Abstract: 记述了实小卷蛾属(小卷蛾亚科,花小卷蛾族)的一个新种,黄杉实小卷蛾Retinia pseudotsugaicola Liu et Wu, sp. nov..其幼虫危害黄杉Pseudotsuga sinensis Dode的球果,在云南省禄劝县云龙乡球果受害率达80%~90%.该新种雄性外生殖器的抱器瓣在腹面中央凹陷很深,抱器腹拐角几乎呈直角,抱器端的腹角尖,可与该属其它种相区别.该新种的雌性外生殖器与松实小卷蛾R.cristata很相似,但成虫的花纹完全不同,该新种前翅的中横带很宽,且布满了灰绿色和灰黄色的云状纹,而松实小卷蛾前翅的中横带则较窄,翅端有明显的肛上纹.在昆明禄劝县一年发生1代,以蛹在球果中越冬.越冬蛹于翌年3月下旬开始羽化.4月上旬至7月下旬是幼虫危害期.老熟幼虫7月下旬开始陆续化蛹越冬.提供了成虫外形、翅脉、雌雄外生殖器解剖图及幼虫的毛序图.模式标本保存在中国科学院动物研究所.
