Doxomysis algoaensis, a new mysid species (Crustacea: Mysidacea) from Algoa Bay (South Africa)

Doxomysis algoaensis sp.nov. is described from Algoa Bay, South Africa where it is common in nearshore marine waters just beyond the breaker line. D. algoaensis sp.nov. is morphologically similar to D. australiensis, but can readily be distinguished by the shape and armature of the telson and the length of the exopod of the fourth male pleopod. The apical cleft is one fifth the telson length in the former species and one third the length in D. australiensis. The telson apex on each side of the cleft is also armed with five and four stout spines in the two species, respectively. In D. australiensis, the exopod of the fourth male pleopod is almost three times the length of the endopod; in D. algoaensis sp.nov., the exopod is only slightly longer than the endopod. Other distinctive features of D. algoaensis sp.nov. include the maxillary palp, which is only slightly broader than long and the greater number of spines on the endopod of the uropod.

Rostromysis bacescuii gen. et sp. nov. and Megalopsis den-ticauda gen. et sp. nov. (Crustacea -- Mysidacea) from the south-west coast of Australia

Rostromysis bacescuii gen. et sp. nov. and Megalopsis denlicaudagen. et sp. nov. belonging to the tribe Leptomysini are describedfrom the south-west coast of Australia. The characters uniqueto the genus Rostromysis are the unusually long club-shapedrostrum and the large delicate lamella-like pleopods of thefemale, thus easily distinguishing it from the allied generaTenagomysis and Doxomysis. The genus Megalopsis is closely alliedto Leptomysis, Prionomysis and Promysis but is readily distinguishablein having a short linguiform uncleft telson with a pair of medianplumose setae.     

Descriptions of five new species of Haplostylus (Mysidacea-Crustacea) from South West Australia

Five new species, Haplostylus flagelliforma sp. nov., H.similissp. nov., H.multispinosus sp. nov., H.uthupus sp. nov. and H.disparsp. nov., are described from the south-west coast of Australia.These new species are distinguishable from each other and fromthe other allied species by the structure of the pleopods ofthe male, and by the armature of the telson and the uropods.     

Ultrastructural observations on marine choanoflagellates (Choano-flagellida, Acanthoecidae) from the coast of Thailand: species of Apheloecion gen.nov

Three species of loricate choanoflagellates (Choanoflagdlida,Acanthoecidae), collected from the Andaman Sea near Phuket Island(SW Thailand), have been described and referred to Apheloeciongen.nov. (holotype: A. quadrispinum sp.nov.). All species possessa single-chambered lorica composed of one transverse costs overlaidby a limited number of longitudinal costae which converge posteriorly.Anteriorly the longitudinal costae protrude above the transversecosta as sharp pointed spines. In A. quadrispinum sp.nov. andA. pentacanthum sp.nov. the lorica is terminated by a shortposterior spine, whereas in A. articulatum sp.nov. the pedicelis much more prominent, consisting of several costal stripswhich are joined end-to-end. The species of Apheloecion appearto be most closely related to species of Calliacantha and Monocosta.None of the species described are so far known from localitiesoutside the Andaman Sea.

Some evolutionary features of bryozoans of the genus <Emphasis Type="Italic">Neotrematopora</Emphasis> Morozova and new <Emphasis Type="Italic">Neotrematopora</Emphasis> species from the Devonian of the Salair Ridge and Rudnyi Altai (Russia)

The evolution of the Neotrematopora species is shown to trend in the direction of developing stronger colonies, implemented in different ways: through changes in the diameter of apertures and thickness of walls of autozooecia, changes in the location and number of diaphragms, number of acanthozooecia and mesozooecia, and the degree to which the latter are filled. An increased development of some structural elements of the colony was compensated for by a decrease in the role of others. Based on the general direction of evolution in the genus Neotrematopora and the succession of its species changing each other in time, several phylogenetic lines in the development of the Early Devonian-Early Givetian Neotrematopora species in the Altai-Sayan folded region are outlined. During the Middle Emsian transgression the species of the Salair paleobasin invaded Gornyi Altai, and those of the Gornyi Altai invaded the Salair. New species from the Emsian (N. spinula sp. nov.) and Eifelian (N. alveolata sp. nov., N. ariadnae sp. nov.) stages of the Salair Ridge and from the Emsian Stage (N. rudnoaltaica sp. nov.) of Rudnyi Altai are described.

