We describe a new species of stygobiont atyid shrimp of the genus Halocaridinides Fujino Shokita, 1975 from subterranean brackish and freshwater environments on Socotra Island (Yemen). This is the first atyid shrimp discovered in the Socotra Archipelago. This Socotran endemic is the second species of Halocaridinides recorded from an Indian Ocean island and the first to occur in non-anchialine environments. The new species is characterized by the absence of eye pigmentation, a reduced rostrum and the presence of a single spine in the uropodal exopod diaeresis...

This study is part of a series of checklists resulting from a long-term multidisciplinary project on the biodiversity of decapod crustaceans from the marine and coastal environments (including estuaries) of São Paulo State (Brazil). For that, we integrated molecular techniques (mitochondrial DNA markers) and morphological analyses of adult specimens for an accurate and detailed identification. The DNA markers were used when the morphological identification was doubtful, particularly in the recognition of cryptic species...

The genus Pasiphaea Savigny, 1816 (Caridea: Pasiphaeidae) includes 71 species, of which vast majority inhabit in the meso or bathypelagic zones in the world oceans. A new species is described herein, sampled during the project "ABRACOS 2" (Acoustic along the BRazilian COast) nearby the Rocas Atoll and Fernando de Noronha Archipelago, in Brazilian waters. Pasiphaea antea n. sp. appears close to Pasiphaea dorsolineatus Komai Chan, 2012 described from off Hawaii, but is distinguished from the latter by the different shape of the rostrum, the mid-dorsal line of the carapace sharply carinate in the anterior half, and the possession of more numerous spiniform setae on the meri of the pereopods 1 and 2...

Tomoyuki Komai, Jun Ohtomi
A new species of the snapping shrimp genus Alpheus Fabricius, 1798, A. longipalma, is described and illustrated on the basis of material from Kagoshima Bay, Kyushu, Japan. It is referred to the A. brevirostris (Olivier, 1811) species group, and appears closest to A. macroskeles Alcock Anderson, 1894, known with certainty from the Bay of Bengal and Andaman Sea, and A. talismani Coutière, 1898 from the eastern Atlantic. The greatly elongate minor cheliped in males, being subequal to or longer than the major cheliped with proportionally shorter dactylus distinguish the new species from A...

Stenopodidea Claus, 1872 (Crustacea: Decapoda) is one of the major groups of decapods crustaceans. Hitherto, only one complete mitochondrial genome (mitogenome) from the family Stenopodidae is available for the infraorder Stenopodidea. Here, we determined the complete mitogenome of Spongiocaris panglao de Grave and Saito, 2016 using Illumina sequencing, representing the first species from the family Spongicolidae. The 15,909 bp genome is a circular molecule and consists of 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and one control region...

There are a limited number of model species for decapod experimental embryology. To improve our understanding of developmental pattern evolution in the Decapoda, here we describe the early embryonic development of the caridean shrimp Lysmata boggessi, from immediately after fertilization to the hatching of the zoea larva, using fluorescence microscopy and whole-mount nuclear staining with 4',6-diamidino-2-phenylindole. Lysmata boggessi follows the standard caridean pattern of early development, with early holoblastic cleavage that will later become superficial, to form a blastoderm...

Macrobrachium amazonicum is a commercially important freshwater prawn with a high degree of reproductive plasticity. The species is classified into two groups: coastal populations, with larger individuals exhibiting high fecundity and needing brackish water for larval development; and continental populations, with smaller specimens exhibiting low fecundities and completing metamorphosis in freshwater. The objective of this study was to investigate the influence of environmental factors in the fecundity, egg size and volume, and reproductive output in females of M...

We report a new microsporidium from a key species of the estuarine communities of the Gulf States, the Riverine grass shrimp, Palaemonetes paludosus. A milky-white shrimp was found in the Mobile Bay Delta, a large, oligohaline-freshwater wetland in Alabama, USA. Light microscopy of smears and thick sections of the abdominal tissues demonstrated infection with microsporidian spores enclosed in sporophorous vesicles (SVs) in sets of eight. Broadly oval spores measured 2.9 ± 0.06 × 1.7 ± 0.03 µm (2...

A new species of alpheid shrimp, Thuylamea shiranui, is described and illustrated on the basis of five specimens from Yatsushiro Sea, western Kyushu, Japan. It is closely related to T. camelus Nguyên, 2001, the type species of the heretofore monotypic genus Thuylamea Nguyên, 2001, known from South China, Vietnam and Singapore. The complete lack of submedian posterodorsal crests on the carapace and the relatively long antennular peduncle distinguish the new species from T. camelus. The generic diagnosis of Thuylamea is emended to accommodate the new species...

One new species and three new distribution records for the family Crangonidae (Crustacea: Decapoda) are reported from Western Australia. A new species, Philocheras gardenensis sp. nov. is described and illustrated based on specimens collected from the Western Australia. The new species closely resembles Philocheras fasciatus (Risso, 1816), but can be distinguished easily by the absence of lobe-like folds on either side of the middle line of the carapace, the presence of a lateral carina extending from the branchiostegal spine, the longer middorsal carina and distolateral tooth of the antennal scale...

The family Crangonidae comprises 22 genera and 219 species. Six species are recorded in the Southwestern Atlantic. In this paper, two species of this family, Pontophilus brevirostris Smith, 1881 and Sabinea hystrix (A. Milne-Edwards, 1881) are recorded for the first time to southwestern Atlantic Ocean. Additionally, we record the occurrence of Parapontocaris caribbaea (Boone, 1927), Parapontophilus gracilis (Smith, 1882) and Philocheras gorei (Dardeau, 1980) to the Northeast of Brazil. Through this paper, we raised the number of Cragonidae species to eight from recorded from southwestern Atlantic (Brazilian deep waters)...

Two species of alpheid shrimp collected from a marine cave off Ie Island, Okinawa Islands, Ryukyu Islands, Japan, are reported. Caligoneus cavernicola n. gen., n. sp., is described on the basis of six specimens, including two ovigerous individuals. The new monotypic genus shares a number of features with Salmoneus Holthuis, 1955 and Triacanthoneus Anker, 2010; however, the dorsally elevated rostrum and the symmetrical pereopods 1 (= chelipeds) of "minor form" distinguish Caligoneus n. gen. from the latter two genera...

Caridea, an infraorder of shrimps coming under Pleocyemata was first reported from the oceans before 417 million years followed by their radiation recorded during the Permian period. Hitherto, about 3877 extant caridean species were accounted within which one quarter constitute freshwater species. Freshwater prawns of genus Macrobrachium (Infraorder Caridea; Family Palaemonidae), with more than 240 species are inhabitants of diverse aquatic habitats like coastal lagoons, lakes, tropical streams, ponds and rivers...

Fresh caught Clibanarius vittatus [SW, 31‰ salinity (S)] were acclimated to a dilute medium (15‰ S) for 10 days, employing silver staining to locate gill ion transporting tissue, immunofluorescence to localize the Na+ /K+ -ATPase α-subunit in the lamellae, and electron microscopy to portray ultrastructural changes in the gill epithelia. Na+ /K+ -ATPase activity was characterized kinetically in a gill microsomal fraction, including synergistic stimulation by NH4 + plus K+ . Silver staining revealed that all 26 phyllobranchiate arthro- and pleurobranchiae participate in ion transport...
