摘要
云南鹤庆盆地晚第四纪 (1 50 0 0 0 - 1 2 0 0 0 a BP) HQ钻孔剖面建立介形类 2新属 6新种 ,即玻璃介科的 Candona parva sp.nov.,Yunnanicandona oblonga sp.nov.,Lineocyprisgranulosasp. nov.,L .gibba sp. nov.以及湖花介科的 Parachinocythere reticulata gen. et sp. nov.,H eterometacyprisheqingensisgen.etsp.nov.。参照剖面已有的环境信息 ,对新属种的生态特征进行了初步推测。
Two new genera and six new species are erected from late Quaternary deposits (150 000-12 000aBP) of Core HQ in Heqing Basin, Yunnan. Among them three genera and four species, namely Candona parva sp. nov., Yunnanicandona oblonga sp. nov., Lineocypris granulosa sp. nov., L.gibba sp. nov. are placed in family Candonidae and two genera and two species, namely Parachinocythere reticulata gen. et sp. nov., Heterometacypris heqingensis gen. et sp. nov. belong to family Limnocytheridae. Based on the palaeoenvironmental information of known genera and species, pollen and geochemical indexes in Core HQ, the ecological characteristics of the new genera and species are discussed.
