Gonatocerus (Gonatocerus) granulosus (Ogloblin, 1959) View in CoL

( Figs 31–39 View FIGURES 31, 32 )

Lymaenon (Lymaenon) granulosus Ogloblin 1959a: 189 View in CoL –192. Type locality: 25 de Mayo, Misiones, Argentina. Gonatocerus (Gonatocerus) granulosus (Ogloblin) : De Santis 1967: 104 (catalog). Gonatocerus granulosus (Ogloblin) : Yoshimoto 1990: 39 (list); Luft Albarracin et al. 2009: 9 (list; distribution in Argen-

tina).

Lymaenon granulosus Ogloblin View in CoL : Loiácono et al. 2005: 14 (type information).

Type material examined. Holotype male and allotype female [ MLPA] under the same coverslip on slide labeled: 1. “ Lymaenon granulosus A. Ogl. 25 de Mayo, Misiones 7.i.1958. V. K. B de Ogloblin Holo y allotypi”; 2. ‘3876”; 3. [red circle] “holo-type ♂ ”. The holotype male is complete, with the head collapsed, mounted dorsoventrally; the allotype female is mounted laterally.

We could not locate the specimens of G. (Gonatocerus) granulosus in MLPA (under numbers 5074/3 and 5088/3), marked by Ogloblin as “paratypes” ( Loiácono et al. 2005), but they have no type status.

Material examined. ARGENTINA. ENTRE RÍOS, Parque Nacional El Palmar, Centro de Visitantes , 31°52’00.6’’S 58°12’30.3’’W, 12-24 m, 14.ii.2009, D.A. Aquino, A.V. Ossipov, S.V. Triapitsyn [1 ♀, UCRC] GoogleMaps .

Redescription. FEMALE (allotype). Body length 873 µm. Head mostly brown, mesosoma partially light brown and partially brown, gaster light brown basally, distal gastral terga dark brown; scape light brown, pedicel brown, flagellum brown to dark brown; legs light brown to brown.

Antenna ( Fig. 32 View FIGURES 31, 32 ) with radicle about 0.4x total length of scape, rest of scape 2.6x as long as wide; pedicel longer than F1; F1, F2, and F4 subequal, narrower than other funicle segments, F3 a little longer than F2 or F4 and subequal to each of F5–F8; F3 and F5–F8 each with 2 mps; clava with 8 mps, 4.1x as long as wide, shorter than combined length of F5–F8.

Mesosoma ( Fig. 31 View FIGURES 31, 32 ). Pronotum (in non-type specimen from Parque Nacional El Palmar, Entre Ríos) 2- lobed (mediolongitudinally divided), not entire as drawn in Fig. 7 View FIGURES 5 – 7 by Ogloblin (1956). Dorsellum rhomboidal. Forewing ( Fig. 33) 4.1x as long as wide; longest marginal seta about 0.4x maximum wing width. Forewing disc slightly infumate throughout, bare behind submarginal vein, setose behind and beyond marginal vein. Hind wing 24–25x as long as wide; disc bare except for rows of setae along margins, slightly infumate throughout; longest marginal seta 3.0x maximum wing width.

Metasoma ( Fig. 31 View FIGURES 31, 32 ). Ovipositor 0.7x length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 1.1:1.

MALE (holotype). Similar to female except for normal sexually dimorphic features and the following. Gaster light brown basally and brown distally. Antenna ( Fig. 38 View FIGURES 38, 39 ) with scape (excluding radicle) 2.0x as long as wide. Forewing ( Fig. 39 View FIGURES 38, 39 ) 4.0x as long as wide.

Measurements (µm) of the holotype. Body length 738. Mesosoma 289; gaster 345. Antenna: scape (including radicle) 75; pedicel 45; F1 67; F2 71; F3 78; F4 82; F5 79; F6 77; F7 79; F8 79; F9 80; F10 79; F11 90. Forewing 867:215; longest marginal seta 79. Hind wing: 677:30; longest marginal seta 91.

Diagnosis. Gonatocerus (Gonatocerus) granulosus is characterized by the female antenna ( Fig. 32 View FIGURES 31, 32 ) bearing 2 mps on F3 and F5–F8. The illustrations of the antenna ( Fig. 34 View FIGURES 34 – 37 ), mesosoma and petiole ( Fig. 35 View FIGURES 34 – 37 ), forewing ( Fig. 36 View FIGURES 34 – 37 ), and hind wing ( Fig. 37 View FIGURES 34 – 37 ) are of the better slide-mounted non-type female specimen from Parque Nacional El Palmar, Entre Ríos, Argentina.

Distribution. NEOTROPICAL: Argentina.

Hosts. Unknown.
