Strongylophthalmyia nigripalpis Evenhuis, n. sp. (Figs. 15, 31, 40, 71)

Diagnosis. This new species is similar to S. palpalis Papp and S. sumatrana, n. sp., by all three possessing a indistinct bump or minute dorsal antennal process, but it can be distinguished from them by the brown mesonotum (mesonotum yellow to reddish brown in S. palpalis and S. sumatrana) and the large obovate black male palpus (palpus smaller and differently shaped in S. palpalis and S. sumatrana).

Description. Lengths. Ƌ: body, 3.4–3.8 mm; wing, 3.0– 3.4 mm. Male. Head: globular; frons shining black, yellowish brown above ptilinal suture; face yellow; gena yellow, silvery white pollinose, row of short white hairs ventrally; occiput dark brown, yellowish brown posteroventrally; clypeus small, squarish, yellowish brown; palpus (Fig. 15) black, linear-ovate, with yellowish white pubescence and scattered black hairs; proboscis yellowish brown.

Antenna (Fig. 31) scape and pedicel yellow; flagellomere ovoid, yellow with yellowish brown apicolaterally, clothed with white hairs, with short, pointed dorsal process distal to base of arista; arista 2.2 times length of flagellomere, styliform, bare; Thorax (Fig. 40): shining brown; mesonotum and scutellum sparsely clothed with short hair-like setulae; propleuron yellow, remaining pleura brown; anepisternum with a few minute white hairs along prealar suture; katepisternum with white hairs ventrally near mid coxa.

Wing: hyaline; vein R2+3 nearly straight, ending in costa 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 perpendicular to CuA1; last section of CuA1 to wing margin shorter than dm-cu; halter white.

Legs: yellowish white; fore coxa with 2 long yellowish white hairs; fore femur (Fig. 71) dorsally with 4 short black thorn-like spicules in two groups, plus 3 longer subbasally; 8 minute medially and subapically; remainder of leg segments unmodified.

Abdomen: tergites I–II yellowish brown, weakly sclerotized medially; tergites III–VI brown, with short sparse brown hairs, these hairs longest on tergites V–VI; sternites brown.

Male genitalia. Not dissected; epandrium and surstylus shining brown, with admixed brown and white hairs; cerci light brown, narrow basally, flared and rounded apically, with 2 long black hairs medially, shorter yellow hairs apically and ventrally.

Female. Unknown.
