The First Record of the Family Chamaemyiidae (Diptera: Lauxanioidea) from Korea

The family Chamaemyiidae is commonly referred to as aphid flies, as all larvae are predators of sternorrhynchous aphidoid or coccoid hemiptera, as well as a small group of acalyptratae flies found worldwide. Adults are small flies and typically found near their larval prey in grasslands and forests. They have a silver-gray body with dark gray or black markings on the abdominal tergites. This family is described for the first time in the Korean fauna, based on the discovery of two nominated species: Leucopis argentata and Leucopis glyphinivora. Diagnoses and figures about the firstly recorded species, and a key to the Korean species are provided herein.
