Diagnosis
: Specimens of
L. cubana
resemble those of
L. caribbaea
by the length of the palpal tibiae in the male palp, but can be distinguished by a straight embolus longer than the width of the bulb (figs. 9−10) and by the receptacles of epigynum with two lobes, of which the inner one is just a quarter or less longer than the outer and enlarged at end, coming out from an enlarged base (
Figs. 39−40
).
