Diagnosis. Males of E. vader sp. nov. are easily recognized by having black carapace, palpal tibia with row of median bristles in the proximal/medial portion of the retrolateral margin, a diagonal elevation that begins proximally/retrolaterally and ends distally/prolaterally with a central bristle tuft, a depression in front of this elevation until to the base of the RTA. Females also have black carapace, epigynum with open triangular atrium on top (Mshaped) (Figs 28, 29).
Etymology. The specific epithet is a noun taken in apposition and is in reference to Darth Vader, a fictional character in George Lucas film, “Star Wars”. Darth Vader is a character which wears a costume and black helmet, like the color of the male carapace.
