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.

The hydrobiid genus Islamia Radoman, 1973 (Gastropoda: Hydrobiidae) comprises 47 species known from the Mediterranean region of which most are distributed in the west and central part, whereas 11 species are known from the Balkans. In this article we described two new Islamia species from Greece. The type localities of four Islamia species hitherto known from Greece are presented on a map.

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.

AbstractTwo new species of Eurytoma Ill. are described, viz. E. oliphantis n.sp. from Sudan, Africa, reared from Eragrostis tremula and E. asphodeli n.sp. from the Mediterranean region, Ibiza, reared from the seed capsule of Asphodelus microcarpus. The latter species belongs to the robusta-group and some taxonomical notes including a key and figures on this group are presented. It seems as if both carnivorous and herbivorous species occur in the robusta-group.

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.

Two new species of the genus Knipowitschia, Knipowitschia byblisia sp. nov. and Knipowitschia caunosi sp. nov., are described from the coastal Lake Köycegiz, southwest Turkey. Knipowitschia byblisia sp.nov. is placed in a group of species with reduced cephalic lateral-line canals and reduced squamation. This species is characterized by the presence of axillary and caudal peduncular patches of scales, by a distinct reduced head canal system with only the postorbital section of the supraorbital canal developed and with longitudinal and transversal rows of free neuromasts in the interorbit. Knipowitschia caunosi sp. nov. is placed in a group of species with a fairly complete head canal system and with scales continuously extending along lateral midline from the axilla to the caudal peduncle. This species is characterized by long transverse rows of free neuromasts on the nape and on the cheek, by a characteristic pattern of the preorbital series of free neuromasts with the anteriormost row lacking and with a reduced number of transverse suborbital rows. Both species are isolated and their distributions restricted to a small brackish lake in the west of the Anatolian south coast. This record represents the southern and easternmost of the genus Knipowitschia in the Mediterranean region. The origin of these two species is discussed.

Here we describe eight specimens of Japanese precious coral (Octocorallia: Coralliidae) collected and identified byKishinouye over one hundred years ago, and recently rediscovered in the collections at the USNM, SmithsonianInstitution. Although Kishinouye identified four of the specimens he sent to the Smithsonian as Corallium elatius (Ridley,1882), two of them represent two new species which we describe: Corallium uchidai sp. nov. and C. gotoense, sp. nov.Kishinouye did not designate any type material for the species he described in his publications nor did he ever mentionsending any specimens to the Smithsonian Institution. Because his original material remains missing, we here selectneotypes from the Smithsonian material for three of his species: Corallium konojoi Kishinouye, 1903; Pleurocoralliuminutile Kishinouye, 1902 and C. japonicum Kishinouye, 1903. In this study, thanks to advances in computer technologyand software, we have been able to quantify and thus improve the vague descriptions of sclerite numbers found in pastliterature such as “few” or “many”. Our goal in reporting percent composition data for each kind of sclerite is to help to make species identifications easier for non-specialists.

The genus Microcostatus was described for the first time by Johansen & Sray in 1998. They established a new genus in the family Naviculaceae for Navicula krasskei. Subsequently, Lange-Bertalot proposed the transfer of further species from the genus Navicula to the Microcostatus. Species determination is very difficult using light microscopy since species are small and very similar to each other, and only ultrastructural features allow their placement in the genus. The aim of this paper was to describe morphologically and ecologically two new species of the genus Microcostatus from aerial habitats in Germany and Poland and compare their morphologies with the original gathering of Navicula egregia. Polish material was collected once a month from April to November 2013 at two sampling sites located in cultivated fields. For comparison, German original material from the Hustedt Collection was also observed. During this study, Microcostatus aerophilus sp. nov. and M. edaphicus sp. nov. were described, and M. egregius was also illustrated and discussed in detail. The species mentioned are very similar to each other under light microscopy. They differ slightly in dimension and number of striae. Only SEM observations showed morphological differences, such as the presence of conopeum or pseudoconopeum.
