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.
