Remarks

According to Flint (1983), this species is most closely related to a Central American group of species. However, as discussed in the diagnosis for A. vitalbrazili sp. nov., the closest relationship of these two species is with each other, distinguished by structures of the intermediate and inferior appendages. Austrotinodes paraguayensis can be diagnosed by the large truncate apex of the intermediate appendages, with a short apical process and 4 spine-like setae; inferior appendages with the posterior margin convex, bearing a short U-shaped incision; and a phallic apparatus with a dark basomesal process, a lateral process bearing a robust, upturned dorsal branch, with a large, rugose apical spine, and an elongate ventral branch, with a slender, curved, rugose apical spine. The phallic guide is elongate, but without an almost truncate apex, as described by Flint & Denning (1989) for specimens collected in Serra do Cipó, Minas Gerais state. Rather, it has a finger-like apical projection. As in A. amazonensis , the genitalic structure of this species is also reillustrated to facilitate comparison with others species of the genus.

We report here records of A. paraguayensis collected in the Serra da Canastra, a mountainous area in Minas Gerais state. Additionally, this species was also collected and is reported for the first time from Pará state, north Brazil, based on a single specimen collected in the Floresta Nacional de Carajás, an outstanding conservation area with typical Amazon tropical forest. The forested areas are interrupted by natural clearings, where there are rocky outcrops of iron, generically called “Canga,” covered with savannah vegetation.
