Diagnosis. Males of G. guayaquilensis differ from others species by the reduced and narrow tegular process (Fig. 13A–B) and by the blunt and dorsally projected patellar apophysis (Fig. 13B–D) in the male palp. Female differs by the epigynum with posterior border straight (Fig. 13E), thin spermathecae when compared to the copulatory ducts (Fig. 13F), and vertical spermathecae short, with half of the height of the copulatory ducts (Fig. 13F).
