Dransf. and two species belong to the genus Ravenea: R. beentjei Rakotoarin. & J. Dransf. and R. hypoleuca Rakotoarin. & J. Dransf. Despite the fact that most of these species have been recorded from protected areas that are difficult to access in the eastern region of Madagasacar, they are all threatened. Based on IUCN categories and criteria, seven are Critically Endangered and seven are Vulnerable.     

中国算盘子属(叶下珠科)一些种的分类学处理

算盘子属(Glochidion J.R.G.Forst.)是叶下珠科(Phyllanthaceae)叶下珠族(Phyllantheae)中一个分类极为困难的类群。基于广泛野外考察与馆藏标本查阅,对中国该属部分物种进行分类学处理。其中,长柱算盘子[G.khasicum(Müll.Arg.)Hook.f.]与倒卵叶算盘子(G.obovatum SieboldZucc.)在中国的分布予以排除,菲岛算盘子[G.philippicum(Cav.)C.B.Rob.]在中国被发现仅分布于台湾地区;G.bodinieri H.Lév.,G.pseudo-obscurum var.glabrum Pamp.与G.pseudo-obscurum var.lanceolatum Pamp.这三个名称被处理为湖北算盘子(G.wilsonii Hutch.)的新异名;G.vaniotii H.Lév.被排除在算盘子属外,并接受为芸香科臭常春(Orixa japonica Thunb.)的异名。另外,对G.khasicum(Müll.Arg.)Hook.f.,G.obovatum SieboldZucc.,G.philippicum(Cav.)C.B.Rob.,G.pseudo-obscurum var.lanceolatum Pamp.及G.wilsonii Hutch.这五个名称进行了后选模式的指定。     

Striking autapomorphic evolution in Physotheca J.J.Engel & Gradst. (Marchantiophyta: Lophocoleaceae) blurred its actual relationships with Leptoscyphus Mitt.

Abstract

The taxonomic status and phylogenetic position of the monotypic liverwort genus Physotheca J.J.Engel & Gradst., including P. autoica J.J.Engel & Gradst. endemic to Ecuador, are inferred from phylogenetic analyses of two cpDNA loci. The results indicate that the genus is nested within Leptoscyphus and the new combination, L. autoicus (J.J.Engel & Gradst.) Vanderp. & Gradst., is made. This indicates, along with an increasing body of evidence, that extreme morphological transformations can obscure the phylogenetic signal present in morphological data.     

Occurrence and chemical diversity of the genus Bryoria in the Sučí Potok Valley, Veporské Vrchy Mountains (Central Slovakia)

Four species of the genus, Bryoria were found in the Sučí Potok Valley: B. capilaris (Ach.) Brodo & D. Hawksw., B. fuscescens (Gyeln.) Brodo & D. Hawksw., B. implexa (Hoffm.) Brodo & D. Hawksw., B. nadvornikiana (Gyeln.) Brodo & D. Hawksw. The most common species in the valley was B. implexa. Four chemotypes of this lichen were recognized.     

A new and a rare parasitic copepod from fishes of Kuwait

Summary A new lernaeopodid copepod, Sparidicola papilliferens n.g., n. sp., is described from Acanthopagrus latus (Pisces: Teleostei) taken in Kuwait. This species is designated as a type of its genus, to which is transferred a second species, originally described as Brachiella lithognathae Kensley & Grindley, 1973, renamed Sparidicola lithognathae (Kensley & Grindley 1973) n. comb. A new name, Neobrachiella pillaii nom. nov., is proposed for Brachiella indica Pillai, 1968. The original name is preoccupied by Brachiella indica Tripathi, 1962, which is also transferred to the genus Neobrachiella Kabata, 1979, as N. indica (Tripathi, 1962) n. comb.     

Occurrence of some Glomales in Finland

By using trap plants, 17 species of arbuscular mycorrhizal fungi (AMF) belonging to the order Glomales were identified in 266 soil samples collected in the period 1987–1989. Of the identified isolates, 87.1% belonged to the genus Glomus Tulasne & Tulasne, 8.5% to Acaulospora Gerdemann & Trappe, 4.1% to Scutellospora Walker & Sanders and 0.3% to Entrophospora. Of the individual species identified, Glomus hoi Berch & Trappe was the most frequently identified, followed by G. fistulosum Skou & Jakobsen and G. mosseae (Nicol. & Gerd.) Gerdemann & Trappe. Only small differences in AMF trapping ability were observed between the four trap plants used, Trifolium pratense L., Zea mays L., Allium cepa L. var. cepa and Fragaria x ananassa Duch. T. pratense was chosen for further study because it had the highest AMF sporulation index in trap cultures and it also performed better than the other plants when grown in soils with different physical and chemical properties. The proportion of soil samples where AMF were identified decreased from close to 100% in the southern and central parts of Finland to about 50% in northern Finland.     

