Diagnosis

This species may be separated from other Charinus in eastern South America by means of the following combination of characters: median eyes well developed; female gonopod sucker-like, slightly sclerotized anteroventrally; male genitalia slightly sclerotized at base of fistula and lateral lobe; cheliceral claw with up to eight teeth; secondary sexual dimorphism, males larger than females, with elongation of pedipalps; pedipalp femur with five or six dorsal spines and four or five ventral spines in primary series, with small spine proximal to ventral spine 1; pedipalp patella with six or seven dorsal spines and four or five ventral spines; pedipalp tarsus with two small subequal dorsal spines, distal spine slightly longer than proximal spine; tibia of leg I with 23 articles, tarsus I with 41 articles; leg IV basitibia with four pseudo-articles; trichobothrium bc situated closer to sbf than to bf, sc and sf series each with six trichobothria.
