Indo-West Pacific species of the genus Stylopoma Levinsen, 1909 (Bryozoa: Cheilostomatida)

Twenty-one species of Stylopoma Levinsen, 1909 are described and illustrated with scanning electron micrographs. S. spongites (Pallas, 1766), the type species, is redescribed from the neotype specimen and included here for completeness. A neotype specimen for S. duboisii (Audouin, 1826) and a lectotype specimen for S. viride (Thornely, 1905) are designated and 14 new species of Stylopoma are described from Indo-West Pacific material in the Recent bryozoan collections of the Natural History Museum, London.     

Notes on the genus Anoteropora (Bryozoa, Cheilostomatida)

Four species of the ascophoran 'sand-fauna'bryozoan genus Anoteropora arc now known from the Indian Ocean, and include A. magnicapitata, A. latirostris, A. inarmatu and A. otophora sp. n. Colonies are lunulitiform and anchored by basal rhizoids. The characters and distribution of all species, including fossil specimens, are described. Those of some related genera, including the Recent, east Atlantic Ascosia , and the Tertiary, European Kionidella and Stenosipora , are briefly discussed. A key to the species of Anoteropora is given.     

Some British species of Schizomavella (Bryozoa: Cheilostomatida)

Six British species of the Cheilostomatous bryozoan genus Schizomavella Canu & Bassler, 1917 are described and figured. Neotype specimens are selected for S. auriculata (Hassall) and S. linearis (Hassall), and lectotypes are selected for S. cuspidata (Hincks) and 5. hastata (Hincks). S. hastiformis Hayward and Ryland is placed in synonymy with S. linearis. S. sarniensis sp. nov. is described from several south-west British localities.     

The British species of Schizoporella (Bryozoa: Cheilostomatida)

Three new species are described in the cheilostomate bryozoan genus Schizoporella Hincks, 1877. British records of Scliizoporella dunkeri Reuss are shown to represent two previously unnamed species. Scliizoporella dunkeri is the senior synonym of the Adriatic species Schizoporella longirostris Hincks. Material of S. longirostris from British localities is referred in part to S. dunkeri and in part to a previously unnamed species.     

Some British Phidoloporidae (Bryozoa: Gheilostomatida)

Five British species of Reteporella Busk, 1884 are described and figured. A neotype specimen is selected for R. beaniana (King), and R. incognita sp. nov. is described, and distinguished from R. couchii (Hincks).     

Systematic studies on some Antarctic and sub-Antarctic Ascophora (Bryozoa: Cheilostomata)

Twenty-two species of ascophoran cheilostome Bryozoa are described and figured from Antarctic and sub-Antarctic localities. Ten new species are described in the genera Exochella, Buffonellodes and Hippadenella. Ralepria gen. nov. is introduced for Ralepria conforma sp. nov., and Trilochites gen. nov. is introduced for Escharoides biformata Waters, 1904. Five species described by Jullien (1888) and Calvet (1909) are redescribed following re-examination of type specimens.     

Multizooidal Budding in Parasmittina trispinosa (Johnston) (Bryozoa,Cheilostomata)

Two principally different wall types occur in the bryozoan colony: Exterior walls delimiting the super-individual, the colony, against its surroundings and interior walls dividing the body cavity of the colony thus defined into units which develop into sub-individuals, the zooids. In the gymnolaemate bryozoans generally, whether uniserial or multiserial, the longitudinal zooid walls are exterior, the transverse (proximal and distal) zooid walls interior ones. The radiating zooid rows grow apically to form “tubes” each surrounded by exterior walls but subdivided by interior (transverse) walls. The stenolaemate bryozoans show a contrasting mode of growth in which the colony swells in the distal direction to form one confluent cavity surrounded by an exterior wall but internally subdivided into zooids by interior walls. In the otherwise typical gymnolaemate Parasmittina trispinosa the growing edge is composed of a series of “giant buds” each surrounded by exterior walls on its lateral, frontal, basal and distal sides and forming an undifferentiated chamber usually 2–3 times as broad and 3 or more times as long as the final zooid. Its lumen is subdivided by interior walls into zooids 2–3, occasionally 4, in breadth. This type of zooid formation is therefore similar to the “common bud” or, better-named, “multizooidal budding” characteristic of the stenoleamates but has certainly evolved independently as a special modification of the usual gymnolaemate budding.     

The Recent species of Adeonella (Bryozoa: Cheilostomata) including descriptions of fifteen new species

The genus Adeonella Busk (1884) comprises 41 species, 15 of which are considered to be new to science. Adeonella lichenoides (Lamarck) is regarded as the senior synonym of A. platalea (Busk) (= A. polymorpha Busk), the type species of the genus. Adeonella is distributed throughout the Indo-West Pacific realm, the Mediterranean, and the South Atlantic Ocean. Its highest diversity is found off the east coasts of southern Africa. Thirty-one species (15 new to science) are described and illustrated, morphology and geographical distribution are discussed and a key is provided to all recognized species.     

