One New Species

With the complexity of the family Phyllidiidae and the problems of identification in the Indo-West Pacific, the story of the Red Sea species continues to unfold. One new species and one new record are added to the Red Sea fauna, both belonging to the genus Phyllidiella. Phyllidiella amphitritesp. nov. is described from a single specimen from the northern Red Sea and clearly differs from all species of Phyllidiella in having pale yellow pigment on the tubercles. Phyllidiella zeylanica is newly recorded from the Red Sea with five specimen records and several photographed individuals; other than this, it has a western Indian Ocean distribution. Phyllidia schupporum was collected for the first time since its original description; because its distribution is now extended to the Persian Gulf, it is no longer considered endemic to the Red Sea. The distribution of the Red Sea endemic Phyllidia dautzenbergi is extended northwards to Hurghada, Egypt. A small specimen of the endemic Phyllidiopsis sinaiensis was found at 214–237 m depth just at the mouth of the Red Sea, which is a bathymetrical range extension from its previous shallow coral reef records. The identifications of other species are revisited. A new species of Paradoris is described as Paradoris hypocritasp. nov., differing from the well-known but localised West Pacific P. liturata which also resembles a phyllidiid. This new species was recorded many years ago by published photographs, and it is relatively common in the Red Sea, evidenced by several specimens and additional photographs. It is described herein, and is considered a Red Sea endemic, differing from both the unnamed Indian Ocean species and the named Pacific species.

The present study reports one new species of the Family Leptocheliidae Lang, 1973 and one new species of Pseudotanaidae Sieg, 1976 from Taiwan. The leptocheliid Paraleptochelia setosa sp. nov. can be differentiated from its congeners by both sexes having a two-articled exopod and five-articled endopod on the uropod, the female having coupling hooks on the inner margin of the maxilliped endite, the male having a five-articled antennule flagellum, and cheliped fixed finger with one large subtriangular denticle on the incisive margin in some individuals. The pseudotanaid Akanthinotanais pedecerritulus sp. nov. can be distinguished from its congeners by pereopods 2 and 3 having a sigmoid (S-shaped) dactylus, a unique feature in Akanthinotanais. The family Pseudotanaidae and the two genera are reported from Taiwan for the first time, as are the two genera for the West Pacific. Key morphological characters of all known Paraleptochelia and Akanthinotanais species are tabulated.

A New Species

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

Echinoderms of the Middle Ordovician Platteville and lower Galena Groups of north-central Illinois and south-central Wisconsin are represented by at least seven classes including the Homoiostelea, Cystoidea, Crinoidea, Stelleroidea, Edrioasteroidea, Cyclocystoidea, Echinoidea, and possibly Holothuroidea. The most abundant and diverse echinoderms are monocyclic and dicyclic inadunate and camerate crinoids, of which the cupulocrinids and glyptocrinids are best represented. Thirteen new species and one new genus of crinoids are described:Cremacrinus guttenbergensis, Anulocrinus forrestonensis, Isotomocrinus minutus, Carabocrinus oogyi, Dendrocrinus? springeri, Merocrinus britonensis, Cupulocrinus plattevillensis, C. molanderi, Reteocrinus rocktonensis, R. spinosus, Traskocrinus mahlburgi(n. gen. et sp.),Rhaphanocrinus buckleyi, Glyptocrinus charltoni, andG. pustulosis.One new species of rhombiferan cystoid,Coronocystis durandensis, is also described. Echinoids of the family Bothriocidaridae (Bothriocidaris solemin. sp. andNeobothriocidaris templetonin. sp.) are reported for the first time from North America and appear to be the earliest recorded occurrence. Remains of a third bothriocidarid characterized by coalesced podial pores have also been discovered. Light and scanning electron microscopy of well preserved cyclocystoid specimens reveal a number of previously undescribed morphologic features of the central disc and submarginal ring that may shed some light on their functional morphology.Cupulocrinus gracilisRamsbottom from the Upper Drummuck Group Starfish Bed at Thraive Glen near Girvan, Scotland, is here reassigned toC. drummuckensisn. sp.Echinoderms are associated with an abundant and diverse fauna consisting largely of suspension feeders, primarily strophomenid and orthid brachiopods and trepostome and cryptostome bryozoans. Other common groups include corals, trilobites, sponges, and mollusks. Filamentous brown, foliose red and siphonaceous green algae are associated with the fauna at some localities.Carbonate rocks of both the limestone and dolostone facies of the Platteville (Briton, Walgreen and Forreston Members) and lower Galene Groups in the study area consist primarily of abundant shelly invertebrates occurring as whole and broken, unabraded, commonly articulated remains “floating” in a calcisiltite matrix that is highly bioturbated. Carbonate sediments appear to have been deposited in a near-to below wave base, highly stable, open marine environment characterized by low depositional slopes, good circulation and low terrigenous influx.

