Netelia Gray (1860) is the largest genus of the subfamily Try- Specimens used in this study were collected by light trapping phoninae, with species distributed worldwide, and all of the and Malaise trapping, and are deposited in the Animal Systematic members are koinobiont ectoparasitoids of lepidopteran larvae. So Laboratory of Yeungnam University, Gyeongsan, South Korea (YNU) far, more than 330 species have been described and divided into 12 and Laboratory of Insect Systematics, National Institute for Agro- subgenera (Bennett 2015). Among them, Amebachia Uchida (1928) Environmental Sciences, Tsukuba, Japan (NIAES). Morphological is described based on Amebachia baibarana from Taiwan and terminology mostly follows that of Gauld (1991), and terminology recognized since Townes (1969).
