Type material.
Holotype male, slide-mounted: Brazil, Bahia, Barreiras, Rio de Janeiro, cachoeira Acaba Vidas, 11°53'40"S, 45°36'57"W, 722 m a.s.l., 14.x.2008, light trap, A.R. Calor, R. Mariano & S. Mateus leg. (UFSC).
Etymology.
The specific epithet is a noun in the genitive case honouring Rodolfo Mariano, for his friendship and prolific fieldwork.
Diagnostic characters.
The male can be distinguished from its congeners by the combination of: wing without dark markings; tergite IX without setose dorsal lobe(s) or thorns, with single, strong median seta, with narrowly triangular posterior margin and small, apical, parallel-sided anal point.
