XXXII. 1. 1979 p. 189-202 Aphidiidae (Hymenoptera) from Mongolia By H. TAKADA (Received 27 Januar, 1979) Abstract: Twenty-one species of Aphidiidae are recorded from Mongolia. Three new species: Adialytus kaszabi, Trioxys pappi and Binodoxys mongolicus are described. Information on the distribution of aphidiid parasites of aphid^ in Mongolia is very scant. The following records are based on a collection of Aphidiidae brought from Mongolia by Dr. Z. KASZAB of the Hungarian Natural History Museum, in 1964-6P. The material contains representatives of 21 species belonging to 8 genera; of them 3 species: Adialytus kaszabi, Trioxys pappi and Binodoxys mongolicus are new to science. The type specimens of the new species are deposited in the Hungarian Natural History Museum, Budapest. Ephedrus brevis Stelfox Ephedrus brevis Stelfox, 1941, Proc. R. Irish Acad. (B), 46:140-142.

Daisetsu, 11. VII. 1970, Z. Yamashita leg. ) except having the 1st flagellar segment of the antenna relatively longer and the petiole (fig. 2) a little narrower: in the present form the 1st flagellar segment is 5 times as long as broad at base and the petiole distinctly longer than the breadth at spiracle (9:7), while in the Japanese form the flagellar segment is 4 times as long as broad and the petiole as long as broad.
