Reexamination of the type material of Squilla? kiowana Scott, 1970 and study of additional specimens of the same taxon indicates that it is a mecochirid decapod referable to a new genus, Huhatanka. This assignment brings to five the number of North American species referable to the Mecochiridae.

In this study, we constructed the first molecular phylogeny of the diverse crab superfamily Majoidea (Decapoda: Pleocyemata: Brachyura), using three loci (16S, COI, and 28S) from 37 majoid species. We used this molecular phylogeny to evaluate evidence for phylogenetic hypotheses based on larval and adult morphology. Our study supports several relationships predicted from larval morphology. Thes...

Recent phylogenetic work (Ashelby et al., 2012) has demonstrated the need for a fresh appraisal of the systematic status of some Palaemoninae genera. In the present contribution the accumulated morphological as well as molecular evidence is reviewed. The genera Palaemonetes, Exopalaemon and Coutierella are demonstrated to be junior synonyms of Palaemon, which now contains 83 species. As a resul...

A new crab Liomerinae, Neoliomera moana sp. nov., is described from the Marquesas Islands, based on three specimens collected by hand at the entrance of submarine caves at depths of 6-28 m. Within the genus the new species belongs to a group of six species that have the carapace cristate on the anterolateral margins. It can be recognized by the presence of a double crest on the upper margin of ...

The information about the family Munidopsidae in Chile is scarce and sparse, making identification of new material. difficult. Due to this we lack precise information about the number and accurate distribution of Chilean species. Recent expeditions to Chile have collected specimens of this group, allowing an exhaustive review of the registers and collections in four museums in the country. A to...

A new species of Espeleonaushonia is described from a single specimen collected in an underwater cave in Babeldaob Island, Republic of Palau. The new species is placed in Espeleonaushonia based on the following characters: exopod of third maxilliped well developed, propodus of first pereopod with spines on dorsal surface and along mesial and lateral margins; second pereopod not chelate with dac...

Galathea ternatensis De Man, 1902 and Raymunida iranica n. sp., are reported from the Iranian coast as the first records of squat lobster species from the Persian Gulf. The new species morphologically resembles R. cagnetei Macpherson & Machordom, 2000, but is unique in the genus in having a small spine near the base of each supraocular spine and a spine ventral to the second branchial marginal ...

Cancer urania Herbst, 1801, is the type species of the leucosiid genus Coleusia Galil, 2006. Its identity has been a subject of confusion due to various taxonomical and nomenclatural issues. We redescribe the species, discuss its complex history and taxonomy, and a female syntype is designated as the lectotype of the species to clarify any lingering ambiguities concerning the type material of C...

The inachid spider crab genus, Parapleisticantha Yokoya, 1933 [type species: Parapleisticantha japonica Yokoya, 1933] is removed from the synonymy of Pleistacantha Miers, 1879 [type species: Pleistacantha sanctijohannis Miers, 1879], and recognised as a valid genus. Parapleisticantha differs from Pleistacantha sensu stricto primarily by having a less spiny carapace, stouter and more inflated ma...

A new species of leucosiid crab of the genus Coleusia Galil, 2006, is described from South and Southeast Asia. Coleusia huilianae n. sp. is distinguished from the superficially similar C. urania (Herbst, 1801) in the shape of the apical process of the first male gonopod which is digitate and curved laterally in the former (beak-like and curved interiorly in the latter); possessing smaller and s...