Amphimedon (Porifera, Demospongiae, Haplosclerida, Niphatidae), a pantropical genus of reef and mangrove sponges, was recently recorded for the first time from the Red Sea suggesting a rarity which is not sustained by new reef surveys in the Gulf of Aqaba. Here we describe four species of Amphimedon occurring commonly in the Gulf of Aqaba. Among these, three are new to science, A. dinae sp.nov., A. jalae sp.nov. and A. hamadai sp.nov., the fourth one has been recently described as A. chloros Ilan et al., 2004. Although the latter species and our three new species are the first definite Ampimedon species recorded from the Red Sea, at least one previously described sponge from the region, Ceraochalina ochracea Keller, 1889 is suspected to belong to this genus as well. The status of the described and suspected Red Sea Amphimedon is discussed and compared to species recorded from neighbouring Indian Ocean waters.

Mascarene Archipelago

Many regions of the world remain unexplored in terms of the tardigrade diversity, and the islands of the Indian Ocean are no exception. In this work, we report four species of the family Echiniscidae representing three genera from Mauritius, the second largest island in the Mascarene Archipelago. Two species belong in the genus Echiniscus: Echiniscus perarmatus Murray, 1907, a pantropical species, and one new species: Echiniscus insularissp. nov., one of the smallest members of the spinulosus group and the entire genus, being particularly interesting due to the presence of males and supernumerary teeth-like spicules along the margins of the dorsal plates. The new species most closely resembles Echiniscus tropicalis Binda & Pilato, 1995, for which we present extensive multipopulation data and greatly extend its distribution eastwards towards islands of Southeast Asia. Pseudechiniscus (Meridioniscus) mascarenensissp. nov. is a typical member of the subgenus with elongated (dactyloid) cephalic papillae and the pseudosegmental plate IV’ with reduced posterior projections in males. Finally, a Bryodelphax specimen is also recorded. The assemblage of both presumably endemic and widely distributed tardigrade species in Mauritius fits the recent emerging biogeographic patterns for this group of micrometazoans.

A systematic account is given of 17 families, 25 genera, and 32 species of anthoathecate hydroids and limnopolyps reported from Hawaii. Applying Reversal of Precedence provisions in zoological nomenclature, the familiar hydrozoan genus names Hydractinia Van Beneden, 1844a, Bimeria Wright, 1859a, and Porpita Lamarck, 1801 are designated as valid and as nomena protecta, while seldom-used older names threatening them (the synonyms Echinochorium Hassall, 1841 and Manicella Allman, 1859a, and the homonym Porpita Soldani, 1789 respectively) are relegated to nomena oblita. Also designated a nomen oblitum is the name Pyxidium Leuckart, 1856, threatening its junior but widely used synonym Ectopleura L. Agassiz, 1862. The species name Bimeria vestita Wright, 1859a is rendered valid and a nomen protectum, while its virtually unused senior synonym Manicella fusca Allman, 1859 becomes a nomen oblitum. Hydrodendrium Nutting, 1905 is reinstated as a valid genus, distinct from Hydractinia and replacing its junior objective synonym Nuttingia Stechow, 1909. The spelling of Hydrodendridae Nutting, 1905 is emended to Hydrodendriidae, but that family name is retained as a synonym of Hydractiniidae. Usage of the familiar generic name Sphaerocoryne Pictet, 1893 is upheld by recognizing it and its former senior subjective synonym Corynetes Haeckel, 1879 as valid. The correct spelling of the family name originally founded as Olindiadae Haeckel, 1879 is taken to be Olindiidae, and spelling of the species name Solanderia misakinensis (Inaba, 1892), first established as Dendrocryne (sic) misakii, is stabilized. One new species, Stylactaria munita, is described from shallow waters at Hawaii Kai, Oahu. Lectotypes are designated for Corydendrium corrugatum Nutting, 1905 and Corydendrium minor Nutting, 1905 (=Turritopsis minor), both originally described from Hawaii. Type material of Balea mirabilis Nutting, 1905 (=Balella mirabilis), originally described from waters between the islands of Molokai and Maui, could not be located. Six anthoathecate species [Corydendrium parasiticum (Linnaeus, 1767), Bimeria vestita, Amphinema sp., Eudendrium carneum Clarke, 1882, Ectopleura viridis (Pictet, 1893), and Sphaerocoryne bedoti Pictet, 1893] are recorded from Hawaii for the first time.

