TYPES: Female holotype from Brazil: Amazonas : Manaus , Igapó, Tarumã-Mirim (-3.03306°, -60.15750°), July 30, 1979, J. Adis et al., deposited in IBSP 17260, PBI_OON 43325 ; same data, 1 female paratype deposited in IBSP 17274, PBI_ OON 30290 .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Females can be distinguished by the shape of the genitalia, with an internal transverse sclerotized structure at the midline (probably an apodeme) and internal pockets widely separated, placed almost at the end of the epigastric furrow (figs. 134E, 137F, 142C).

MALE: Unknown.

FEMALE (PBI_OON 43325): CEPHALO- THORAX (fig. 119): Carapace length 0.63. Sternum longer than wide. Labium rectangular. ABDOMEN: Epigastric region weakly sclerotized. LEGS: Yellow. GENITALIA: As in diagnosis, external pockets absent; anterior receptaculum wide at base, anterior tip wide; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 134E, 137F, 142C).
