A new species of chirostylid squat lobster,Uroptychus tuerkayisp. nov., is described based upon material collected by the French “Seamount 2” project (1993) from the Atlantis-Great Meteor Seamount Chain south of the Azores Islands, at a depth of 340-730 m.Uroptychus tuerkayiresemblesU. maroccanusTürkay, 1976 from the Moroccan coast, but it can be readily distinguished by the eyes being distinctly longer instead of as long as broad (globular inU. maroccanus), the antennal article 5 with a small instead of prominent distomesial spine, the anterolateral spine of the carapace slightly smaller than or subequal to, instead of much smaller than the lateral orbital spine, the pterygostomian flap anteriorly acuminate and not strongly produced to a spine as inU. maroccanus, and in having pereopod 1 with obsolescent instead of distinct spines on the merus and carpus. This is the sixth species ofUroptychusfrom the eastern Atlantic. A key to the eastern Atlantic species ofUroptychusis provided.

A new species of the chirostylid squat lobster genus Uroptychodes Baba, 2004, U. fuscilineatus, is described and illustrated on the basis of a single ovigerous female from the Uraga Channel, central Japan, at depth of 250 m. The new species appears most similar to U. spinimarginatus (Henderson, 1885) and U. yapensis Dong, Gan & Li, 2021 among the 13 known congeners, but is notable in the pereopod 2 not being definitely more slender than the pereopods 3 and 4 and the remarkably spinose pereopods 1–4. A possible association of the new species with crinoid is suggested. An updated identification key to species of Uroptychodes is presented.

A new bopyrid, Pseudione chiesai n. sp., is herein described based on an ovigerous female and an adult male found in the right branchial chamber on a specimen of Munida spinosa Henderson, 1885. This parasite was collected in the Mar del Plata submarine canyon at 819 m depth during the expedition “Talud Continental I” carried out by the Argentine RV Puerto Deseado in 2012. P. chiesai n. sp. belongs to the Pseudione “crénelés” group sensu Bourdon (1972, 1976), which currently contains seven species, all of which have galatheoid crabs as hosts. P. chiesai n. sp. can be separated from the other species in the Pseudione “crénelés” group by the following combination of characters: (1) both sides of the body convex, (2) frontal lamina with a few, shallow indentations, (3) coxal plates 1–4 and tergal projections 1–4 with distinct irregular margins, mainly on the right side, (4) pereomeres 5–7 with single/branched lateral digitations, (5) maxilliped palp well-developed and setose, and (6) pleon with lateral plates 1–5 distally rounded and directed laterally. The taxonomic position of this new species is briefly discussed.

Leiopathes montana, a new species previously reported as L. glaberrima (Esper), is described from the plateau of the Great Meteor seamount (North Atlantic) at depth 300–335 m. The new species can be easily distinguished from all other species of the genus by very thin at tips, slightly bended terminal branchlets 0.15–0.2 mm in diameter above the base, rather long in comparison to the size of the colony, small compressed triangular spines 0.02–0.03 mm long and 0.22–0.5 mm apart, and small densely-set polyps (6–9 per centimeter). Eight species assigned to the genus Leiopathes represent two distinct groups: (1) sparsely branched forms with longer terminal branchlets (L. glaberrima, L. valdiviae, L. acanthophora, L. bullosa, L. montana), and (2) forms with sinusoidal stem and branches, and very short branchlets forming flabellate fronds (L. expansa, L. grimaldii, L. secunda). The largest in size syntype of L. grimaldii Roule, 1902 collected off the Azores is proposed here as the lectotype, since it is the only full grown and complete specimen and also the only specimen illustrated and described in detail by Roule.

A new species of the genus Munida Leach, 1820, is described and illustrated based on a single specimen from the deep-sea hydrothermal vent on the Eastern Pacific Rise. Munida alba sp. nov. closely resembles M. ampliantennulata Komai, 2011, M. watatsumin Komai, 2014. and M. magniantennulata, but differences in the morphologies of the third maxilliped, pollex of the cheliped and the third segment of the antennal peduncle readily distinguish the new species from the three relatives. The new species is the fourth of the genus occurring at the hydrothermal vent areas.

Hendersonida parvirostrissp. nov. is described from Papua New Guinea. The new species can be distinguished from the only other species of the genus, H. granulata (Henderson, 1885), by the fewer spines on the dorsal carapace surface, the shape of the rostrum and supraocular spines, the antennal peduncles, and the length of the walking legs. Pairwise genetic distances estimated using the 16S rRNA and COI DNA gene fragments indicated high levels of sequence divergence between the new species and H. granulata. Phylogenetic analyses, however, recovered both species as sister species, supporting monophyly of the genus.

Squat lobster specimens belonging to the family Munididae were recently collected along the southwestern coast of the mainland of India and in the Andaman Islands. The specimens belong to two known species, Agononida prolixa (Alcock, 1894) and Munida compacta Macpherson, 1997, and a new species, Paramunida bineeshisp. nov. We here redescribe A. prolixa and describe and figure the new species. Munida compacta is newly recorded from India, and we figure the live coloration. In addition, molecular and phylogenetic analyses of two mitochondrial markers (16S rRNA and COI) revealed the phylogenetic relationships of M. compacta and P. bineeshisp. nov. with their most closely related congeners. The genetic similarity among the individuals of M. compacta from different locations is also addressed.

Uroptychus cartesi, a new species of squat lobster belonging to the family Chirostylidae, is described based upon materialrecently collected from the Bank of Galicia, a deep seamount located off north-west Spain. This is now the fifth speciesof the genus known from the eastern Atlantic. The four species previously recorded in the region (U. bouvieri, U. concolor,U. maroccanus and U. rubrovittatus) are morphologically rather remote from the new species. The spinose carapace lat-eral margin links U. cartesi to U. bouvieri but the other characters displayed by the new species are largely different fromthose of that species. Uroptychus cartesi is distinguished from U. bouvieri by the epigastric region having denticles ar-ranged in small arcs transversely rather than a pair of spines behind the eyes; the anterolateral spine of the carapace ismuch larger than, instead of subequal to, the lateral orbital spine; the P2–4 propodi are slightly more than half, instead oftwice, the length of dactyli; and the penultimate flexor marginal spine of P2–4 dactyli are twice as broad as, rather than as broad as the antepenultimate spine. A key to the species of Uroptychus from the eastern Atlantic is provided.
