Diagnosis. S. tocantinensis ( Fig. 10 ) are recognized by the combination of the following morphological characteristics: a. forewing weakly falcate, Sc and R fused on the pterostigma, one radial crossvein, three or four Rs longitudinal veins, six inner gradate crossveins and two outer gradate ( Fig. 11 ); b. male terminalia: ectoproct with a hooklike projection on the tip; tenth gonocoxite (mediuncus) spirally coiled ( Figs. 15-16 ); eighth sternite with a thin projection on each posteroventral corner, each projection with tip slightly curved dorsally, and bearing one strong setae on the tip ( Figs. 15-16 ); ninth sternite with a pair of projections on posterior margin, each projection straight with two strong setae on the tip ( Figs. 15-16 ) and, c. female terminalia ( Figs. 12-14 ): eighth gonocoxite extending downwards, subtriangular, with posterior margin rounded and bearing two elongate lateral tubercles ( Figs. 12-13 ); ninth tergite and ectoproct fused with the ventral margin expanded downward with tip rounded and bearing some long setae ( Figs. 12-13 ); ninth gonocoxite with posterior margin rounded and set with black setae and ventral margin bearing hypocaudae ( Figs. 12-13 ); hypocaudae very long covered with elongate pale setae, mainly on the internal face ( Figs. 12-13 ) ( Machado and Krolow 2016) and, bursa-copulatrix-spermatheca complex comprising a small, sclerotized ball-shaped element; a short fertilization canal and elongate spermathecal duct expanded apically ( Fig. 14 ).

Geographical distribution ( Fig. 9 ): S. tocantinensis was known only from Palmas, Tocantins state, Brazil, its type locality ( Machado and Krolow 2016; Machado and Martins 2019); this new record extends its geographic distributional range about 400 km southeast from the type locality.
