Abstract

and Previous to this study, the palaemonid genus Troglocubanus Holthuis, 1949, included six species: four distributed in Cuba [T. eigen- manni (Hay, 1903), T. gibarensis (Chase, 1943), T. inermis (Chase, 1943), and T. cal- cis (Rathbun, 1912)], one in Jamaica (T. ja- maicensis Holthuis, 1963), and one in Mex- ico (T. perezfarfantae Villalobos, 1971). Troglocubanus as proposed by Holthuis (1949), included troglobitic species, unpig- mented, with reduced eyes lacking a cornea, a carapace without hepatic or branchiostegal spines, and a mandible without a palp. Vari- able characters within the genus were the ros- trum, which could be short and smooth or well developed with many dorsal teeth, the presence or absence of an antennal spine, the endite of the second maxilla which is bilobed in the Antillean species and single-lobed in the Mexican species, and the epipodite of the first maxilliped which is bilobed in the Mex- ican species. These important differences, arising between the Mexican T. perezfarfan- tae and the Antillean species, were recog- nized and discussed by Villalobos (1971).
