Abstract

A new species, Argulus yucatanus, is described based on 14 specimens from Cichlasoma urophthalmus collected in Celestun Lagoon, Yucatan, Mexico. Diagnostic characters include the number of and shape of sclerites in the suction cup support rods, shape of and position of respiratory areas, and modifications on the legs of males. In males, the coxae of the 2nd legs bear an angular lobe with 5–7 erect scales and 13–21 sensilla. The new species is compared to Argulus funduli Krøyer, 1863, A. chromidis Krøyer, 1863, A. cubensis Wilson, 1936, A. rhamdiae Wilson, 1936, and A. varians Bere, 1936.
