Type species: Anagyrus greeni Howard , by monotypy. Subsequent important references: De Santis 1964 : 56 –59 (diagnosis, distribution, host associations, partial key to species in Argentina ); Noyes 1980 : 173 (synonymy, list of species in the Neotropical region, brief discussion); Noyes & Hayat 1994 : 69 –74 (synonymy, comments, biology); Noyes 2000 : 28 –32 (synonymy, list of species in the Neotropical region, brief discussion). Comments. Species of Anagyrus in Argentina and the entire Neotropical region can be recognized using the key in Noyes (1980) . Later, Noyes (2000) provided a useful key to females of the genera in the subfamily Tetracneminae occurring in Costa Rica and a key to Costa Rican species of Anagyrus . The key below includes 14 species of Anagyrus known so far from Argentina and also, for convenience only, A. porteri (Brèthes) from Chile . The previous such key by De Santis (1964) included only six species; De Santis (1964 , 1972 ) also had described several species in other genera which were later justifiably synonymized under Anagyrus by Noyes (1979 , 1980 , 2000 ). All known species of Anagyrus in Argentina seem to be native with the exception of A. pseudococci (Girault) s. str. , which was likely unintentionally introduced with grape seedlings from Italy ( Triapitsyn et al. 2007 ).
