Diagnosis. Body length 760–2500 μm. Face with torulus separated from transverse trabecula by about twice its own diameter ( Figs 2 View FIGURES 2–5 , 13 View FIGURES 13–18 ); propleura abutting medially anterior to prosternum ( Fig. 21 View FIGURES 19–26 ); propodeum with V- shaped median carinae ( Figs 8 View FIGURES 7, 8 , 19, 23 View FIGURES 19–26 ); fore wing usually with dark transverse bands ( Figs 1 View FIGURE 1 , 7a View FIGURES 7, 8 ), sometimes without ( Fig. 7b View FIGURES 7, 8 ) and with some discal setae (especially on dark bands when present) modified, with enlarged bases; petiole distinctly longer than wide ( Figs 9 View FIGURES 9, 10 , 12 View FIGURES 11, 12 , 24–26 View FIGURES 19–26 ), ventrally with longitudinal suture, and apparently attached to gs 1 ( Figs 11, 12 View FIGURES 11, 12 , 29 View FIGURES 27–30 ).

Discussion. Acmopolynema belongs to the Polynema group of genera as defined and keyed by Triapitsyn & Berezovskiy (2007). Among the nine other Nearctic genera of the Polynema group ( Caraphractus , Cnecomymar , Eustochus , Kalopolynema , Mymar , Neomymar , Palaeoneura , Polynema , Stephanodes ), Acmopolynema is unique in having the propodeal carinae V- shaped. Acmopolynema species with clear wings, e.g., A. immaculatum Schauff , are most likely to be confused with Polynema species. The largest Nearctic species of Mymaridae , A. varium (Girault) at 2.5 mm in length, is classified in Acmopolynema .

Nearctic hosts. Cercopidae , Cicadellidae , Hemiptera : Orthoptera : Oecanthidae .

Important references. Schauff (1981) and Fidalgo (1989) treated the Nearctic and Neotropical faunas, respectively. Yoshimoto (1990) attempted to divide the Western Hemisphere species into species groups and keyed the groups. Although only slightly relevant to the Western Hemisphere fauna, Triapitsyn & Berezovskiy (2007) provided a useful key to Polynema -group genera and treated the Oriental and Australasian species.
