Six new species of the genus Dicranosepsis Duda (Diptera, Sepsidae) from Vietnam, with a revised key to the species

The flies of the genus Dicranosepsis from Vietnam were investigated and classified taxonomically. Six new species (D. longa sp. nov., D. kurahashii sp. nov., D. monoseta sp. nov., D. sinuosa sp. nov., D. barbata sp. nov., and D. vietnamensis sp. nov.) are described and illustrated. Dicranosepsis is redefined and a revised key to the species is also provided.     

中国松塔牛肝菌属新种和新记录种

本文报道松塔牛肝菌属四个新种,即:裸皱松塔牛肝菌Strobilomyces gla-bellus Ying sp.nov.,阔裂松塔牛肝菌S.latirimosus Ying sp.nov.,微茸松塔牛肝菌S.subnudus Ying sp.nov.,短绒松塔牛肝菌S.velutinus Ying sp.nov.;及四个中国新记录种,即:柔鳞松塔牛肝菌S.mollis Corner,疣鳞松塔牛肝菌S.nigricans Berk.,锥鳞松塔牛肝菌S.polypyramis Hook.,半裸松塔牛肝菌S.semi-nudus Hongo.松塔牛肝菌属Strobilomyces以其具有变黑的担子果与菌幕、不粘的菌盖上有疣状、绵绒状或刺状鳞片以及黑褐色带明显纹饰的孢子而易于识别。Singer(1945)按孢子纹饰的不同将松塔牛肝菌属分为两个组,其一为具疣、刺和网纹的种类;另一为具纵贯孢子两端的翼状棱纹的种类。对于后者的归属问题,Pegler & Young持不同见解,并于1981建立了非洲牛肝菌属AfroboletusPegler & Young以纳孢子具翼状纵棱和孢缘边(rim)的种类;含2—4种,分布在非洲近赤道的地区。在中国,松塔牛肝菌属已报道过三个种,即:松塔牛肝菌Strobilomyces,floc-copus(Vahl.ex Fr.)Karst.光头松塔牛肝菌S.glabriceps Chiu和混淆松塔牛肝菌S.confusus Sing.。裘维蕃(1948,1957)曾描述过网孢松塔牛肝菌Strobi-lomyces retisporus(Pat.et Bak.)Gilb.但因其子实体色鲜红至褐红而不变黑色、子层体淡暗黄色且菌肉不变红-黑色、孢子具网纹而宜转隶于Heimiellia Boedijn(1951)。文中有新分类单位和国内已知种的分种检索表、新种的拉丁文和英文描述并有绘图和扫描电镜照片示明孢子纹饰。     

Nemerteans of the Great Barrier Reef 3. Anopla Heteronemertea (Lineidae)

Nine species of lineid heteronemerteans are recorded from the Great Barrier Reef province of Australia. Six of these are new species, including four new genera, and are fully described and illustrated. These are Aetheorhynchus actites gen. et sp. nov. , Bennettiainsularis gen. et sp. nov., Cerebratulus magnetkus sp. nov., Colemania albulus gen. et sp. nov., Mkrura tridacnae sp. nov. and Quasilineus pulcherrimus gen. ct sp. nov. Lineus tricuspidatus (Quoy & Gaimard) is re-established, illustrated and described. Gorgonorhynchus repens Dakin & Fordham and Parborlasia hutchingsi Gibson have been fully described elsewhere, but a full list of known locations is provided.     

Four new yeast species of the genus Sporobolomyces from plant leaves

Among the ballistoconidium-forming yeast strains isolated from various plant leaves collected in North and Northeast China, 12 strains forming orange to orange-red colored colonies were revealed to represent four novel species of the genus Sporobolomyces by conventional, chemotaxonomic and molecular phylogenetic studies, based on the 26S-rDNA D1/D2 domain and internal transcribed spacer (ITS) region sequences. Sporobolomyces beijingensis sp. nov., represented by eight strains (type strain CB 80T = AS 2.2365T = CBS 9730T), and Sporobolomyces jilinensis sp. nov., represented by two strains (type strain CB 118T = AS 2.2301T = CBS 9728T), clustered in the Johnsonii clade of the Sporidiobolus lineage. Sporobolomyces clavatus sp. nov., represented by strain CB 281T (= AS 2.2318T = CBS 9729T), belonged to the Agaricostilbum lineage and showed a close relationship to Sporobolomyces ruber and Sporobolomyces dracophylli. Sporobolomyces symmetricus sp. nov., represented by strain CB 64T(= AS 2.2299T = CBS 9727T), formed nearly symmetrical ballistoconidia and was closely related with Sporobolomyces vermiculatus and Sporobolomyces gracilis in the Gracilis clade of the Erythrobasidium lineage.     

The genus Phyllomyza Fallén (Diptera: Milichiidae) from Japan, with descriptions of four new species

The Japanese species of the genus Phyllomyza Fallén are revised. Four new species, Phyllomyza kanmiyai sp. nov., P. amamiensis sp. nov., P. proceripalpis sp. nov. and P. japonica sp. nov., are described and illustrated. P. securicornis Fallén is recorded from Japan for the first time. A key to the Japanese species of Phyllomyza is presented.     

子囊菌二新种

本文报道在我国东北地区发现寄生在落叶松(Larix Mill.)上的二个子囊菌新种——多孢小黑腐皮壳(Valsella multispora sp.nov.)及落叶松隐腐皮壳(Cryptovalsa laricina sp.nov.)。其形态特征有汉文和拉丁文描述以及显微照像图版。     

西藏阿蠓属两新种(双翅目:蠓科)

本文描述了发现于中国西藏的蠓科阿蠓属昆虫两新种 ,分别命名为钩茎阿蠓 (Alluadomyiarostrata)和双刺阿蠓 (A bispinula)。二新种模式标本保存于军事医学科学院医学昆虫标本馆。
