Goeldia mexicana differs from the other species by the male palp with tegular process triangular, short, and distally narrowed ( Fig. 15A ); and patellar apophysis straight, triangular, with tip rounded ( Fig. 15B–C ). The female epigynum can be recognized by its median field well developed, resembling G . luteipes but differing by the median area posteriorly projected ( Fig. 15E ); apex of the copulatory ducts dorsally projected, with enlarged bases and vertical spermathecae short ( Fig. 15F ).
