The female of <i>E. delasmata</i> (Figs 13–16) has an epigynum similar of those of <i>E. ulecebrosa</i> (see Poeta 2014, figures 69–73), by the annulated scape (Figs 13, 15). <i>Eustala delasmata</i> can be separated from this species by the wide and almost parallel lateral plates (posterior view, Fig. 14), which are narrow in <i>E. ulecebrosa</i> (see Poeta 2014, figure 71).</p> <p> <b>Description.</b> <i>Male</i> (holotype, MCZ): Carapace orange, with brown dusk marks (Fig. 12).

O gênero Eustala (Araneae, Araneidae) no sul do Brasil: duas espécies novas, descrições complementares e novas ocorrências The genus Eustala (Araneae, Araneidae) in southern Brazil: two new species, complementary descriptions and new records
Eustala levii sp. nov. e E. palmares sp. nov. são descritas do Rio Grande do Sul, Brasil, com base em ambos os sexos. Os machos de E. albiventer (Keyserling, 1884), E. taquara (Keyserling, 1892) e E. photographica Mello-Leitão, 1944, são descritos pela primeira vez e as fêmeas são redescritas. Eustala sanguinosa (Keyserling, 1893) é considerada sinônimo de E. albiventer. Eustala photographica, descrita da Argentina, é registrada pela primeira vez para o Brasil. Novas ocorrências ampliam a distribuição geográfica de E. minuscula (Keyserling, 1892) e E. saga (Keyserling, 1893).Eustala levii sp. nov. and E. palmares sp. nov. are described from Rio Grande do Sul, Brazil, based on both sexes.
