ANAGRUS Haliday, 1833

( Figs 21–37 )

Anagrus Haliday, 1833a: 268 ; 1833b: 346. Type species: Ichneumon atomus Linnaeus, 1767 , by subsequent designation by Westwood, 1839: 78. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Face without subantennal sulci ( Figs 21 , 26 , 33 ); ocelli usually (except in subgenus Anagrella ) delimited by stemmaticum ( Fig. 33 ); female antenna with clava 1-segmented ( Figs 23 , 27 , 34 ), in lateral view often clearly asymmetrical, with dorsal margin usually strongly curved and ventral margin almost straight ( Figs 23 , 27 ); frenum longitudinally divided by narrow or wide sulcus into paramedial plates, each shorter than wide ( Figs 22 , 29 , 36 ); ovipositor and sheaths not extending forward under mesosoma.

Discussion. Anagrus belongs to the Anagrus group of genera. In the Afrotropical region this group also includes Allanagrus , Dorya , Omyomymar , Paranaphoidea and Schizophragma . The Afrotropical region has species in the three subgenera: A. ( Anagrus ), A. ( Anagrella ) and A. ( Paranagrus ). Members of the atomus species group of A. ( Anagrus ) are dominant and very diverse in the entire continent ( Triapitsyn et al. 2020b), while the subgenus A. ( Anagrella ) is quite speciose in the humid environments of tropical continental Africa ( Triapitsyn 2015).

Afrotropical hosts. Hemiptera .
