description: Anagyrus montivagus (De Santis, 1964)   
(Figs 30–33)  
 Leptomastix montivagus De Santis 1964: 86 –88. Type locality: Potrillo Oscuro [as Potrillo Obscuro], La Pampa, Argentina. Subsequent references: De Santis 1967: 152 (catalog); Loiácono et al. 2001: 154 (type information).   
 Apoanagyrus montivagus (De Santis): Noyes 1980: 176 (brief discussion); Kerrich 1982: 413 (discussion), 415 (key); Noyes & Hayat 1994: 305 (revived combination).   
 Epidinocarsis montivagus (De Santis): Noyes & Hayat 1984: 273.   
 Epidinocarsis diversicornis (Howard): De Santis 1989: 31 –32 (misidentification of specimens from Argentina).   
 Anagyrus montivagus (De Santis): Noyes 2000: 29, 71 (mentioned).   
 Type material examined. Holotype female [MLPA] on slide (Fig. 30) labeled: 1. “POTRILLO OBSCURO (Prov. de La Pampa) col: Exp. Museo 27/I/1958 ♀ [in pencil]”; 2. “ Leptomastix montivagus Det. De Santis HOLOTIPO 1936/1 [MLPA type number added later] MUSEO DE LA PLATA ”. The holotype is in fair condition, with head plus one antenna (Fig. 31) detached from the body (Fig. 32), and the other antenna detached from the head.   
 Distribution. Argentina: Autonomous City of Buenos Aires and La Pampa (De Santis 1964, 1967), and also Misiones (De Santis 1989 [as Epidinocarsis diversicornis (Howard)].   
 Hosts. Unknown.   
 Taxonomic notes. This species was described from the holotype and two female paratypes (De Santis 1964). In the holotype, the scape is mostly dark except light apically; F1 is distinctly longer than F2; F2 is whitish and contrasts with the other dark brown funicular segments (Fig. 31). Both Noyes (1980, 2000) and Kerrich (1982) considered the possibility that A. montivagus might be a mere color form of, and thus likely synonymous with, A. diversicornis. Although this is possible, we are unable to assess intraspecific variation within A. diversicornis properly. Therefore, for practical reasons, we prefer to keep A. montivagus as a valid taxon, separating the two putative species based on the proportions of the fore wing, as follows. In the holotype of A. montivagus, the fore wing (Fig. 33) is about 3.0× as long as wide, whereas in A. diversicornis it is about 2.5× as long as wide (Noyes 2000). De Santis (1989: 31–32) reported A. diversicornis from Loreto, Misiones, Argentina. We examined 3 females [MLPA] determined by him (collected 3.i.1931 and 20.vi.1933 by A.A. Ogloblin) and conclude that they rather belong to A. montivagus because their fore wings are 2.9–3.28× as long as wide and leg coloration is about the same as for the holotype of this species.   
  Anagyrus porteri (Brèthes, 1921)  (extralimital, included in the key) (Figs 34–36)   
 Gyranusia Porteri [sic] Brèthes 1921: 138 –139. Type locality: Lampa, Santiago Metropolitan Region, Chile.   
 Gyranusia porteri Brèthes: De Santis 1950: 54 (holotype information, synonymy of Gyranusia Brèthes under Paranusia Brèthes).   
 Paranusia porteri (Brèthes): De Santis 1979: 11, 243.   
 Anagyrus porteri (Brèthes): Noyes 1980: 173.   
 Type material examined. Holotype female (Fig. 34) [MACN] on card labeled: 1. “Prof Porter. s/sauce cu-bierto de pul-gones.—Lampa, 17 de Mayo, 1920”; 2. “Lampa 17.v. 920 C. E. Porter”; 3. “ Gyranusia porteri Brèthes ”; 4. “ type!” except for one antenna (Fig. 35) [MACN] on slide labeled: 1. “Museo arg. C. Naturales sección ENTOMOLOGIA CHILE Lampa, 17-V- 920 C. E. Porter leg. No. 1336 – 33 [in pencil]”; 2. “ Gyranusia porteri Brèthes HOLOTYPUS [red] CHILE [faint]”.   
 Distribution. Chile (Brèthes 1921).   
 Hosts. Unknown; according to the label, it was collected from a willow covered by aphids.   
 Taxonomic notes. This species was described from a single female. The flagellum has F6 and the clava white (Figs 34, 35), and the fore wing (Fig. 36) has three dark, transverse bands on the disc. The basal band behind the submarginal vein is very wide, the middle band behind the marginal and stigmal veins is narrow, and the apical band at wing’s apex is broader than the middle but narrower than the basal band.
