Gonatocerus (Gastrogonatocerus) valentinae (Ogloblin, 1959)

(Not included in the key)

( Figs 143–146 )

Lymaenon (Lymaenon) valentinae Ogloblin 1959a: 192 –195. Type locality: Establecimiento “ Los Indios ” (? Camping Paraje Los Indios), Oberá, Misiones, Argentina.

Gonatocerus (Gonatocerus) valentinae (Ogloblin) : De Santis 1967: 105 (catalog).

Lymaenon valentinae Ogloblin : Loiácono et al. 2005: 14 (type information).

Gonatocerus valentinae (Ogloblin) : Yoshimoto 1990: 41 (list); Luft Albarracin et al. 2009: 10 (list; distribution in Argentina).

Type material examined. Holotype male [ MLPA] on slide labeled: 1. [in pencil] “-Obera. ♂ 7.i.1958 V. d Ogloblin ♂ Lymaenon valentinae Holotypus ”; 2. “5077/1 Holotipo ♂ Lymaenon valentinae ”. The holotype is uncleared, in poor condition but complete, with the body collapsed, mounted at an angle ( Fig. 144 ).

Redescription. FEMALE. Unknown.

MALE. Body mostly dark brown except base of gaster light brown; antenna brown, legs light brown to brown.

Antenna ( Fig. 143 ) with scape plus radicle about 2.4x as long as wide.

Mesosoma. Mesoscutum and scutellum long, with weak sculpture; dorsellum apparently semi-rhomboidal; propodeum with two conspicuous, subparallel submedian carinae extending almost to its anterior margin but not touching it, propodeal spiracle not very large, normal in size. Forewing ( Fig. 146 ) 3.3x as long as wide; longest marginal seta about 0.2x maximum wing width; forewing disc with a very slight brownish tinge, almost hyaline; bare behind venation except for 2–4 setae just behind stigmal vein, and just beyond apex of venation along anterior margin, but setose elsewhere. Hind wing ( Fig. 146 ) about 16x as long as wide; disc with a row of setae along each margin and an additional, incomplete row of setae between them, almost hyaline; longest marginal seta 1.6x maximum wing width. Genitalia hardly visible ( Fig. 145 ).

Measurements (µm) of the holotype. Body length 1353 [the head is twisted; Ogloblin (1959a) gave the body length as 1227]; mesosoma 523; gaster 584. Antenna: scape plus radicle 100; pedicel 58; F1 85; F2 100; F3 102; F4 103; F5 103; F6 103; F7 100; F8 97; F9 100; F10 100; F11 114. Forewing 1162:350; longest marginal seta 70. Hind wing 861:55; longest marginal seta 88.

Diagnosis. We treat G. valentinae , known from the holotype only, as a member of G. ( Gastrogonatocerus ) mainly based on the apparently semi-rhomboidal shape of the dorsellum, the sparse setation on the forewing, and the structure of the male genitalia, as illustrated by Ogloblin (1959a). Until a female can confidently be assigned to this species its subgeneric placement and identity will remain doubtful.

Distribution. NEOTROPICAL: Argentina.

Hosts. Unknown.
