This species may be separated from other Charinus in western South America by means of the following combination of characters: four anterior setae on carapace ( Fig. 42A View Fig ); median eyes absent ( Fig. 42A, C View Fig ); bifid tooth of basal segment with ventral cusp larger than dorsal cusp ( Fig. 10E–F View Fig ); leg IV basitibia with two pseudo-articles.


Noun in apposition taken from the type locality.

Type material

Holotype COLOMBIA • ♀; Putumayo Department, Mocoa ; [01°09′08.42″ N, 76°39′03.8″ W]; 21 Jul. 1956; H. Sturm leg.; SMF 68 View Materials . GoogleMaps


CARAPACE. Four anterior setae ( Fig. 42A View Fig ); frontal process triangular, not visible in dorsal view ( Fig. 42C View Fig ). Small granules densely scattered between ocular triads and among sulci. Median eyes and median ocular tubercle absent ( Fig. 42C View Fig ); pair of setae in place of median eyes; lateral eyes reduced, pale, seta posterior to lateral ocular triad.

STERNUM. Tritosternum projected anteriorly, with typical setation ( Fig. 42B View Fig ); other sternal platelets divided into two, with acuminate setae anteriorly on each platelet and some smaller setae posteriorly ( Fig. 42B View Fig ); pentasternum with six setae anteriorly and two setae near membranous region.

OPISTHOSOMA. Ventral sacs and ventral sac cover absent.

GENITALIA. Female genital operculum with prominent setae posteromedially and smaller setae near margin ( Fig. 5G–H View Fig ); posterior margin of genital operculum with pair of shallow lateral sulci ( Fig. 5G– H View Fig ); gonopod cushion-like; base of gonopods slightly sclerotized ( Fig. 5G–H View Fig ). Male unknown.

CHELICERAE. Small, flat tooth on retrolateral surface of basal segment, opposite to bifid tooth ( Fig. 10F View Fig ); retrolateral surface of claw with row of setae from base to midline; claw with five teeth ( Fig. 10E–F View Fig ); transverse row of five setae on prolateral surface of basal segment; bifid tooth of basal segment with ventral cusp larger than dorsal cusp ( Fig. 10E–F View Fig ).

PEDIPALPS. Coxal dorsal carina with four setae encircled by round carina and three setae on margin. Femur with three dorsal spines and three ventral spines ( Fig. 42E–F View Fig ); two prominent setiferous tubercles between dorsal spine 1 and proximal margin; setiferous tubercle between ventral spine 1 and proximal margin. Patella with three dorsal spines in primary series ( Fig. 42E View Fig ); prominent setiferous tubercle distal to spine I, one-third length of spine I; two ventral spines in primary series; setiferous tubercle between spine I and distal margin. Tibia with ventral spine distally and four setae between spine and distal margin. Tarsus with two dorsal spines, distal spine half length of tarsus and proximal spine one-third length of distal spine ( Fig. 42D View Fig ); cleaning organ with 28–33 setae in ventral row.

LEGS. Leg IV basitibia with two pseudo-articles, without sclerotized, denticulate margin at apex of articles; trichobothrium bt situated in proximal third of pseudo-article; distitibia with trichobothrium bc situated closer to sbf than to bf, sc and sf series each with five trichobothria.

Armas et al. (2012) recorded several juveniles and/or poorly preserved specimens of Charinus from different localities in Colombia and provided photographs of the first charinid specimens recorded from the country. Armas et al. (2012) could not precisely identify the Charinus species due to the poor preservation of the material, and suggested the specimens resembled C. acosta . The specimen from the Sucre Department was excluded from the map because a precise locality was unavailable. However, C. rocamadre is also known from Sucre and differs from C. acosta in the development of the median eyes, which are absent in C. rocamadre , but present (although reduced) in C. acosta .
