whitish band on its apical fifth. Besides this unique wing pattern, the species has scale-like golden setae on the face and a frontal sulcus, only seen in few species of the genus.
