Based on plankton samples collected in 1970 and on a survey of the literature, the Australian members of the genus Palmeria and of the family Lithodesmiaceae are critically listed or described. Both species of Palmeria are new for the Australian region, as are one species each of Lithodesmium and of Ditylum, two species of the genus Lithodesmioides, one species plus one variety of Bellerochea, as well as one species and one form of Neostreptotheca. Lithodesmium duckerae, Lithodesmioides polymorphum and L. minutum, Ditylum buchananii, Bellerochea horologicalis var. recta and Neostreptotheca torta and its fo. triangularis are described for the first time. Palmeria ostenfeldii, a species associated with an epiphytic ciliate, is sep- arated from P. hardmaniana. In Ditylum brightwellii, the proportion of thecae with the slotted versus the fimbriate form of the marginal ridge is shown to be probably influenced by the ambient water conditions. In the same species, the ontogenies of the resting spores (including germi- nation) as well as of the gametes are described. Lithodesmioides presents new instances of fissipariety (split wall character) in both of its species. 'Simple pores', which have recently been demonstrated by Li and Volcani to be distinct in origin from areolae, are common in all described species of Lithodesmium, Lithodesmioides and Ditylum in two forms as either 'branching point pores' or 'intracostal pores'.

We present a new marine benthic diatom genus Cymatosirella gen. nov. The genus belongs to the family Cymatosiraceae and has been assigned to the subfamily Extubocelluloideae on the basis of ultrastructural cell wall features. It has isovalvate cells with undulate valves and is characterized by the absence of tubular processes and the occurrence of hollow spines which are observed for the first time in the Cymatosiraceae. The new genus contains four species, two of which are transferred from the genus Cymatosira, viz. Cymatosirella capensis comb. nov. and Cymatosirella minutissima comb. nov., and two which are new to science, viz. Cymatosirella benguelensis sp. nov. and Cymatosirella taylorii sp. nov. Cymatosirella capensis is chosen as the generitype. The new genus includes a group of very small taxa inhabiting the intertidal zone of the Atlantic Ocean with three species in South Africa and one in Europe. C. capensis was originally described by Giffen from Langebaan Lagoon (a shallow marine inlet in the southern part of Saldanha Bay, Western Cape Province), on the basis of light microscopy only, and has to date only been illustrated by line drawings. C. minutissima, so far only known from the Westerschelde estuary (The Netherlands), has previously been documented in more detail using both light and electron microscopy. Here, we present the results of detailed light and electron microscopical investigations of C. capensis, both from its original type material and from recently collected samples from the type locality and neighboring littoral areas in the Western Cape Province, and of the new species C. benguelensis and C. taylorii, also from Western Cape localities. All species are compared with similar small taxa belonging to the Cymatosiraceae, subfamily Extubocelluloideae.

A new genus of lichenized fungi of the family Porinaceae is described, known from Costa Rica and Brazil. Flabelloporina Sobreira, M. Cáceres & Lücking is a thus far monospecific genus with an isolated position of its only species in the family, morphologically different from all other genera in Porinaceae. The genus is characterized by the production of numerous, flabelliform squamules on the surface of the thallus, together with black perithecia and transversally septate ascospores (with three septa in the only species). The new combination Flabelloporina squamulifera (Breuss, Lücking & Navarro) Sobreira, M. Cáceres & Lücking is proposed, based on Porina squamulifera Breuss, Lücking & Navarro, and the species is for the first time reported from Brazil.

The family Anthomyzidae (Diptera: Acalyptrata) is recorded from China for the first time based on 11 species, 6 of them new to science. A distinctive new genus Marshallya gen. nov. is described, based on single peculiar species, M. platythorax sp. nov. (both sexes) from Sichuan. Other new species, viz. Amygdalops sevciki sp. nov. (Hainan I.) (both sexes), Epischnomyia tkoci sp. nov. (Sichuan) (male only), Anthomyza ornata sp. nov. (Sichuan) (female only), Anthomyza sulphurea sp. nov. (Yunnan) (both sexes) and Arganthomyza hyperseta sp. nov. (Shaanxi) (male only) are described and illustrated in detail. Male-female association of two Amygdalops species is clarified by means of molecular barcoding and the female of A. bisinus Roháček, 2008 is correctly identifi ed and described. Relationships of all these taxa are discussed. Five species, viz. Amygdalops bisinus (Hainan I.), Epischnomyia merzi Roháček, 2009, Anthomyza cuneata Roháček, 1987, Anthomyza trifurca Sueyoshi & Roháček, 2003 (all from Sichuan) and Arganthomyza versitheca Roháček, 2009 (Shaanxi, Sichuan) are new additions to the Chinese fauna of Anthomyzidae. DNA sequences of the barcoding region of COI have been obtained for 3 species, Amygdalops bisinus, Amygdalops sevciki and Marshallya platythorax. Biology and distribution of all 11 species are discussed. First photographs of living Anthomyzidae from East Asia are presented. Based on knowledge of Anthomyzidae from neighbouring areas the diversity of the Chinese fauna of the family is estimated to include 50-60 species.

