Type material. Lectotype female and paralectotype immature male, here designated, from Brazil, state of São Paulo, Itapetininga, Bicego col. ( MZUSP 28 ), examined ( Figs 297 ─299).

Remark. The lectotype has stridulatory setae on retrolateral trochanter of palp (Fig. 298), sternum rounded and convex ( Fig. 297 ) and spermathecae completely fused (even though two vestiges of receptacles can be seen on its distal portion) (Fig. 299). There is no doubt it belongs to the genus Acanthoscurria and, therefore, it is transferred to it making the new combination Acanthoscurria sternalis ( Mello-Leitão, 1923) n. comb. However, there is already a species with the same name, Acanthoscurria sternalis Pocock, 1903 , a junior synonym of Acanthoscurria musculosa Simon, 1892 . Therefore, it is necessary to establish a new name to replace the homonymy.
