“…Similar antero-posteriorly compressed processes on carapace have been described for Munidopsis sonne Baba, 1995, known from active thermal vent area in the North Fiji Basin, SW Pacific (Baba, 1995), M. proales Ahyong & Poore, 2004, and M. tasmaniae Ahyong & Poore, 2004, Komai, 2011, from off Japan (Komai, 2011), and M. naginata Cubelio et al, 2007, from hydrothermal vent off Okinawa, Japan. Munidopsis sonne was later reported from Brothers Seamount, Kermadec Volcanic Arc, by Cubelio et al (2007), but the illustrations are rather poor and do not show the typical antero-posteriorly compressed, truncate processes described by Baba (1995, fig.…”

A new species of Munidopsis Whiteaves, 1784 is described from the SW Gulf of California, western Mexico. The new species differs from all other known species of Munidopsis of the East Pacific by the presence of numerous antero-posteriorly compressed processes on the carapace, many of which are truncate and with crenulated anterior margin, by its oval-shaped carapace, wider in its posterior half, and by the short, subrectangular, narrow rostrum with an upturned distal portion. It also differs from the East Pacific species and other species of Munidopsis by the densely pitted carapace and appendages.Key words. -Gulf of California, western Mexico, Munidopsis new species RESUME Une nouvelle espèce de Munidopsis Whiteaves, 1784 est décrite du golfe de Californie SW, à l'ouest du Mexique. La nouvelle espèce diffère de toutes les autres espèces connues de Munidopsis du Pacifique Est par la présence sur la carapace de nombreux processus comprimés antéro-postérieurement, dont un grand nombre est tronqué et avec un bord antérieur crénelé, par la forme ovale de la carapace qui est plus large dans sa moitié postérieure, et par le rostre court, subrectangulaire, étroit et dont l'extrémité est tournée vers le haut. Elle se distingue aussi des espèces du Pacifique Est et des autres Munidopsis par la présence de nombreuses petites perforations sur la carapace et sur les appendices.Mots clés. -Golfe de la Californie, Mexique de l'ouest,

Evolutionary and biogeographical patterns of barnacles from deep‐sea hydrothermal vents

2015

The characterization of evolutionary and biogeographical patterns is of fundamental importance to identify factors driving biodiversity. Due to their widespread but discontinuous distribution, deep‐sea hydrothermal vent barnacles represent an excellent model for testing biogeographical hypotheses regarding the origin, dispersal and diversity of modern vent fauna. Here, we characterize the global genetic diversity of vent barnacles to infer their time of radiation, place of origin, mode of dispersal and diversification. Our approach was to target a suite of multiple loci in samples representing seven of the eight described genera. We also performed restriction‐site associated DNA sequencing on individuals from each species. Phylogenetic inferences and topology hypothesis tests indicate that vent barnacles have colonized deep‐sea hydrothermal vents at least twice in history. Consistent with preliminary estimates, we find a likely radiation of barnacles in vent ecosystems during the Cenozoic. Our analyses suggest that the western Pacific was the place of origin of the major vent barnacle lineage, followed by circumglobal colonization eastwards through the Southern Hemisphere during the Neogene. The inferred time of radiation rejects the classic hypotheses of antiquity of vent taxa. The timing and the mode of origin, radiation and dispersal are consistent with recent inferences made for other deep‐sea taxa, including nonvent species, and are correlated with the occurrence of major geological events and mass extinctions. Thus, we suggest that the geological processes and dispersal mechanisms discussed here can explain the current distribution patterns of many other marine taxa and have played an important role shaping deep‐sea faunal diversity. These results also constitute the critical baseline data with which to assess potential effects of anthropogenic disturbances on deep‐sea ecosystems.

“…2 has, to date, only been observed in Manus and North Fiji Basin (T. Komai, personal communication). Squat lobsters in the genus Munidopsis occupy numerous deep-sea habitats, including cold seeps [28] , seamounts [29] , and wood- and whale-falls [30] , and are also generally distributed along the continental slope and bathyal depths [31] , [32] . M. lauensis is frequently observed in large aggregations near active hydrothermal venting [26] , [33] , [34] , but also occurs in lesser numbers at inactive sulfide edifices on the vent periphery [35] and in still lower abundance as one moves away from the vent field (i.e., >500 m; Thaler, personal observation).…”

Comparative Population Structure of Two Deep-Sea Hydrothermal-Vent-Associated Decapods (Chorocaris sp. 2 and Munidopsis lauensis) from Southwestern Pacific Back-Arc Basins

et al. 2014

Studies of genetic connectivity and population structure in deep-sea chemosynthetic ecosystems often focus on endosymbiont-hosting species that are directly dependent on chemical energy extracted from vent effluent for survival. Relatively little attention has been paid to vent-associated species that are not exclusively dependent on chemosynthetic ecosystems. Here we assess connectivity and population structure of two vent-associated invertebrates—the shrimp Chorocaris sp. 2 and the squat lobster Munidopsis lauensis—that are common at deep-sea hydrothermal vents in the western Pacific. While Chorocaris sp. 2 has only been observed at hydrothermal vent sites, M. lauensis can be found throughout the deep sea but occurs in higher abundance around the periphery of active vents We sequenced mitochondrial COI genes and deployed nuclear microsatellite markers for both species at three sites in Manus Basin and either North Fiji Basin (Chorocaris sp. 2) or Lau Basin (Munidopsis lauensis). We assessed genetic differentiation across a range of spatial scales, from approximately 2.5 km to more than 3000 km. Population structure for Chorocaris sp. 2 was comparable to that of the vent-associated snail Ifremeria nautilei, with a single seemingly well-mixed population within Manus Basin that is genetically differentiated from conspecifics in North Fiji Basin. Population structure for Munidopsis lauensis was more complex, with two genetically differentiated populations in Manus Basin and a third well-differentiated population in Lau Basin. The unexpectedly high level of genetic differentiation between M. lauensis populations in Manus Basin deserves further study since it has implications for conservation and management of diversity in deep-sea hydrothermal vent ecosystems.
