TL;DR: Seasonal occurrence of parasitic copepods in wild bullseye puffer, Sphoeroides annulatus (Pisces: Tetraodontidae), was analyzed in conjunction with variation of biotic and abiotic factors and a significant positive association was detected between number of individuals and water temperature and between host size and both species richness and number of individual.
Abstract: Seasonal occurrence of parasitic copepods in wild bullseye puffer, Sphoeroides annulatus (Pisces: Tetraodontidae), was analyzed in conjunction with variation of biotic and abiotic factors. Eleven samples were taken between February 2007 and February 2008 in Santa Maria La Reforma lagoon (northwestern coast of Mexico). In total, 337 fish was examined; 5 parasitic copepod species were observed, including Acantholochus zairae, Caligus serratus, Lepeophtheirus simplex, Pseudochondracanthus diceraus, and Parabrachiella sp. The most common species were L. simplex, P. diceraus, and C. serratus (overall prevalence, 59, 53, and 35%, respectively), which significantly varied in prevalence and mean intensity between sampling months. A seasonal pattern was only observed for L. simplex, with higher infection levels in the warmest month than in the coldest month. Statistical analyses indicated that the intensity of L. simplex was positively correlated with water temperature. There were no significant differe...

TL;DR: A new species of Acantholochus Cressey, 1984 (Copepoda: Bomolochidae) parasitic on the gills of common snook, Centropomus undecimalis, from the coastal zone of the State of Rio de Janeiro, Brazil, is described and illustrated.
Abstract: A new species of Acantholochus Cressey, 1984 (Copepoda: Bomolochidae) parasitic on the gills of common snook, Centropomus undecimalis, from the coastal zone of the State of Rio de Janeiro, Brazil, is described and illustrated. The new species differs from all other species of Acantholochus by the presence of only one inner seta on middle segment of the second and third endopods.

TL;DR: It is suggested that species of the genus Acantholochus can only be distinguished from those of the genera Hamaticolax by the absence of the accessory process of the maxillipedal claw.
Abstract: A new bomolochid copepod species, Acantholochus zairae (Cyclopoida: Bomolochidae), was found on the bullseye puffer fish Sphoeroides annulatus (Jenyns). It is the ninth species belonging to Acatholochus Cressey around the world and the third from the Mexican Pacific. Females of A. zairae sp. n. can be distinguished from Acantholochus spp. mainly by the presence of one seta (instead of two) on the second endopodal segment of leg 2 and by the strong, large claw of the maxilla. Acantholochus zairae sp. n. is attributable either to Acantholochus or to Hamaticolax Ho & Lin since no useful character to distinguish the genus Acantholochus from the genus Hamaticolax was found in the literature. We therefore suggest that species of the genus Acantholochus can only be distinguished from those of the genus Hamaticolax by the absence of the accessory process of the maxillipedal claw. Due to the above, three species of bomolochids hitherto placed in the genus Acantholochus [H. galeichthyos (Luque & Bruno) comb. nov., H. paralabracis (Luque & Bruno) comb. nov. and H. unisagittatus (Tavares & Luque) comb. nov.] are transferred to Hamaticolax and three species hitherto placed in the genus Hamaticolax [A. albidus (Wilson) comb. nov., A. australiensis (Byrnes) comb. nov. and A. venustus (Kabata) comb. nov.] are transferred to Acantholochus. In addition, keys to the females of both genera are provided.

TL;DR: Two new species of the genus Acantholochus (Bomolochidae), from Peruvian waters are described and illustrated; A. galeichthyos and A. paralabracis parasites of the teleost fishes.
Abstract: Two new species of the genus Acantholochus (Bomolochidae), from Peruvian waters are described and illustrated; A. galeichthyos and A. paralabracis parasites of the teleost fishes Galeichthys peruvianus L. (Ariidae) and Paralabrax humeralis (V.) (Serranidae), respectively. Acantholochus galeichthyos sp. nov. differs from all other species of the genus by bearing two setae on the last endopod segment of leg 4. A. paralabracis sp. nov. can be distinguished from the other species of the genus by the absence of spinules on the abdominal segments and caudal rami.

TL;DR: A new species of Acantholochus Cressey, 1984 (Cyclopoida, Bomolochidae), parasitic on the gills and opercular cavity of the barred grunt Conodon nobilis, from the coastal zone of the State of Rio de Janeiro, Brazil, is described and illustrated.
Abstract: A new species of Acantholochus Cressey, 1984 (Cyclopoida, Bomolochidae), parasitic on the gills and opercular cavity of the barred grunt Conodon nobilis (Linnaeus, 1758), from the coastal zone of the State of Rio de Janeiro, Brazil, is described and illustrated. The new species differs from its congeners through a combination of characters that includes presence of lamellae on the spines on the third segment of the exopods of the third leg, the number of antennule segments, and the presence of one seta on the second endopodal segment of the third leg.
