本文对劳蛉亚属的分类作了研究和讨论。指出阳茎为本亚属雄蛉鉴别的最主要依据。雌蛉的分类鉴定宜把咽甲和受精囊两者形态结合起来观察。比较观察了本亚属G种白蛉的实物标本,将硕大白蛉吴氏亚种P.major wui(Yang et Xiong,1965)提升为吴氏白蛉P.(Lar.)wuiet(Yang Xiong,1965)stat.nov. This article has studied and discussed the classification of subgenus L. Pointed out that the main stem of male subgenus identification of the most important basis. Classification and identification of female should be combined pharynx and the morphology of both observed. The species specimens of G species in this subgenus were comparatively observed, and P. major wui (Yang et al., 1965) was upgraded to Larix wuiet (Yang Xiong, 1965) stat.nov.
