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.
