Name

Arescon gaoligongensis Jin & Li sp. n.Wikispecies linkZooBank linkPensoft Profile

Holotype

♀ (NEFU) Yunnan Province, Baoshan City, Mt. Gaoligong, Baihualing, 31. VII.2014–2.VIII. 2014, Hui-Lin Han, YPT.

Diagnosis

Clava (Fig. 2) 2.93× as long as wide, longer than scape; metanotum (Fig. 3) with dorsellum rhomboidal; propodeum distinctly shorter than scutellum; phragma broad with posterior margin nearly straight; fore wing (Fig. 4) 3.93× as long as wide, with venation extending 0.7× length of wing; discal setation rather sparse, with about 7 or 8 rows of setae at the broadest part of wing; base of the wing behind submarginal vein asetose; ovipositor (Fig. 6) distinctly exserted, 2.12× as long as metatibia.

Description

Female (Holotype). Body length 756. Head yellowish brown with eye, ocelli, middle part of transverse trabecula, supraorbital trabecula and mandible dark brown. Antenna yellowish brown with radicle, scape, pedicel and fl1 paler. Mesosoma largely yellowish brown except a large round spot on about anterior two fifths and two relatively small spots on lateral margins of mesoscutum, a small spot on each axilla anteriorly, dark brown. Wings slightly infuscated, with venation brown. Legs brown with basal parts of coxae, apical parts of femora and last tarsal segments paler. Metasoma pale brown with exerted part of ovipositor darker.
Head. Head (Fig. 1) width 168. Vertex and face with faint reticulate sculpture.
Antenna. Antenna (Fig. 2) sparsely setose. Radicle 0.46× as long as scape; scape about 3.5× as long as wide, with distinct striations which are more or less transverse on base and gradually become oblique distad; pedicel with faint longitudinal striations, about 2× as long as wide, and 2× as long as fl1; all funicular segments much longer than wide, fl1 distinctly shortest, without mps; fl2 slightly longer than fl3, with 1 mps; fl3 about as long as fl4 each with 2 mps; fl5 slightly shorter than fl4, with 2 mps; clava 2.93× as long as wide, longer than scape, shorter than fl4 and fl5 combined, divided into 3 segments ventrally by 2 incomplete oblique septa, with 6 mps. Measurements (length/width): radicle 38, scape 84/24, pedicel 48/24, fl1 24/13, fl2 82/17, fl3 72/17, fl4 72/17, fl5 67/19, clava 98/34.
Mesosoma. Mesosoma (Fig. 3) length 277. Pronotum entire, with faint longitudinal striations. Mesoscutum with longitudinal reticulate sculpture on mid lobe and isodiametric reticulate sculpture on lateral lobes. Scutellum transverse, distinctly shorter than mesoscutum (30: 51); anterior scutellum (14: 33) subrectangular, with campaniform sensilla a little nearer to lateral margin than to each other. Metanotum with dorsellum rhomboidal. Propodeum smooth, distinctly shorter than scutellum. Phragma broad with posterior margin nearly straight.
Wings. Fore wing (Fig. 4) length 584, width 149, length/width 3.93, with venation extending 0.7× length of wing; longest marginal setae 152, 1.02× as long as greatest wing width. Fore wing base behind submarginal vein without setae, disc behind basal half of marginal vein with 2 or 3 irregular rows of setae, remaining disc distal to middle of marginal vein with 7 or 8 irregular rows of setae and a bare strip present along about distal one third of posterior margin. Hind wing (Fig. 5) length 545, width 17, length/width 32.4, longest marginal setae 101, about 6× as long as greatest wing width.
Metasoma. Metasoma (Fig. 6) distinctly longer than mesosoma. Petiole short. Gaster (376) with ovipositor length 495, distinctly exserted, 2.12× as long as metatibia (233).

Host

Unknown.

Etymology

The specific name is derived from the name of the collection locality of the type species.

Comments

Arescon gaoligongensis sp. n. is similar to Arescon iridescens, but can be distinguished from it by the key given above. The new species is also similar to Arescon enocki (Subba Rao & Kaur) in relatively longer fore wing venation and fore wing disc setation, but can be distinguished from it by the relatively shorter clava, 2.9× as long as wide, shorter than fl4 and fl5 combined (clava relatively longer, 4.0× as long as wide, much longer than fl4 and fl5 combined in Arescon enocki); broader fore wing, 3.9× as long as wide (much narrower, 4.5× as long as wide in Arescon enocki); and the ovipositor characters, ovipositor originated from base of gaster, distinctly exserted (ovipositor originated from distal part of gaster, and slightly exserted in Arescon enocki).
