Six decapod crustacean species, including one gebiidean and five anomurans, are reported as new to the marine fauna in the Sea of Japan based on material collected from the coast of Tottori Prefecture, western Japan. Among them, the munidid squat lobster Paramunida tricarinata (Alcock, 1894) is new to the Japanese fauna. In addition to the six species, the occurrence of the diogenid hermit crab Paguristes versus Komai, 2001 in the Sea of Japan is confirmed on the basis of specimens newly obtained from Tottori Prefecture. The current knowledge on the fauna of Gebiidea and Anomura in the western Japanese coast of the Sea of Japan is also briefly summarized.
... This new genus accommodated the species belonging to the scabra group plus two new described species P. longior and P. setigera. Paramunida was substantially enlarged through the MUSORSTOM-TDSB expeditions in waters around the Philippines, Indonesia and New Caledonia (Macpherson 1993;Baba 2005), Wallis and Futuna (Macpherson 1996), eastern Australia (Ahyong and Poore 2004), Fiji and Tonga (Macpherson 2004), French Polynesia (Macpherson 2006), New Zealand (Ahyong 2007), Taiwan and Japan Macpherson and Baba 2009), and the Solomon Islands (Cabezas et al. 2009). Most recently, the taxonomic revision of the genus resulted in the description of 11 new species (Cabezas et al. 2010), and examination of material collected during the PANGLAO expeditions added three new ones namely P. akaina, P. aspera and P. aurora (Cabezas & Chan, 2014). ...
The genus Paramunida belongs to the most diverse family of galatheoids and it is commonly reported from the continental slope across the Indian and Pacific Oceans. Examination of material collected by the NOAA RV Townsend Cromwell Cruise near Christmas (Kiritimati) Island, Kiribati, revealed the existence of a new species of Paramunida (P. haigae), which represents the fourth record of the genus for the Central Pacific. Furthermore, recent efforts to unravel phylogenetic relationships and diversification patterns in Paramunida revealed P. granulata (Henderson, 1885) to be the most basally diverging taxon within the genus. This species is clearly distinguished from other species of Paramunida by the spinulation of the carapace and the length of the distomesial spine of the second antennal peduncle article, which in combination with a high level of genetic divergence suggest that this species represents a separate monotypic lineage. A new genus, Hendersonida
gen. n., is proposed to accommodate this species based on morphological and molecular evidence. An updated dichotomous identification key for all species of Paramunida is presented.
... The group has been the focus of increasing taxonomic attention in recent years, but little is still known about its origin and diversification. Here, we focus on the genus Paramunida, comprised of 37 species distributed across the Indo-West Pacific (Baba et al. 2008;Cabezas et al. 2009;Macpherson and Baba 2009;Cabezas et al. 2010), typically recorded at continental slope depths (200-700 m). Most species are restricted to single islands or archipelagos, with the greatest diversity (more than 80% of species) found around the southwestern Pacific region. ...
The diversification of Indo-Pacific marine fauna has long captivated the attention of evolutionary biologists. Previous studies have mainly focused on coral reef or shallow water-associated taxa. Here, we present the first attempt to reconstruct the evolutionary history--phylogeny, diversification, and biogeography--of a deep-water lineage. We sequenced the molecular markers 16S, COI, ND1, 18S, and 28S for nearly 80% of the nominal species of the squat lobster genus Paramunida. Analyses of the molecular phylogeny revealed an accelerated diversification in the late Oligocene-Miocene followed by a slowdown in the rate of lineage accumulation over time. A parametric biogeographical reconstruction showed the importance of the southwest Pacific area, specifically the island arc of Fiji, Tonga, Vanuatu, Wallis, and Futuna, for diversification of squat lobsters, probably associated with the global warming, high tectonic activity, and changes in oceanic currents that took place in this region during the Oligocene-Miocene period. These results add strong evidence to the hypothesis that the Neogene was a period of major diversification for marine organisms in both shallow and deep waters.
... Agononida incerta is represented by two or three unresolved species that co-occur along the Australian margin and elsewhere. Not all, particularly historical, records can be referred to one or other of these types and all records were combined and some may refer to A. rubrizonata (Macpherson and Baba 2009). The cell covering the western Gulf of Mexico and the Yucatan Basin (cell 122) reached into the eastern Pacific across the Central American land bridge. ...
Knowledge of squat lobster diversity has grown rapidly during the past two decades and has now reached a level where it is possible to attempt a biogeographic synthesis. Squat lobsters of the superfamilies Galatheoidea and Chirostyloidea are now represented by more than 1000 species world-wide (10% undescribed) across nearly all latitudes and depths; the potential for new species discoveries remains high. Patterns of global species richness indicate a distinct global centre of diversity in the tropical western Pacific from between New Caledonia, Indonesia and the Philippines, with progressively fewer species recorded with increasing distance from this centre. This pattern holds for taxa in both superfamilies and across all depths, although a single unified centre of diversity is less obvious for lower slope and abyssal species (>2000 m) compared with their shallow-water relatives.

