The ecology, distribution, and taxonomy of bopyrid isopod species are often omitted from studies not systematically addressed to crustaceans. From a wider study of zooplankton in coastal and reef waters of the Mexican Caribbean Sea, two bopyrid species were collected, Probopyrinella latreuticola, attached to the branchial chamber of Latreutes fucor...
Based on the examination of diverse crustacean taxa collected along the Mexican Pacific and deposited in the Colección Nacional de Crustá- ceos of the Instituto de Biología, UNAM, six spe- cies of bopyrid isopods were detected. New hosts and localities are reported for Munidion pleuroncodis Markham, 1975, Probopyrus pacificensis Román- Contreras, 1...
Six species of bopyrids were detected from the examination of hermit crabs collected along the Atlantic coasts of Mexico and deposited in the Colección Nacional de Crustáceos housed at the Universidad Nacional Autónoma de México. Asymmetrione tuxtlaensis sp. nov., the third species of the genus from the west Atlantic, is described. The occurrence o...
Six species of bopyrids were detected by inspection of crustaceans of diverse taxa collected in the Gulf of Mexico and the Mexican Caribbean that were deposited in two scientific collections housed in the Universidad Nacional Autónoma de México. Probynia ramiroromani, new species is described, becoming the first species of the genus from the Americ...
Robinione overstreeti is a bopyrid isopod endemic to the Gulf of Mexico that inhabits the branchial chamber of the ghost shrimp Callichirus islagrande. Information on this host–parasite association is scant. This study describes population and reproductive features of R. overstreeti and its host. A total of 90 (9.97%) out of 903 individuals of C. i...
Based on the examination of alpheid shrimps from the SW Gulf of Mexico and the Mexican Caribbean, deposited in two scientific collections housed in the Universidad Nacional Autónoma de México, we document for the first time Synalpheus curacaoensis, Alpheus cristulifrons and A. estuariensis as hosts of bopyrid isopods, and for the latter alpheid spe...
Two bopyrid species parasitizing shrimps of the genus Thor along the Mexican coasts of the Gulf of Mexico and Caribbean Sea are known: Bopyrinella thorii, attaching in the hosts’ branchial chambers, and Loki circumsaltanus, attaching to the hosts´ abdomens. Herein, Bopyrinella hadrocoxalis sp. nov. is described, becoming the second described specie...
This study explored the population biology and reproduction of Tozeuma carolinense in Laguna de Términos, Campeche, southwestern Gulf of Mexico, collected bimonthly from June 2009 to June 2010. The sample of 2,109 specimens analysed had a sex ratio of 0.39 males per female. On average, females were significantly larger (6.16 ± 2.02 mm carapace leng...
Based on examination of porcellanid crabs from the Gulf of California, Mexico, deposited in the Colección Nacional de Crustáceos of the Instituto de Biología, Universidad Nacional Autónoma de México, we document Petrolisthes crenulatus, P. hirtispinosus and P. galapagensis as hosts of bopyrid isopods belonging to the genus Aporobopyrus for the firs...
This is only the second report of the bopyrid isopod Parabopyrella thomasi (Nierstrasz & Brender à Brandis, 1929) since it was described. The species infests the arrow shrimp Tozeuma carolinense Kingsley, 1878, and this report of new material extends its known geographic distribution to the Caribbean coasts of Mexico. We provide data on some morpho...
The purpose of this study was to describe the population structure and some reproductive traits of Urocaris longicaudata collected in Laguna de Términos, Campeche, Mexico in October and December 2009, and February and April 2010. A total of 2977 specimens were collected of which 1596 were females (including 276 ovigerous) and 1381 were males. Femal...
Parasitic isopods, particularly members of the Bopyridae that infest crustacean hosts, have received scant study in many geographic regions. As part of a project aimed at documenting parasites of fish and invertebrates from the coast of Yucatán, Mexico, 2,467 individuals of the fiddler crab Uca spinicarpa were collected from March 2002 to July 2007...
The presence of a male in a population of terrestrial isopods can accelerate the onset of female reproduction, a feature that has been suggested also to occur in bopyrid isopods. This paper aims to estimate the influence of the male presence on the ovarian maturation of Bopyrina abbreviata. Females of B. abbreviata of different sizes were collected...
Currently, 13 species of bopyrid isopods have been allocated to the genus Schizobopyrina Markham, 1985 (Williams & Boyko, 2004), most of them dis- tributed throughout the Pacific and Indian oceans (Markham, 1985). Three species have been recorded from American waters: Schizobopyrina bruscai Campos & Campos, 1990, Schizobopyrina striata (Nierstrasz...
Growth is an important ecological factor of species on which information is scant for host–parasite associations. A sample of 680 Hippolyte zostericola parasitized by the isopod Bopyrina abbreviata were collected at Términos Lagoon, Mexico, to evaluate the growth of both members of this association by the von Bertalan y method, as well as longevity...
Morphometric data are presented for developmental stages of Bopyrinella thorii (Richardson, 1904), obtained from 380 individuals of Thor floridanus Kingsley, 1878 infested by this parasite and collected by trawl net in Bahía de la Ascensión, Quintana Roo, Mexico. The close relationships between the sizes of host and parasite (r2 = 0.93) and between...
Bopyrina abbreviata Richardson, 1904 parasitizes caridean Hippolytidae, important consumers of submerged aquatic vegetation. This study evaluates the prevalence and reproductive aspects of the parasite at two-month intervals during an annual cycle in the Gulf of Mexico. The average prevalence of B. abbreviata was 0.37% (range 0.01-1.47%). Sex ratio...
The aim of this paper is to describe the population structure and some reproductive aspects of Hippolyte zostericola during an annual cycle. Samples were taken bimonthly, from June 2009 to April 2010, with a Colman–Seagrove sledge net on seagrass meadows located in the internal margin of Isla del Carmen, Campeche, Mexico. The population structure o...
This study describes changes in the secondary sexual characters of Thor floridanus Kingsley, 1878 males, caused by the isopod Bopyrinella thorii (Richardson, 1904). Of 380 specimens of T. floridanus examined, the females were more often infested (n = 313) than the males (n = 41), and had a wider size range (0.7-2.85 mm POCL) compared to the males (...
The association of Bopyrinella thorii (Richardson, 1904) with Thor floridanus Kingsley, 1878 in seagrass beds of the Mexican Caribbean has been previously reported upon, although without mention of other data relative to the parasitic species' biology. The purpose of this study was to provide information on reproductive aspects of B. thorii from Ba...
Beds of a Thalassia testudinum were sampled in the Laguna de Términos, Gulf of México to know the prevalence of infestation of the hippolytid shrimp Hippolyte zostericola (Smith, 1873). A total of 30, 351 specimens were collected with a Colman-Seagrove sledge net. The host species exhibited a mean of 8.90 specimens/m2 and a sexual ratio of 1.1 fema...
