03DB87BDAA6E3E5AFCD0F8D2FC12F89A.taxon	discussion	Remarks. Gorham (1892) described Epilachna insignis based on the collection on Mr. Pratt in China (Kiu-kiang) as a new species. Pang et al. (2012) reported 20 species of Chinese Epilachna Chevrolat including E. insignis, with digital illustrations of the habitus, male and female genitalia. However, no description or other morphological illustrations were provided. According to Tomaszewska and Szawaryn (2016), some parts of genus Epilachna, including E. insignis, have been transferred to the genus Diekeana based on morphological and molecular characters. We collected four adult male specimens from southern part of south Korea and provide a detailed diagnosis for the first time herein. The species of Diekeana insignis can be distinguished by the following morphological characters: pronotum with transverse black marking in middle part, elytra strongly convex with densely pubescence, each elytron with seven large black markings, penis long, slightly bent at apical part, truncate at apex, parameres narrow and as long as penis guide in lateral view, penis guide narrow and pointed at apex.	en	Jung, Sang Woo, Kim, Chan Shin and Yoon-Ho (2023): New report of Diekeana insignis (Gorham, 1892) (Coleoptera: Coccinellidae: Epilachnini) in South Korea.