The Red Sea has five species of the apogonid genus Fowleria, including F. isostigma, a Pacific Ocean species not yet known from the western Indian Ocean proper. Previously, F. isostigma was placed in the synonymy of F. punctulata (Rüppell 1838). However, the taxonomic status of the latter has not been established and in previous works it was placed in the synonymy of F. aurita or F. variegata. This paper compares Red Sea specimens identified as F. isostigma with F. variegata and with the type specimens of F. punctulata. The presence of F. isostigma in the Red Sea is established and F. punctulata is confirmed as a junior synonym of F. variegata. The holotype of F. punctulata is identified by the size given in the original description. A key to the Red Sea species of Fowleria is provided.

Commercial Harvesting

Members of the family Coralliidae, known as precious corals, are ecologically and economically important deep-sea or-ganisms. However, these organisms are currently threatened by commercial harvesting. In order to create and implementeffective conservative strategies, taxonomic knowledge of conservative targets is necessary, but unfortunately the taxon-omy of precious corals in this family is still ambiguous. This study provides a review of 15 Coralliidae species from thenorthern West Pacific region and a key to species identification. In addition, descriptions of two new species, Coralliumcarusrubrum n. sp. and C. taiwanicum n. sp., as well as a redescription of C. sulcatum Kishinouye, 1903 are included.Corallium carusrubrum n. sp. is distributed on seamounts off northeastern Taiwan. The autozooids of C. carusrubrum n.sp. are retractile and each can be fully withdrawn into the cortex thereby causing a mound on the surface which is shortand cylindrical rather than typically hemispherical; additionally, there are no long spindles in their tentacles. Coralliumtaiwanicum n. sp. is distributed in an area off southwestern Taiwan. It has special unique 8-radiates with an oval shapeand large projections. Corallium sulcatum is distributed from an area off southwestern Taiwan to western Japan. It hasbeen harvested and traded for decades, but there were no illustrations in its original description, hence a redescription of this species is provided.

The family Macrophthalmidae Dana, 1851, is one of the best represented brachyuran groups in intertidal habitats in the Persian Gulf. Nine species from two subfamilies are reported from the gulf and the adjacent Gulf of Oman, mainly inhabiting intertidal soft substrates. The subfamily Ilyograpsinae Števcic, 2005, is represented by Ilyograpsus rhizophorae Barnard, 1950, erroneously recorded as I. paludicola (Rathbun, 1909). Eight species of the subfamily Macrophthalminae Dana, 1851, have been recorded from the area, all belonging to Macrophthalmus Desmarest, 1823. Of these, M. sinuspersici Naderloo & Türkay, 2010, has recently been described and is the only species of the genus occurring on rocky shores. Macrophthalmus graeffei A. Milne-Edwards, 1873, occurs in subtidal water and is hereby recorded for the first time from the northern Indian Ocean. The remaining six species, M. dentipes Lucas, 1836, M. depressus Rüppell, 1830, M. grandidieri A. Milne-Edwards, 1867, M. laevis A. Milne-Edwards, 1867, M. serenei Takeda & Komai, 1991, and M. sulcatus H. Milne-Edwards, 1852, are important elements of the intertidal soft bottom communities. An identification key for the genus Macrophthalmus in the area is provided, and the geographical distribution of the family is briefly discussed.