The correct position of flagellar insertion in Prorocentrum and description of Prorocentrum rhathymum sp. nov. (Pyrrhophyta)

For three Prorocentrum species, P. minimum (Pavillard) Schiller,P. rhathymum sp. nov., and P. triestinum Schiller, we have foundthat both flagella emerge from a single large pore. This arrangementis contrary to previous observations which suggested they arosefrom separate pores. Prorocentrum triestinum has only one anteriorpore, whereas P. minimum and P. rhathymum sp. nov. have an additionalauxiliary pore. The pores in all three species are formed bya series of small plates. The left and right valves on eachspecies can be identified by ornamentation unique to each valve.Prorocentrum rhathymum sp. nov., isolated from the planktonof Cinnamon Bay, Virgin Islands, is described. ² The Biological Laboratories, Harvard University, Cambridge,Massachusetts 02138 ³ Department of Botany, Duke University, Durham, North Carolina27706     

New species of Teratosphaeria associated with leaf diseases on Corymbia calophylla (Marri)

Corymbia calophylla is an important eucalypt species endemic to the south-west of Western Australia. It is currently in decline across its native habitat for unknown reasons but perhaps due to climate change or to the presence of a recently described canker disease caused by Quambalaria coyrecup. Few fungal leaf pathogens have been described from C. calophylla. The following paper describes two new species of Teratosphaeria from C. calophylla, Teratosphaeria calophylla sp. nov and T. rubidae sp. nov. In addition, a new epitype was designated for T. australiensis.     

Recent and Tertiary Seeds of the Nymphaeaceae sensu lato with a Revision of Brasenia ovula (Brong.) Reid and Chandler

The nine extant genera within the Nymphaeaceae s l (Water Lilies)are shown to be separable from one another on the basis of seedmorphology In particular, epidermal detail, vertical sectionof the testa and relative position of the micropyle and hilumare diagnostic for each genus These features are consideredin connection with current systematic treatments of this familyFossil seeds are reviewed at the generic level and many of theseeds previously assigned to Brasenia ovula (Brong ) Reid andChandler are shown to belong to an extinct genus of Nymphaeaceaeintermediate between the currently accepted families Cabombacaceaeand Nymphaeaceae s s They are redescribed as Sabrenia chandleraegen et sp nov. The British Tertiary fossils Brasenia spinosaChandler, Palaeonymphaea eocenica Chandler emend and ?Nymphaealiminis sp nov are described Fossil material of Carpolithesovulum Brongniart 1822a, Brasenia victoria (Casp ) Weberbauer1893, B teumeri Kirchheimer 1935, B tenuicostata Nikitin 1965and Nymphaea arethusae Grambast 1962 has been studied for comparativepurposes The use of ‘?’ before the extant genericname is advocated when all features of a fossil indicate thatit may be placed in a living genus but when certain additional,critical features of the living genus are lacking on the fossil.

Rhopalophthalmus constrictus sp. nov. and Australomysis reubeni sp. nov. (Crustacea-Mysidacea) from south-west Australian waters

Two new species of mysids are described. Rhopalophthalmus constrictussp. nov. is unique in having a well-produced triangular rostralplate, pleural plates on the anterior five abdominal somitesand prominent constriction at the distal end of the telson.Australomysis reubeni sp. nov. is distinguished by its rostrum,telson, fourth male pleopod and modified setae on the carpopropodalsegment.     

Additions to the mysid fauna (Crustacea: Mysidacea) from coastal waters of Mozambique, with descriptions of two new species

Sampling for mysid shrimps in shallow coastal waters of Mozambique provided new distribution records for Siriella brevicaudata Paulson, 1875, Gastrosaccus bispinosa Wooldridge, 1978, Gastrosaccus longifissura Wooldridge, 1978, Dioptromysis proxima Nouvel, 1964 and Anisomysis maris rubri Bãcescu, 1973. Rhopalophthalmus tropicalis sp. nov. and Gastrosaccus mozambicus sp. nov. are described for the first time. The former species is distinguished from its closest relative R. terranatalis O. Tattersall, 1957 by its much smaller size, the lack of serrations on the lateral spines of the telson, the structure and arrangement of the spines on the antennal sympod and the number of subdivisions of the propodus of the thoracic endopod. Adult males of G. mozambicus sp. nov. show affinity to G. bispinosa, but the two species are separated by the form of the two distal exopod segments on the 3rd pleopod.
