Diagnosis

This species may be separated from C. madagascariensis and other African species of Charinus by means of the following combination of characters: secondary sexual dimorphism, males with longer pedipalp segments than females; cheliceral claw with four teeth; female gonopod cushion-like; three spines on pedipalp tarsus.

Etymology

Patronym honoring J. Millot ( Fage 1939).

Type material (examined)

Syntypes GUINEA • 1 ♂ [chelicerae missing], 1 ♂ [opisthosoma missing, but pedipalps suggest ad. ♂], 1 ad. [gonopods and pedipalps missing], 2 subad. [opisthosoma missing], 1 juv. [opisthosoma missing]; Grotte Tinka, Grotte Dalaba; Millot leg.; MNHN .

Redescription

CARAPACE. Six short anterior setae ( Fig. 93A View Fig ); frontal process triangular. Small granules densely scattered between ocular triads and among sulci. Median eyes and median ocular tubercle reduced ( Fig. 93A View Fig ); pair of setae on median ocular tubercle; lateral eyes reduced, pale, 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. 93B View Fig ); other sternal platelets narrow, 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 gonopods cushion-like. Male gonopods unknown (could not be studied due to poor preservation).

CHELICERAE. Large tooth projecting from retrolateral surface of basal segment, opposite to bifid tooth ( Fig. 11B View Fig ); retrolateral surface of claw with discontinous row of setae, basally to medially; claw with four teeth ( Fig. 11A–B View Fig ); row of twelve setae on prolateral surface of basal segment; bifid tooth on basal segment with dorsal cusp larger than ventral cusp ( Fig. 11A–B View Fig ).

PEDIPALPS. Coxal dorsal carina with six prominent setae encircled by round carina and two setae on margin. Femur with four dorsal spines and five ventral spines ( Fig. 93C–D View Fig ); small spine between each dorsal spine; small spine between ventral spines 1 and 2, and spines 2 and 3 (large setiferous tubercle between spines 1 and 2 in smaller specimen without gonopod); long spine proximal to ventral spine 1; long setiferous tubercle ventral to spine 1; three prominent setiferous tubercles between dorsal spine 1 and proximal margin. Patella with three long dorsal spines in primary series and row of 3–5 small spines, slightly longer than setiferous tubercle ( Fig. 93C View Fig ); long setiferous tubercle between spines 1 and 2; prominent setiferous tubercle distal to spine I, half length of spine I; three ventral spines with small spine between each ( Fig. 93D View Fig ); large setiferous tubercle between spine I and distal margin. Tibia with one ventral spine distally and three or four setae between spine and distal margin ( Fig. 93D View Fig ). Tarsus with three dorsal spines, spine 1 long, half length of tarsus, spine 2 aligned and half length of spine 1, spine 3 one-third length of spine 2 and situated near its base ( Fig. 93C View Fig ); cleaning organ with 25–28 setae in ventral row.

LEGS. Tibia of leg I with 23 articles; tarsus I with 43 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 in distal third of pseudo-article; distitibia trichobothrium bc situated closer to sbf than to bf, sc and sf series each with five trichobothria.
