Rediscovery of Paramecium duboscqui Chatton & Brachon, 1933, and a Description of Its Characteristics

ABSTRACT. Paramecium duboscqui Chatton & Brachon, 1933, was rediscovered in Harbin, China, in 1974. In addition to the morphological features described by Chatton and Brachon, more details such as the silver-line system, buccal apparatus, stomatogenetic pater, mating types and temperature adaptation are described here. Although minor differences exist between the strains from France and China, the evidence indicates that they are really the same species and a member of the "bursaria" group.     

Pohlia muyldermansii Wilcz. & Dem. var. pseudomuyldermansii var. nov., a new name for P. muyldermansii Wilcz. & Dem. sensu Lewis & Smith

Abstract

The results of a comparative study of Pohlia muyldermansii from Continental Europe and the British Isles are presented. Two varieties are recognized, var. muyldermansii from Belgium and the Netherlands and var. pseudomuyldermansii var. nov. from Great Britain, Ireland, Austria and Switzerland. P. camptotrachela is reported from Belgium and differences between this species and P. muyldermansii discussed.     

Lobosporangium, a new name for Echinosporangium Malloch, and Gamsiella, a new genus for Mortierella multidivaricata

Lobosporangium is proposed as a new name for Echinosporangium Malloch, a later homonym of Echinosporangium Kylin. Lobosporangium transversale was isolated from arid soils on three occasions between 1964 and 1968 but has not been reported again. Observations on sporangium development in culture revealed rapid sporangiospore germination, rapidly growing hyphae forming anastomoses, threefold dichotomously branching aerial sporangiophores and formation of clusters of eight sporangia. The sporangia of L. transversale are illustrated, and the placement of Lobosporangium in the Mortierellaceae is discussed. A new genus, Gamsiella, is proposed that is based on Mortierella multidivaricata. Sporangial ontogeny of Gamsiella is compared with that presented here for Lobosporangium.     

A new sharpshooter genus for Sphinctogonia lingula Yang & Li (Hemiptera,Cicadellidae, Cicadellini) from China

A new genus, Sphinctogoniella, is described to accommodate Sphinctogonia lingula Yang & Li, 2002, its type species from China. Sphinctogoniella lingula (Yang & Li, 2002), comb. n. is re-described and illustrated. Differences between the new genus and Sphinctogonia Breddin, 1901 are tabulated.     

Tanochenia nov. gen., a new generic name for the radiolarian species Stylotrochus asteros Tan & Chen, 1999

The structural study of several Quaternary specimens of the radiolarian species Stylotrochus asteros Tan and Chen, 1999 proves that this species does not belong to this genus or to other Cenozoic genera so far known. This species has a large lenticular lattice cortical shell with one face convex and the other one concave or flat, and an initial skeleton inside it consisting of a small tumour-shaped spongy structure attached to the convex side. Given these peculiarities of this species, the author erects for it the genus Tanochenia nov. gen.     

Navia, a replacement generic name for Euterpia Navia & Flechtmann (Prostigmata: Eriophyoidea: Eriophyidae)

Navia nom. nov. is proposed for Euterpia Navia & Flechtmann, 2005 (Prostigmata: Eriophyoidea), preoccupied by Euterpia Bondar, 1942 (Insecta: Coleoptera: Curculionidae).     

Stirtonanthus, a new name for Stirtonia (Leguminosae, tribe Podalyrieae)

The new generic name Stirtonanthus is proposed to replace the illegitimate Stirtonia Van Wyk & Schutte (1994), which proves to be a later homonym of Stirtonia A. L . Smith (1926) and Stirtonia R. Brown (1900).     

Ighermia, a new genus of the Asteraceae – Inuleae

An aberrant species of the genus Asteriscus (Asteraceae–Inuleae), A. pinifolius from SW Morocco, is here proposed to be removed and placed in a separate, monotypic genus Ighermia. The systematic position and morphology of the new genus are also discussed.     

纤细滇美龙(Dianmeisaurus gracilis Shang & Li,2015)新材料

根据一件产自云南罗平中三叠世关岭组Ⅱ段的新标本并结合产自相同地点和地层中的模式标本对纤细滇美龙(Dianmeisaurus gracilis Shang & Li,2015)进行了详细研究.原模式标本暴露其腹而,而新标本暴露其背面,两者互相补充提供了更完整、精确的纤细滇美龙解剖学信息.新材料揭示该种具有非常短小的吻部,眶前区的长度不仅短于眶后区长度,甚至短于眼眶的长度;外鼻孔小且位置靠前,即鼻孔前区的长度短于鼻孔后缘与眼眶前缘之间的距离;由两额骨构成的眼眶间隔非常狭窄,宽度小于顶骨平台宽度的1/3;额骨前后两端均具渐尖的突起;顶骨后部不收缩,顶骨平台后缘呈深V型.补充了新信息和包含更多属种(如Dawazisaurus)后的系统发育学分析支持了之前滇美龙和滇东龙互为姊妹群的结论,同时它们和马家山龙、滇肿龙、贵州龙和大洼子龙一起构成了一个仅由中国的属种组成的单系类群.与欧洲肿肋龙类群(Dactylosaurus,Anarosaurus,Serpianosaurus和Neusticosaurus)相比,这一单系类群与幻龙类有更近的亲缘关系.
