Diagnosis

This species may be separated from other Charinus in western South America by means of the following combination of characters: large size; pronounced pedipalps; median and lateral eyes well developed; median ocular tubercle shallow; female gonopod cushion-like; leg IV basitibia with four pseudo-articles.

Etymology

Patronym honoring Dr Hans-Wilhelm Koepcke ( Weygoldt 1972).

Supplementary description

CARAPACE. 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; pair of setae on median ocular tubercle; lateral eyes well developed, with seta posterior to lateral ocular triad.

STERNUM. Tritosternum projected anteriorly, with typical setation; other sternal platelets divided, concave, with seta on each side of platelets and smaller setae basally; pentasternum with four setae anteriorly and seta 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; gonopod cushion-like; gonopods sclerotized basally; rounded base with narrow, pointed apex. Male gonopod with base of fistula and lateral lobe sclerotized; lateral lobe 2 not fimbriate.

CHELICERAE. Small tooth projecting from retrolateral surface of basal segment, opposite to bifid tooth; retrolateral surface of claw without seta; claw with five teeth; transverse row of 6–8 setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp.

PEDIPALPS. Coxal dorsal carina without seta encircled by round carina and four setae on margin. Femur with three or four dorsal spines and three or four ventral spines; two prominent setiferous tubercles between dorsal spine 1 and proximal margin; spine between ventral spine 1 and proximal margin. Patella with four dorsal spines in primary series; prominent setiferous tubercle distal to spine I, one-third length of spine I; three ventral spines in primary series; prominent setiferous tubercle between spine I and distal margin. Tibia with ventral spine distally and seta between spine and distal margin. Tarsus with two dorsal spines, proximal spine half length of distal spine; cleaning organ with 24–30 setae in ventral row.

LEGS. Tibia of leg I with 23 articles (up to 31 in regenerated legs); tarsus I with 43 articles (up to 46 in regenerated legs); first tarsal article similar in length to subsequent articles. Leg IV basitibia with four pseudo-articles, without sclerotized, denticulate margin projecting from apex of articles; trichobothrium bt situated in proximal third of pseudo-article; distitibia trichobothrium bc situated closer to bf than to sbf (situated closer to sbf in one paratype), sc and sf series each with five trichobothria.
