Type material. Holotype: ♂ from Serra das Andorinhas (06°13’10.47”S, 48°26’17.97”W), São Geraldo do Araguaia, Pará, Brazil, 30.X–7.XI.2011, leg. A.B. Bonaldo et al., collected with pitfall traps ( MPEG 35480 View Materials ) GoogleMaps   . Paratypes: Same data as the holotype, 1♀ ( MPEG 35481 View Materials ), 1♂ ( MPEG 35482 View Materials ) GoogleMaps   .

Etymology. The specific name is a noun in apposition after the type locality.

Diagnosis. Males of Tupirinna araguaia   sp. nov. differ from those of all other species with ventral lobe of RTA not divided basaly ( T. rosae   , T. platnicki   sp. nov., T. regiae   sp. nov. and T. mutum   sp. nov.) by the tegulum strongly pronounced retrolaterally and by the absence of an apical tegular projection ( Fig. 9E, F View FIGURE 9 ). Females resemble those of T. mutum   sp. nov. by the rounded copulatory opening but can be recognized by the concave posterior margin of the epigynal plate ( Fig. 9G, H View FIGURE 9 ).

Description. Male holotype (MPEG 35480). Carapace yellow, with brown stripe extending over ocular area, and brown lateral stripes. Chelicerae dark brown. Labium brown. Endites brown. Sternum and borders yellow, with anterior lateral excavations brown. Legs yellow, with proximal and distal region of lateral surfaces of tibiae black and lateral surfaces of patellae I and II black. Abdomen dorsum yellow, with one pair of black longitudinal spots in cardiac area; in median region, one pair of black spots on each side followed by three black spots, subsequently one subretangular black spot.

Female paratype (MPEG 35481). Carapace yellow, with brown stripe extending over ocular area, and brown lateral stripes. Chelicerae dark brown. Labium brown. Endites brown. Sternum and borders yellow, with anterior lateral excavations brown. Legs yellow, with proximal and distal region of lateral surfaces of tibiae black and lateral surfaces of patellae I and II black.
