Eustala davalosae is a species of orb-weaver spider and can be found in Southern Paraguay.[1]
Eustala davalosae is a relatively small spider. The female is around 5.5 mm (0.2 in). It is characterized by its wide epigynal plate.
The specific epithet "davalosae" is a tribute to Serafina Dávalos Alfonze, the first female lawyer in Paraguay and a prominent feminist.
