中国新记录的隐粉蛉属及一新种记述(脉翅目:粉蛉科)

THE GENUS CRYPTO SCENEA NEW TO CHINA, AND A SPECIES NEW TO SCIENCE (NEUROPTERA: CONIOPTERYGIDAE)

隐粉蛉属Cryptoscenea在囊粉蛉亚科(Aleuropteryginae)中是比较特殊的,其前翅中脉上缺少一般均具有的2个脉鬃。Enderlein 1914年以其1906年所描述的Helicoconis australiensis作为模式种建立了此属,至今只记载有5个种,除1种在新几内亚外,其余均分布在澳洲,本文系此属在我国的首次纪录,并增加1新种。所有模式标本均保存在北京农业大学昆虫标本室。
