Diagnosis

This species may be separated from other species of Charinus in Oceania by means of the following characters: carapace with black markings radiating from fovea, cheliceral claw with five teeth, patella with three ventral spines, median and lateral eyes well developed.

Etymology

Patronym honoring Stewart B. Peck (Weygoldt 2006).

Type material

Supplementary description

CARAPACE. Small granules densely scattered between ocular triads and among sulci. Median eyes and median ocular tubercle well developed; pair of setae on median ocular tubercle; lateral eyes well developed, seta posterior to lateral ocular triad; lateral ocular triad well separated from margin of carapace.

STERNUM. Tritosternum projected anteriorly with typical setation; other sternal platelets wide, with seta on each lateral border and some smaller setae posteriorly and in between; pentasternum with two setae anteriorly and one seta in membranous region.

OPISTHOSOMA. Ventral sacs and ventral sac cover absent.

GENITALIA. Posterior margin of female genital operculum slightly convex; gonopod cushion-like, unsclerotized basally. Male gonopod with border of fistula and lateral lobes 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 5 teeth; two rows of around eight setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp.

PEDIPALPS. Coxal dorsal carina with four setae encircled by round carina and four setae on margin. Femur with four dorsal spines and four ventral spines; spine between ventral spine 1 and proximal margin. Patella with three dorsal spines; prominent setiferous tubercle distal to spine I, one-third length of spine I; three ventral spines (holotype with two spines on dextral pedipalp); several setiferous tubercles between spine I and distal margin. Tibia with ventral spine distally, six long setae between spine and distal margin, and several setae throughout prolateral part of segment. Tarsus with two dorsal spines (holotype with three spines on dextral pedipalp), distal spine short, proximal spine one-third length of distal spine; several long, narrow setae ventral to distal spine; cleaning organ with 28–34 setae in ventral row.

LEGS. Tibia of leg I with 23 articles; tarsus I with 41 articles; first tarsal article similar in length to sum of subsequent 2–4 articles. Leg IV basitibia with four pseudo-articles, trichobothrium bt situated medially on pseudo-article; distitibia trichobothrium bc situated slightly closer to sbf than to bf, sc and sf series each with five trichobothria.