Echinoderms of the Middle Ordovician Platteville and lower Galena Groups of north-central Illinois and south-central Wisconsin are represented by at least seven classes including the Homoiostelea, Cystoidea, Crinoidea, Stelleroidea, Edrioasteroidea, Cyclocystoidea, Echinoidea, and possibly Holothuroidea. The most abundant and diverse echinoderms are monocyclic and dicyclic inadunate and camerate crinoids, of which the cupulocrinids and glyptocrinids are best represented. Thirteen new species and one new genus of crinoids are described:Cremacrinus guttenbergensis, Anulocrinus forrestonensis, Isotomocrinus minutus, Carabocrinus oogyi, Dendrocrinus? springeri, Merocrinus britonensis, Cupulocrinus plattevillensis, C. molanderi, Reteocrinus rocktonensis, R. spinosus, Traskocrinus mahlburgi(n. gen. et sp.),Rhaphanocrinus buckleyi, Glyptocrinus charltoni, andG. pustulosis.One new species of rhombiferan cystoid,Coronocystis durandensis, is also described. Echinoids of the family Bothriocidaridae (Bothriocidaris solemin. sp. andNeobothriocidaris templetonin. sp.) are reported for the first time from North America and appear to be the earliest recorded occurrence. Remains of a third bothriocidarid characterized by coalesced podial pores have also been discovered. Light and scanning electron microscopy of well preserved cyclocystoid specimens reveal a number of previously undescribed morphologic features of the central disc and submarginal ring that may shed some light on their functional morphology.Cupulocrinus gracilisRamsbottom from the Upper Drummuck Group Starfish Bed at Thraive Glen near Girvan, Scotland, is here reassigned toC. drummuckensisn. sp.Echinoderms are associated with an abundant and diverse fauna consisting largely of suspension feeders, primarily strophomenid and orthid brachiopods and trepostome and cryptostome bryozoans. Other common groups include corals, trilobites, sponges, and mollusks. Filamentous brown, foliose red and siphonaceous green algae are associated with the fauna at some localities.Carbonate rocks of both the limestone and dolostone facies of the Platteville (Briton, Walgreen and Forreston Members) and lower Galene Groups in the study area consist primarily of abundant shelly invertebrates occurring as whole and broken, unabraded, commonly articulated remains “floating” in a calcisiltite matrix that is highly bioturbated. Carbonate sediments appear to have been deposited in a near-to below wave base, highly stable, open marine environment characterized by low depositional slopes, good circulation and low terrigenous influx.

Ten taxa of marine diatoms from SE. or NE. Australia are described or redescribed, and their characters are supplemented by fine-structural and developmental data. One genus (Pseudoguinardia von Stosch), one species (Pseudoguinardia recta von Stosch), and two varieties (Odontella retiformis var. trigona von Stosch and Haslea gigantea var. tennis von Stosch) are newly described. Six other taxa [Coscinodiscus alboranii Pavillard, C. concinniformis Simonsen, Dactyliosolen blavyanus (Peragallo) Hasle, Rhizosolenia phuketensis Sundstrom, Haslea gigantea (Hustedt) Simonsen, and H. wawrikae (Hustedt) Simonsen] are new to the Australian flora. Gross and fine-structural characters are added to the descriptions of the world-wide and common R. stolterfothii (Stolterfoth) Peragallo and of the non-Australian Odontella retiformis var. retiformis von Stosch in order to bring them on a level of detail sufficient for their comparison with R. phuketensis or the new variety, respectively. The new species, although overlooked up to now, as well as C. alboranii and probably R. phuketensis, seem to be distributed world-wide in warmer neritic waters.

