Soita ophioneum ( Enderlein), 1920 , new combination

( Figs.135–142 )

Xaniosternum ophioneum Enderlein, 1920: 336 . Type Locality: Equatorial Guinea. Nkolentangan (HT ♂ ZMHB).

Diagnosis. Head entirely yellow except brown ocellar tubercle, lacking dark spots on occiput, frons and face. Thorax entirely yellow to yellow-brown, scutellum with 1 pair of setae, katepisternum with 3 rows of short brown spines extending longitudinally along anteroventral margin. Wing uniformly yellow, without dark markings. All body seta yellow to brown except for 1 pair of strong orbital seta dark brown. Abdomen yellow-brown with some vague dark brown markings.

Description. Male: body length 13.0 mm, wing length 9.8 mm.

Head ( Figs. 135–136 ): entirely yellow except ocellar tubercle brown, lacking dark spots on occiput, frons and face. Head wider than high, frons sloping, antenna situated at middle of head. Occiput distinctly swollen. Frons parallel-sided, margins not convergent anteriorly. One pair of strong dark brown orbital setae and 2 pairs weak and yellow-brown 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 to posterior margin of lunule. Vertical setae present (setae themselves lost, but sockets obvious), ocellar seta absent, genal seta present.

Thorax (Figs. 135,140). Entirely yellow to yellow-brown. Transverse suture complete. Metathoracic, postcoxal bridge heavily sclerotized. Scutum almost parallel-sided, about 3 times as long as wide. Scutellum very short, less than half as long as wide, with 1 pair of setae. katepisternum with 3 rows of short brown spines extending longitudinally along anteroventral margin. Thoracic chaetotaxy: 2 pairs scapular, 1 dorsocentral, 1 scutellar, 1 postprontal, 2 notopleural, 1 postsutural supra-alar, 1 postalar, 1 intra-alar, 2 anepisternal, 1 anepimeral, 1 katepisternal setae present and dark brown; prescutellar acrostichal seta present.

Wing ( Figs. 141–142 ). Uniformly yellow, without dark markings. Pterostigma yellow-brown and about half as long as cell c. Vein R4+5 densely setulose dorsally almost from base to apex. Vein Cu1 setulose dorsally from base to slightly proximal to crossvein R-M. Legs. Uniformly yellow, mid tibia with 2 large black apicoventral spurs (one is broken).

Abdomem ( Fig. 138 ). Yellow-brown with some vague dark brown markings. Syntergite 1+2 with pair of outstanding submedial posterior setae, tergite 5 with large posterior setae (several missing, but large sockets present). Tergites 3 and 5 about same length, tergite 4 slightly longer than tergite 3 and 5.

Female: Unknown.

Distribution: Equatorial Guinea.

Specimen examined: EQUATORIAL GUINEA: Nkolentangan, Novermber 1907 to May 1908, S.G.Tessmann, ♂ Holotype (ZMHB).

Remarks. This species resembles S. ensifera and S. cylindrica in having the katepisternum with short spines extending longitudinally along the anteroventral margin, but it differs from them by having only 1 pair of scutellar setae, anepisternum without short spines, and wing uniformly yellow.
