Diagnosis

This species may be separated from other Charinus in eastern South America by means of the following combination of characters: tegument covered with clavate setae; carapace and legs dark in color; leg I tarsus I with 23–28 articles with length of first tarsal article equal to combined length of subsequent ten articles.

Etymology

Although unspecified by the author, the name is a Latin adjective meaning ‘of mountains’, which refers to the occurrence of this species in a hilly landscape.

Supplementary description

CARAPACE. Tegument covered with short, broad setae. Six anterior setae; frontal process triangular, not visible in dorsal view. Small granules densely scattered between ocular triads and among sulci.

Median eyes present; median ocular tubercle shallow, with pair of setae. Lateral eyes well developed, seta posterior to lateral ocular triad.

STERNUM. Tritosternum projected anteriorly, with typical setation; other sternal platelets wide, flat, with pair of setae on each side of platelets and some smaller setae posteriorly; pentasternum with four setae anteriorly and three setae on membranous region.

OPISTHOSOMA. Ventral sacs and ventral sac cover absent.

GENITALIA. Female genital operculum with prominent setae posteromedially and some smaller setae near margin; posterior margin of genital operculum with pair of lateral sulci; gonopod sucker-like, funnel-shaped [dissected gonopod of female (MNRJ 9087) with sulcus on anterior side, as illustrated by Weygoldt (1972b) in original description of C. brasilianus ]; base of gonopods unsclerotized. Male gonopod with base of fistula and lateral lobe sclerotized; lateral lobe 2 fimbriate.

CHELICERAE. Small, flat tooth on retrolateral surface of basal segment, opposite to bifid tooth; retrolateral surface of claw with row of setae basally to medially; claw with seven teeth; transverse row of around seven setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp.

PEDIPALPS. Coxal dorsal carina with prominent seta encircled by round carina and three setae on margin. Femur with four dorsal spines and three ventral spines; three prominent setiferous tubercles between dorsal spine 1 and proximal margin; setiferous tubercle between ventral spine 1 and proximal margin. Patella with five dorsal spines in primary series; prominent setiferous tubercle distal to spine I, one-third length of spine I; four ventral spines in primary series; prominent setiferous tubercle between spine I and distal margin. Tibia with ventral spine distally and two setae between spine and distal margin. Tarsus with two dorsal spines, proximal spine half length of distal spine; cleaning organ with 26–28 setae in ventral row.

LEGS. Tibia of leg I with 23 articles; tarsus I with 28 articles; length of first tarsal article equal to combined length of subsequent ten articles. Leg IV basitibia with four pseudo-articles, without sclerotized, denticulate margin projecting from apex of articles; trichobothrium bt situated in distal third of pseudo-article; distitibia trichobothrium bc situated closer to sbf than to bf, sc and sf series each with six trichobothria.
