ANAGRUS Haliday, 1833 View in CoL

( Figs 25–32 View FIGURES 25–27 View FIGURES 28, 29 View FIGURES 30–32 )

Anagrus Haliday, 1833a: 268 View in CoL ; 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 sulcus ventral to each torulus ( Fig. 25a View FIGURES 25–27 ); clava 1-segmented ( Figs 26 View FIGURES 25–27 , 31 View FIGURES 30–32 ), in lateral view often clearly asymmetrical, with dorsal margin usually strongly curved and ventral margin almost straight ( Fig. 26 View FIGURES 25–27 ); ocellar triangle delineated by a stemmaticum, visible as pale lines ( Fig. 28 View FIGURES 28, 29 ); frenum completely longitudinally divided by a narrow or wide sulcus into paramedial plates, each plate at most not much longer than wide ( Fig. 28 View FIGURES 28, 29 ). Species of Anagrus (Anagrus) ( Figs 25–29 View FIGURES 25–27 View FIGURES 28, 29 ) with fu 1 distinctly shorter than pedicel ( Fig. 26 View FIGURES 25–27 ); species of Anagrus (Paranagrus) ( Figs 30–32 View FIGURES 30–32 ) with fu 1 as long as pedicel ( Fig. 31 View FIGURES 30–32 ).

Remarks. Anagrus belongs to the Anagrus group of genera. Anagrus is the only genus with clava 1-segmented. Females of the other genera in the group have the clava 2- or 3-segmented. The Neotropical region has species in the three subgenera, A. ( Anagrus ), A. ( Anagrella ) and A. ( Paranagrus ) but by far the most speciose is A. ( Anagrus ).

Neotropical hosts. Hemiptera , Lepidoptera (needs confirmation), Odonata.
