ANAGRUS Haliday, 1833 View in CoL View at ENA

( Figs 86–119 View FIGURE 86 View FIGURES 87–89 View FIGURES 90–93 View FIGURES 94, 95 View FIGURES 96, 97 View FIGURE 98 View FIGURES 99–101 View FIGURES 102, 103 View FIGURES 104–109 View FIGURES 110–114 View FIGURES 115–119 )

Anagrus Haliday, 1833a: 268, 1833b: 346 View in CoL . Type species: Ichneumon atomus [as atomos ] Linnaeus, 1767, by subsequent designation by Westwood, 1839: 78.

Pteratomus Packard, 1864: 137 View in CoL . Type species: Pteratomus putnamii Packard, 1864 , by monotypy. Synonymy by Girault, 1929 [428]: 27; fixed by Annecke & Doutt, 1961c: 7.

Packardiella Ashmead, 1904: 364 View in CoL . Unnecessary replacement name, proposed without apparent reason (name not preoccupied) according to Gahan & Fagan, 1923: 103 and Peck, 1963: 896.

Paranagrus Perkins, 1905: 199 View in CoL . Type species: Paranagrus optabilis Perkins, 1905 , by original designation. Synonymy implied by Bakkendorf, 1926: 258; fixed by Annecke & Doutt, 1961c: 7.

Anagrella Bakkendorf, 1962: 372 View in CoL . Type species: Anagrella mymaricornis Bakkendorf, 1962 , by monotypy. Synonymy by Viggiani, 1970: 139.

Diagnosis. Body length 300–800 μm. Face without subantennal sulci ( Fig. 87 View FIGURES 87–89 ); ocelli usually (except subgenus Anagrella ) delimited by stemmaticum ( Fig. 107 View FIGURES 104–109 ); clava 1-segmented (entire), in lateral view often clearly asymmetrical, with dorsal margin usually strongly curved and ventral margin almost straight ( Figs 86 View FIGURE 86 , 89 View FIGURES 87–89 , 98 View FIGURE 98 , 100 View FIGURES 99–101 ); mandible with 3 teeth ( Fig. 109 View FIGURES 104–109 ); frenum longitudinally divided by narrow or wide sulcus into two lobes, each lobe shorter than wide ( Figs 90 View FIGURES 90–93 , 102, 103 View FIGURES 102, 103 , 110, 114 View FIGURES 110–114 ).

Discussion. Four other genera in the Nearctic have a longitudinally divided frenum: Krokella , Platystethynium (Platypatasson) , Schizophragma and Stethynium ; Omyomymar may have an incompletely divided frenum. Females of all of them differ from Anagrus females by having the clava 2- or 3-segmented.

Considerable literature exists on various species of Anagrus because of their actual or potential use as biological control agents of economically important insects. Older references to various species of Anagrus may well be based on completely or partly incorrect identifications, e.g., specimens identified as A. armatus before Chiappini et al. (1996) and Triapitsyn (1998, 2014c). The older references are cited under the presumed correct name where this could be determined to complete the titles and journal references, mostly those in Peck (1963) or Burks (1979). Three subgenera, A. ( Anagrus ), A. ( Anagrella ) and A. ( Paranagrus ), are currently recognized.

Nearctic hosts. Hemiptera : Cercopidae , Cicadellidae , Cixiidae , Delphacidae , Miridae , Tingidae . Odonata : Coenagrionidae , Lestidae .

Important references. Gordh & Dunbar (1977) keyed the Nearctic species, Chiappini et al. (1996) treated the Holarctic fauna, Triapitsyn (1997, 2002a) reviewed the species in America south of the United States, Triapitsyn & Beardsley (2000) treated the species of the Hawaiian Islands, Triapitsyn (2001) reviewed the species in the Australasian region, Triapitsyn (2015b) gave an annotated key and catalogue to the world fauna, and Chiappini & Lin (1998) and Li et al. (2018) keyed the species of China.
