Diagnosis. The male of Thymoites taiobeiras n. sp. differs from other species by the femur and tibia I enlarged and tibia I–II with ventral and dorsal macrosetae (Fig. 18), resembles that of T. villarricaensis Levi, 1964 (see Levi, 1964: figs. 39, 42) in the form of the carapace, high and unmodified in ocular area (Figs. 16, 17), but differs in the presence in ocular area of two setae, trajectory of the sperm duct in the tegulum (Fig.16), conductor pointed and the shape of tibia of palp (Fig. 15). The female of Thymoites taiobeiras n. sp. is close to T. villarricaensis Levi (see Levi, 1964: figs. 40, 41) by the long and not coiled copulatory duct (Figs. 19, 20), but differs by the larger spermathecae and “S” shaped copulatory duct (Fig. 20).
