The Neotropical genera Guadana Rheims, 2010 and Sparianthina Banks, 1929 (Araneae: Sparassidae: Heteropodinae) Author Rheims, Cristina A. text Zootaxa 2021 2021-11-05 5061 3 401 431 journal article 3577 10.11646/zootaxa.5061.3.1 72f4b355-ff3e-4ca2-b6be-b6ef2b406c6c 1175-5326 5649711 14E73644-BF88-4999-887D-827553A372E1 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 , 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 ); and embolus with basal projection at the retrolateral or ventral side of the embolus ( Figs 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 , 112−116 ) (present in Guadana ) and vulva bearing glandular projection and fertilization ducts long ( Fig. 84 ; 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 ). 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.
