Diagnosis. Somatically the species can be differentiated from Z. magna by its dorsal eye field occupying 41-42% of the total length of the prosoma (Figs. 8-9), two promarginal and one retromarginal teeth (Fig. 7), prosoma with slightly marked radiating prosomal grooves and abdomen coloration with a mixture of white-brown transverse stripes, and with two-four longitudinal, ventral brown marks (Figs. 4-5, 8-9). Males can by distinguished by the slender and not dilated femur of the palp, with the embolus rotated ventrally (Figs. 1-2). Females can be separated from those of Z. magna by the epigyne, with smaller pits, a chitinous septum that does not reach the height of the spermathecae on the anterior side of the epigyne (Fig. 6), and copulatory ducts that are shorter and not convoluted. For more diagnostic characters see Galiano (1964a: 70). Although the sternum of the species as described is wider and shorter than that of Z. magna (see Galiano, 1964a: 71, fig 5), here I present a specimen with a narrower sternum (Fig. 3).
Distribution. Colombia (Boyacá, Magdalena), Brazil (Minas Gerais, Rio de Janeiro, Paraná, Santa Catarina, Rio Grande do Sul) and Argentina (Jujuy) (Fig. 19). This includes new northernmost, southernmost and altitudinal records for the species, and new genus records from Argentina and Colombia. In Brazil this includes new records from the southern states of Paraná and Santa Catarina, and Rio Grande do Sul, after Buckup et al. (2010). The known altitudinal range is 7-2800 m.
These are the first records of this species since its original description (Galiano, 1964a). In Colombia, the species was collected beating vegetation in a grassland near an intervened high Andean wet forest, and near to a road in a highly conserved Andean wet forest at the Sierra Nevada de Santa Marta (Fig. 17). There is an unconfirmed record of the species from Brazil, Amazonas, Humaitá, Humaitá (SMNK 2901) listed by Heiko Meztner (Meztner, 2015; Fig. 19).
