D i a g n o s i s. This species can be recognized by the combination of wing uniformly pale gray, two pairs of scutellar setae, frontal vitta yellow, and female mid femur without femoral organ, brown setulose anteriorly.

D e s c r i p t i o n. Head (fig. 4, 2–4) yellow, frontal vitta yellow, usually with brownish spots on vertical plates, c. 1.2–1.4 times as long as wide in posterior half; parafacial twice as wide as flagellomere 1; eye 1.8–2 times as high as wide, 1.1–1.3 times as wide as parafacial and 2.8 times as high as gena. Face entirely yellow or with pair of brown spots ventrally; concave, with faint medial suture, but without carina. Gena usually with brown spot on subocular sclerite. Occiput entirely yellow. First flagellomere entirely reddish yellow, 2.8 times as long as wide, 1.4 times as long as pedicel and 2.3 times as long as scape. Arista entirely reddish yellow, 2-segmented. Scape 1.5 times as long as wide. Palp yellow, cigar-like, 4–4.5 times as long as wide, and as long as first flagellomere. Labellum very large, almost as long as eye height. Lateral vertical setae (vte) indistinguishable from postoculars or absent; medial vertical setae (vti) slightly shorter than pedicel and 0.9–1.1 times as long as postocellar, ocellar and orbital setae and 1.5–2 times as long as mesofrontal setulae (above lunule).

Thorax yellow to brownish yellow, without dark pattern. Prosternum saddle-like, short setulose. Postpronotal lobe with 8–10 setulae and one long seta; proepisternum with 3–6 setae. Scutum 1.1 times as long as wide, subshining yellow with faint brown areas, sparsely reddish-brown to brownish-yellow setulose, with white microtrichia not obscuring underlying cuticle; 2 notopleural, 1 supra-alar, 1 intra-alar, 1 postalar, 2–3 postsutural dorsocentral, and 0 acrostichal setae. Scutellum yellow, whitish microtrichose, with two pairs of setae as long as scutellum, but without setulae (fig. 4, 5). Anepisternum yellow, with dark yellow or brownish anterior part; posterior part with 2–3 long setae and 7–9 irregular long setulae; anepimeron with 2 long setae and 4–6 irregular long setae; katepisternum with 1–2 long setae and 2–3 thinner and slightly shorter setulae posterodorsally. Katatergite, anatergite and mediotergite brownish yellow, subshining, sparsely whitish microtrichose.

Wing (fig. 4, 6; 5, 3) entirely hyaline or pale yellowish along anterior margin, covered with greyish microtrichia. Vein R 4+5 bare. Wing length 13.0– 14.5 mm. Lower calypter narrow, without cilia; upper calypter with short black fringe basally and 7–8 black cilia half as long as calypter width. Halter creamy white.

Legs (fig. 4, 1; 5, 7) entirely yellow, black setulose and setose. Coxae moderately long, sparsely setose and setulose, unmodified. Fore femur moderately narrow, with 3–4 long setae on posterior surface. Mid femur (fig. 4, 7) without femoral organ, uniformly dark brown setulose on anterior surface. Hind femur narrow, short setulose without long setae (except basiventral seta).

Abdomen narrow, cylindrical, almost twice as long as thorax, with syntergite 1+2 long, 1.1 times as long as tergites 3–6 combined. Synsternite 1+2 long Y-shaped (fig. 9, 2). Sternites 3–6 subquadrate, with 2–3 black setae and 7–9 setulae at posterolateral corners.

Female genitalia. Oviscape entirely orange, short and sparsely black setulose, uncompressed, almost as high as wide and as long as tergites 3–6 combined, with apex short and slightly bent ventrally, bearing neither hooks, nor long setulae (4, 8, 9). Eversible membrane without sclerotized lobes or raspers. Aculeus moderately wide (fig. 4, 10) Spermathecae sausage-like, poorly sclerotized (fig. 4, 11).

Male as in fig. 5. Epandrium similar to that in Eupyrgota (fig. 5, 5).
