Update diagnosis based on the holotype and common specimens: Areola postica with light brown spot around Cua1 and Cua2,giving the shape of a halo ( Figs.12B , 13 A-B, 14A, 15B,18B). Posterior process of the edeagal arch long and narrow with slight indentation of outer margin; endophallus with sharp spines directed antero-mesally, with long spicules on outer margin and dense field of short spines and spicules latero-posteriorly( Fig.18H ).Ninth sternum almost circular ( Figs.12G , 15J ),without pigmented areas,with invagination in the center ( Figs.12 F-G,15I-J). Gonapophyses long and slender, acuminate distally, with V2 strongly sclerotized with six microsetae on the outer lobe; V3 weakly sclerotized,thin, and elongated ( Figs. 12I , 15G ).

Male: As described by Mendivil Nieto et al. (2020).
