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.”

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 are retractile and each can be fully withdrawn into the cortex thereby causing a mound on the surface which is shortand cylindrical rather than typically hemispherical; additionally, there are no long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.

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.

First Descriptions

Two new species of Taeniacanthus Sumpf, 1871 (Copepoda, Taeniacanthidae) are described from filefishes (Monacanthidae) caught in the Indo-West Pacific region: T. brayae n. sp. from Pervagor melanocephalus (Bleeker) collected from five localities within the Central Indo-Pacific realm and T. mcgroutheri n. sp. from Monacanthus chinensis (Osbeck) and Paramonacanthus choirocephalus (Bleeker) caught off the Australian coast. Taeniacanthus brayae n. sp. and T. mcgroutheri n. sp. are distinguished from their congeners by the presence of an elongate terminal endopodal segment of the antenna, a spinulated terminal process and one seta on the maxillary basis, six elements on the terminal exopodal segment of legs 2–4 and an armature of II, I, 2 and II, I, 1 on the terminal endopodal segments of legs 2 and 3, respectively. Taeniacanthus brayae n. sp. can be readily distinguished from T. mcgroutheri n. sp. by having one row (rather than multiple rows) of spinules on the large pectinate process of the antenna, four setae (rather than three) on the maxillule and a 3-segmented (rather than 2-segmented) endopod on legs 2–4. New host and/or locality records for the taeniacanthids Cirracanthus monacanthi (Yamaguti, 1939), C. spinosus Dojiri & Cressey, 1987, Nudisodalis acicula Dojiri & Cressey, 1987 and Taeniacanthus aluteri (Avdeev, 1977) parasitic on triggerfishes and filefishes, as well as supplementary morphological information for the females and the first descriptions of the males of C. monacanthi, C. spinosus and N. acicula, are also included.

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.

Alpheid Shrimp

The Indo-West Pacific alpheid shrimp genus Athanopsis Coutière, 1897 is briefly reviewed. Athanopsis platyrhynchusCoutière, 1897, the type species, is reassessed using Coutière’s illustrations and morphological notes scattered throughouthis monograph of the family Alpheidae (Coutière 1899). Athanopsis brevirostris Banner & Banner, 1981, originally de-scribed on the basis of a single immature specimen missing both chelipeds, is reported and illustrated based on fresh ma-terial from Madagascar and southern Japan. Athanopsis gotoi sp. nov. is described based on two fresh specimens fromsouthern Japan, both found associated with thalassematid echiurans, and an additional, older museum specimen from In-donesia. The colour patterns of A. brevirostris, A. gotoi sp. nov., A. saurus Anker, 2011, A. rubricinctuta Berggren, 1991,and A. australis Banner & Banner, 1982, are contrasted to facilitate their identification in the field. A morphology and colour based key to all presently known species of Athanopsis is also provided.

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.

High Diversity

Eight new species of carnivorous sponges are described from southern South America, off Diego Ramírez Archipelago (south Chile): Abyssocladia diegoramirezensis, sp. nov., A. umbellata, sp. nov., Asbestopluma (Asbestopluma) bitrichela, sp. nov., A. (A.) magnifica, sp. nov., A. (A.) microstrongyla, sp. nov., A. (Helophloeina) delicata, sp. nov., Chondrocladia (Chondrocladia) schlatteri, sp. nov. and C. (Meliiderma) latrunculioides, sp. nov. Most of these sponges were sampled from an antipatharian coral collected accidentaly by demersal fisheries, which indicates an unexpected high diversity and abundance of carnivorous sponges in this area. The taxonomy and biogeography of the family Cladorhizidae is discussed, with an emphasis on cladorhizid versus phellodermid affinities of Abyssocladia, and on the possibility that species bearing either cleistochelae or arcuate chelae as the sole chelae morphotype may belong in this genus. A synthesis of the geographic as well as bathymetric distribution of cladorhizids is presented.

Two new species of the family Pontellidae, Labidocera kaimanaensis and Pontella papuaensis, are described and illustrated from specimens collected in Arguni Bay, West Papua, Indonesia. L. kaimanaensis belongs to the L. detruncata species-group, is distinguishable from other species of this group by the very elongated Ur1 (urosomite 1) and the asymmetrical P5 in the female and the Pdg5 (pediger 5) and P5 in the male. P. papuaensis does not belong to any of the known five groups of Indo-West Pacific Pontella, in having Ur1 with a beak-like posterodorsal process and almost symmetrical Re’s (exopods) of P5 in the female, a rostrum with double convex lenses, the chela of the right P5 with a bilobed thumb, and the inner margin of that chela armed with a large process, in the male. The establishment of four new species-sub-groups of L. detruncata, i.e., L. d.-cervi, L. d.-farrani, L. d.-kaimanaensis, and L. d.-sinilobata, as well as the establishment of a P. papuaensis species-group, are proposed.
