Revised diagnosis.
Males of
Atelurius segmentatus
can be identified by the finger-like RvTA totally covered with denticles (
Fig. 62
), hook-shaped, single-lobed RTA and by the lack of any apophysis of the tegulum. Females differ from those of
At. dipterioides
by the larger atrium (
Fig. 47
).

Natural history.
Most individuals were collected with a beating tray and, hence, the species can be considered arboreal. Some individuals were collected in a natural formation of “butiazal” (
Butia
spp.
) and in Riparian Forest (see
Rodrigues
et al
. 2014
,
2016
). Species occurs between 10 and
900 m
a. s. l.
