Etymology. The specific ephitet is a noun in apposition referring to the Quilombo dos Palmares, in the State of Alagoas, Brazil. Quilombos were settlements founded by escaped slaves during Brazilian colonial period.

Diagnosis. Males of Tupirinna palmares sp. nov. resemble those of T. lata sp. nov. by the TEP dorsal to the embolus, but differ by the RTA sub-apical dorsal lobe represented by a small hump and by the wide-based, sub-triangular embolus ( Fig. 17A, B ). Females share with those of T. albofasciata the epigynal plate with a well-defined median depression, differing by the median depression being sub-triangular ( Fig. 17C, D ).

Labium brown, with sclerotized “pockets” on anterior region. Endites brown. Sternum yellow, with borders and anterior lateral excavations dark brown. Legs yellow, with posterior region of lateral surfaces of tibiae black. Abdomen dorsum yellow, with pair of longitudinal black spots in cardiac area; in median region, two pairs of black spots on each side; subsequently, one subrectangular black spot, yellow in middle.
