Figs 6 View FIGURE 6 A–D

Type-material. Holotype: male from São Félix do Araguaia   , Mato Grosso, Brazil, (11 ° 36 ' 36 "S; 50 ° 39 ' 36 "W) XII/ 1972, I. Frasceschini col., deposited in IBSP 2605.

Etymology The species epithet is a noun in apposition taken from type locality.

Diagnosis Males of Catanduba araguaia   sp. nov. differ from those of other species by the presence of an auxiliary keel under PIK with a pointed apical edge, as C. piauiensis   sp. nov. ( Figs 6 View FIGURE 6 A–C). Differ C. piuaiensis   sp. nov. by the presence of the curved apical portion of the metatarsus I basal nodule ( Fig 6 View FIGURE 6 D).
