Genus Guadana Rheims, 2010a

Figs 1−57

Guadana Rheims, 2010a: 33 (Type species Guadana manauara Rheims by original designation).

Emended diagnosis. Species of Guadana Rheims resemble those of Sparianthina Banks 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); and male palps with a strong dorsal tegular apophysis (DTA) ( Figs 57−66 , 94−102 ); female palp with a long-toothed claw ( Jäger et al. 2009: figs 13, 64). They are distinguished from those of the latter genus by the male palps with DTA acutely tapering ( Figs 57−66 ); embolus with basal projection absent or at the prolateral side of the embolus ( Figs 67−76 ) (DTA roundly blunt or distally widened, basal projection at the retrolateral or ventral side of the embolus in Sparianthina ) and by the female vulva with glandular projection absent and fertilization ducts short (e.g., Figs 5 , 30 , 47 ) (glandular projection present and fertilization ducts long in Sparianthina ).

Description. See Rheims (2010a).
