Diagnosis. Both sexes have lateral setae on the carapace margins, a character exclusive in relation to other native American species. Males can be distinguished from those of the American species by the dorsal V-pattern on the abdomen (see IZQUIERDO & RAMÍREZ, 2017:24, fig. 11A-C) and by the shape of the embolus, sinuous and with distal extensions ( Fig. 51 View Figs 49-57 ; IZQUIERDO & RAMÍREZ, 2017, figs 17D-F, 20N, O). Females have genitalia with external pockets and an anterior receptaculum widened at its base with V-shaped anterior apodemes at the tip ( Fig. 52 View Figs 49-57 ; IZQUIERDO & RAMÍREZ, 2017:24, figs 19G, 22D).

Description. Male and female, see IZQUIERDO & RAMÍREZ (2017: 24).

Biology. According IZQUIERDO & RAMÍREZ (2017) this species has been introduced into many countries and its natural origin is still unknown. In Argentina, it has been collected in disturbed environments and in houses or other human buildings. Specimens were observed walking on walls, furniture and collected in leaf litter. In Brazil, it has been collected in the interior of houses as well as in the interior of disturbed caves.

Distribution. According to IZQUIERDO & RAMÍREZ (2017), this species occurs in Israel, United States, Portugal, Brazil, and Argentina ( Fig. 61 View Figs 60, 61 ).

Material examined. In addition to the Brazilian material recorded to the states of São Paulo and Minas Gerais by IZQUIERDO & RAMÍREZ (2017), only one specimen is reported here, from state of São Paulo, São Paulo, campus of Instituto Butantan, building of LECZ, collected manually on the table, ♀, 26.VII.2017, A.
