(
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.

Costa Rica
