Type-material. Holotype: male from Cana Brava, Minaçu, Goiás, Brazil, (13°50'01"S; 48°18'10"W), 03/V/1935, J. Blaser col., deposited in IBSP 3735. Paratype: two males from the same locality and collector as holotype, deposited in MZSP 36507 and IBSP 160893.

Additional material examined. BRASIL, Goiás, Minaçu, Cana Brava, (13°50'01"S; 48°18'10"W), XII/1972, I. Frasceschini col., 33 ( IBSP 160894 – 160896).

Etymology. The specific name is a noun in apposition that refers to the type locality of the holotype.

Diagnosis. Males of C. canabrava sp. nov. differ from those of other species by the position of the embolus tooth in the middle of the PIK ( Figs 7 A–C).

Palpal bulb with weak PIK and conspicuous PSK. Thin embolus with tooth emerging from middle of PIK.

Digitiform apophysis weakly developed ( Figs 7 A–C). Tibial apophysis formed by two branches with distinct bases: prolateral smaller, with retrolateral spine; retrolateral larger. Metatarsus I with basal triangular nodule and flexes between tibial apophysis branches, touching their median portion ( Fig 7 D). Female. Unknown.
