Coniopteryginae is a highly diversified group of Coniopterygidae. In Korea, only two species, Semidalis aleyrodiformis and Conwentzia pineticola, are recorded. Here we report two additional species of Coniopteryginae, Coniopteryx pallescens and Conwentzia sinica, as new records in Korea. Brief descriptions, photos of adults and male genitalia as well as COI barcode sequences are provided.

Conwentzia와 C. pineticola를 한국 미기록속 및 미기록종으로 보고한다. 본 종의 성충에 대한 간략한 기재와 성충 사진 및 생식기 사진과 함께, 16S rRNA 와 COI 염기서열을 제공한다.

Even with the tiny body size, 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 and they are fairly well-known natural predators of small insects such as scale insects, aphids, and mites. Genus Cowentzia is one of the characteristic groups of Coniopteryginae; they have conspicuously reduced hind wings than other groups have. The genus contain about 14 species in the world. Here we present Conwentzia, a new genus record, with Conwentzia pineticola in Korea. We provide a brief description, photos of adult and male genitalia, and 16S rRNA sequence based the specimen examined.

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.

The family Coniopterygidae belonging to Neuroptera with Semidalis aleyrodiformis (Stephens) is introduced from the Korean Peninsula in the present study. Taxonomic descriptions of the family and the species and illustrations of its wing and male genitalia are presented.

A recent study on Neuroptera brought us an attention to a newly found group, Coniopterygidae, dustywings. As we reported for the first time this year, this family has not been taxonomically reported in South Korea while it has been reported in North Korea before. In fact, this is known to be found in Japan and China, which means this probably have been around us for a long time. However, we found there was one species of which the name was once mentioned in a paper in 1978. It was reported by Kim, H.S. et al. in 1978 in a study of citrus red mite and its natural enemies (Kim et al., 1978). Although the spelling of the species was wrong even as a synonym, the species was found to be a natural enemy of citrus red mite, Panonychus citri in Jeju-do. We here report this taxonomically undescribed species for the first time in South Korea. The species is superficially similar to white flies but, unlike white flies, it is on our side as a natural enemy.
