Gonatocerus (Gonatocerus) appendiculatus ( Ogloblin, 1939 )


Gonatocerus (Gonatocerus) appendiculatus ( Ogloblin, 1939)

( Figs 12–16 View FIGURES 12 – 14 View FIGURES 15 – 16 )

Lymaenon appendiculatus Ogloblin 1939: 239 –241 + plate (lámina) III (illustrations). Type locality: Loreto, Misiones, Argentina.

Type material examined. Lectotype female [MLPA], here designated to avoid confusion about the status of the type specimens of this species, on slide labeled: 1. “ Gonatocerus claviger [emn, co] A. O. ♀ appendicu… [illegible, apparently added ip later] Loreto, Misiones Fig. [iR, ip] 5.ix.1932. A. O. Typus”; 2. ‘3852”; 3. [red circle] “Lectotype”. The lectotype is complete, uncleared, and mounted dorsoventrally. Paralectotypes [both MLPA]: 1 ♂ on slide labeled: 1. “ Gonatocerus appendiculatus [apparently added ip later] claviger [co] A. O. ♂ Loreto, Misiones A. A. O. 23.ix.1932 Campo Typus”, 2. ‘3851”; 1 ♂ on slide labeled: “ Gonatocerus appendiculatus [apparently added ip later] claviger [erased] ♂ Loreto, Misiones 21.v.1934 ”.

The published collection date of one of the original male syntypes (23.iv.1932) contradicts the collection date on the paralectotype slide (23.ix.1932). The latter is likely the correct one because Ogloblin apparently confused “x” with “v” in the month “ix” of this specimen’s collection date. The remaining two original syntype specimens mentioned, a female (collected 5.ix.1932) and a male (collected 21.v.1934), are missing from MLPA.

Redescription. FEMALE (lectotype). Body ( Fig. 13 View FIGURES 12 – 14 ) mostly brown; appendages mostly light brown, flagellum and metacoxa brown to dark brown, radicle yellowish.

Antenna ( Fig. 12 View FIGURES 12 – 14 ) with radicle about 4.6x as long as wide, rest of scape about 5.6x as long as wide, lightly striate; pedicel longer than F1; F1–F6 narrower than F7 or F8, F3 the longest and F4 and F6 the shortest of funicle segments; F1–F6 without mps, F7 and F8 each with 2 mps; clava incised at apex, with 8 mps, 3.6x as long as wide, longer than combined length of F4–F8.

Mesosoma. Pronotum 2-lobed (mediolongitudinally divided), not entire as drawn in Fig. 60 View FIGURES 59 – 61 by Ogloblin (1939). Dorsellum rhomboidal. Forewing ( Fig. 14 View FIGURES 12 – 14 ) about 5.2x as long as wide; longest marginal seta about 0.6x maximum wing width. Forewing disc slightly infumate, with an infuscation behind stigmal vein and apex of marginal vein, bare behind submarginal vein, sparsely setose behind marginal and stigmal veins, and almost bare just beyond stigmal vein; remainder of disc densely setose. Hind wing about 28x as long as wide; blade bare except for rows of setae along margins; longest marginal seta about 3.4x maximum wing width.

Metasoma. Petiole short, a little wider than long, trapezoidal. Ovipositor about 0.8x length of gaster, not exserted beyond its apex. Ovipositor length: mesotibia length ratio about 1.4:1.

Measurements (µm) of the lectotype. Body: total body length: 935; head 147; mesosoma 350; petiole 27; gaster 411; ovipositor 336. Antenna: radicle 70; rest of scape 136; pedicel 61; F1 39; F2 40; F3 50; F4 28; F5 30; F6 28; F7 41; F8 40; clava 205. Forewing 892:173; longest marginal seta 106. Hind wing 768:27; longest marginal seta 93.

MALE (paralectotype collected 23.ix.1932 and non-type specimen from Loreto, Misiones, collected 27.xi.1936). Body length 984–1076 µm. Similar to female except for normal sexually dimorphic features and the following. Antenna ( Fig. 15 View FIGURES 15 – 16 ) with scape minus radicle about 3.8x as long as wide. Forewing ( Fig. 16 View FIGURES 15 – 16 ) 4.8– 5.0x as long as wide.

Diagnosis. Gonatocerus (Gonatocerus) appendiculatus is characterized by the peculiar female antenna ( Fig. 12 View FIGURES 12 – 14 ) with the tip of the clava incised, thus narrow and fingerlike, and also by the narrow forewing (about 5.2x as long as wide) ( Fig. 14 View FIGURES 12 – 14 ).

Distribution. NEOTROPICAL: Argentina, and Uruguay *.

Hosts. Unknown.
