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). Paratypes: BRAZIL: Same locality as holotype (04°48’56’’S, 65°01’53’’W), 2.IX.2006, leg. D.F. Candiani, 1♀ (MPEG 35513), 1♀ (MPEG 35512).

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). 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).
