Etymology. The specific epithet refers to a ritual tribute to the illustrious dead celebrated by the indigenous people of the Xingu.

Diagnosis. Males of Camillina kuarup resemble those of C. tarapaca Platnick & Shadab, 1982 , by the shape of the embolus, but differ from the last by a larger retrolateral tibial apophysis and a robuster U-shaped spermatic duct positioned along the border of the tegulum ( Figs 10–12 ; 44–49 ), while in C. tarapaca the duct has a sinuous loop in the prolateral portion of the tegulum, and the retrolateral tibial apophysis has a narrower tip (see Platnick & Shadab, 1982: figs 91, 92). Females resemble those of C. tarapaca , by the position of the secondary spermathecae, but differ from the last by a longer and wider median field with shorter copulatory ducts and a larger spermathecae relative to the median field width which are also located closer to the median field ( Figs 13–14 ; Platnick & Shadab, 1982: figs 93, 94).
