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 View FIGURES 26 – 33 ) 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 View FIGURES 54 – 61 ). 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 View FIGURES 70 – 77 ) 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 View FIGURES 78 – 81 ) 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.
