description
Figs. 10 - 16
diagnosis
Diagnosis. Somatically the species can be differentiated from Z. laeta by the dorsal eye field occupying 34 - 38 % of the total length of the prosoma (Figs. 10, 14), with distinct radiating prosomal grooves and a brown prosoma and abdomen (in alcohol and in life), with an “ inverted-V ” white mark above the abdominal constriction (Figs. 10, 13 - 14). Males can distinguished by the short and distally dilated femur of the palp, with embolus directed forward (Figs. 15 - 16). Females can be distinguished from those of Z. laeta by their epigyne, with larger rounded pits (Fig. 12), and the chitinous septum reaching the height of the spermathecae on the anterior side, and copulatory ducts longer and convoluted. For more diagnostic characters see Galiano (1964 a: 70). The specimen shown here has a slender sternum (Fig. 11).
distribution
Distribution. Mexico (San Luis Potosí), Costa Rica (Heredia), Panama (Canal Zone Biological Area, Barro Colorado Island), British Guiana (Cuyuni-Mazaruni region), Colombia (Valle del Cauca), Brazil (Amazonas, Bahía, Espirito Santo, São Paulo, Paraná), Peru (Loreto), and Argentina (Misiones) (Fig. 19). This includes new northernmost and southernmost records for the species, and new genus records for Argentina (Misiones Province, after Rubio, 2014) and Colombia. In Brazil, this includes new records from the Amazonas, Bahía and Espirito Santo states. The known altitudinal range is 0 - 800 m. Mexican records of the species are based on the high-definition diagnostic images of the Alvarez-Padilla Laboratory (2014). This species has been collected in a conserved low-land Chocoan wet forest in Colombia (Fig. 18), beating vegetation in a second-growth clearing forest in Costa Rica (Bodner, 2002), and a 25 - 35 year old remnant tropical forest in México (Alvarez-Padilla Laboratory, 2014). There are some unconfirmed records of the species from Peru, Junín (MCZ 25866) and Costa Rica, Guanacaste (MCZ 25666) identified by M. E. Galiano and G. Bodner in the MCZ on-line catalogue, respectively (Fig. 19).
