( Figs 457 –463)

Lymaenon schajovskoii Ogloblin 1957: 37 –38 + unnumbered plate page 1 (illustrations). Type locality: Pucará (at Lago Lácar), Neuquén, Argentina.

Type material examined. Holotype female [ MLPA] on slide labeled: 1. “ R.S. 3 at/ Ant. Thor. [ip] Lymaenon shajovskoii [sic] A. Ogl. ♀ Pucará , Lago Lacar, Territ. de Neuquen. 25–ii–1953. V. K. O. y A. A. O . Typus n. 1 Holotyp. [ip]”; 2. “5076/1”. The holotype is in good condition, mounted dorsoventrally, perfectly spread out, complete. Paratypes [all MLPA]: 1 ♀ on slide labeled: 1. “sin R.S. [ip] Lymaenon shajovskoii [sic, ip] ♀ Pucará. Lago Lacar. Terr. de Neuquen 25.II.1953. V. K. y A. O. n 2. [ip]” ; 1 ♀ on slide labeled: 1. “? R.S. 3 at [ip] Lymaenon shajovsk [sic, ip] ♀ Pucará, Lago Lacar. Terr. Nac. de Neuquen 23.II.1953. n 7 [ip] A. O. y V. B. de. Ogl. ” ; 1 ♀ on slide labeled: 1. “sin R.S. 2 [ip] Lymaenon shajovskoii [sic, ip] ♀ Pucara, Lago Lacar Terr. N. de Neuquen n. 6.”.

The species was described from 5 females, all collected in Pucará (at Lago Lácar, Neuquén Province) in February and March of 1953 and 1954. Of these, only one paratype is missing from MLPA, although it is possible, although not likely, that one of the apparently non-type specimens from Ogloblin’s collections from Pucará listed below could be that paratype. If so, it would be the specimen without a collection date.

FIGURES 460–463. Gonatocerus (Cosmocomoidea) schajovskoii ♂ (37°48’58’’S 73°00’36’’W, Parque Nacional Nahuelbuta, Región IX, Chile): 460, antenna; 461, dorsellum and propodeum; 462, genitalia; 463, wings.

Redescription. FEMALE (holotype, first listed paratype, and non-type specimens). Body length 960– 1350 µm. Body ( Fig. 458 ) mostly dark brown except gaster mostly brown with base often a little, and sometimes significantly lighter; antenna dark brown except pedicel a little lighter (brown); legs light brown to brown.

Antenna ( Fig. 457 ) with radicle a little more than 0.25x total length of scape, remainder of scape 3.0–3.1x as long as wide, slightly longitudinally striate; pedicel longer than F1; F2 longer than F1 and more or less subequal in length to F3–F5; F6 usually a little shorter than F5, F7 usually a little shorter than F6, and F8 a little shorter than F7; F1–F3 without mps; F4 usually with 1 mps, occasionally with 2 mps, but often without mps; F6 usually with 2 mps but sometimes with just 1 mps; F5, F7, and F8 each with 2 mps; clava 2.6–3.3x as long as wide, with 8 mps, usually a little shorter than combined length of F6–F8 but sometimes almost as long as their combined length.

Mesoscutum and scutellum with weak sculpture (best seen in dry specimens). Propodeum with more or less thick, subparallel, widely separated submedian carinae almost extending to but not touching anterior margin. Forewing ( Fig. 459 ) broad, 2.9–3.2x as long as wide; longest marginal seta usually about 0.2x, sometimes up to 0.25x maximum wing width; disc with a slight brownish tinge throughout, almost hyaline, bare behind submarginal vein and densely setose elsewhere, including behind marginal and stigmal veins anterior to cubital row of setae. Hind wing ( Fig. 459 ) 14–17x as long as wide; longest marginal seta 1.7–2.0x maximum wing width; disc setose (more sparsely behind venation), with a very slight brownish tinge (almost hyaline).

Petiole subtrapezoidal, 1.7–1.9x as wide as long. Gaster at least a little longer than mesosoma; ovipositor rather short, 0.6–0.7x length of gaster, not or barely exserted beyond apex of gaster by at most 0.1x own length; 0.9–1.2x as long as mesotibia.

Measurements (µm) of the holotype. Total body length 1242; head 215; mesosoma 492; petiole 86; gaster 540; ovipositor 378. Antenna: radicle 52; rest of scape 136; pedicel 61; F1 45; F2 84; F3 87; F4 90; F5 82; F6 76; F7 73; F8 61; clava 200. Forewing 1396:470; longest marginal seta 91. Hind wing 1039:66; longest marginal seta 112.

Description. MALE (previously unknown, non-type specimens from Chile). Body length 1056–1335 µm. Similar to female except gaster more or less concolorous with the rest of body, and antenna (Fig. 460) brown. Propodeum as in Fig. 461. Forewing (Fig. 463) 2.8–2.9x as long as wide. Genitalia (Fig. 462) typical of the ater species group of G. ( Cosmocomoidea ).

Diagnosis. Gonatocerus (Cosmocomoidea) schajovskoii is a member of the chusqueicolus subgroup of the ater species group. It is very similar to the smaller G. (Cosmocomoidea) carahuensis (Ogloblin) , from which it differs by the wider and thicker propodeal submedian carinae (particularly anteriorly) (Fig. 461), relatively longer F2–F4 and shorter F8 of the female antenna ( Fig. 457 ), usually a little wider forewing ( Figs 459 , 463), and also by the usually lighter color of the gaster, which is somewhat lighter than the mesosoma ( Fig. 458 ).

Distribution. NEOTROPICAL: Argentina, and Chile *.

Hosts. Unknown.
