Nomenclature

Anagrus Haliday, 1833: 346. Type species: Ichneumon atomus Linnaeus, by subsequent designation (Westwood, 1839: 78).
Pteratomus Packard, 1864: 137. Type species: Pteratomus putnamii Packard, by monotypy. Synonymy formalized by Annecke and Doutt (1961: 7), following Girault (1929 [428]: 27).
Paranagrus Perkins, 1905: 199. Type species: Paranagrus optabilis Perkins, by subsequent designation (Gahan and Fagan, 1923: 106). Synonymy by Bakkendorf (1926).
Anagrella Bakkendorf, 1962: 372. Type species: Anagrella mymaricornis Bakkendorf, by monotypy. Synonymy by Viggiani (1970: 139).

Diagnosis

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

Female funicle 6-segmented (Fig. 8), antennal clava solid
Thorax (Fig. 9) with axillae advanced into side lobes of mesoscutum, posterior scutellum divided by a longitudinal sulcus, medially not more than twice as long as anterior scutellum
Fore wing (Fig. 10) with posterior margin behind venation only slightly lobed
Tarsi 4-segmented; protibial spur comb-like.
