To date, only one species of Leptochelia Dana, 1849 has been described from the Cuban archipelago, L. tenuicula Makkaveeva, 1968, and two others have been recorded, L. forresti (Stebbing, 1896) and L. savignyi (Krøyer, 1842). From new collections in the area, herein two new species are described, L. ortizi n. sp. and L. pinarensis n. sp. Males of L. ortizi are distinguished by the possession of two small, unequal medial processes on the cutting edge of the cheliped fixed finger, and six spiniform setae on the inner margin of the dactylus. Females bear an inner row of fine setules on the lacinia mobilis of the left mandible. Likewise, females of L. pinarensis are recognized by having two plumose setae on the inner margin of the fourth article of the maxilliped. The addition of these two species increases the number of species of the genus in Cuba to five.
