Diagnosis. Specimens of L. caribbaea  resemble those of L. cubana  by the length of the palpal tibiae in the male palp, but can be distinguished by a curved embolus longer than the width of the bulb in males (figs. 1−2) and by the receptacles of epigynum with two lobes, of which the inner one is coming out from the outer one and is enlarged at end, both lobes on a short base ( Figs. 41−42View FIGURES 39 − 44).