New Indo-Pacific species of Rimosodaphnella Cossmann, 1916 (Gastropoda: Conoidea): a genus of probable Tethyan origin

The genus Rimosodaphnella Cossmann, 1916 was proposed for Murex textile Brocchi, 1814, a European Miocene–Pliocene species, and is sometimes thought to be represented in the recent fauna by three Atlantic species. Here, we assign only one Atlantic species, Pleurotoma (Drillia) morra Dall, 1881 distributed from North Carolina to Southern Brazil, to the genus and introduce three new species of Rimosodaphnella from the Indo-Pacific region. One, Rimosodaphnella solomonensis, n. sp. from the Solomon Islands, while two others, Rimosodaphnella tenuipurpurata n. sp. and Rimosodaphnella brunneolineata n. sp., from the Philippines Islands; these findings suggest that the genus may be well represented in the Indo-Pacific region.

Ecnomus of Madagascar,species without modified spur (Trichoptera: Ecnomidae)

The 11 Malagasy species of the genus Ecnomus McLachlan, 1864 that do not belong to the psychomyiellodes species group are studied. One of them (Ecnomus salgiel Malicky, 2015) was recently described from Nosy Be Island. Ten are new and described: Ecnomus felix n. sp., E. dobignyi n. sp., E. matsaboryi n. sp., E. granjoni n. sp., E. commersoni n. sp., E. menavavae n. sp., E. ikopaensis n. sp., E. rubermortis n. sp., E. evidens n. sp., and E. tendroensis n. sp. All are endemic to Madagascar. Their distributions on the island are briefly described according to ecological data.     

Liparis tsii: a new species of Orchidaceae (tribe-Malaxideae) from Guangdong,China with its phylogenetic position

Liparis tsii, a new orchid from Guangdong, China, is described and illustrated. It is compared with its closest allies: L. sasakii Hayata, L. nanlingensis H.Z. Tian & F.W. Xing, L. krameri Franch. & Sav., L. reckoniana T.C. Hsu and L. brunnea Ormerod belonging to section Liparis. Further phylogenetic study based on combined molecular data from nrITS and plastid trnL-F ascertained its phylogenetic position as L. tsii being sister to L. sasakii and L. nanlingensis. A key to identification with the allied species is provided.     

North-east Atlantic and Mediterranean species of the genus Buffonellaria (Bryozoa, Cheilostomata): implications for biodiversity and biogeography

In this study we revise the cheilostome bryozoan genus Buffonellaria Canu & Bassler, 1927 and its Mediterranean and north-east Atlantic species, thereby addressing several existing problems. First, a lectotype for the type species, Buffonellaria divergens (Smitt, 1873) from Florida, is chosen, which proves to be distinct from the European species. Second, the two hitherto established north-east Atlantic species [ Buffonellaria nebulosa ( Jullien & Calvet, 1903 ) and Buffonellaria porcellanum Arístegui Ruiz, 1987], are redescribed, which were poorly documented until now. Third, close inspection of material, collected from Spitsbergen to tropical West Africa, using scanning electron microscopy reveals that the actual number of species, all previously referred to either B. divergens or Stephanosella biaperta (Michelin, 1848), is distinctly greater in the north-east Atlantic than has been previously acknowledged. As a result, seven new species are introduced ( Buffonellaria acorensis sp. nov. , Buffonellaria antoniettae sp. nov. , Buffonellaria arctica sp. nov. , Buffonellaria harmelini sp. nov. , Buffonellaria jensi sp. nov. , Buffonellaria muriella sp. nov. , and Buffonellaria ritae sp. nov. ), whereas two are left in open nomenclature. With the increase in number of species, the extremely broad geographical range of distribution assumed for B. divergens breaks down to numerous restricted areas. However, although most species have only been reported from a single location, B. arctica sp. nov. seems to have a fairly wide distribution in the Arctic region.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 152 , 537–566.     

The recent New Zealand species of Triforis (Gastropoda: Triforidae)

Paramendax apicina Powell and Mendax attenuatispira Powell are referred to genus Triforis Deshayes; T. antepallaxa, T. blacki, and T. tui are described as new; and a species close to the South Australian Triforis epallaxa (Verco) is recorded from New Zealand waters. Paramendax Powell is transferred from the Cerithiopsidae to the Triforidae as a subgenus of Triforis. It is suggested that the Recent South African Cerithiella nonnitens Barnard is referable to Triforis.     

Australian species of Sinella (Sinella) Brook (Collembola: Entomobryidae)

Abstract  The Australian subgenus Sinella ( Sinella ) Brook is revised. Two species are recognised. A new species from New South Wales and South Australia, Sinella ( Sinella ) samueli , is described and the widely distributed species Sinella ( Sinella ) termitum Schött is redescribed based on examination of a specimen from the type series and fresh collections from a wide range of localities in south-eastern Australia. New patterns of chaetotaxy for the genus are described from these species.
