Nomenclature

Acmopolynema Ogloblin, 1946: 286. Type species: Stichothrix bifasciatipennis Girault, by original designation.
Grangeriella Soyka, 1956: 17. Type species: Grangeriella indochinensis Soyka by original designation. Synonymy by Hayat and Anis (1999b: 297).
Neonarayanella Husain and Farooqi, 1996: 83. Type species: Maidliella orientalis Narayanan, Subba Rao and Kaur, by original designation. Synonymy by Hayat and Anis (1999b: 297).
Baburia Hedqvist, 2004: 235. Type species: Baburia narendrani Hedqvist, by original designation. Synonymy by Triapitsyn and Berzovskiy (2007: 6).

Diagnosis

Acmopolynema belongs to the Polynema group of genera and can be identified by the following combination of characters:

Female antenna (Fig. 10) with funicle 6-segmented
Face (Fig. 9) without a pit next to each torulus; mandible tridentate
Propodeum with V-shaped submedian carinae (Fig. 13), rarely with a single, complete or incomplete medial groove extending from the anterior margin of propodeum (Fig. 15) (Triapitsyn and Berezovskiy, 2007)
Fore wing (Fig. 11) with discal microtrichia often thickened at their base or sometimes otherwise modified
Petiole (Fig. 17) attached to gastral sternum

Lin et al. (2007) and Triaptsyn and Berezovskiy (2007) have provided diagnostic accounts of Acmopolynema with illustrations. Hayat & Anis (1999) have dealt with the Indian species and keyed them.
