T4‒T7 mostly with yellowish pubescence, longer and denser towards the apex of metasoma (Fig. 18). Claws of middle and hind legs with a tuft of plumose hairs at the base (Fig. 18).

Type locality. MEXICO: Michoacán State: Uruapan (latitude: 19.482; longitude: 102.004; 1943 masl).
Etymology. The epithet refers to the indigenous ethnicity Pur’hepecha who inhabits the State of Michoacán, the place where the holotype was collected. This new species is dedicated in their homage.

Comment. Considering the light pubescence on the distal segments of the metasoma, Centris purhepecha sp. nov. looks similar to C. carolae. However, these species are easily recognized by the pubescence on the dorsal surface of the mesoscutellum (dark brown to black in C. purhepecha sp. nov. (Fig. 14); yellow in C. carolae), by the coloration of the clypeus and labrum (blackish in C. purhepecha sp. nov. (Fig. 13); dark reddish brown in C. carolae), and by the pubescence on head (blackish in C. purhepecha sp. nov. (Fig. 13); whitish in C. carolae). This new species is also superficially similar to C. aureiventris Vivallo, Vélez & Fernández, 2013, a South American species that occurs in mountainous areas of Colombia and Peru (Vivallo et al., 2013). However, they differ by the position of the inner orbits of the compound eyes (almost parallel-sided in C. purhepecha sp. nov. (Fig. 13); converging downward in C. aureiventris), by the pubescence on the ventral surface of mesepisternum (blackish in C. purhepecha sp. nov. (Fig. 14); white yellowish in C. aureiventris), and on the distal segments of the metasoma (light yellowish brown in C. purhepecha sp. nov. (Fig. 14); yellowish in C. aureiventris).
