Oxysarcodexia paulistanensis (Mattos, 1919) ( Figs. 2 , 11A , and 12A )

Description – differs from male in the following: Two proclinate orbital setae, the superior one with half length of the inferior; inner vertical setae differentiated from postocellar setae. Tergite 5 with a dorsolateral light golden spot. Tergite 6 divided, the median region connecting the two plates are sclerotized; spiracle 6 in membrane and 7 within the sclerites. Six to eight strong marginal setae accompanied by thin setae. Tergite 7 absent. Tergite 8 as two lateral bare plates, relatively pigmented, centrally extended and tapered at the top and bottom, joined by a membrane. Epiproct absent. Sternites 2–6 rectangular with rounded corners with strong setae in the posterior margin and weak setae in the median part; sternite 6 shorter and wider on comparing to sternite 5; sternite 7 wider than 6 with 3 strong setae in each lateral and some setulae; sternites 6, 7 and 8 fused; sternite 8 broadly membranous with an small marginal sclerotized area with setulae. Vaginal plate present, well sclerotized, almost the same size as hypoproct, rectangular, with concave posterior margin and central area with a depression. Spermatheca elongated and slightly oval with transversal striations in all extension.

Distribution: Argentina (Buenos Aires, Córdoba, Entre Ríos), Brazil (Distrito Federal, Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul, São Paulo), Chile (Santiago).

Material examined: eight females from colonies initiated by specimens collected in Brazil, Paraná, Curitiba , ii. 2011. K. Vairo col.
