Diagnosis
This species may be separated from other Charinus in eastern South America by means of the following combination of characters: cheliceral claw with eleven teeth; pedipalp coxa with three long setae on margin, and two distinct setae encircled by round carina; pedipalp tarsus with two subequal dorsal spines (Fig. 71C); leg IV basitibia trichobothrium bt situated proximal to submedial; distitibia trichobothrium bc situated closer to sbf than to bf, sc and sc series each with six trichobothria.
This species resembles C. imperialis sp. nov. but possesses more spines on the pedipalp. One specimen (MNRJ 9098) exhibits a spine between dorsal spines 1 and 2 of the femur and a series of three or four small spines parallel to the primary series of dorsal spines, the first spine situated between spines 1 and 2, the second spine ventral to spine 2, and the third between spines 3 and 4. These spines vary in number and position in other individuals. The male is unknown.
Etymology
Noun in apposition honoring the Puri indigenous tribe who originally inhabited the area where the type series was collected.

Description
CARAPACE. Six anterior setae (Fig. 71A); frontal process triangular. Small granules densely scattered between ocular triads and among sulci. Median eyes well developed (Fig. 71A); median ocular tubercle reduced, with pair of setae; lateral eyes well developed, seta posterior to lateral ocular triad; lateral ocular triad well separated from carapace margin.
STERNUM. Tritosternum projected anteriorly with typical setation, long, surpassing base of pedipalp coxae (Fig. 71B); other sternal platelets narrow and concave, with pair of setae anteriorly on plaque and some smaller setae posteriorly; pentasternum with eleven setae anteriorly and three setae near membranous region.
OPISTHOSOMA. Ventral sacs and ventral sac cover absent.
GENITALIA. Female genital operculum with prominent setae posteromedially and some smaller setae near margin (Fig. 72A–C); gonopod sucker-like and slightly sclerotized basally (Fig. 72A, D–E); conical, without constriction (Fig. 72A, D–E); smooth surface between gonopods and distal border of gonopod (Fig. 72B). Male unknown.
CHELICERAE. Small tooth projecting from retrolateral surface of basal segment, opposite to bifid tooth; retrolateral surface of claw with continous row of setae, basally to medially; claw with eleven teeth; row of eighteen setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp.
PEDIPALPS. Coxal dorsal carina with two prominent setae encircled by round carina and three setae on margin. Femur with four dorsal spines and five ventral spines (Fig. 71D); spine between dorsal spines 2 and 3, and spines 3 and 4; four prominent setiferous tubercles between dorsal spine 1 and proximal margin; ventral spine between spine 1 and proximal margin (Fig. 71E); small spine ventral to extra spine proximal to spine 1, near articulation between femur and trochanter; spine between ventral spines 1 and 2, two spines between spines 2 and 3, and between spines 3 and 4. Patella with six dorsal spines in primary series (Fig. 71E); prominent setiferous tubercle distal to spine I, one-third length of spine I; four or five ventral spines (Fig. 71F); prominent setiferous tubercle between spine I and distal margin; small spine between spines 2 and 3. Tibia with ventral spine distally and four setae between spine and distal margin. Tarsus with two dorsal spines, distal spine twice as long as proximal spine (Fig. 71C); cleaning organ with 27–29 setae in ventral row.
LEGS. Tibia of leg I with 23 articles; tarsus I with 41 articles; first tarsal article shorter than second article. Leg IV basitibia with four pseudo-articles, with sclerotized, denticulate margin projecting from apex of articles; basitibia trichobothrium bt situated proximal to submedial on pseudo-article; distitibia trichobothrium bc situated closer to sbf than to bf, sc and sf series each with six trichobothria.
