Gonatocerus valentinae

description: 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.
