TYPE: Male holotype from Brazil: Amazonas: Presidente Figueiredo: Usina Hidrelétrica de Balbina, -1.81666°, -59.41666°, July 14, 2006, R. Saturnino, deposited in MPEG 010664, PBI_ OON 40480.

ETYMOLOGY: A noun in apposition; because, while analyzing this species, the first author was listening to Die Walküre (“The Valkyrie”), an opera by Richard Wagner, we decided to give its name to this species.

DIAGNOSIS: Males can be distinguished by the presence of a short embolus flanked by a short apophysis and a highly coiled sperm duct (figs. 131D–F, 140A, C). Females can be distinguished by the absence of anterior apodemes on the anterior receptaculum and by the lateral projections, emerging near median half of the anterior receptaculum (figs. 134D, 137E, 142B).

MALE (PBI_OON 40480): Total length 1.40. Habitus as in figure 118A–C. CEPHALOTHO- RAX: Carapace orange. Labium rectangular.

LEGS: Yellow. GENITALIA: Palp proximal segments yellow, cymbium yellow; embolus short; sperm duct strongly coiled, with many loops (figs.131D–F, 140A, C).

FEMALE (PBI_OON 40491): Total length 1.55. Habitus as in figure 118D–F. CEPHALOTHO- RAX: Carapace pale orange. Sternum as long as wide, yellow. Chelicerae, endites, labium yellow.

GENITALIA: External pockets absent, internal pockets well developed; anterior receptaculum without anterior apodemes, nearly triangular, with widened lateral projections at base; posterior receptaculum present, posterior apodeme formed by entire plate (figs. 134D, 137E, 142B).

DISTRIBUTION: states of Amazonas, Pará, Amapá, Piuaí, and Tocantins, Brazil (map 26).
