Figs 1-5

Attus cancrimanus Taczanowski, 1872: 68 ( male lectotype and male and juvenile paralectotypes from Uassa , French Guyana, R. Jelski leg., deposited in Polska Akademia Nauk, not examined ).

Helvetia zebrina Simon, 1901b: 158 ( female lectotype and female paralectotype from Mato Grosso, Brazil, Germain leg., deposited in MNHN 21184 , examined ); Galiano, 1963a: 362, pl. XIX, fig. 15; Platnick, 2007. Syn. nov.

Helvetia zonata Simon, 1901b: 158 ( female holotype from São Paulo de Olivença, Amazonas, Brazil, de Mathan leg., deposited in MNHN 20726 , examined ); Galiano 1963a: 363, pl. XIX, fig. 14; Galiano 1963b: 3, pl. I, fig. 1-6; Platnick, 2007. Syn. nov.

Deloripa quadrifasciata Mello-Leitão, 1945: 280 , fig. 71 ( female holotype from Goya, Corrientes, Argentina, deposited in Museo de la La Plata 16760 , not examined ). Synonymized by Galiano, 1963b: 3.

Helvetia cancrimana: Galiano, 1976: 51 , figs 1-7; Platnick, 2007.

Note. Since the type specimens of Attus cancrimanus have not been examined, the synonymy is established based on the very good illustrations by GALIANO (1976, figs 1-7).

Diagnosis. Males of Helvetia cancrimana are similar to those of H. humillima by having a RTA with a very developed dorsal branch ( Fig. 18 ; see GALIANO 1976, fig. 5), but differ by not having a ventral tiny projection on the base of the RTA and by having a shorter embolus.

Description. Male. Described by GALIANO (1976: 53).

Female. Described by GALIANO (1963a: 363, under H. zonata ).
