Systematic Studies of Aphelinidae Ⅲ. The Species of Archenomus Howard from China (Hymenoptera,Aphelinidae)

The present paper deals with 13 species of the aphelinid genus Archenomus Howard from China, in which 2 species are new to China (marked with * ) and 4 species are described as new to science. A key to the females of species from China is provided. All the type specimens are housed in Biological Control Research Institute and Department of Plant Protection, Fujian Agricultural College. Genus Archenomus Howard 1 Archenomus sparsiciliatus Huang 2 Archenomus xanthothoracalis Huang 3 Archenomus orientalis Silvestri~* 4 Archenomus longiclava (Girault) 5 Archenomus bicolor Howard 6 Archenomus sunae Huang 7 Archenomus lauri Mercet 8 Archenomus calvus Viggiani et Ren 9 Archenomus processus Huang 10 Archenomus nudicellus Huang, sp. nov. (Fig. 1) It is similar to A. processus in the incolus group, but differs from the latter in mid lobe of mesoscutum with 9—11 setae, propodeum short and non—salient, and fore wing with a small speculum below marginal vein. Male unknown. Holotype♀, Wuyi Mountain, Fujian, 1987-06; Paratypes, 1 ♀, Wuyi Mountain, Fujian, 1985-08-02; 1♀, Wuyi Mountain, Fujian, 1988-09-06. Host unknown. 11 Archenomus coni funiculatus Huang, sp. nov. (Fig. 2) It is a member of the incolus group, but differs from the known species of the group in the basal two funicular segments combined together by a clear suture, the first funicle shortest, club acute from base to apex, and the apical segment of club acuminate and conical. Male is similar to the female but differs in the structure of antenna and the scape with a tubercle on the apical ventrad. Holotype♀, Allotype♂, Fuzhou, Fujian, 1987; Paratypes, 18♀♀, 14♀♀; same data as holotype; 2♀♀, Wuyi Mountain, Fujian, 1987-06; 6♀♀,4♀♀, Fuzhou, Fujian, 1988-09; 1♀, Wuyi Mountain, Fujian, 1989-07-20; 3? ￡, Wuyi Mountain, Fujian, 1989-08,-11. Host unknown. 12 Archenomus leptocerus Huang, sp. nov. (Fig. 3) It resembles A. incolus in the incolus group, but differs from the latter mainly in the different dimensions of antennal segments, and mid lobe of mesoscutum with 8 setae. Male unknown. Holotype♀, Fuzhou, Fujian, 1989-07-20; Paratypes, 1♀, Wuyi Mountain, Fujian, 1980-10-12; 3♀♀, Wuyi Mountain, Fujian, 1987-06; 2♀♀, Fuzhou, Fujian, 1987. Host unknown. 13 Archenomus stenopterus Huang, sp. nov. (Fig. 4) It resembles A. albi femur in the peratus group, from which it can be separated by fore wing narrower, marginal fringe longer, different proportion of length of antennal segment, and flagellum with a short sensillum respectively on the dorsocaudal margin of each segment, except on the dorsocentral margin of the apical segment of club. Male unknown. Holotype♀, Wuyi Mountain, Fujian, 1989-07-20. Host unknown.