The genus Paramunida belongs to the family Galatheidae, one of the most species rich families among anomuran decapod crustaceans. In spite of the genus has received substantial taxonomic attention, subtle morphological variations observed in numerous samples suggest the existence of undescribed species. The examination of many specimens collected during recent expeditions and morphological and molecular comparisons with previously described species have revelaled the existence of eleven new lineages. All of them are distinguished by subtle and constant morphological differences, which are in agreement with molecular divergences reported for the mitochondrial markers ND1 and 16S rRNA. Here, we describe and illustrate the new species, providing brief redescriptions for the previously known species, and a dichotomous identification key for all species in the genus.
... These crabs comprise one of the most species-rich families of the anomuran decapods. Currently, the family is known to accommodate 34 genera and 680 species (Baba and Fujita, 2008; Macpherson and Baba, 2009). According to Macpherson et al. (2010), galatheids are most diverse in the Pacific Ocean, including 476 species in 32 genera. ...
Galatheids are abundant, speciose and often commercially exploited decapods, which are distributed worldwide in marine habitats. In Central America, our knowledge concerning these squat lobsters is rather limited. Here we examined a large collection of galatheids to provide information about species diversity and distribution of these decapods in deep waters along the Pacific coast of Costa Rica. The material analyzed herein was retrieved from (a) commercial deepwater shrimp trawls (2004‑2009) and (b) specimens deposited in the collection of the Museo de Zoología, Universidad de Costa Rica. The material contained six species of squat lobster (Munida gracilipes, M. mexicana, M. obesa, M. refulgens, Munidopsis hamata, and Pleuroncodes monodon), with P. monodon (1600 ind.) and M. gracilipes (651 ind.) being the most abundant. This is the first record of M. mexicana for Costa Rica, confirming its geographic distribution from Mexico to Panama and Galapagos. All four Munida species were encountered in depths between 30‑384 m; P. monodon occurred between 150 and 350 m, while M. hamata was
collected substantially deeper (1190‑1281 m). Three species (M. gracilipes, M. obesa and P. monodon) showed a spatial distribution covering practically the entire Pacific coast of Costa Rica, while M. refulgens was absent along the central-southern and southern parts of this coast. Body size varied significantly among the four most common species. The material examined contained ovigerous females from all four Munida species, but in contrast, we did not retrieve any egg-bearing females of P. monodon nor of M. hamata. We provide a list of all galatheid deepwater species so far reported from Costa Rica and
conclude that the species diversity of these squat lobsters in Costa Rican deepwater zones is surprisingly high.
The genus Paramunida belongs to the family Munididae, one of the most speciose families among anomuran decapod crustaceans. During the PANGLAO 2004, PANGLAO 2005, and AURORA 2007 expeditions in the Philippines, eight species of the genus were collected, including a new record and three new species, namely Paramunida akaina, P. aspera, and P. aurora. These new lineages are distinguished by subtle and constant morphological differences, which are in agreement with molecular evidence from the mitochondrial markers ND1 and 16S. Here, we describe these new species, provide new distribution records, and present phylogenetic relationships within the genus.
Seven species of squat lobsters were collected during the TALUD XIV cruise in the Gulf of California, Mexico. Gastroptychus perarmatus (Haig, 1968) was collected for the second time since it was described and represents a first record of the genus in the tropical eastern Pacific. Its association with gorgonians is also noted from color pictures taken during a deep-water dive in another cruise in the area. Janetogalathea californiensis (Benedict, 1902) was captured in four sampling stations, in the same area where it has been previously reported. Three species of Munida Leach, 1820 were collected (M. bapensis Hendrickx, 2000, M. mexicana Benedict, 1902, and M. tenella Benedict, 1902). Records of M. bapensis of this cruise combined with additional captures of this species in 2007 in the same area indicate that it is the most abundant deep-water species of squat lobster in the northern part of the central Gulf of California. Among the species of Munida, M. tenella was second in abundance and included specimens much larger than previously known. The single record for M. mexicana fits within the currently known depth and geographical ranges. Only one species of Munidopsis Whiteaves, 1874 (M. depressa Faxon, 1892) was collected, in one of the deeper sampling stations visited during the cruise and its northernmost distribution limit within the Gulf of California is increased by ca two degrees of latitude. The seventh species collected during this survey, Pleuroncodes planipes Stimpson, 1860, is a common inhabitant of the California Current and the Gulf of California.
Six galatheid species are reported for the first time from Chinese waters: Bathymunida brevirostris (Yokoya, 1933), Coralliogalathea humilis (Nobili, 1905), Crosnierita dicata Macpherson, 1998, Enriquea leviantennata (Baba, 1988), Sadayoshia acroporae Baba, 1972 and Sadayoshia edwardsii (Miers, 1884). The four genera, Bathymunida Balss, 1914, Coralliogalathea Baba & Javed, 1974, Enriquea Baba, 2005 and Sadayoshia Baba, 1969, also represent first records for Chinese waters.
