The holotype is circled in black ink; it is in fair condition, perfectly spread out, mounted dorsoventrally. Paratypes of A. shajovskoii   — Argentina: Neuquén, Pucará, Lago Lácar , 21.ii.1953, 23.ii.1953, 25.ii.1953, 26.ii.1953, 27.ii.1953, V.K. Ogloblina and A.A. Ogloblin [15 ♀♀, MLPA].

[1 ♀ (PM), UCRC] GoogleMaps   , UCR ATol, meadow & Nothofagus   , MT [1 ♂, UCRC].

Diagnosis. Agalmopolynema porteri   is characterized by the following combination of features: general color light brown with petiole, scape, pedicel, and legs light brown; scape smooth; clava a little longer than combined length of 3 preceding segments, with 7 mps; pronotum divided mediolongitudinally; mesosoma smooth; propodeum with an inconspicuous, incomplete median carina at posterior margin; petiole transversely striate; fore wing hyaline; petiole attached to gastral sternum.

Although it is difficult to see whether the prosternum in the holotype is “closed” anteriorly, it is likely to be the case because this is clearly visible in the additional, conspecific material examined. We therefore assign P. porteri   to Agalmopolynema   , which is a very common genus in Chile. Position of the scutellar campaniform sensilla in this species is about in the middle of scutellum, as in many other species of Agalmopolynema   but also in the Neotropical members of Polynema   ( Doriclytus Foerster   ) ( Triapitsyn & Fidalgo 2006), but the face clearly lacks a pit next to each torulus ( Fig. 2a View FIGURES 2 ).

Redescription (holotype of A. porteri   ). Head and body brown; petiole, scape, pedicel, and legs light brown.

Antenna ( Fig. 2b View FIGURES 2 ). Scape excluding radicle about 3.5× as long as wide and smooth, slightly narrower than pedicel; F1 shorter than pedicel; F2 the longest funicular segment; F4 about as long as F6, the latter slightly longer than F5; clava about 2.7× as long as wide, a little longer than combined length of three preceding segments, with 7 mps.

Mesosoma ( Fig. 2c View FIGURES 2 ) short and smooth. Pronotum short, divided mediolongitudinally, each lobe with 1 visible short seta; mesoscutum wider than long, notauli short and wide; axillar seta short and weak; scutellum wider than long; scutellar campaniform sensilla about midway between anterior and posterior margins of scutellum and with irregular frenal row of 14–16 foveae; propodeum with inconspicuous, complete or incomplete (difficult to assess) median carina at posterior margin.

Wings ( Fig. 2e View FIGURES 2 ). Fore wing 4.1× as long as wide, rather slender beyond venation; marginal vein rather short; disc hyaline, densely setose, the discal setae numerous and comparatively short; longest marginal seta about 0.8× as long as greatest wing width. Hind wing about 30× as long as wide; disc hyaline, with a complete row of setae along each margin (not counting long and short marginal setae); longest marginal seta about 6× greatest width of wing.

Legs. Protibia with 6 conical sensilla; metacoxa sparsely setose, as long as petiole.

Metasoma ( Fig. 2d View FIGURES 2 ). Petiole transversely striate. Ovipositor longer than gaster, exserted beyond gastral apex by about 0.14× total length of ovipositor; ovipositor 1.3× length of metatibia.

Holotype measurements. Body (excluding head), 776: mesosoma, 320; gaster, 400; ovipositor, 408. Antenna: scape (including radicle), 90; pedicel, 48; F1, 42; F2, 92; F3, 70; F4, 40; F5, 38; F6, 46; clava, 134. Fore wing, 900:200; longest marginal seta, 170. Hind wing, 680:22; longest marginal seta, 136.

MALE (previously unknown, specimen from Chile). Body length: 704 (slide-mounted specimen). Similar to female except for normal sexually dimorphic features. Antenna with scape about as long as or slightly shorter than a flagellomere. Fore wing 4.5× as long as wide; longest marginal seta slightly shorter than greatest fore wing width.

Measurements. Mesosoma, 352; gaster, 264; protibia, 216; metatibia, 320. Fore wing, 909:200; hind wing, 664:19. Antenna: scape (including radicle), 83; pedicel, 54; F1, 79; F2, 92; F3, 98; F4, 96; F5, 96; F6, 92; F7, 92; F8, 87; F9, 81; F10, 83; F11, 90. Head, 171:208.

Distribution. Argentina (new record) and Chile.

Comments. Type material of A. shajovskoii   is almost identical to the holotype of A. porteri   , and hence the synonymy. However, the holotype and some other specimens of the former have the ovipositor about the same length as the metatibia, whereas the examined paratypes of A. shajovskoii   have the ovipositor 0.75–1.2× length of the metatibia, the exserted part of ovipositor can be up to 0.16× its total length, and the fore wing is 4.8× as long as wide. Consequently, these parameters in the holotype of A. porteri   almost fit the rather wide range of intraspecific variability within A. shajovskoii   .
