Gonatocerus (Cosmocomoidea) parcepilosus ( Ogloblin, 1957 )


Gonatocerus (Cosmocomoidea) parcepilosus ( Ogloblin, 1957)

( Figs 424 View FIGURES 424 – 426 –432)

Lymaenon parcepilosus Ogloblin 1957: 35 –36 + unnumbered plate pages 1 and 3 (illustrations). Type locality: Pucará (at Lago Lácar), Neuquén, Argentina.

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

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

Gonatocerus parcepilosus (Ogloblin) : Luft Albarracin et al. 2009: 10 (list; distribution in Argentina).

Type material examined. Holotype female [ MLPA] on slide labeled: 1. “ Lymaenon parcepilosus A. O. [ip] ♀ Pucará, Lago Lacar, Territ. de Neuquen. 25.ii.1953. V. K. y A. A. O. Typus [ip]”; 2. “5075/1”. The holotype is in poor condition as follows: body mounted at an angle ( Fig. 425 View FIGURES 424 – 426 ); gaster collapsed; flagellum of one antenna, many leg segments and all wings but one forewing detached from body (altogether there are 3 forewings on the slide, all but one in bad condition); a part of the ovipositor appears to be broken off. The collecting date on the label of this specimen does not fully agree with the published date (23.ii.1953).

Material examined. CHILE. REGIÓN VIII, Trancas (72 km SE of Chillán, near Termas), 1700 m, 6.xii.1984 – 19.ii.1985, S. & J. Peck [1 ♀, CNCI]. REGIÓN IX: Parque Nacional Nahuelbuta : 37°49’30’’S 72°58’24’’W, 1168 m, 10–24.ii.2005, J.M. Heraty et al. [3 ♀, 3 ♂, UCRC] GoogleMaps ; 37°49’42’’S 73°00’39’’W, 1138 m, 8–9.ii.2005, J.M. Heraty et al. [1 ♀, UCRC].

FIGURES 427–429. Gonatocerus (Cosmocomoidea) parcepilosus ♀ (37°49’30’’S 72°58’24’’W, Parque Nacional Nahuelbuta, Región IX, Chile): 427, antenna; 428, mesosoma and metasoma; 429, forewing.

Redescription. FEMALE (holotype and non-type specimens). Body length 1020–1380 µm. Head and mesosoma dark brown, metasoma and legs brown to dark brown; radicle brown, remainder of antenna dark brown.

Antenna ( Figs 424 View FIGURES 424 – 426 , 427) with radicle about 0.25x total length of scape, rest of scape 3.1–3.5x as long as wide, longitudinally striate; pedicel longer than F1; F1 and F2 shorter than following funicle segments (F2 slightly longer than F1) and without mps; F3–F7 subequal in length, F8 a little shorter; F3–F8 each with 2 mps; clava with 8 mps, 3.4–3.8x as long as wide, a little longer than combined length of F6–F8.

Mesosoma ( Figs 425 View FIGURES 424 – 426 , 428). Mesoscutum and scutellum with faint sculpture; propodeum with fine, subparallel submedian carinae not extending to anterior margin of propodeum, otherwise smooth. Forewing ( Figs 426 View FIGURES 424 – 426 , 429) 3.1–3.2x as long as wide; longest marginal seta about 0.2x maximum wing width; disc with a slight brownish tinge and an inconspicuous, faint, slightly darker spot behind marginal and stigmal veins, mostly bare behind venation except for 8–12 setae just behind marginal and stigmal veins, most of them more or less arranged in 1 or 2 irregular rows extending the length of marginal and stigmal veins, and densely setose elsewhere. Hind wing 17–19x as long as wide; disc with 2 rows of setae along margins and an additional, sometimes incomplete row of setae between them closer to anterior margin; almost hyaline but with a slight brownish tinge apically; longest marginal seta 1.6–2.1x maximum wing width.

Petiole about 1.6x as wide as long; gaster longer than mesosoma; ovipositor about 0.7x length of gaster, not or at most barely exserted beyond apex of gaster; about 1.2x as long as mesotibia.

FIGURES 430–432. Gonatocerus (Cosmocomoidea) parcepilosus ♂ (37°49’30’’S 72°58’24’’W, Parque Nacional Nahuelbuta, Región IX, Chile): 430, antenna; 431, forewing; 432, genitalia.

Measurements (µm) of the holotype. Total body length 1132; head 172; mesosoma 424; gaster 553. Antenna: radicle 46; rest of scape 124; pedicel 55; F1 32; F2 35; F3 58; F4 60; F5 59; F6 57; F7 57; F8 52; clava 188. Forewing 1076:345; longest marginal seta 70. Hind wing 880:52; longest marginal seta 85.

Description. MALE (previously unknown, non-type specimens). Body length 990–1320 µm. Otherwise similar to female except for normal sexually dimorphic features and the following. Antenna (Fig. 430) dark brown, with scape, including radicle, 1.5–1.6x as long as wide. Forewing (Fig. 431) 3.1–3.2x as long as wide. Genitalia as in Fig. 432.

Diagnosis. Gonatocerus (Cosmocomoidea) parcepilosus is a member of the bucculentus subgroup of the ater species group. It is very similar to G. (Cosmocomoidea) bonariensis (Brèthes) , from which it differs by the back of the head having the occipital sulcus round and slightly wider than high (oval and slightly higher than wide in G. bonariensis ), and also by the relatively longer F1, F2, and F3 of the female antenna ( Figs 424 View FIGURES 424 – 426 , 427). F3 is about as long as F 4 in G. parcepilosus and bears 2 mps, whereas it is distinctly shorter than F4 and bears just 1 mps in G. bonariensis .

Distribution. NEOTROPICAL: Argentina, and Chile *.

Hosts. Unknown.
