Description

Length 4–5 mm; wing length 3.7–4.0 mm; mesonotum length 1.60–1.75 mm. Most setae yellowish to golden orange, often with base brownish.

Head: Mostly yellow to orange, sometimes with large dark brown area laterally on occiput. Genal height 0.15–0.17 times long diameter of eye. Eye 0.78–0.81 times as long as high (shortest vs. longest diameter). Face concave, flat medially or with very narrow, weak carina. Frons moderately broad, 1.1–1.5 times as broad as eye in dorsal view, nonsetulose medially except for 1 setula slightly anteromedial to anterior orbital seta; 3 frontal and 2 orbital setae yellowish, acuminate; ocellar seta yellowish, longer than frontal setae. 1–2 genal setae and numerous genal setulae yellowish. Facial ridge with 2 rows of minute yellowish acuminate setulae. Antenna short, first flagellomere 1.3 times as long as pedicel, 1.3 times as long as wide, rounded apically; arista pale brown, sparsely minutely pubescent. Labella capitate; palpus moderately stout, slightly dorsally curved.

Thorax: Entirely moderately densely microtrichose; mostly appearing bluish gray due to underlying brown cuticle, except for yellow postpronotal lobe, lateral postsutural margin of scutum (including postsutural supra­alar and intra­alar setae), scutellum, and sometimes propleuron, notopleuron, and/or anterior part of anepisternum. Scutal setulae whitish, slightly lanceolate, nearly evenly distributed. Postpronotal lobe with several dorsal setulae and 2–3 slightly larger, lanceolate setulae laterally. Propleuron with row of 5–6 lanceolate setulae. Other pleural setulae yellowish. Scutellum very slightly convex, with setulae evenly distributed on disk or only near margin. Anepisternum setulose on dorsal margin (setulae dorsally directed) and posterior half (setulae posteriorly directed).

Legs: Yellow, except mid and hind coxae and femora sometimes partially brown, femora with with as much as basal 3/4 brown.

Abdomen: Entirely brown and entirely moderately microtrichose. Setulae brown, acuminate.

Male terminalia: Lateral surstylus simple, short, in posterior view nearly forming oval with epandrium, apex mesally curved and truncate. Glans ( Figs. 13–14 ) relatively stout, mostly sclerotized, with small simple membranous apical lobe; acrophallus relatively stout, gradually curved in dorsal view, and with basal half fused to outer sclerotized sheath laterally.

Female terminalia: Oviscape 1.25 mm long, 0.75 times as long as mesonotum, dark brown, with short, slender, brown acuminate setulae. Aculeus ( Fig. 11 ) 0.87 mm long, 0.17 mm wide, relatively slender, tip ( Fig. 12 ) dorsally curved, elongate triangular, lateral margins gradually tapering to blunt apex. Spermathecae pear­shaped.
