ACMOPOLYNEMA Ogloblin, 1946

( Figs 1–5 )

Acmopolynema Ogloblin, 1946: 286 . Type species: Stichothrix bifasciatipennis Girault, 1908 , by original designation. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Face without or with faint subantennal sulcus ventral to each torulus and without a pit medially next to each torulus ( Fig. 1 ); toruli separated by at least their own height from transverse trabecula; propleura widely abutting each other anterior to prosternum; fore wing usually with one or two dark transverse band distal to venation, the bands usually with some discal setae with enlarged bases ( Fig. 3 ); parastigma without a proximal macrochaeta but with a distal macrochaeta, and marginal vein absent; petiole attached posteriorly to gs 1; propodeum with Vshaped median carinae ( Fig. 4 ).

Remarks. Acmopolynema belongs to the Polynema group of genera. Acmopolynema has a short transverse trabecula extending medially anterior to each lateral ocellus that appears to be unique. The V- shaped propodeal carinae (rarely very short) are also unique.

Neotropical hosts. Hemiptera : Cercopidae , Delphacidae , Membracidae .
