Diagnosis. According to Bayer et al. (2020), the females of Corythalia spiralis ( Figures 34, 36 ), can be distinguished from females of all other Corythalia species by their lack of epigynal windows, and the rather spiral or helical structure of epigynal ducts ( Figure 36 ; see Bayer et al. 2020, figs. 54C, 55A 74H). In dorsal view the epigyne has slightly widened secondary spermathecae, distinctly rounded at the front with a straight margin at the rear, primary spermathecae slightly widened and clearly elongated, vulva with an elongated blind sac lateral to the primary spermathecae (see Bayer et al. 2020, figs. 54D–E, 55B– C, 78G–H). This blind sac is wider and longer than the primary spermathecae (see Bayer et al. 2020, figs. 54D, 55B, 78G–H).

Measurements (mm; specimens from Colombia). Three females: TL= 5.9-6.1; CL= 3.02-3.1; CW= 2.27-3.1; AL= 3.1-3.3; AERW = 1.98-2.1; PERW = 1.7-19; LOQ= 1.9-2.0; PMEP =0.25-0.27; eyes of the second row separated from the ALE by 0.35 mm and from the PLE by 0.28-0.31mm.

Distribution: Corythalia spiralis is known from Colombia, Venezuela, French Guiana, and Brazil.
