Description CARAPACE. Frontal process well developed, much wider than long, with blunt, rebordered or acute apex (Figs 42 C, 54 C). Carapace dorsoventrally compressed, wider than long. Median eyes and ocular tubercle or, when tubercle absent, anterior depression, leading to narrow medial sulcus that extends around posterior area of pair of lateral humps situated behind lateral eyespots (Fig. 35 A). Anterior margin rounded with fine setae and corners slightly depressed; with 6 – 10 small setae, two medial setae usually directly anterior to median ocular tubercle (Fig. 37 A). Carina originating at anterolateral margin, widening posteriorly from coxa I and onwards, widest dorsal to coxae III and IV, and reaching posterior margin. Many tiny punctations, more abundant in anterior area (Fig. 33 A), arranged in lines and spots, irradiating from fovea and interspersed with glabrous areas. Three pairs of deep sulci and very deep, rectangular or triangular fovea (corners form starting point of second and third sulci). First pair of sulci situated slightly posterior to lateral boss and not reaching midline. Four pairs of lateral depressions (first placed over first pair of sulci). Lateral eyes well developed, or reduced to small, whitish spot, without cornea or clearly defined lens (only small roundish knob), rarely absent. STERNUM. Four-segmented, all platelets sclerotized and convex (Fig. 31 B). Tritosternum with round base, projected anteriorly into long or small, blunt tubercle, with two apical setae and two basal setae (Fig. 24 B). Medial platelet (tetrasternum) rounded, convex, with two setae and few setulae; formed by single (Fig. 30 B) or paired (Fig. 24 B) platelets. Third platelet (pentasternum) also rounded and convex, but smaller, with shorter setae than second platelet; formed by single (Fig. 30 B) or paired (Fig. 24 B) platelets. Metasternum paired in anterior half, with anterior setae in membranous region followed by two or three setae in sclerotized area, arranged in longitudinal row from unsclerotized to sclerotized region; distal border with small elevation bearing 2 – 8 large setae. Sternites separated from each other by twice diameter of medial platelet. OPISTHOSOMA. Oblong, with almost indistinguishable punctations, finer than on carapace (Fig. 30 A). GENITALIA. Female gonopods rounded or oval, sucker-like (barrel shaped), with rounded opening (Fig. 65), finger-like (in C. africanus Hansen, 1921 only) or cushion-like, with wide atrial opening or covered with claw-like projection (Fig. 22). Male gonopods slightly wider than long, soft, only posterolateral margin of dorsal lobes and basal sclerite of lateral lobes sclerotized; median lobes long and thin, lamellar, with wide, rounded tip, almost reaching apex of lateral lobes (Fig. 25). CHELICERAE. Cheliceral furrow with four prolateral teeth (Fig. 10), distal tooth bifid. Fourth tooth twice as long as others and much stouter. Tooth length (from tip to base) IV> Ia> Ib = II> III. Claw with 5 – 13 denticles (Fig. 11 A – B, E – F). PEDIPALPS. Coxa with dorsal carina rounded in shape; 2 – 5 equidistant setae along prolateral margin, and 0 – 6 setae encircled by round carina. Trochanter with large distal, spiniform, ventral apophysis, bearing many prominent setae, and with blunt apex pointed anteriorly, and two subequal spines, one in median third and other at distal apex of prolateral surface (Fig. 2). Femur with 2 – 7 dorsal spines in primary series, decreasing in size, sometimes with secondary row of spines (Fig. 3 A – D); femur dorsal surface with row of 2 – 4 setiferous tubercles between spine 1 and proximal margin of segment; 2 – 6 ventral spines in primary series, sometimes with secondary row of spines; setiferous tubercle or spine between spine ventral 1 and proximal margin, aligned with primary series or displaced dorsally. Patella with 3 – 6 dorsal spines in primary series, decreasing in lengths (Fig. 4 A – D); small setal tubercle between spine I and distal margin of patella; 2 – 6 ventral spines, distal larger; 1 – 4 setiferous tubercles or 1 – 2 spines between ventral spine I and distal margin. Tibia with two dorsal spines, distal at end of proximal half, proximal in proximal third (Fig. 30); ventral spine in distal half, around two-thirds length of tibia, and 2 or 3 setal tubercles proximal to spine; row of 2 – 5 long, thin setae (longer than others in vicinity). Tarsus with 1 – 3 curved spines in proximal half (Figs 13, 52 D); cleaning organ about half article length of tarsus. Claw (apotele) with long, acute, curved apex. LEGS. All very setose. Femur length on leg I> III> IV> II; ventral corner of prolateral surface of leg II – IV femora projecting into distinct spiniform process. Tibia of leg I with 16 – 25 articles (up to 47 in regenerated legs); distal articles of tibia each with two small trichobothria, one on dorsal and one on prolateral side of article; one trichobothrium on second, third and fourth (from distal to proximal) articles, close to distal border, all situated dorsally; no trichobothria on other articles. Leg I tarsus (basitarsus + distitarsus) with 23 – 43 articles (up to 62 in regenerated legs); apical article with claw, tarsal organ and rod sensilla (Fig. 16).

Diagnosis Charinus may be distinguished from the other two genera of Charinidae by the following combination of characters: lateral eyes situated at least three times diameter of one ocellus from carapace lateral margin, with seta posterior to lateral ocular triad (Fig. 37 A – B); setiferous tubercles situated far apart on dorsal carina of pedipalp coxa; female gonopod cushion-like (Figs 5 C – D, 7 C – D), finger-like or suckerlike (Figs 5 A – B, 7 A – B); posterior margin of female genital operculum straight or rounded (Fig. 17); area of genital operculum between gonopods and posterior margin smooth in dorsal view (Fig. 17). Unlike Charinus, in which the area of genital operculum between the gonopods and posterior margin is smooth, and the posterior margin curved dorsally, the area has denticulate projections in Sarax (Figs 106 D, 113 D), and the posterior margin is linear in Weygoldtia.

Remarks Twelve species previously assigned to Charinus are hereby transferred to Sarax based on the phylogeny of Miranda et al. (2021). Those species share with other species of Sarax the position of the lateral eyes situated near the carapace margin, the finger-like and plunger-like shape of the female gonopod, and the similar shape of the posterior margin of the genital operculum with denticulated surface on the dorsal area and ventral projections aligned with the gonopods. Key to the identification of the species of Charinus in the Caribbean and Central America

Distribution Recorded from the following countries and territories: Australia, Belize, Brazil, Colombia, Cuba, Dominican Republic, Ecuador, Equatorial Guinea, French Guiana, Ghana, Guadeloupe, Guinea, Guiana, Jamaica, Kenya, Madagascar, Martinique, New Caledonia, Panama, Papua New Guinea, Puerto Rico, Saint-Barthélemy, Samoa, São Tomé and Príncipe, Sierra Leone, Surinam, US Virgin Islands, Venezuela.

Etymology Unknown, but likely to be the diminutive of the name Charon.
