This species may be separated from other Charinus in eastern South America by means of the following combination of characters: large size; cheliceral claw with 13 teeth; pedipalp coxae with seven setae encircled by dorsal rounded carina; secondary series of spines on pedipalp segments present ( Figs 3A– B View Fig , 49E View Fig ); distitibia of leg IV with sc and sf with six trichobothria.

The presence of seven setae encircled by the dorsal rounded carina of the coxa is otherwise observed only in C. goitaca sp. nov., from which C. carinae sp. nov. differs in the greater number of ventral spines on the pedipalp patella, i.e., six spines in C. carinae sp. nov. compared with three or four spines in C. goitaca sp. nov., and the greater number of cheliceral teeth, i.e., ten in C. carinae sp. nov. compared with thirteen in C. goitaca sp. nov.


This species is a patronym honoring Carine C. Gonçalves Galvão for her immeasurable support to the first author during the preparation of this work.

CARAPACE. Frontal process large, subtriangular, not visible in dorsal view ( Fig. 49C View Fig ); median eyes and median ocular tubercle present ( Fig. 49A, C View Fig ); median ocular tubercle shallow, slightly higher than carapace surface, with pair of small setae ( Fig. 49C View Fig ); lateral eyes well developed, pale, small seta posterior to each lateral ocular triad ( Fig. 49A View Fig ); lenses directed anteriorly and dorsally.

STERNUM. Tritosternum projected anteriorly into blunt tubercle, surpassing base of pedipalp coxae ( Fig. 49B View Fig ); medial platelet (tetrasternum) and third platelet (pentasternum) with single convex platelet, with pair of large setae anteriorly, and several small setae posteriorly; metasternum with five large setae anteriorly at margin between membranous and sclerotized regions, and longitudinal row of several small setae, from anterior to posterior ( Fig. 49B View Fig ); four to six setae in posterior area.

OPISTHOSOMA. Ventral sacs and ventral sac cover absent.

GENITALIA. Male gonopod rectangular ( Fig. 50C View Fig ); LoL2 fimbriate with long projections ( Fig. 50B, D View Fig ); LoL1 acute, with spine-like projections ( Fig. 50E View Fig ); LaM long and thin, surpassing lateral lobes ( Fig. 50A–B View Fig ); fistula with small globular projection ventrally ( Fig. 50F View Fig ). Female unknown.

CHELICERAE. Small tooth in retrolateral row of basal segment; prolateral surface with transverse row of around eight small setae, from ventral to dorsal surface; three setae at dorsodistal margin, prolateral, retromedial and retrolateral, near membranous region of claw; claw with thirteen teeth and row of setae on retrolateral surface from base to near apex (dorsal side).

PEDIPALPS. Coxal rounded carina enclosing two to five small setae, and with four to five setae on anterior margin. Femur with three distinct setiferous tubercles proximal to spine 1 ( Figs 3A–B View Fig , 49E View Fig ); primary series with five dorsal spines, with smaller spine between spines 3 and 4, and another smaller spine between spines 4 and 5 ( Figs 3A–B View Fig , 49E View Fig ); five ventral spines, small spine between spines 1 and 2, two small between spines 2 or 3, and small spines between spines 3 and 4, and spines 4 and 5 ( Fig. 49F View Fig ); additional spine, situated prolateral to primary series, between spines 1 and 2; large spine proximal to ventral spine 1, with small spine near its base. Pedipalp patella with six dorsal spines ( Figs 4A–B View Fig , 49E View Fig ); large setiferous tubercle distal to spine I, about one-third length of spine I ( Fig. 4A–B View Fig ); six ventral spines; small spine between spines II and III; two to five setiferous tubercles between spine I and distal margin. Tibia with two dorsal spines, proximal spine two-thirds length of distal spine; ventral spine situated in distal half of tibia; three long setae between spine and distal margin. Tarsus with three dorsal spines, two distal spines subequal and one-fifth length of tarsus ( Fig. 49D View Fig ); proximal spine smaller, ca one-third length of other two spines, situated closer to large proximal spine and with long setae at its base; ventral row of cleaning brush with 27–29 setae.

LEGS. Tibia of leg I with 23 articles (up to 29 articles on regenerated legs), tarsus I with 41 articles (up to 49 on regenerated legs); tarsal organ situated close to base of claw ( Fig. 51A–B View Fig ); rod sensilla with six setae in shallow groove ( Fig. 51C View Fig ). Leg IV basitibia with four pseudo-articles; trichobothrium bt situated in proximal third; distal apex of basitibial pseudo-articles with dark, denticulate projection;

distitibia trichobothrium bc situated closer to sbf than to bf; sc and sf series each with six trichobothria; distitarsus with distinct white annulus distally on first article.
