On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.     

Nothotalisia, a new genus of Picramniaceae from tropical America

A new genus of Picramniaceae from tropical America, Nothotalisia, is described. Of the three species in the genus, N. piranii and N. cancellata, are new to science. The third, N. peruviana, was originally described as Talisia peruviana in the Sapindaceae. The genus and all three species are described, illustrated, and distinguished by means of a key.     

Filibryum (Hypnaceae), a new moss genus with a new species from East Asia

Filibryum, a new genus of the family Hypnaceae, is described to include three species from East Asia. Filibryum ogatae and F. yakoushimae are transferred to it from the genus Glossadelphus, while F. deguchianum is a newly described species. The genus is distinguished by the absence of a central strand in the stem, prorate leaf cells, and heteroblastic and deciduous stem leaves. Molecular data suggest that the genus is closely related to Taxiphyllum and the phylogenetic position of the new genus in the Hypnaceae is supported by an approximately unbiased (AU) test.     

Lobatiriccardia yunnanensis,sp. nov. (Metzgeriales,Aneuraceae) from Yunnan,China

Abstract

The genus Lobatiriccardia Furuki is reported as new to China, from the Dulong River valley, Gaoligong Shan range, Yunnan Province and this material is described as a new species endemic to China, Lobatiriccardia yunnanensis Furuki & D.G. Long, the fifth known species in the genus. The differences between the new species and the other members of the genus are enumerated, along with a key to all known species of Lobatiriccardia.     

Three new species of gnathostomulida from the West Atlantic

Two new species of Gnathostomulida from Bermuda and one from North Carolina are described. All belong to the higher Bursovaginoidae with two occurring in the genus Austrognathia and one in the genus Gnathostomula. Tables of major diagnostic characters showing morphological variability within species and between previously described species in the same genus are included. Clarification in recognition of Gnathostomula jenneri and Gnathostomula brunidens is given under “Remarks on Known Species”.     

Three new species of penicillium

Three new species of microfungi belonging to the genus Penicillium Link ex Fries are described and illustrated. All but one have been isolated from the atmosphere of las Palmas, capital city of the island of Gran Canaria (Canary Islands, Spain). They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new species: Penicillium hispanicum sp. nov., Penicillium grancanariae sp. nov., and Penicillium palmensis sp. nov.     

The benthic dinoflagellate genus Amphidinium in south-eastern Australian waters,including three new species

Seventeen species of the mainly sand-dwelling genus Amphidinium are reported from south-eastern Australian waters. Three new species are described: A. boggayum, A. mootonorum and A. yuroogurrum. Additional features from previously described species are presented, including non-motile cell stages. Nine of these species are new records for Australia; however, these species are probably widespread and common. Two potentially ichthyotoxic species of Amphidinium were commonly found: A. carterae and A. cf. operculatum. A table of morphological characters is compiled as a step towards recognizing new characters with which to group species of this presently artificially defined unarmoured dinoflagellate genus.     

New England Coelogynoporidae

Eleven species of the proseriate turbellarian family Coelogynoporidae have been encountered between Cape Cod, Mass. and the southern shore-line of New Brunswick, Canada. The distributions of Coelogynopora schultzii, C. biarmata and Cirrifera cirrifera are reported. Four new species belonging to the genus Coelogynopora, one new species of Cirrifera and a species belonging to a new genus are described. Two species remain undescribed. Biological observations on a laboratory-reared colony of C. biarmata maintained since 1978 are reported.     

Revision of the genus Thambemyia Oldroyd (Diptera: Dolichopodidae) with description of a new subgenus

The genus Thambemyia Oldroyd is revised. Five species are recognized. Three new species –T. bisetosa, T. bruneiensis and T. hui– are described, and T. pagdeni Oldroyd, 1956 is redescribed. A new subgenus is founded for one new Japanese species, T. (Prothambemyia) japonica. A key to all known species of the genus is provided. Their distributions are also discussed.     

四川毛茛科二新种——乌头属一新种和唐松草属一新种

该文描述了自四川西部发现的毛茛科二新种,包括四川乌头属一新种,即泸定乌头(Aconitum ludingense W.T.Wang),此新种隶属于乌头属乌头亚属,以及四川唐松草属一新种,即狭药唐松草(Thalictrum stenantherum W.T.Wang),给出了此新种与其近缘种六脉萼唐松草之间的形态区别.     

