Distribution and biology
The single specimen has previously been recorded in Amaral et al. (2019). It was collected via CDC trap in an area of Atlantic forest in Santa Catarina State, at an altitude of 424 m a.s.l. This species is otherwise known from Costa Rica, at altitudes ranging from 0 to 600 m a.s.l. (Borkent 2008).
Remarks
This female presents an unusually large number of anepimeral setae for the rotunda group, and those setae seem thicker than the ones present on other species. See Morphology remarks section for more details.
