本文重点记述抚顺煤田始新世琥珀中蜉蝣目一个新属——喜沼小蜉属(Philolimnias gen. nov.).这个属在分类上属于小蜉科(Ephemerellidae),与近代生存的小蜉属布形式,前缘区极窄,触角细长,尤其是抱握器更为特殊,为抚顺煤田独特性质的新种群,至今尚未发现,从分类观点,应当建立新属,喜沼小蜉属的建立将为始新世地层划分和对比提供化石依据。本文还讨论了几年来的抚顺煤田地层层序和时代的新成果(详细内容另文发表),这些成果已在抚顺煤矿中应用,并对于邻区的生产工作和地层对比也有一定的实际价值。

本文记述了三尾类蜉蝣Ephemeropsis trisetalis稚虫的脉相和翅关节区特征为化石昆虫保存史上罕见材料,脉相中显出颇大的径脉区和前缘区十分相似于某些原始的古生代蜉蝣,或许可以提示发达的径脉区和前缘脉区是蜉蝣翅进化史中的初期特征.再者,现代蜉蝣的翅关节区退化,一般由一组不发达,分化很弱的骨板和肩板组成;这个化石种的翅关节区具发达的骨板和肩板似指示现化蜉蝣翅关节区退化是后生获得的性状.

柔裳蜉属在我国仅记载有吉氏柔裳蜉(Habrophlebiodes gillies Peters 1963)一种。本文根据采自南京的柔裳蜉属中鉴定一新种:紫金柔裳蜉(Habrophlebiodes zijinensis sp. nov. ),并对其成虫、稚虫的形态特征作了详细的描述。新种与吉氏柔裳蜉相似。但紫金柔裳蜉身体较宽;体色较淡,头、胸部呈灰棕色,腹部淡灰棕色;外生殖器阳茎叶基部愈合,仅近端部1/3处凹陷,顶端腹侧有一钩状弯曲。两者有明显区别。

详细描述了采自安徽黄土坑的一新种：黑翅蜉（***）的形态特征，并对前人划分蜉蝣属各亚属的标准作了修订。认为将前翅MP2脉与CuA脉在基部连接与否作为划分蜉蝣亚属的标准比较可行。这样，黑翅蜉应归入到蜉蝣属叉蜉亚属（Dicrephemera）。黑翅蜉区别于蜉蝣属其它种的特征为：1）雄成虫前翅外侧大部分呈棕红色，半透明，雌成虫的前翅只具少许斑点，翅透明；2）后翅外侧缘具棕红色斑纹，半透明，而雌成虫后翅不具斑纹，透明，3）雄、雌成虫腹部背板上的斑纹形式及排列；4）雄成虫的尾铗大部分为黑色；5）雄成虫的阳茎的形状独特，且两阳茎紧靠。

A field study was performed at rivers in Gunung Jerai forest reserve(Kedah,Malaysia) to assess seasonal changes in mayfly community structure and abundance in relation to altitude and water *** at lower(Batu Hampar River) and higher(Teroi River) elevations were visited through dry and wet seasons in September 2007 to August *** visits were made to 20 sites on each river,and water and aquatic insects were sampled using D-pond aquatic *** was warmer,more acid,and more turbid in Teroi River during wet *** was the only nutrient exhibiting significant seasonal variations(greater during wet season).Chemical oxygen demand content was higher in Teroi River where biochemical oxygen demand content was low during wet *** richness was higher in Batu Hampar River,but displayed seasonal variations only in Teroi *** the eight families encountered,Baetidae was the *** abundance was usually high during wet season,and those belonging to the dominant genus(Baetis) were more abundant in Teroi *** was the second commonest family;its predominant genus,Thalerospyrus was more abundant in Teroi River during dry ***,Leptophlebiidae and Oligoneuriidae were only found in Batu Hampar River where their abundances peaked during dry season,i.e.,Habrophlebiodes *** Isonychia *** and Teloganodidae occurred only in Teroi River,with the first found only during dry *** were recorded under very distinct physicochemical conditions,illustrating their potential usefulness for assessing water ***,leptophlebids,oligoneurids ephemerellids and teloganodids seem to be particularly sensitive to temperature,acidity,turbidity,chemical oxygen demand and biochemical oxygen demand,parameters that varied with river altitude.
