(Figs. 29, 57, 70, 78)

Strongylophthalmyia microstyla Shatalkin 1996: 155 . Iwasa & Evenhuis 2014: 103.

Diagnosis. Similar to S. indochinensis, n. sp. on the basis of a short pointed dorsal antennal process that is less than one-half the length of the flagellomere, but can easily be distinguished from it by the entirely black head and thorax (yellowish to reddish brown laterally in S. indochinensis).

Redescription. Lengths. Ƌ: body, 2.5–2.8 mm; wing, 2.0– 2.2 mm. Male. Head: globular; frons shining black, tinge of brown at ptilinal suture; face gray; gena yellowish gray, silvery pollinose, row of short black hairs ventrally; occiput brown, yellowish brown posteroventrally; clypeus thin, brown; palpus obovate, dark brown, with row of short black hairs ventrally; proboscis black.

Antenna (Fig. 29) scape and pedicel yellow; flagellomere ovoid, yellow with brown apicolaterally, clothed with white hairs, with dorsal process as small bump; arista 1.5 times length of flagellomere, styliform, bare.

Thorax: shining dark brown, tinge of brown on postpronotum; mesonotum and scutellum sparsely clothed with short hair-like setulae; anepisternum with sparse white hairs at notopleural suture and a few white hairs along prealar suture; katepisternum with white hairs ventrally near mid coxa.

Wing: hyaline; vein R2+3 nearly straight, ending in costa just before level of crossvein dm-cu; crossvein r-m at basal one-fourth of cell dm; veins R4+5 and M1+2 slightly converging distally; crossvein dm-cu sloping toward CuA1; last section of CuA1 to wing margin shorter than dm-cu; halter white.

WIP (Fig. 57). Generally brassy green colored throughout, with band of purple along R1 to costa; distally a mixture of blue and brassy color; anal lobe with spot of blue subbasally, surrounded by smudge of magenta.

Legs: coxae brown; fore coxa with 2 long yellowish hairs; fore femur (Fig. 70) yellowish, dorsally with 9–10 short black thorn-like spicules in two rows, ventrally with single large subbasal black thorn-like seta; mid femur dark brown, yellow only apically; hind femur dark brown; tibiae and tarsi yellow; hind basitarsus (Fig. 78) with row of translucent scale-like setae on mesal surface.

Abdomen: tergites I–II yellowish to tan; tergites III–VI dark brown, with short sparse brown hairs, these hairs longest on tergites V–VI; sternites brown.

Male genitalia. Not dissected; epandrium and surstylus shining dark brown, with white hairs; cerci dark brown, narrow basally, flared and rounded apically, with long white hairs dorsally, shorter black hairs apically and ventrally.

Female. Unknown.
