Diagnosis

This species may be separated from C. madagascariensis and other African species of Charinus by means of the following combination of characters: large size; tritosternum short, not reaching base of pedipalp coxae ( Fig. 90B View Fig ); pedipalp tarsus with three spines ( Fig. 90D View Fig ); tibia of leg I with 23 articles, tarsus I with 41 articles; leg IV basitibia with four pseudo-articles.

This species resembles C. africanus , but bears five teeth on the cheliceral claw, compared with six teeth in C. africanus , and a greater number of spines on the pedipalp.

Etymology

Noun in apposition honoring the Loko, an indigenous tribe that inhabit the Northern Province of Sierra Leone, particularly the Bombali and Port Loko Districts, and the vicinity of Freetown.

Description

CARAPACE. Lateral margin ventral to lateral eyes, markedly bent ventrally, creating appearance of projection of anterior carapace margin ( Fig. 90A View Fig ); six anterior setae ( Fig. 90A View Fig ); frontal process triangular ( Fig. 90C View Fig ). Small granules densely scattered between ocular triads and among sulci. Median eyes well developed ( Fig. 90C View Fig ); 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, short, only reaching base of pedipalp coxae ( Fig. 90B View Fig ); other sternal platelets narrow and concave, with pair of setae anteriorly on plaque and some smaller setae posteriorly; pentasternum with four setae anteriorly and without seta in 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. 91A–C View Fig ); gonopod cushion-like and sclerotized basally ( Fig. 91A–B, D–E View Fig ); apex of cushionlike gonopod serrated ( Fig. 91D–E View Fig ); slit sensilla on lateral margin of genital operculum ( Fig. 91F View Fig ). Male gonopod with apical border of fistula and lateral lobe sclerotized; LoL2 fimbriate and short ( Fig. 92A, D–E View Fig ); LoL1 well developed ( Fig. 92A, C View Fig ); LoD narrow, with denticulate surface ( Fig. 92B, E View Fig ).

CHELICERAE. Small tooth projecting from retrolateral surface of basal segment, opposite to bifid tooth ( Fig. 10B View Fig ); retrolateral surface of claw with continous row of setae, basally to medially ( Fig. 10B View Fig ); claw with five teeth ( Fig. 10A View Fig ); row of more than 20 setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp ( Fig. 10A–B View Fig ).

PEDIPALPS. Coxal dorsal carina with five or six prominent setae encircled by round carina and three setae on margin. Femur with four dorsal spines and four ventral spines ( Fig. 90E–F View Fig ); long spine between ventral spine 1 and proximal margin; three prominent setiferous tubercles between dorsal spine 1 and proximal margin. Patella with four long dorsal spines in primary series ( Fig. 90E View Fig ); prominent setiferous tubercle distal to spine I, half length of spine I; three ventral spines ( Fig. 90F View Fig ); prominent setiferous tubercle between spine I and distal margin. Tibia with ventral spine distally and two setae between spine and distal margin. Tarsus with three dorsal spines, spine 1 long, one-third length of tarsus, spine 2 aligned with and half length of spine 1 ( Fig. 90D View Fig ); spine 3 one-third length of spine 2 and situated near its base; cleaning organ with 22–24 setae in ventral row.

LEGS. Tibia of leg I with 23 articles; tarsus I with 41 articles; first tarsal article similar in length to subsequent article. Leg IV basitibia with four pseudo-articles, with sclerotized, denticulate projection at apex of articles; trichobothrium bt situated submedially on pseudo-article; leg IV distitibia trichobothrium bc situated closer to sbf than to bf, sc and sf series each with five trichobothria.
