Diagnosis. Males of E. stitch sp. nov. are easily recognized by having a retrolateral apophysis with constricted
base on the palpal patella, palpal tibia with retrolateral concavity giving rise to a basal apophysis, RTA lanceolate and retrolaterally directed and basal portion of the RTA digitiform. Females present elliptical epigynal plate and Vshaped spermathecae with external base (Figs 22, 23).
Etymology. The specific epithet is a noun taken in apposition and is in reference to Stitch, a fictional character in Disney’s Lilo & Stitch franchise. The shade of the colors of its ears resembles the spermathecae from ventral view.
