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 10–12View FIGURES 8–14; 44–49View FIGURES 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 13–14View FIGURES 8–14; Platnick & Shadab, 1982: figs 93, 94).

Description. Male (Holotype). Carapace brown with darker stripes, convergent and not continuous in the direction of the thoracic groove ( Fig. 8View FIGURES 8–14); thoracic groove dark brown ( Fig. 8View FIGURES 8–14); chelicerae brown ( Fig. 8View FIGURES 8–14) with fangs that are pale brown with dark brown laterals. Endites pale brown with apex pale yellow. Labium brown. Sternum orange with brown margins. Trochanters and coxae orange; femora, patellae and tibiae I and II dark brown; femora, patellae and tibiae III and IV mostly dark brown, with orange parts; metatarsi and tarsi orange. Abdomen dark gray with scutum brown, venter gray. Epigastric area yellowish on the sides and pale brown in the middle. Two parallel horizontal black spots interrupted in the middle close to the spinnerets. Carapace suboval, cephalic region narrower, and posterior region truncate ( Fig. 8View FIGURES 8–14).
