Raphidrilus harperi sp. nov., is described from the Gulf Intracoastal Waterway (GIWW) in Venice, Florida from sediments consisting of coarse sands and shell hash. Raphidrilus hawaiiensis sp. nov., is described from Oahu’s shallow waters and inhabits a successful invasive alga in Waikiki and sandy sediments adjacent to ocean outfalls in Barbers Point and Sand Island, off Honolulu. The genus Raphidrilus is emended, the distinctness between the genera Raricirrus and Raphidrilus is confirmed and keys to all recognized genera of Ctenodrilidae and species of Raphidrilus are given.

The study presents a review of the Dendrochirotida species from shallow waters of the northeastern coast of Brazil. A total of 1,268 specimens were analyzed and 24 species were recorded, which were classified into 16 genera of Cucumariidae, Psolidae, Phyllophoridae, and Sclerodactylidae. Detailed descriptions and figures of the taxonomic characters are provided to facilitate species identification. Notes on morphological variation, geographic distribution, and habitat are also provided. We suggest two new species for science, Thyone brasiliana sp. nov. and Havelockia nietae sp. nov., the new combination Parathyone braziliensis (Verrill, 1868) and the first record of Euthyonidiella trita (Sluiter, 1910) for the Brazilian coast. The bathymetric ranges are expanded for Coronatum baiensis, Euthyonidiella trita, Stolus cognatus, and Thyonidium seguroensis.

Two New Species

Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates. Key words: chitons, Leptochiton, Terenochiton, new species, the Philippines, Japan, Papua New Guinea. Описаны два новых вида семейства Leptochitonidae, Leptochiton pumilus sp. nov. и Terenochiton nomurai sp. nov. из тропических и субтропических мелководий западной Пацифики. L. pumilus c Филиппин и Папуа – Новой Гвинеи имеет сетчатовидную скульптуру на раковине, что является довольно редким признаком в этом роде. В этом роде только три вида известны до настоящего времени в тропических мелководьях, в противоположность более чем 130 другим современным видам, которые живут в глубоких холодных водах и в высоких широтах. T. nomurai из островов Рюкю является вторым представителем рода Terenochiton Iredale, 1914, который был недавно восстановлен для Leptochiton norfolcensis (Hedley et Hull, 1912) и характеризуется наличием рудиментов инсерционных пластинок на всех щитках. T. nomurai сходен с типовым видом рода, но отличается расположением пор эстетов на зернах тегментума и менее развитыми рудиментами инсерционных пластинок. Ключевые слова: хитоны, Leptochiton, Terenochiton, новые виды, Филиппины, Япония, Папуа Новая Гвинея.

A new genus and two new species of stoloniferous octocorals (Alcyonacea) within the family Arulidae are described based on specimens collected from Okinawa (Japan), Palau and Dongsha Atoll (Taiwan).Hanagen. n. is erected within Arulidae.Hanahanagasasp. n.is characterised by large spindle-like table-radiates andHanahanatabasp. n.is characterised by having ornamented rods. The distinction of these new taxa is also supported by molecular phylogenetic analyses. The support values resulting from maximum likelihood and Bayesian inference analyses for the genusHanaand new speciesH.hanagasaandH.hanatabaare 82/1.0, 97/1.0 and 61/0.98, respectively.Hanahanagasasp. n.andHanahanatabasp. n.are the first arulid records for Okinawa, Palau, and Dongsha Atoll, and represent species of the second genus within the family Arulidae.

Two new species of Mooreonuphis, a genus best known from the coasts of the Americas, are described from Australia, bringing the number of recognized Mooreonuphis species to 23. Mooreonuphis ariasi n. sp. was collected from off Sydney to Wollongong, New South Wales in sandy sediments, in depths of 25–50 m and M. wilsoni n. sp. in the Bass Strait and Tasmania, in 89–130 m. The two new Australian species are among the smallest and the only known abranchiate species in the genus. The summer collections of M. ariasi n. sp. contained a large number of brooders with their young undergoing asynchronous direct development in the parental tube. Nothing is known about the development of M. wilsoni n. sp.

Mixed Batch

A mixed batch of sea cucumbers tentatively labelled as ?Thyone or ?Havelockia species was obtained on loan from the Natural History Museum, United Kingdom (NHMUK) for identifications and records. The material dates back to 1850 and originates from shallow waters from various parts of the world. The material includes two new species and one new subspecies which have already been described in an earlier paper (see Thandar, 2017). The remaining specimens comprise a few known or poorly known nominal species and several indeterminate forms. This paper describes the known species while adding some useful information about them. Of the indeterminate species included are several specimens most belonging to the genus Thyone or Havelockia which, because of their incompleteness and absence of ossicles, are not identified beyond their suspected genus or species.

Ordinal Level

The discovery of two diminutive and very distinct ibliform barnacles from shallow waters off northern New Zealand and northeastern Tasmania provides an opportunity to re-evaluate the Iblidae, the most primitive of the living thoracicans. These are retained within the Superorder Thoracica, but are distinguished at ordinal level from the remainder of the Pedunculata s.l. The resultant new order, the Ibliformes nov., comprises barnacles with predominantly chitinous rather than calcareous capitular plates; two families are recognized, the Iblidae s.s., comprising two subfamilies, the Iblinae (Ibla s.s.) and the Neoiblinae nov. (Neoibla gen. nov.), and the Idioiblidae nov. comprising the Idioiblinae nov. (Idioibla gen. nov.) and the Chaetolepadinae nov. (Chaetolepas Studer, 1889 and Chitinolepas gen. nov.). The monotypic Chitinolepas further highlights the high endemism and relict nature of the New Zealand marine fauna in particular and the southern hemisphere in general. On the basis of morphology and, where possible, genetic and larval work, it is recommended that the remainder of the stalked thoracicans be divided between three new orders, the †Cyprilepadiformes, Ibliformes, Lepadiformes and Scalpelliformes.

Celleporina parvula, a species present in shallow waters along the NW African coast, is re-described from its original material. Celleporina fragilis, only known from the Canaries, and Celleporina derungsi, from south Portugal, are newly reported from the Gorringe Bank and NW Iberian Peninsula respectively. Two new species are described: Celleporina algarvensis n. sp., from south Portugal, and Celleporina mediterranea n. sp., from NW Mediterranean. The structure of the ooecium and its tabula, and the structure of the frontal wall in the genus Celleporina are discussed in the light of new observations.

Taxonomical Study

The so far monotypic genus Sibogella Billard, 1911 is revised based on literature data. Its type species, S. erecta Billard, 1911, is thoroughly redescribed and illustrated, and accounts on two new congeners, S. flabellata sp. nov. from shallow waters of Indonesia and S. spissa sp. nov. from deep waters of New Caledonia, are provided. Single- (16S rRNA) and multi-locus (concatenated 16S, 18S, and 28S rRNA) phylogenetic assessments of the Plumulariidae, including newly-sequenced Sibogella material, supplement the alpha-taxonomical study.
