长角冬夜蛾属Meganyctycia Hreblay & Ronkay,1998是由Márton Hreblay和László Ronkay在1998年以长角冬夜蛾Meganyctycia forcipata Hreblay & Ronkay,1998为模式种建立,并第一次记录在Moths of Nepal(Haruta,1998)中,目前共包含6个种:M. forcipata Hreblay & Ronkay,1998M. armata Hreblay & Ronkay,1998M. fansipana Hreblay,Peregovits & Ronkay,1999M. brevicorna Hreblay & Ronkay,1999M. hanhuilini Ronkay,Ronkay,Gyulai & Hacker,2010M. salaka Hreblay & Ronkay,1999(Haruta,1998;Hrebly et al., 1999Hreblay & Ronkay,1999Ronkay et al., 2010)。元夜蛾属Avitta Walker, 1858共6种(Haruta,1993;Kononenko & Pinratana,2005Park & Bae,2007),其中中国记载3种(陈一心,1999),现增加1新记录种褐元夜蛾Avitta rufifrons Moore,[1887]。本文对中国新记录属属征、新记录种成虫外部形态和外生殖器结构进行了描述,并给出其高清晰图片和国内外分布信息。研究标本保存于西藏农牧学院高原生态研究所。
