Diagnosis. This new species is similar to S. laosensis, n. sp. and S. microstyla in possessing a short pointed process on the flagellomere. It can be easily separated from S. laosensis by the dorsal process being much shorter than half the width of the flagellomere (length subequal to half the flagellomere width in S. laosensis) and from S. microstyla by the head and thorax being yellowish to reddish laterally, not black.
Description. Lengths. Ƌ: body, 3.4–4.1 mm; wing, 2.8–3.0 mm. Male. Head: globular, frons shining brown, yellow below ocellar tubercle to ptilinal suture; face yellowish white; gena yellowish white, silvery pollinose, row of short black hairs ventrally; occiput brown, reddish brown posteroventrally; clypeus small, squarish, brown; palpus linear-lanceolate, dark brown, with stiff black hairs apically; proboscis black.
Antenna (Fig. 24) scape and pedicel brown; flagellomere ellipsoid, longer than wide, yellow with brown apicolaterally, clothed with white hairs, with short pointed dorsal process clothed with white hairs, length subequal to length of pedicel; arista two times length of flagellomere, styliform, bare.
Thorax: shining yellowish brown dorsally, reddish brown laterally; mesonotum sparsely clothed with short hair-like setulae; anepisternum bare medially, with sparse white hairs along notopleural suture, a few minute white hairs along prealar suture.
Wing: hyaline; vein R2+3 nearly straight, ending in costa before level of crossvein dm-cu; crossvein r-m at basal one-fifth of cell dm; veins R4+5 and M1+2 parallel distally; halter white.
Legs: coxae yellowish brown, remainder of leg yellowish; fore coxa with 3 yellowish white hairs; fore femur (Fig. 66) dorsally with black thorn-like spicules in two rows (4 longer subbasally; 4 shorter medially), ventrally with subbasal cluster of yellow hairs appearing as multiple strong thorns, long stiff yellow hairs basolaterally and ventrally.
Abdomen: segments I–II brown; segments III–VI black, with short sparse brown hairs dorsally and laterally, these hairs longest on tergites V–VI.
Male genitalia. Not dissected; epandrium and surstylus shining dark brown, with white hairs; cerci light brow, narrow basally, flared and rounded apically, with long white hairs dorsally, shorter black hairs apically and ventrally.
Female. Unknown.
