Treatment

Strongylophthalmyia nigripalpis Evenhuis , n. sp. ( Figs. 15 View FIGURES 10 – 17 , 31 View FIGURES 26 – 33 , 40 View FIGURES 38 – 41 , 71 View FIGURES 70 – 77 )

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 View FIGURES 10 – 17 ) black, linear-ovate, with yellowish white pubescence and scattered black hairs; proboscis yellowish brown.

Antenna ( Fig. 31 View FIGURES 26 – 33 ) 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 View FIGURES 38 – 41 ): 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 View FIGURES 70 – 77 ) 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.
