Type material. Holotype: ♂ from Base de Operações Geólogo Pedro de Moura , Porto Urucu (04°53’04.8’’S, 65°09’12.4’’W), Coari, Amazonas, Brazil, 12.VII.2003, leg. M.C.S. Costa ( MPEG 35484 View Materials ) GoogleMaps . Paratypes: BRAZIL: Same locality as holotype (04°48’56’’S, 65°01’53’’W), 2.IX.2006, leg. D.F. Candiani, 1♀ ( MPEG 35513 View Materials ), 1♀ ( MPEG 35512 View Materials ) GoogleMaps .

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

Diagnosis. Males of Tupirinna coari sp. nov. resemble those of T. gigantea sp. nov. by the embolus short and directed retrolaterally, and by the long, narrow AS, but can be distinguished by the simple, comma-shaped embolus without an extended tip ( Fig. 12A, B View FIGURE 12 ). Females resemble those of T. gigantea sp. nov. by the epigynal plate concave, but can be recognized by the copulatory opening positioned anteriorly, surrounded by a dark, rounded spot ( Fig. 12C, D View FIGURE 12 ).

Description. Male holotype (MPEG 35484). Carapace orange, with brown stripe extending over ocular area, and dark brown lateral stripes. Chelicerae dark brown. Labium brown. Endites brown. Sternum yellow, with borders and anterior lateral excavations brown. Legs yellow, with lateral surfaces of patellae black; proximal and distal regions of lateral surfaces of tibiae black. Abdomen dorsum yellow, with pair of black longitudinal spots in cardiac area; in median region one huge subrectangular black spot, with two pairs of yellow spots inside. Contour of spinnerets black; venter yellow, with brown rectangular spot ( Fig. 4E View FIGURE 4 ). Total length 4.50. Carapace length 2.43, width 1.98, height 1.14. Clypeus height 0.19.

Palp: tibia almost equal to half cymbial length; ventral lobe of retrolateral tibial apophysis with apical spur; dorsal lobe absent; ventral tibial apophysis with median longitudinal protuberance; embolus short, embolar basal process (TEP) present; tegular retrolateral process small, pointed ( Fig. 12A, B View FIGURE 12 ).

Female paratype (MPEG 35513). Carapace yellow, with small black spot on central area, and black lateral stripes. Chelicerae yellow. Labium yellow. Endites yellow. Sternum with borders and anterior lateral excavations brown. Legs yellow.