Taxonomic notes on African Orthotrichaceae I. New synonymy in Macromitrium

New synonymy and distribution records for the genus Macromitrium Brid. in sub-Saharan Africa are presented. Seven names are placed in synonymy, reducing the number of accepted taxa for Macromitrium in sub-Saharan Africa to 33. Macromitrium anomodictyon Cardot was found to be conspecific with M. serpens (Bruch ex Hook. & Grev.) Brid.; M. mauritianum Schwägr. and M. sanctae-mariae Renauld & Cardot are placed in synonymy with M. subtortum (Hook. & Grev.) Schwägr. and M. belangeri Müll.Hal., M. seriatum Paris & Broth., M. bequaertii Thér. & Naveau and M. trollii Dixon in Herz. are all placed in synonymy with M. sulcatum (Hook.) Brid. subsp. sulcatum. The precise lectotypification is implemented for six species within the genus. Macromitrium chloromitrium (Besch.) Wilbraham and M. orthostichum Nees ex Schwägr. are reported new to Tanzania and M. chloromitrium new to continental Africa.     

A revision of the moss genus Sciaromium (Mitt.) Mitt. I. General remarks and the section Aloma Dusén

Abstract

The generic name Sciaromium (Mitt.) Mitt. that was originally used as a sectional epithet in Leskea is synonymous with Echinodium Jul E. madeirense Jur. [= E. spinosum (Mitt.) Jur.] is selected as the lectotype of the genus Echinodium. A historical review of taxonomic and nomenclatural problems in Sciaromium is provided and taxa that had previously been excluded from this genus are briefly discussed. Sciaromium flavidulum Dusén is a Eurhynchium and the combination E. flavidulum (Dusén) Ochyra is made. Sciaromium sect. Aloma Dusén is synonymous with Eurhynchium since E. flavidulum serves as the type species of this section. The taxonomic position of S. gracile Dusén is discussed and this species is considered synonymous with Amblystegium chilense Lor., which is transferred to Pseudoleskea and the appropriate new combination P. chilensis (Lor.) Ochyra made. Type specimens of S. bellii Broth., S. elimbatum Broth. & Watts and S. forsythii Broth. in Broth. & Watts are briefly described and illustrated; these species are reduced to synonymy with the polymorphic Cratoneuropsis relaxa (Hook. f. & Wils.) Fleisch. in Broth.     

A poecilostome copepod parasitic in a scleractinian coral in the moluccas

Wedanus inconstans, n. gen., n. sp., a lichomolgid copepod living in the polyps of the reef coral Goniopora tenuidens (Quelch), is described from Halmahera in the Moluccas. The genus is apparently related to Xenomolgus Humes & Stock, 1972.     

A new genus and species of quill mites (Acari: Syringophilidae) from a king bird-of-paradise <Emphasis Type="Italic">Cicinnurus regius</Emphasis> (L.)

Neoperisterophila regiusi n. g., n. sp. is described from the quills of Cicinnurus regius (L.) (Passeriformes: Paradisaeidae) from New Guinea. This new genus belongs to the Peristerophila generic group. It differs from other four genera of this group, Peristerophila Kethley, 1970, PsittaciphilusFain et al., 2000, Castosyringophilus Bochkov & Perez, 2002 and Terratosyringophilus Bochkov & Perez, 2002 by the absence of the propodosomal and hysterosomal shields in the females.     

<Emphasis Type="Italic">Tabaroa</Emphasis>, a new genus of Leguminosae tribe Brongniartieae from Brazil

A new genus of Leguminosae in tribe Brongniartieae is proposed based on a new species endemic to the Caatinga of Bahia state. The new genus is named as Tabaroa L. P. Queiroz, G. P. Lewis & M. F. Wojc. and the new species as Tabaroa caatingicola L. P. Queiroz, G. P. Lewis & M. F. Wojc. A phylogenetic study of the Brongniartieae based on nuclear rDNA ITS and plastid matK sequences supports a closer relationship between Tabaroa and Harpalyce Moc. & Sessé than to the two South American genera Poecilanthe Benth. and Cyclolobium Benth., which are more similar morphologically. Optimisation of selected morphological characters on one of the most parsimonious trees indicates that the sessile ovary and the explosive pollen presentation are putative synapomorphies of the Tabaroa-Harpalyce clade. The genus Tabaroa may be diagnosed by the absence of peltate glandular trichomes; leaves imparipinnate, exstipellate and with opposite leaflets; flowers sessile, not resupinate, grouped in panicles; anthers apiculate; and fruit indehiscent. The only known species inhabits areas of arboreal caatinga on sandy soil in southwestern Bahia, near the boundaries of Dom Basílio and Livramento de Nossa Senhora municipalities.

