报道了在广西西南部发现的一个中国新记录属--高平蕨属Caobangia A.R.Smith & X.C.Zhang,该属隶属于水龙骨科Polypodiaceae瓦韦亚科Lepisorioideae,与瓦韦亚科中的骨牌蕨属Lepidogrammitis、瓦韦属Lepisorus和伏石蕨属Lemmaphyllum在形态上较相似,区别在于该属具有长的丝状横走茎,茎上的鳞片基部旱粗筛孔状,叶单一(不分裂),同型或近二型,密被针状鳞片,孢子囊群着生于中脉两边各一行,无隔丝.该属只含一种,即高平蕨Caobangia squamata A.R.Smith & X.C.Zhang,目前仅知分布于越南北部的高平省和中国广西的西南部.本文根据原始文献和广西的标本对该单型属的特征作了描述,并提供了高平蕨在广西的生态照片.  相似文献

A new genus and species, Palaeotanaos oisensis, is the first described representative of Apioninae from the Lower Eocene Oise amber. The new genus belongs to the tribe Tanaini and is similar to the genus Tanaos Schoenherr, 1826 and differs from it in the convex, not flattened, and slightly elongate body, the antennae inserted in basal one-third of rostrum, comparatively long flagellum, and elongate club, large and strongly convex eyes, narrow and long tibiae without mucro, short precoxal part of prothorax, and narrower and long tarsi.  相似文献

A freshwater dinoflagellate was identified as Durinskia baltica (Levander) Carty & Cox by morphological characteristics,with the plate formula:Po,x,4',2a,6',5c,4s,5',2'.Durinskia was a newly recorded dinoflagellate genus for China with two anterior intercalary plates and six characteristic precingular plates.Partial sequences of the small and large subunit ribosomal DNA and internal transcribed spacer sequences for the dinoflagellate cells were obtained from field samples.Molecular phylogenetic results indicated Durinskia species could cluster into a monophyletic group,which were distinct from Peridinium species.According to morphological and molecular evidence,it was agreed that the genus Durinskia was separated from the genus Peridinium,which could be a polyphyletic group.In addition,D.baltica was an infrequent diatom-harboring dinoflagellate which was known to possess an endosymbiotic diatom or diatom-like alga.The phylogenetic analyses indicated that D.baltica had a close affinity with Peridiniopsis penardii and P.niei,common freshwater bloom-forming species in China.  相似文献

A second species of the enigmatic lampyrid genus Oculogryphus is described and figured as Oculogryphus bicolorsp. n. from Vietnam. The definition of the genus is slightly modified with consideration of newly detected morphological variation from this species. According to a comprehensive phylogenetic analysis including nearly 80% of documented lampyrid genera, Oculogryphus is the putative sister group to Stenocladius s. str. within the paraphyletic group of Ototretinae-Ototretadrilinae.The classification of Stenocladius is briefly discussed in this context.  相似文献

Harpapion safranum sp. n. and Harpapion borisi sp. n. are described and figured. Harpapion vietnamense (Korotyaev, 1987) is recorded as new for China. The genitalia andterminalia of H. considerandum, H. coelebs andH. vietnamense are redescribed and redrawn. The diagnostic characters of Harpapion are defined. A key to the known species of the genus Harpapion from China is provided. Affinities with the genus Flavopodapion Korotyaev, 1987 are discussed.  相似文献
