Genus Sparianthina Banks, 1929  

Sparianthina Banks, 1929: 80   (Type species Sparianthina selenopoides Banks   by original designation).

Emended diagnosis. Species of Sparianthina   resemble those of Guadana   in having intermarginal denticles arranged in a row; two pairs of ventral spines on tibiae I−II and one lateral spine on each side of metatarsi I−II (see Jäger et al. 2009: figs 10, 33; Rheims 2010a: fig. 7); male palps with a strong dorsal tegular apophysis (DTA) ( Figs 57−66 View FIGURES 57−66 , 94−102 View FIGURES 94−102 ); and female palps with a long-toothed claw ( Jäger et al. 2009: figs 13, 64). Males are distinguished from those of the latter genus by the palps with DTA roundly blunt, bifid, or widened at tip ( Figs 94−102 View FIGURES 94−102 ); and embolus with basal projection at the retrolateral or ventral side of the embolus ( Figs 103−111 View FIGURES 103−111 ) (DTA acutely tapering and embolus with basal projection absent or at the prolateral side of the embolus in Guadana   ). Females are distinguished by the epigyne with median septum smooth, without ledges or pockets ( Figs 83 View FIGURES 83−88 , 112−116 View FIGURES 112−116 ) (present in Guadana   ) and vulva bearing glandular projection and fertilization ducts long ( Fig. 84 View FIGURES 83−88 ; Jäger et al. 2009: figs 15, 29, 59; Rheims 2011: figs 5, 13) (glandular projection absent and fertilization ducts short in Guadana   ).

Distribution. Southern Central America and Northern South America, with records in Costa Rica, Panamá, Colombia, Venezuela and Trinidad & Tobago ( Figs 117−118 View FIGURES 117−118 ).

Composition. Ten species: Sparianthina adisi   ; S. boyaca   sp. nov.; S. deltshevi   ; S. gaita   ; S. milleri   ; S. parang   ; S. pumilla   ; S. saaristoi   ; S. selenopoides   ; S. soca   sp. nov.
