Abstract
New species of Tanyderidae are described from the Jurassic beds of Asia (Kubekovo, Karatau and Shar Teg localities), viz. Praemacrochile ansorgei n. sp., Praemacrochile kaluginae n. sp., Protanyderus invalidus n. sp., Protanyderus savtchenkoi n. sp. and Protanyderus nebulosus n.sp. Mesozoic species of Praemacrochile and Protanyderus are keyed and illustrated. Fossil tanyderid larvae tentatively attributed to ?Protanyderus sp. are described for the first time.
