Diagnosis

Based on Giupponi & Miranda (2016), this species may be separated from other Charinus in Amazonia and northern South America by means of the following combination of characters: tegument pale yellow; cushion-like female gonopod with lateral projections directed posteriorly, covering opening of internal seminal receptacles (atrium); median and lateral eyes present, but median ocular tubercle and lateral eyes markedly reduced, as in C. carajas; median ocular tubercle situated in depression; small, rounded tetra- and pentasternum; weakly sclerotized margin of sternum; pedipalp femur with three dorsal spines; proximal spine of pedipalp tarsus ca one-quarter length of distal spine; tibia of leg I with 21 articles, tarsus I with 37 articles; leg IV basitibia with three pseudo-articles; leg IV basitibia trichobothrium bt situated in proximal third; leg IV distitibia with 16 trichobothria; leg IV distitibia bf, bc and sbf trichobothria equidistant; sc and sf series each with five trichobothria.
