sp. nov.

Soita infuscata Chen & Norrbom , new species.

( Figs.127–134 View FIGURES 127 – 134 )

Soita View in CoL sp. Norrbom & Hancock, 2004: 76.

Diagnosis. Head yellow, with distinct narrow medial brown stripe on frons. Scutum mostly pale brown, but with broad medial postsutural yellowish area. Anepisternum and katepisternum without short black spines along anteroventral margin. Wing yellow, with pterostigma dark brown, apices of radial cells and mark on crossvein DM- Cu pale brown. Abdomen with syntergite 1+2 and tergite 3 yellow and tergites 4 and 5 dark brown; tergites 3 and 4 each with pair of outstanding submedial posterior setae.

Description. Male: body length 8.8 mm, wing length 6.0 mm.

Head ( Figs. 132–133 View FIGURES 127 – 134 ): Yellow except frons with distinct narrow medial brown stripe and ocellar tubercle dark brown to black; antenna and labella yellow-brown to brown. Head almost as long as high, with eye nearly round, frons gently sloping, antenna situated at middle of head, and face short. Occiput moderately swollen. Frons not parallel-sided, margins slightly convergent anteriorly. Antenna distinctly longer than face, with 1st flagellomere rounded dorsoapically, about 3 times as long as wide; arista plumose, longest ray about 1/3 width of 1st flagellomere. One pair of strong orbital setae (orbital seta itself lost, but socket distinctly larger than frontal seta socket) and 2 pairs frontal setae; orbital seta at about anterior 2/5 of frons, frontal setae close to each other and near anterior margin of frons, aligned just posterior to posterior margin of lunule. Vertical setae present (medial vertical setae lost, but sockets obvious), ocellar seta small and hairlike, genal seta absent.

Thorax ( Figs. 130–131 View FIGURES 127 – 134 ). Entirely yellow to brown. Transverse suture complete (middle part hidden by pin). Metathoracic, postcoxal bridge heavily sclerotized. Scutum mostly brown, but broadly yellowish medially posterior to transverse suture; almost parallel-sided, about 3 times as long as wide. Scutellum yellow, very short, less than half as long as wide, with 1 pair of setae. Anepisternum and katepisternum without short black spines along anteroventral margin. Other thoracic setae: 1 postpronotal, 2 notopleural, 1 postsutural supra-alar, 1 postalar, 1 intra-alar and 1 dorsocentral setae present and black.

Wing ( Fig. 128 View FIGURES 127 – 134 ). Mostly pale yellowish. Pterostigma dark brown and about half as long as cell c. One broad diffuse brown mark covering apical sixth of wing including apices of veins R2+3, R4+5 and M, another diffuse brown mark covering apex of vein Cu1 and most of crossvein DM-Cu. Vein R4+5 densely setulose dorsally from base to apex. Vein Cu1 setulose dorsally from base to slightly proximal to crossvein R-M. Legs. Fore leg yellow to yellowbrown (mid and hind legs lost).

Abdomem ( Fig. 134 View FIGURES 127 – 134 ). Syntergite 1+2 and tergite 3 yellow, tergites 4–5 dark brown. Tergites 3 and 4 each with pair of outstanding submedial posterior setae, tergite 5 with large posterior setae missing (but large sockets present). Tergites 3 and 4 about same length, tergite 5 slightly longer than tergite 4.

Female: Unknown.

Distribution. New Caledonia.

Type data: Holotype ♂ ( INHS), NEW CALEDONIA: Prov. Sud, 9.3 km NW Sarraméa, 21º35′04″S, 165º47′18″E, 445 m, Malaise trap along forest path, 23 January 1996, M.E. Irwin, D.W. Webb & E.I. Schlinger.

Etymology. The name of this species is an adjective referring to the infuscated apical area of the wing.

Remarks. This species is generally similar to S. psiloides , differing from it by the yellow wing, with the apices of the radial cells infuscated; abdomen with tergites 3 and 4 having a pair of outstanding submedial posterior setae, and head yellow, with a distinct narrow medial brown stripe on the frons.
