Distribution and biology
The single specimen examined was previously recorded by
Ambrozio-Assis
et al.
(2018)
. It was collected via frog-call trap playing the call of
Boana bischoffi
, in
Santa Catarina State
, in an area of Atlantic forest, at an altitude of
470 m
a.s.l.
This species is otherwise known only from
Costa Rica
, at altitudes ranging from
1800 to 1850 m
a.s.l. (
Borkent 2008
).
