Diagnosis

Member of the indochinense species group. The original description of A. bimaculatum and the redescription by Hayat & Anis (1999) are adequate for its recognition.

This species is characterized by a more or less uniform brown body color; a short female antenna (F1 slightly shorter than pedicel) with a large clava, which is longer than combined length of 3 preceding segments ( Fig. 29 View FIGURES 29–31 ); an entire pronotum, with 2 pairs of dorsal and 3 pairs of lateral strong, blunt setae; a long, blunt axillar seta; absence of the frenal row of foveae on the scutellum (the frenal line is present); short "V"- shaped carinae on the propodeum ( Fig. 30 View FIGURES 29–31 ); a characteristic female forewing ( Fig. 31 View FIGURES 29–31 ) with two dark spots on the disc and usually two dorsal setae on the marginal vein; and the ovipositor which is not exserted beyond gastral apex but occupies almost the entire length of gaster (ovipositor length: metatibia length 1.1–1.2:1). In the Taiwanese specimens, the female has two dorsal macrochaetae on the forewing whereas the male (forewing hyaline, genitalia as in A. indochinense ) has only one. Acmopolynema bimaculatum is very close to A. indochinense , from which it differs mainly in the antennal and ovipositor features of the female (the funicle segments are relatively longer and ovipositor length: metatibia length is 1.7–1.9: 1 in A. indochinense ) as well as in the shape of the apical dark spot on the forewing, which is relatively more elongated. In addition, the strong, blunt seta on the axilla of A. bimaculatum is relatively longer than that of A. indochinense ; the metacoxa is brown in A. bimaculatum but pale or yellow in A. indochinense . All these distinguishing characters, however, are rather weak and could be within the range of the intraspecific variability of A. indochinense . More specimens are needed before any further decisions about the conspecificity of these two taxa are made.

Distribution India, Indonesia [new record], and Taiwan [new record].
