The Palearctic species of Braconidae with brachypterous, micropterous, or apterous modification are discussed. The following new species are described: Chremylus planispinus Belokobylskij (France, Algeria), Chremylus algecirasus Belokobylskij (Spain), Pambolus erogolus Belokobylskij (Mongolia), Pambolus ovchinnikovi Belokobylskij (Kyr- gyzstan), Hormius stauropolicus Belokobylskij (Russia (North Caucasus)), Bracon (Habrobracon) barbieri Belokobylskij (Algeria), and Panerema kamtshatica Belokobylskij (Russia (Kamchatka)). The following species are re- described: Heterospilus hemipterus (Thomson) (male and female), Chremylus pomonellae (Atanasov) (male, female and macropterous form), Hormius minialatus Tobias (female), and Aleiodes (Chelonorhogas) hemipterus Marshall (male and female). Lituania brachyptera Jakimavicius, 1968 is a new synonym of Eurybolus hemipterus Thomson, 1892. Chremylus pomonellae (Atanasov), new combination, is transferred from Rhyssalus. Aleiodes hemipterus is placed in the subgenus Chelonorhogas Enderlein. Asobara subalata (Zaykov & Fischer) is returned from Phaenocarpa Foerster. New distribu- tion records are reported for Ecphylus (Sactopus) caudatus Ruschka, H. hemipterus, Rhaconotus hispanicus Belokobyl- skij, Pambolus tricolor (Ruthe), Hormius minialatus Tobias, A. (C.) hemipterus, and Pseudopezomachus kasparyani Tobias. A key for identifying all Palearctic flightless cyclostome braconid species, and the genera in which they are placed, is provided. A discussion about the diversity, morphological characters, and natural history of wing size reduction, and possible reasons for flightlessness, is provided.
