Etymology.The specific name, a noun in apposition, honours the Brazilian rock band “Turbo”, created in 2005 inBelém (capital of the state of Pará, near the typelocality of this species).
Diagnosis.Males and females of T. turbo sp. nov.resemble those of T. agatelin, T. huaoand T. metzneri Bustamante & Ruiz, 2017by the general appearance of the body (brown carapaces, with white scales pointing to the sides; abdomen with white chevrons dorsally; compare Bustamante & Ruiz 2017figs 18, 20, 22 with our figures 39–42). Males resemble those of T. huaoand T. metzneriby the long cymbial dorsal depression, but differ from T. metzneriby the larger RvTA and the shape of the RTA (triangular in T. metzneriand subtriangular with a wider base in T. turbo sp. nov., see Figs 43–47), and from T. huaoby the longer embolus (935°, 2T+215°, in T. agatelin; 980°, 2T+260° in T. turbo sp. nov.), by the smaller RvTA and the shape of RTA (strongly curved in T. huaoand slightly curved with a wider base and in T. turbo sp. nov., see Figs 43–47). Females resemble those of T. agatelinby having a bilobed posterior border of the epigyne, but differ by having globular spermathecae. Females of T. turbo sp. nov.resemble those of T. huaoand T. metzneriby their similar internal copulatory ducts and spermathecal pattern (small and spherical), but differ by the shape of the copulatory openings (C-shaped in T. huaoand T. metzneri, upside down U-shaped in T. turbo sp. nov., see Figs 48–51).
