Tasata albofasciata Mello-Leitão, 1943: 238, fig. 65 (♂ and ♀ syntypes from Rio Grande do Sul, Brazil, leg. B. Rambo, MNRJ 42.526, male lost; female examined and designated here as lectotype).
Tupirinna albofasciata Ramírez, 2003: 230.
Note. The male paralectotype of Tupirinna albofasciata, from Rio Grande do Sul, was not found in MNRJ. We were not able to find a male specimen matching the female here described and the only source of information on the male form of this species remains the original description. Nevertheless, judging by the illustrations presented (Mello-Leitão 1943: fig. 65, 65a), the male lectotype is indeed an Anyphaenidae (Tasata Simon, 1903, according to A.D. Brescovit, personal communication). The vial MNRJ 42.526 contains only one female specimen, designated here as the lectotype. Ramírez (2003: 230), when correctly transferring this species to Tupirinna, mistakenly referred to the syntypes as MNRJ 670. This vial actually contains the syntypic series of Tasata taperae (Mello-Leitão, 1929).
Diagnosis. Females of T. albofasciata share with those of T. palmares sp. nov. the epigynal plate with a welldefined median depression, differing by the median depression being sub-rectangular (Fig. 17E, F).

Labium brown. Endites pale yellow. Sternum and borders yellow, with anterior lateral excavations pale brown. Legs brownish. Abdomen dorsum yellow, with one pair of longitudinal brown spots in cardiac area; in median region, two pairs of brown spots on each side; subsequently two brown spots in middle, followed by huge brown “U” spot.
