Males of species of the genus Tafana resemble those of the genera Aljassa Brescovit, 1997, Aysha Keyserling, 1891, Hibana Brescovit, 1991, Hatitia Brescovit, 1997, Osoriella Mello-Leitão, 1922, Pippuhana Brescovit, 1997, Temnida Simon, 1896, Umuara Brescovit, 1997 and Xiruana Brescovit, 1997 by having an embolic process in the internal male palp (see Brescovit 1997: 176–187, figs 221, 247, 265, 272, 280), an apophysis at the base of the embolus (see Oliveira & Brescovit 2015a: 209, fig. 5a–b) and further resemble Umuara by having a ventral tegular process near the median apophysis in the male palp (see Oliveira & Brescovit 2015b: 438, figs 2a–b), but differ by the presence of a conical or coiled laminar apophysis at the base of the embolus (Figs 9C–F, 12B, C, 23B, 26A–B). The females resemble those of Anyphaena, Patrera Simon, 1903, Iguarima Brescovit, 1997, Umuara and Pippuhana (see Brescovit 1997: 139–187), by having a hood on the anterior fold of the epigynum, but differ by having the posterior extension forming the lateral lobes (Figs 7D, 10F, 22F, 32E–F, 33D–E), lateral lobes sinuous (Figs 17F, 19F) and posterior region of the epigynum covered by cuticle (Figs 10F, 17F, 21F).

Oval abdomen, tracheal spiracle curved in the middle of the abdomen in ventral view (Figs 7B, 8L); anterior spinnerets bisegmented, with basal article large and distal article circular, with several spigots of piriform gland and one spigot of the ampullate gland (Fig. 8C–D); median spinnerets unsegmented, with several spigots of the aciniform gland and not presenting spigots of the cylindrical gland (Fig. 8C, E); posterior spinnerets bisegmented with basal and distal article cylindrical, one third longer than the others, with several spigots of the aciniform gland and one spigot of the ampullate gland without spigots of the cylindrical gland (Fig. 8C, F); colulus substituted by 8–10 setae (Fig. 8C). Epigynum with sinuous lateral lobes, lobe parallel in the posterior region (Figs 10F, 22F); hood approximately triangular (Figs 10F, 16F, 25F, 27F), semicircular (Figs 11F, 14F, 32D) or circular (Figs 15F, 17F, 30F, 32J, 33G– H) in the anterior region; posterior region with cuticle covered the lateral lobes (Figs10F, 11F, 17F, 21F, 27F) or without (Figs 13F, 15F, 16F, 28F); atrium with septum in the anterior region (Figs 11F, 14F, 21F) or without (Figs 13F, 15F, 22F, 25F); copulatory ducts sinuous (Figs 10G, 11G, 19G, 32F–I) or coiled (Figs 13G, 16G, 32H, K), running along margin of the lateral lobes, reaching the spermathecae, visible through transparency; secondary spermathecae rounded (Figs 10G, 11G, 14G, 32F–G, I, 33B–C) but may be irregular or inconspicuous (Figs 13G, 28G, 29G, 32H, 33F–G); secondary spermathecae short, near the primary spermathecae (Figs 15G, 17G, 22G, 26D, 32F, J, L), wide (Figs 11G, 13G, 14G, 32G, I) or in the middle of the copulatory ducts (Figs 16G, 21G, 29G, 32K, 33G); primary spermathecae oval, positioned together (Figs 10G, 15G, 20E, 22G, 26D, 32F–G) or separated from each other by almost a third of their diameter (Figs 13G, 28G, 29G, 33F–H); fertilization ducts near the epigastric furrow, originating from base of spermathecae (Figs 10G, 11G, 20E, 22G, 26D, 29G, 32F–L, 33A–H).
