Tartamura turbo sp. nov.

Figs 3–6, 39–51

Etymology. The specific name, a noun in apposition, honours the Brazilian rock band “Turbo”, created in 2005 in Belém (capital of the state of Pará, near the type locality of this species).

Diagnosis. Males and females of T. turbo sp. nov. resemble those of T. agatelin, T. huao and T. metzneri Bustamante & Ruiz, 2017 by the general appearance of the body (brown carapaces, with white scales pointing to the sides; abdomen with white chevrons dorsally; compare Bustamante & Ruiz 2017 figs 18, 20, 22 with our figures 39–42). Males resemble those of T. huao and T. metzneri by the long cymbial dorsal depression, but differ from T. metzneri by the larger RvTA and the shape of the RTA (triangular in T. metzneri and subtriangular with a wider base in T. turbo sp. nov., see Figs 43–47), and from T. huao by 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. huao and slightly curved with a wider base and in T. turbo sp. nov., see Figs 43–47). Females resemble those of T. agatelin by having a bilobed posterior border of the epigyne, but differ by having globular spermathecae. Females of T. turbo sp. nov. resemble those of T. huao and T. metzneri by their similar internal copulatory ducts and spermathecal pattern (small and spherical), but differ by the shape of the copulatory openings (C-shaped in T. huao and T. metzneri, upside down U-shaped in T. turbo sp. nov., see Figs 48–51).
