Haliotrematoides spp. (Monogenoidea: Dactylogyridae) infecting the gills of grunts (Perciformes: Haemulidae) from the southern coast of Quintana Roo, Mexico.

One previously described species, Haliotrema striatohamus Zhukov, 1981, found off the coast of Cuba and Campeche (Gulf of Mexico), is redescribed and transferred to Haliotrematoides Kritsky, Yang and Sun, 2009, as Haliotrematoides striatohamus ( Zhukov, 1981) n. comb. This transfer is based on the study of new specimens of this species found in the gill lamellae of grunts, i.e., Haemulon aurolineatum Cuvier, Haemulon plumierii (Lacepède), and Haemulon sciurus (Shaw) (Haemulidae), all from the southern coast of Quintana Roo, Mexico. In addition, another previously described species, Haliotrema brevispirocirrus Zhukov, 1981 from Haemulon striatum (Linnaeus) from Havana, Cuba, is also transferred to Haliotrematoides based on the comparative morphology of its original description. Data are provided for prevalence and mean intensity as well as for the morphologic and biometric variability of H. striatohamus from different hosts. The new replacement of H. striatohamus ( Zhukov, 1981) n. comb. and H. brevispirocirrus (Zhukov, 1981) n. comb. infecting these taxa represents the first known species of Haliotrematoides on these fishes and new geographical records for these dactylogyrid monogenoids.
