摘要

Microterys vladimiri sp, n differs from M. hesperidum Trjapitzin et Khlopunov in the shape of the mandibles, longer marginal vein of the fore wing, shape of the hind margin of the propodeum and base of the metasoma which are not closely fitting, and also in the longer ovipositor. M. lilyae sp n. differs from M. speciosus Ishii in the shorter 1st segment of the antennal funicle and the oval metasoma, and from M. nietneri Motschulsky (= flavus Howard), in the shape of the metasoma and in the shorter ovipositor, which projects for 1/5 length of the metasoma. Anicetus mysterius sp. n. differs from A. ceroplasis Ishii in that the upper margin of 4-6th funicular segments combined is more than twice as long as that of lst-3rd segments. The scutellum bearsonly 32-34 setae A. thanhi sp. n. is similar to the preceding species, but differs in the wide frontovertex, shape of sensilla at the apical margin of 3rd segment of the club (see Figs. 15 and 22), and shape of the metasoma. A. korotyaevi sp. n. is similar to A, ohgushii Tachikawa, but differs in the short upper margin of 5th funicular segment, which is as long as 4th segment, and in the unusually small number of setae on the scutellum (12 ) Metaphycus halongiensis sp. n. differs from the similar M. dispar Mercet in the presence of a wide dark median stripe on the mesoscutum and scutellum and in the alveolate sculpture of the mesoscutum, scutellum, and tergites: the alveoli are covered with fine punctures and wrinkles forming an intricate pattern M. monastyrskii Sugonyaev has a similar type of the sculpture but differs in the 3-segmented maxillary and labial palpi. Prochiloneurus rumaki sp. n. differs from the similar P. nagasakiensis Ishii in the absence of a tuft of long setae at the apex of the scutellum and in the uniform weak in-fuscation of the fore wings, except in their basal quarter.
