Diagnosis. Corresponding to C. caelatipennis angustatus in all diagnostic characters mentioned under that subspecies, but may be separated from it by the short, uniformly distributed strioles on the pronotal disc in both sexes. In addition, females of C. c. princeps often bear short strioles also on the basal third of the elytra.

Ecology. According to YOUNG (1963), C. caelatipennis princeps usually occurs only in clear, unpolluted water in the USA. In Cuba, the species was collected in temporary lentic environments with turbid water and muddy bottom, from lowlands up to 50 m a.s.l.

Distribution. In the USA known from New Jersey and Illinois to Florida and Texas ( LARSON et al. 2000). In Cuba, Copelatus caelatipennis princeps is recorded from both western (Isla de la Juventud) and eastern parts of the country (Guantánamo province) ( Fig. 26 ). This is the first record of this subspecies from the West Indies.
