Coniopterygidae is the fourth largest group of Neuroptera. There are currently 23 genera and 560 species recorded in the world. They have a tiny-sized body, and their wings are covered with whitish wax powder. In Korea, only one species, Semidalis aleyrodiformis has been recorded in Coniopteryginae. Recently we collected two additional species, each belonging to Spiloconis and Coniocompsa in Aleuropteryginae. In this poster, Spiloconis sexguttata and Coniocompsa postmaculata are newly recorded in Korea. Morphologically Spiloconis sexguttata has reddish colored body with some flagella segments black while Coniocompsa postmaculata has blackish pattern on forewing. We provide brief descriptions, photos of adults and male genitalia and DNA barcode sequences based the specimens examined.
