Abstract
Over 30 species of the genus Bireta (Schintlmeister, 2008) are known from the Palearctic and neighbouring regions of Southeast Asia. Individual species of this genus are externally similar, but can be separated by characters of the male genitalia. Bireta are mostly distributed throughout Southeast Asia, especially China (Kiriakoff, 1962; Kobayashi & Kishida, 2004; Kobayashi, Kishida & Min, 2008; Schintlmeister & Fang, 2001) and Thailand (Schintlmeister, 2007).