It is reported that Gaudichaud was correct in describing, under Brachycome Cass., three species, B. triloba, B. dentata and B. spathulata. Reference is made to the nomenclatural status of these species in accordance with the results of a revision of Brachycome by Davis (1948). De Candolle erred in transferring the species to Vittadinia A. Rich, for which the New Zealand V. australis is the type. Reasons are given for regarding V. triloba (Gaudich.) DC. as synonymous with V. australis var. dissecta Benth., and the variety is raised to specific rank. Included with V. australis and V. dissecta in Vittadinia s. str. (i.e. in Vittadinia subgenus Vittadinia) are V. cuneata DC. (a name which can be applied to a complex group of taxa widespread in southern and eastern Australia) and a further 17 species of which the following are new: V. cervicularis (with four varieties), V. constricta, V. condyloides, V. decora, V. eremaea, V. humerata, V. nullarborensis, V. pustulata, V. simulans and V. sulcata, while V. gracilis (J. D. Hook.) N. Burbidge and V. australasica (Turcz.) N. Burbidge are new combinations. V. scabra DC. and a group of taxa which have been referred to it or, incorrectly, to V. macrorhiza (DC.) A. Gray have been placed in a new subgenus of Vittadinia under the name Peripleura. Within this subgenus nine species are recognized: V. scabra DC., V, hispidula F. Muell. ex A. Gray (with two varieties), and the new species V. arida, V. bicolor, V. diffusa, V. obovata, V. sericea, V. spechtii (with two varieties) and V. virgata. With the exception of V. australis which is endemic to New Zealand and V. simulans, a New Caledonian species, all are endemic to Australia; however, V. hispidula has been reported for New Caledonia where it is deemed to be an alien and V. gracilis and possibly V. muelleri appear to have become naturalized in New Zealand. V. brachycomoides (F. Muell.) Benth. becomes the type of a new genus, Camptacra, with two species, both distributed in northern and north-eastern Australia. Eurybiopsis DC. is reinstated, with its single species, E. macrorhiza DC., found only in northern Australia.

The status of two supposedly myrmecophilous Australian 'Glyptoma' species described by A. M. Lea is reviewed, and lectotypes designated for both species. A new genus, Myrmelibia, is proposed for Glyptoma kingi Lea of south-eastern Australia. This genus is not related to Glyptoma or Thoracophorus, but belongs near the genera Eulibia, Heterotrochinus and Holotrochidius of the Oriental-Indian Ocean region. New records confirm that M. kingi is one of the few truly myrmecophilous osoriines, probably host-specific with Zridomyrmex nitidus Mayr (Hymenoptera : Formicidae : Dolichoderinae). Glyptoma myrmecophilum Lea is transferred to the genus Thoracophorus as a senior synonym of T. quadricostatus Bernhauer (new synonymy); present evidence suggests it is free-living and subcortical, not myrmecophilous. A key to all 16 genera of Osoriinae (sensu Blackwelder) known to occur in Australia is presented, along with the names, distribution and microhabitat of Australian species included in each genus. Four genera (Allotrochus, Arpagonus, Espeson, and Saegerius) are reported from Australia for the first time, each based on undescribed species from northern Queensland.

Steringovermes notacanthi, a new genus and species of fellodistomine digenean, is described from the deep-sea spiny eel Notacanthus bonaparte from below 1,000m depth in the north eastern Atlantic. It differs from other related genera in the unique combination of a V-shaped excretory vesicle, multilobate, mainly post-testicular ovary and extensive vitelline fields extending into both the foreand hindbody. In addition, the fellodistomine Olssonium turneri Bray & Gibson, 1980 is reported for the first time from a fish not of the genus Alepocephalus, namely the alepocephalid Narcetes stomias.

The varying concepts of Janirellidae Menzies, 1956 are outlined, including its rejection by several authors. The view of Wilson and Wägele of Janirellidae being a valid family comprising Janirella Bonnier, 1896 and presumably Dactylostylis Richardson, 1911 (= Spinianirella Menzies, 1962) is accepted. Diagnoses of the Janirellidae subsequent to Menzies’ original one were based on the inclusion of a diverse range of genera now recognised as not belonging in that family. A new diagnosis of Janirellidae is presented based on the inclusion of Janirella, Dactylostylis, and a new genus Triaina with two new species, T. isodonte and T. makridonte, from south-eastern Australia. The latter species represents the shallowest record (80 m) of the otherwise predominantly deep-water family. All species in the family are listed in an appendix, with area of type locality and depth range.
