Lepidophthalmus Louisianensis

A new species of Lepidophthalmus lacking a ventral median sclerite on the second abdominal somite is described from coastal waters of the southwestern Gulf of Mexico. Lepidophthalmus statoni sp. nov., originally recognized only as a unique population in allozyme studies, is sympatric with the ventrally plated species Lepidophthalmus manningi Felder & Staton, 2000, but more closely resembles Lepidophthalmus louisianensis (Schmitt, 1935) from the northern and northwestern Gulf of Mexico. Apparently restricted to intertidal and shallow subtidal tropical waters, the new species is known to range from western Campeche to middle-upper reaches of Veracruz, Mexico. As many members of the genus, it commonly inhabits euryhaline inlets, estuaries, and protected shorelines, including richly organic muddy to clayey sands and sandy muds adjacent to shoreline vegetation. Coloration is documented and discussed as a tool to facilitate field identifications, as are morphological characters.

Shallow Coastal Waters

A new species of diogenid hermit crab, Diogenes minimus, is described and illustrated on the basis of material from shallow subtidal waters (5–19 m) in central Japan. It appears close to D. holthuisi Asakura & Tachikawa, 2010, but easily distinguished from the latter by the shape of the antennal acicle, non-elongate male left cheliped and the armature of the right cheliped merus. Including the new species, 14 identified species of Diogenes are now known from Japanese waters. A brief overview on species of Diogenes recorded from Japanese waters is given.

A New Species

Astropecten cingulatus is a conspicuous species, which displays a large superomarginal plate series on the abactinal surface. Herein we describe a new species from off the Texas coast that shows the superficial appearance of A. cingulatus, including these large superomarginal plates, but with armature differing from that of typological A. cingulatus. This species shows the actinal surface of the inferomarginal plates without the squamules present on A. cingulatus. In addition, the adambulacral plates possessed but a single central large spine surrounded by a circle of spines rather than spine rows. The abactinal paxillar region was also very narrow. Statistical analysis of these and other morphological characters showed the specimens differed significantly from those of A. cingulatus. The regression of the slope of R:SM# vs. R was significant but the intercept was not. Therefore the two species are indistinguishable at small sizes based on R:SM. Compared to known Atlantic Astropecten spp. these observed characters warrant the description of a new species, Astropecten karankawai, for the specimens from off the coasts of Texas and Mexico.

A New Species

New collections made by the French research vessel Thalassa and the Brazilian Astro Garoupa on the Brazilian continental slope, between 11° and 23° S revealed a great diversity of deep-sea gadiforms obtained between 200 and 2270 m. Of the 34 species collected, 13 (38%) are being reported for the first time in the western South Atlantic and one may represent a new species. The most species-rich family in the area is Macrouridae (25 species), followed by Moridae (4), Phycidae (2), Merlucciidae (2), and Bregmacerotidae (1). Most of the species collected is also found in the Gulf of Mexico and Caribbean and have their known ranges of distribution extended into the tropical waters of central Brazil. Four species typically occur in temperate waters and were found only in the southernmost stations. A summary comparison of the bathymetric distributions of each species on the slope is provided.

A New Species

A new species of peppermint shrimp, Lysmata baueri n. sp., is described based on a single specimen from the eastern Gulf of Mexico. The new species can be distinguished from other morphologically similar species of Lysmata Risso, 1816 by the number of teeth, length and shape of the rostrum, the length of the antennular peduncle relative to the scaphocerite, the number of meral and ischial articles in the second pereiopods, and the number of spines on the flexor margin of the dactyli from the third to fifth pereiopods. Morphological characters demonstrate that L. baueri n. sp., is most closely related to the eastern Pacific L. californica (Stimpson, 1866), L. nayaritensis Wicksten, 2000 and L. porteri (Rathbun, 1907).

Lateral Plates

A new species of protosquillid mantis shrimp is described from the coastal waters of Korea and Japan. Chorisquilla orientalis n. sp. is distinguished from congeners by the combination of deep grooves and pits on the dorsal surface of abdominal somite 5, 8–14 spines on lateral margin of the telson, numerous minute dorsal spines on the telson and abdominal somite 6, and large, pyriform submedian bosses on the telson preceded by a small rounded boss. Chorisquilla orientalis is morphologically closest to C. mehtae Erdmann & Manning, 1998, from Indonesia, but differs chiefly in the dorsal ornamentation of abdominal somite 6 and the telson and reaches a considerably larger size. Chorisquilla orientalis n. sp. shows developmental changes from juvenile to adult in the shape of the ocular scales and anterior margin of lateral plates of carapace, and in the number of lateral spines on telson. Also, C. mehtae Erdmann & Manning, 1998, which, to date has not been adequately illustrated, is redescribed and figured. A key to the Korean gonodactyloids is presented.

A description of a new species ofMagelona,M. parochilissp. nov. is presented, based on material collected from the Yellow Sea, China. The new species belongs to the ‘Magelona mirabilisgroup’ of magelonids, possessing a rounded prostomium, lacking prostomial horns and specialized chaetae on chaetiger 9. Paired anteriorly open pouches are present between chaetigers 11–12 and 14–15 (occasionally between chaetigers 17–18).Magelona parochilissp. nov. inhabits intertidal zones and shallow subtidal waters characterized by sandy mud.

A New Species

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.

A New Species

Abstract A new species of micromorphic articulate brachiopod (Rhynchonellida) Lambdarina jugowiensis sp. nov., from the upper Visean (Sokolec Beds) of central Sudetes, SW Poland, is described. The studied specimens are calcified, what makes them unique in respect of their state of preservation. The material is represented by a full range of growth stages; from brephic to gerontic. Based on its morphological features and the palaeogeographical distribution of all its known species, two main evolutionary lines are proposed for the genus; the Australian and the European ones. Lambdarina was widely distributed in the equatorial-tropical waters of marginal seas of the Palaeotethys Ocean, mostly during Mississippian time.
