“…Unfortunately, the developmental pattern in the two marine fossil aeglids Haumuriaegla Feldmann 1984 andProtaegla Feldmann et al 1998 is not known. In recent works on phylogenetic relationships amongst anomuran superfamilies, Aegloidea has been determined either as sister group to the clade Lithodoidea-Hippoidea (McLaughlin et al 2007) or as sister taxon to Lomisoidea, with the clade Aegloidea/Lomisoidea allocated as sister group to Chirostyloidea (Schnabel et al 2011).…”

The present paper contains the complete description of the external morphology of the first juvenile stage of Aegla perobae analysed through light microscopy (LM) and scanning electron microscopy (SEM). Newly-hatched juveniles were obtained from ovigerous females kept under laboratory conditions. Hatching is asynchronous, taking 2-4 days for all juveniles of a single brood to hatch. Average carapace dimensions are 1.54 mm wide and 1.69 mm long (rostrum excluded). Morphology of the carapace, of the cephalothoracic appendages (antennule, antenna, mandible, maxillule, maxilla, maxillipeds, and pereopods), of the pleon, and of the tail fan (telson plus uropods) are described in detail. Aegla perobae juveniles can be readily differentiate from the first juveniles of other aeglids species described so far by the upwardly curved condition of the distal region of the rostrum and the distinct groove along the orbital sinus produced the elevated free in this area. Pleopods 2-5 are present as rudimentary digitiform buds. Rudimentary pleopods are still present in adult males of the species, a trait not yet described in freshwater aeglids. This curious condition is compared and discussed in the light of the current knowledge of early postembryonic developmental patterns found in other anomurans.

“…Mitochondrial DNA sequences of remaining Munidopsis and Galacantha terminals were derived from ethanol preserved specimens in the collections of Museum Victoria, Melbourne (NMV), the National Institute of Water and Atmospheric Research, Wellington (NIWA), the University of Louisiana at Lafayette, Louisiana (ULL), and the Universidad Católica del Norte, Coquimbo (UCN). The Munidopsidae is sister to the remaining galatheoids (Ahyong et al, 2009;Schnabel et al, 2011), so analyses were rooted to selected Galatheidae and Munididae.…”

The Munidopsidae, one of three squat lobster families in the Galatheoidea, contains the deepest dwelling squat lobsters, with some occurring at abyssal depths. Munidopsids were formerly divided into two subfamilies: Shinkaiinae, for the unusual hydrothermal vent genus Shinkaia; and Munidopsinae for remaining taxa. Four munidopsid genera are currently recognised (Shinkaia, Leiogalathea, Galacantha and Munidopsis) but the largest genus, Munidopsis, is highly diverse morphologically, with multiple genera or subgenera currently in its synonymy. Phylogenetic studies of galatheoids focussed on high level relationships indicate that Leiogalathea is sister to other munidopsids, but the position of Shinkaia with respect to Munidopsis and Galacantha is unclear, as is the reciprocal monophyly of the latter two genera. Phylogenetic analyses of the Munidopsidae based on mitochondrial 16S and COI sequences, sampling all current genera (including the majority of the formerly recognised subgenera), indicate that the generic and former subfamily classifications do not reflect the phylogeny. Shinkaia and Galacantha clades are nested within Munidopsis rendering the genus paraphyletic and the bi-subfamily classification phylogenetically invalid. Many of the Munidopsis clades recovered, however, correspond well to formerly recognised genera or subgenera, indicating good prospects for a natural subdivision of Munidopsis. Crown

“…Munida gregaria (Fabricius 1793) is a benthic squat lobster species of the continental shelf and upper slope off southern South America, New Zealand, and southern Australia (Baba et al 2008;Schnabel et al 2011). Of 274 species in the genus Munida, this cold temperate species is suggested to be the only transpacific species in its family on both sides of the East Pacific Barrier, whose dispersal might have occurred by rafting on buoyant macroalgae via the Antarctic Circumpolar Current (Nikula et al 2010;Perez-Barros et al 2014;Macpherson 2015).…”
