Notes

Of the original type material, 18 specimens were found that resemble the original description and illustrations provided for A. flavipes . One labeled female in good condition, here considered to be the holotype, has two labels: “Shangrao, Jiangxi Prov., host: egg of Dendrolimus kikuchii (Drury) ”, and “ 15–25 June 1984, YU Jingting”. One labeled male in good condition, here considered to be the allotype, has two labels the same as the holotype. Other specimens considered as paratypes: 6 ♀♀, 4 ♂♂, Dexing (part of Shangrao City) or Shangrao, Jiangxi Prov., 15–25 June 1984, YU Jingting; 1 ♂, Yushan, Jiangxi Prov., 17 Nov. 1984, YU Jingting; 1 ♀, Liantang, Jiangxi Prov., early August 1955; 4 ♀♀, Xintai, Shandong Prov., July – August 1987, FAN Di. All the specimens from Heilongjiang Province were destroyed. The label dates of the 12 specimens from Dexing and Shangrao labeled by Sheng are in conflict with the published data. We suspect that 15 June is abbreviated for 15–25 June.

Remarks

Females of A. flavipes resemble those of A. fulloi , but the body is yellowish-brown ( Fig. 9 ) rather than metallic green ( Fig. 24 ); scrobal depression with lateral margin not distinct dorsally, but about 1.5–2.0 × diameter of ocellus from anterior ocellus ( Fig. 12 ) rather than 0.8–1.10 × diameter of ocellus from anterior ocellus ( Fig. 20 ); and fore wing with basal infuscate setose region about 2.2 × wider than hyaline cross-band ( Fig. 10 ) rather than 3 × wider than hyaline cross-band behind MV ( Fig. 23 ). Males differ from those of A. fulloi by the antennal clava being as long as the apical three funiculars, much shorter than the apical four funiculars ( Figs 15, 18 ). In the key of Kalina (1981), females of A. flavipes key out to A. formosanus , but in A. formosanus the lateral margins of the scrobal depression reach the anterior ocellus, the frontovertex is as wide as an eye, and the anterior convex part of the medial lobe is 0.78 × the total length of the mesoscutum.
