Type material.
Holotype male, slide-mounted: Brazil, São Paulo, São Sebastião, Rio das Pedras, 23°44'27"S, 45°37'12"W, 28.x.2005, light trap, A.R. Calor et al. leg. (UFSC).
Etymology.
The specific epithet is a noun in the genitive case honouring Lucas Silveira Lecci, for his friendship and prolific fieldwork.
Diagnostic characters.
The male can be separated from its congeners by its large size combined with unmarked wing; spatulate anal point; superior volsella leaf-shapped; inferior volsella with strong, split setae and digitiform and strongly setose gonostylus.
