Etymology: The specific epithet xinguensis refers to the type locality of this species in Vitória do Xingu, Pará, Brazil. Xingu is an indigenous word meaning good and clean water.

Distribution: This species is limited in the north by the Amazonas River, in the east by the Xingu River and in the west by the Madeira River. The southern limit is unknown ( Fig. 27).

Diagnosis: Dorsal coloration grey, yellow on the rump and venter pale yellowish. Legs and tail are grey. Dorsal stripe clearly marked and evident, ventral stripe indistinct and irregular. Fronto-nasal region of the skull not depressed, with a straight profile. External aperture of the ear directed laterally. Naso-maxillary sutures approximately parallel, with a wide fronto-maxillary suture. Fronto-parietal with a triangular shape, pterygoid bone overlaps tympanic bulla.

Comparisons: Cyclopes xinguensis is mostly grey, unlike most of the other species of Cyclopes . Its colour is somewhat similar to C. ida , but the rump is yellowish in C. xinguensis and completely grey in C. ida . Also, C. ida lacks a dorsal stripe, which is very evident in C. xinguensis .
