Etymology. The specific name is a noun in apposition taken from the type locality.

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 ).
