Vermeij and Wesselingh (2002: 267, figs. 3 and 4) named a small freshwater gastropod from the Pebas Formation (middle Miocene) of Peruvian Amazonia as ?Nassarius reductus new species. This name turns out to be a secondary homonym of Nassa reticulata var. reducta Dollfus, 1926 (p. 103-106), a taxon from the Pliocene of Albania. The genus name Nassa as used by Dollfus is a misused variant on the correct genus name Nassarius Duméril, 1806. Although the Peruvian species is clearly not a Nassarius in the strict sense (restricted to the marine Indo-West Pacific region) a global phylogenetic analysis of Nassariidae is needed before its proper allocation can be determined, as already noted by Vermeij and Wesselingh (2002). We here rename the Peruvian fossil as Nassarius (s.l.) wesselinghi in honor of Frank P. Wesselingh who discovered the species. We thank Richard E. Petit for pointing out Dollfus's monograph to us.

Comprehensive Study

The species of the cosmopolitan sponge genus Mycale occurring in the tropical Indo-West Pacific region and adjacent subtropical waters are reviewed taxonomically. Specimens incorporated in the collections of the Naturalis Biodiversity Center form the basis of this comprehensive study, supplemented by (type) specimens borrowed from or examined in other institutions. Specimens available numbered 351, belonging to 44 species, including 14 species new to science, Mycale (Aegogropila) prognatha sp.nov., Mycale (Carmia) amiri sp.nov., Mycale (Carmia) fungiaphila sp.nov., Mycale (Carmia) monomicrosclera sp.nov., Mycale (Carmia) tenuichela sp.nov., Mycale (Carmia) tubiporicola sp.nov., Mycale (Carmia) tydemani sp.nov., Mycale (Mycale) asigmata sp.nov., Mycale (Mycale) grandoides sp.nov., Mycale (Mycale) sundaminorensis sp.nov., Mycale (Naviculina) mascarenensis sp.nov., Mycale (Paresperella) sceptroides sp.nov., Mycale (Paresperella) seychellensis sp.nov., Mycale (Zygomycale) sibogae sp.nov. Three species, indicated by the designation ‘aff.’, were not definitely assigned to known or new species due to uncertainty of their identity. The genus Kerasemna, previously considered a junior synonym of Mycale, was revived as an additional subgenus Mycale (Kerasemna). One species, previously assigned to the genus Desmacella as D. lampra De Laubenfels is here reassigned to Mycale, subgenus at present undecided. Additionally, species previously reported from the region but not represented in our collections are briefly characterized and discussed. We propose new names Mycale (Mycale) mauricei nom.nov. for Mycale macrochela Burton (junior primary homonym of Mycale fistulata var. macrochela Hentschel) and Mycale (Mycale) bouryesnaultae nom.nov. for Mycale (Mycale) fibrosa Boury-Esnault & Van Beveren (junior primary homonym of Mycale (Aegogropila) adhaerens subsp. fibrosa Koltun). Keys to the species of each subgenus occurring in the region are provided. The opportunity of having studied this comprehensive set of species and specimens from the tropical Indo-West Pacific is taken to review and discuss the morphological and biogeographical data gathered so far on the genus Mycale. The genus currently comprises approximately 255 accepted species, with highest diversity focused in tropical Atlantic and Indo-West Pacific regions as well as in warm-temperate Mediterranean-Atlantic regions.

Abstract A new species of the cyclopoid copepod genus Paramacrochiron, P. tridentatum, which is parasitic on the rhizostome medusa, Versuriga anadyoneme (Maas, 1903), is described from Vietnam. This is the tenth species within the genus. The new species is distinguishable from other congeners by the combination of the following features: (1) female second maxillipedal segment with 3 acutely pointed processes terminally; (2) female leg 4 endopod as long as or slightly longer than exopod; (3) male maxilliped with a small, acutely pointed process at subterminal corner of the first segment and a row of relatively coarse spinules along the inner margin of the second segment. The present study most probably implies a high species diversity of Paramacrochiron in the tropical and subtropical waters of the Indo-West Pacific region.

Associated Species

A new sponge-associated species,Paraclimenaeus michaelisp. nov. from Sulawesi, Indonesia, and Singapore, is described and illustrated. The new species can be distinguished from its congenerics by: (1) the downwards curved rostrum with 2 acute dorsal teeth subdistally, (2) the absence of subdistal teeth on the fixed finger of the major second chela, (3) the pairs of dorsal telson spines at about 0.33 and 0.66 of the telson length, (4) the caudal fan sparsely setose, and (5) the second pereiopods without subdistal teeth on fixed finger. To evaluate its relationship with congenerics and species of the related generaApopontoniaandClimeniperaeus, a phylogenetic analysis based on the 16S mitochondrial gene is presented. A key for the identification of the species inApopontonia,ClimeniperaeusandParaclimenaeusis proposed.

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.

Maximum Body Size

Two new species of the deep-water spider crab genus Pleistacantha Miers, 1879, are described: P. griffini sp. nov. and P. maxima sp. nov. Pleistacantha griffini, from northwestern Australia and Indonesia, most closely resembles P. moseleyi (Miers, 1886), with which it has been confused. Pleistacantha griffini is readily distinguished from P. moseleyi based on carapace physiognomy, pereopod morphometrics and gonopod structure. Pleistacantha maxima, ranging from Japan to Australia, has been previously confused with the morphologically similar P. oryx Ortmann, 1893. The new species differs from P. oryx in numerous features, the most striking being a maximum body size exceeding twice that of P. oryx.

Antennular Peduncle

A new species of hippolytid shrimp, Hippolyte ngi n. sp., is described and illustrated based on specimens collected from the Indo-West Pacific region. The new species clearly belongs to the ‘Hippolyte ventricosa H. Milne Edwards, 1837’ species complex, but is distinguished from its congeners by the dactylus of the last three pereiopods, the position of the hepatic spine, the proportions of the segments of the antennular peduncle, and other subtle but constant features.

High Diversity

Within the family Archaeobalanidae, the sponge-inhabiting barnacles include species from the subfamilies Acastinae and Bryozobiinae as well as from the genus Membranobalanus in the subfamily Archaeobalaninae. Members of these groups are obligatory symbionts of poriferans, but the Acastinae can also be found in association with alcyonaceans and antipatharians. Acasta sulcata Lamarck, 1818, is one of the most widely reported sponge-inhabiting barnacle species, with numerous records across the Indo-West Pacific region revealing significant morphological variation. A combined morphological and molecular approach has revealed high diversity in recent collections of sponge-inhabiting barnacles in Taiwan and Australia, and four new species, namely Acasta aspera sp. nov., Acasta huangi sp. nov., Acasta radenta sp. nov., and Acasta undulaterga sp. nov., have been described here. All four species are morphologically close to A. sulcata, and the morphological similarity between these proposed species has led to the proposal of a “sulcata species complex.”

A New Species

A new species of stomatopod crustacean, Oratosquillina nordica sp. nov. is described from the Indo-West Pacific region (type locality: Taiwan). It is most similar to O. quinquedentata (Brooks, 1886), with which it has been confused. Oratosquillina quinquedendata is presently known only from the southern hemisphere, and most of its northern hemisphere records are referable to O. nordica. Records of O. quinquedentata from India and Sri Lanka require confirmation, possibly representing a third species. A key to the species of Oratosquillina is provided.