A revision of Hexacanalis Perrenoud, 1931 (Cestoda: Lecanicephalidea) and description of H. folifer n. sp. from the zonetail butterfly ray Gymnura zonura (Bleeker) (Rajiformes: Gymnuridae)

Hexacanalis Perrenoud, 1931 was erected for H. abruptus (Southwell, 1911) Perrenoud, 1931 based on the presence of six excretory vessels, a unique feature among the Lecanicephalidea. The genus has since been considered a junior synonym of Cephalobothrium Shipley & Hornell, 1906 or Lecanicephalum Linton, 1890, or as a genus inquirendum. Based on examination of the syntype series of H. abruptus, this species is redescribed and a lectotype designated. Examination of cestodes from the zonetail butterfly ray Gymnura zonura (Bleeker) from off Indonesian Borneo resulted in the discovery of a second species. Hexacanalis folifer n. sp. is unique among lecanicephalideans in its possession of an ovary that is U-shaped in cross-section and craspedote proglottids with prominent posterior dorso-ventral processes in the form of large lappets. The presence of six excretory vessels, confirmed in both species, supports the validity of Hexacanalis. An additional species, H. pteroplateae (Zaidi & Khan, 1976) n. comb., also from a butterfly ray, G. micrura (Bloch & Schneider) [as Pteroplatea micrura (Bloch & Schneider)], is transferred to this genus from Cephalobothrium Shipley & Hornell, 1906. A revised diagnosis of Hexacanalis is presented. Seven species of this genus remain species inquirendae. Hexacanalis appears to parasitise species of the Gymnuridae van Hasselt; however, specific identifications of the hosts are in need of re-evaluation. A summary of the cestode parasites of the Gymnuridae is presented.     

Oriental bamboo leafhoppers: A new genus and two new species of Mukariinae (Hemiptera: Cicadellidae) from Southwest China and notes on related group

A new genus, Tiaobeinia n. gen., and two new species, T. bisubula n. sp. and T. emeiensis n. sp., breeding on bamboo in Southwest China, are described and illustrated. Based on the nature of the face, the apical veins of forewing and hindwing, the hind femur macrosetal formula, the valve, the subgenital plate, and the style, this genus should belong to the subfamily Mukariinae. The related genus Ratfronta Chen & Li 1997, placed previously in subfamily Nirvaninae, is noted in the present paper. A new combination, F. grandis (Ishihara 1961) n. comb., transferred from the genus Mohunia Distant, is proposed. Keys to the species of the new genus Tiaobeinia and the genus Flatfronta are provided. The importance of those groups as pests on bamboo is briefly discussed.     

On the systematics of section Engleria (Leonova) Tzvel. of hydrophilic genus <Emphasis Type="Italic">Typha</Emphasis> L.

As a result of a comparative and morphological analysis of the collection material of the herbaria of the Botanical Institute at the Russian Academy of Sciences (St. Petersburg, LE) and the Institute of Botany at the National Academy of Sciences of Ukraine (Kiev, KW), as well as herbarium materials from Irkutsk (Popov IRK herbarium) and Tomsk (Krylov TK herbarium); our own collected materials; and an analysis of literature data on hydrophilic genus Typha L., taxa of the section of Engleria (Leonova) Tzvel T. laxmannii Lepech., T. laxmannii var. getica Morariu, T. taxmannii var. bungei Krasnova & Durnikin, T. laxmannii var. turczaninovii Krasnova & Durnikin, T. veresczaginii Kryl. & Schischk., T. zerovii Klok fil. & A. Krasnova, T. pontica Klok. Fil. & A. Krasnova, and T. przewalskii Skvortsov, the subsection Mandshuriae A. Krasnova is described.     

Bartoliella pritchardae n. g., n. sp. (Digenea: Opecoelidae) in Epinephelides armatus (Serranidae) from temperate marine waters of Western Australia

An opecoelid, Bartoliella pritchardae n. g., n. sp., is described from the intestine of Epinephelides armatus from Western Australia. The new genus has been assigned to the subfamily Opecoelininae Gibson & Bray, 1984, bringing the number of genera in the subfamily to two. Although the new genus is similar to Opecoelina Manter, 1934 morphologically, the pedunculate ventral sucker and complete absence of a cirrus-sac necessitate the erection of a new genus. A formal re-definition of the subfamily is given, based on the diagnoses of the genera Opecoelina and Bartoliella n. g.
