Remarks

Austrotinodes amazonensis  can be easily distinguished from other species of the genus by the deeply divided apex of the elongate phallic guide, intermediate appendages with a short ventral projection in the basal half, bearing an apical spine-like seta, and the unusual lateral process of the phallus, with the ventral branch forked. Other important characteristics of this species are the elongate segment IX with a strongly convex posterior margin and the inferior appendages with a wide V-shaped incision (best observed in ventral view). Additionally, the phallic apparatus has a dark basomesal process. For comparative purposes, A. amazonensis  is reillustrated here in order to better observe the male genitalic structures, especially the phallic apparatus.

Austrotinodes amazonensis  is reported here for the first time from Minas Gerais state, southeastern Brazil, based on a specimen collected in the Serra da Canastra mountain range in the Atlantic Forest- Cerrado ecotone site. This is the first reported occurrence of this species outside of its Amazon core distribution.
