Abstract: ANAGRUS Haliday, 1833 (Figs 25–32) 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 sulcus ventral to each torulus (Fig. 25a); clava 1-segmented (Figs 26, 31), in lateral view often clearly asymmetrical, with dorsal margin usually strongly curved and ventral margin almost straight (Fig. 26); ocellar triangle delineated by a stemmaticum, visible as pale lines (Fig. 28); frenum completely longitudinally divided by a narrow or wide sulcus into paramedial plates, each plate at most not much longer than wide (Fig. 28). Species of Anagrus (Anagrus) (Figs 25–29) with fu 1 distinctly shorter than pedicel (Fig. 26); species of Anagrus (Paranagrus) (Figs 30–32) with fu 1 as long as pedicel (Fig. 31). 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. Important references. Triapitsyn (2002a, 2015a).
