Distribution and biology

The specimen has previously been recorded by Amaral et al. (2019). It was collected using a Malaise trap near a small stream in Serra Furada State Park, Santa Catarina State, at 503 m a.s.l. The other records of this species are from the Atlantic forest of the Brazilian states of RJ and SP. Only the altitude from São Paulo was reported, as 603 m a.s.l. ( Lane 1953; Borkent 2008).
