抚顺煤田始新世琥珀中喜沼小蜉属(新属)——Philolimnias gen. nov. (Ephemeroptera,Insecta)的研究

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。

DISCOVERY OF NEW FOSSIL SPIDERS IN AMBER OF FUSHUN COALFIELD

A new genus, Sinodictyna (Archanda), has been obtained from amber on the main coalbeds of the Gucheggzi Formation (E_(2g)~1), Fush?n Coalfield In Liaoning Province. It suggeststhat Sinodictyna belongs to a regional form in China and that it differs from European Balticamber Eolathys in the chelate teeth, pedipal, walking legs and its appendages. New genusdiscovered first in China fills in tlie gaps in the field of paleontology of China.