A new genus of broad-winged moths of the family Cryptolechiidae (Acryptolechia,Lepidoptera, Gelechioidea) from southeastern Asia

The new genus, Acryptolechia (Lepidoptera, Cryptolechiidae), with the type species Cryptolechia malacobyrsa Meyrick, 1921 is described. The differences between this species and the type species of the genus Cryptolechia, Zeller 1852 (C. straminella Zeller, 1852) are shown. The genus Meleonoma Meyrick, 1914 is the closest to the new one. In addition to the type species, the new genus includes Acryptolechia facunda (Meyrick, 1910) comb. n. from India and A. torophanes (Meyrick, 1935) comb. n. from China.     

TWO NEW SPECIES OF TOLYPELLA(CHARACEAE) FROM NORTH AMERICA1,2

Two new species of the genus Tolypella (Characeae)–T. boldii Sawa sp. nov. and T. canadensis Sawa sp. nov.–were discovered in Texas, U.S.A., and Ontario, Canada, respectively. The species are recognized as additional members to the section Acutifolia because of the small and conical branchlet end cell and the oospore with a single basal impression. However, they differ from all the members previously described in the genus by the frequent and unique development of a terminal antheridium at the fertile branchlet node. A new and unexpected chromosome number of n = 8 for the genus was determined in both species, which, renders additional support to the conclusion that they represent a new taxonomic group in the section. The plants are described in detail in order to clarify some important morphological features which have been loosely interpreted by previous workers. Relationships between the new species and other members of the section are analyzed.     

Campylocentrum guarinae sp. nov. (Vandeae,Orchidaceae) from Colombia

A new species of Campylocentrum from the Colombian Andes, C. guarinae, is described, illustrated and placed within a key to Colombian species of the genus. The new species resembles C. lansbergii from which it differs in vegetative and floral characters. The main differences between these species are described and illustrated.     

A new species of <Emphasis Type="Italic">Leucocytozoon</Emphasis> Berestneff, 1904 (Apicomplexa: Leucocytozoidae) from the avian family Artamidae

A new species of the apicomplexan genus LeucocytozoonBerestneff, 1904, L. artamidis n. sp., is described from the Australian avian family Artamidae. Gametocytes and endogenous stages of the life-cycle are described together with early erythrocytic and leucocytic developing forms rarely described for species of this genus.     

An integrative approach to species delimitation in Echinodorus (Alismataceae) and the description of two new species

Summary  Taxonomy of the genus Echinodorus is partially revisited in the light of current understanding of the phylogenetic relationships of the genus. As a result of new taxonomy, the species status of some previously synonymised taxa are restored, other names are synonymised, and some nomenclatural problems unnoticed by previous authors are resolved. Two new species, Echinodorus reptilis and E. emersus are described. The subgeneric divisions of the genus are not accepted, and all subspecific taxa are either rejected or established as species. As a result, 28 species based on a phylogenetic species concept are now recognised in Echinodorus and an identification key to these species is provided.     

The Madagascan genus <Emphasis Type="Italic">Vaughania</Emphasis> is reduced to synonymy under <Emphasis Type="Italic">Indigofera</Emphasis> (<Emphasis Type="Italic">Leguminosae-Papilionoideae-Indigofereae</Emphasis>)

Summary  Eleven species comprising the Madagascan genus Vaughania are subsumed within the large pantropical genus Indigofera. Six new combinations are made; the remaining species were originally described in Indigofera.     

Monophyletic origin of Caryophyllia (Scleractinia,Caryophylliidae), with descriptions of six new species

The genus Caryophyllia Lamarck, 1816 is the most diverse genus within the azooxanthellate Scleractinia comprising 66 Recent species and a purported 195 nominal fossil species. Examination of part of the deep-sea scleractinian collection made by the Paris Museum off New Caledonia and part of the material collected by CSIRO off Australian waters revealed the occurrence of 23 species of Caryophyllia, of which six are new to science. All new records, including the new species, are described, and synonyms, distribution, type locality, type material and illustration are provided for each species. An identification key to all Recent species of Caryophyllia is presented. In addition, the validity of the genus Caryophyllia was investigated by phylogenetic analyses of a dataset consisting of partial mitochondrial 16S rRNA sequences from 12 species assigned to this genus together with seven species representing some of the most morphologically similar caryophylliid genera, and 14 non-caryophyllid species representing 14 scleractinian families. Irrespective of the method of analysis employed, all of the Caryophyllia species formed a well-supported clade together with Dasmosmilia lymani and Crispatotrochus rugosus. Although based on a subset of the Recent Caryophyllia species, these results are consistent with Caryophyllia being a valid genus, but call for a reexamination of Dasmosmilia and Crispatotrochus.
