Contributions to the rotifer Fauna of West Bengal. Part I. Family Lecanidae

In the present study thirty six lecanid rotifers, spreading over thirty species, have been recorded and illustrated. A new combination i.e., Lecane luna f. dorsicalis has been proposed. The validity of the number of toes as character of generic importance has been examined.     

On Lecane tanganyikae new species (Rotifera: Monogononta, Lecanidae)

A new species of rotifer, Lecane tanganyikae n.sp., is described from the littoral of Lake Tanganyika and some water bodies in the plain of the Rusizi river near Lake Tanganyika, Bujumbura Province, Burundi. The affiliation of the new species, especially in relation to L. elsa Hauer, is discussed.     

Lecane donyanaensis n. sp. (Rotifera: Monogononta,Lecanidae) from the Doñana National Park (Spain)

A hitherto unknown rotifer species was found in ponds of Doñana National Park (Spain) during winter 1990, 1991 and 1992. It belongs to the family Lecanidae (Monogononta), is related to Lecane ungulata and superficially resembles Lecane leontina.Two specimens of this species hatched after two days incubation of pond sediments in the laboratory.     

Rotifers from Andhra Pradesh,India — III., family Lecanidae including two new species

Seventeen species of rotifers of the family Lecanidae, including two new species: Lecane donnerianus sp.nov. and L. bidentata sp.nov., have been described.     

Lecane segersi n.sp. (Rotifera, Lecanidae) from Thailand

Lecane segersi n.sp. collected from a swamp in Udornthani province, northeastern part of Thailand, is described and figured. It is closely related to the common, warm-stenotherm Lecane papuana (Murray), but distinguished by the presence of inwardly directed antero-lateral spines.     

The rotifer fauna of Lake Kud-Thing,a shallow lake in Nong Khai Province,northeast Thailand

The species composition of the rotifer fauna of Lake Kud-Thing, Nong Khai Province, northeast Thailand was investigated in a monthly sampling program from January to December 1998. A remarkably rich rotifer community consisting of 183 taxa was recorded, including 32 new records to the Thai fauna. The most diverse genera were Lecane (23.5%), followed by Trichocerca (16.9%) and Lepadella (11.5%). Lecane isanensis n. sp. is described and figured. Thirteen species (Aspelta circinator, Collotheca tenuilobata, Lecane nelsoni, Lepadella benjamini, Lepadella eurysterna, Sinantherina ariprepes, Testudinella cf. insinuata, Trichocerca abilioi, Trichocerca inermis, Trichocerca montana, Trichocerca orca, Trichocerca rosea and Trichocerca simonei) are new to the Oriental region. Notably, the record of Trichocerca orca is the first since its discovery in New Zealand in 1913. The rotifers can be classified into three groups based on duration of appearance; (1) common, perennial; (2) uncommon, perennial; and (3) uncommon, sporadic species. The high species richness of rotifers, particularly members of the genera Lecane and Trichocerca, but low diversity of Brachionus together suggest that the lake is probably not eutrophicated.     

A new Lecanid rotifer from India

During the course of an extensive survey of the ecology and systematics of the rotifers from Andhra Pradesh, India, a new species of the genus Lecane has been encountered and described as Lecane eswari sp. nov. It has been found that this species occurs in the winter season and is totally absent in the summer months.

河北小五台山叶生丝孢菌

小五台山自然保护区位于河北省西部,为河北省第一高峰。变化悬殊的地形,使其由低谷到亚高山草甸呈明显独特的垂直植被类型分布带,山势陡峻,谷路隘险,具有华北地区罕见的森林植被及丰富的植物资源。狭谷陡峰,葳蒐险奇的地形地貌,又形成了多变的气候特征,因此蕴藏着相当丰富的真菌资源。作者1990年8月在该地区考察期间,共采集涉及林木、农作物、花卉、蔬菜等植物病害标本240份。本文报道小五台山的丝孢菌(Hyphomycetes)14属40种,其中有二个新种:(木来)木菌绒孢(Mycovellosiella coni Y.L.Guo, sp. nov.),五味子色链隔孢(Phaeoramularia schisandrae Y.L.

Guo, sp. nov.)生于五味子科(Schisandraceae)五味子[Schisandra chinensis (Tunz.) Baill.]叶上,子实体生于叶背面。菌丝体内生。具子座。分生孢子梗紧密簇生,浅青黄褐色,不分枝,曲膝状,1-5个隔膜,20.0-75.0 (-95.0) × 4.0-5.0 μm。分生孢子圆柱形,近无色,链生并具枝链,1-4个隔膜,15.0-40.0 × 3.0-4.0 μm。五味子科既无尾孢菌属也无色链隔孢属的报道。文中为新种提供了拉丁文简介、描述和图,新记录种进行了简要描述。研究的标本保藏在中国科学院微生物研究所真菌标本室(HMAS)。
