Abstract:
A new genus of cavernicolous fresh-water palaemonid shrimp, Troglomexicanus, and two new species, T. tamaulipasensis and T. huastecae, are described from El Abra limestone caves in the states of San Luis Potosá½· and Tamaulipas, northeastern Mexico. Troglomexicanus includes T. perezfarfantae, formerly in the genus Troglocubanus, distributed also in El Abra limestone caves. The following characters shared by the 3 species support the creation of the new genus: rostrum without dorsal or ventral teeth, maxilla with single-lobed endite, bilobed epipodite of first maxilliped, second maxilliped without podobranch, and absence of antennal, hepatic, or branchiostegal spines of carapace. The maxilla with single-lobed endite and a bilobed epipodite of first maxilliped are two characters not shared with any other genus in the subfamily Palaemoninae.
