The taxonomic status of two species of predaceous midges in the genera Bezzia and Palpomyia described by STÆGER (1839) in the genus Ceratopogon (Diptera: Ceratopogonidae: Palpomyiini)
Lectotypes are designated for the predaceous midges, Ceratopogon circumdatus Stæger, 1839, and Stæger, 1839 housed in the Copenhagen Zoological Museum, Denmark, and both species are redescribed and photographed. Ceratopogon circumdatus is removed from synonymy with Bezzia solstitialis (Winnertz, 1852) and recognized as a new synonym of Bezzia annulipes (Meigen, 1830). Ceratopogon binotatus Stæger, 1839, is removed from synonymy with Palpomyia lineata (Meigen, 1804) and recognized as the distinct species, Palpomyia binotata (Stæger, 1839)
