Pyralinae are one of the largest subfamilies belonging to Pyralidae, which comprises about 900 species of 217 genera in the world, and 150 species belonging to 32 genera are recorded in China (Li houhun, 2009). This subfamily are characterized by the following characteristics: head rounded, chaetosemata present, proboscis developed. Labial palpus porrect or upturned. Maxillary palpus small.

Liaoning Province is located in the southern part of NE China, the area of Liaoning is 146,900 km² and it is bounded on the south by the Yellow sea, on the southeast by North Korea, on the north by Jilin Province, and on the west by Inner Mongolia and Hebei Province. The mean annual temperature is 7-11℃, the mean annual precipitation is 600-1100 mm in northeast part, but 400 mm in west part. Liaoning Province is an important area for forest and agriculture, accordingly, to survey the diversity of Pyralinae is of great significance for systematic study in Liaoning Province. In this study, our materials examined come from the collection of Northeast forestry University from 2006-2010, and the collection of Incheon University from 2010-2012. Finally, we identified 11 species belonging to 8 genera, of them, 1 species are the first time reported in China, and 6 speices are the first time reported in Liaoning Province.
