description: Strongylophthalmyia borneensis Evenhuis, n. sp.
(Figs. 1, 11, 18, 46, 47, 63, 90)
Diagnosis. This new species is similar to S. punctata and S. lowi, n. sp. but can be differentiated from each based on the infuscation of the wing (wing hyaline in S. punctata and S. lowi) and the dark brown mid and hind femora with only the basal fifth yellow (basal third yellow in S. punctata and apex yellow in S. lowi).
Description. Lengths. Ƌ: body, 4.3–6.2 mm; wing, 3.8–5.5 mm. Male. Head (cf. Fig. 1): globular, shining black; face gray; gena dull dark grayish brown, row of short yellow hairs ventrally; clypeus small, subrhomboid; palpus (Fig. 11) boat-shaped, dark brown, with black hairs ventrally and apically; proboscis black.
Antenna (Fig. 18) scape and pedicel dark brown; flagellomere subrhomboid, rounded apically, longer than wide, yellowish brown with apicolateral region dark brown, densely clothed with white hairs, with long, slender, Sshaped dorsal process 1.75 times length of flagellomere; arista slightly shorter than dorsal process, styliform, bare.
Thorax: shining black throughout, mesonotum and scutellum sparsely clothed with short white hair-like setulae; anepisternum with tuft of black hairs medially, a few minute white hairs along prealar suture; katepisternum with long white hairs ventrally near mid coxa.
Wing (Fig. 47) hyaline, tinge of brown at extreme apex; vein R2+3 nearly straight, ending in costa well beyond level of crossvein dm-cu; crossvein r-m before middle of cell dm; veins R4+5 and M1+2 parallel distally; crossvein dm-cu not perpendicular to CuA1; last section of CuA1 to wing margin subequal in length to crossvein dm-cu; halter white.
WIP (Fig. 46). Distally a mixture of green and lavender color; magenta-colored in basal half of radial and medial portions; anal lobe with alternating bands of magenta and brassy green; darker coloration corresponding to faint infuscation at apex and medially.
Legs: coxae, fore femora, and tibiae dark brown, tarsi yellow; fore coxa with 3 long black hairs; fore femur (Fig. 63) dorsally with 4–5 short black thorn-like spicules in single row; mid and hind femora yellow on basal fifth, remainder dark brown.
Abdomen: tergites I–II brown; tergites III–VI black, with short sparse brown hairs, these hairs longest on tergites V–VI; sternites brown.
Male genitalia (Fig. 90); epandrium and surstylus shining black, with white hairs; cerci dark brown, narrow basally, flared and rounded apically, with long white hairs dorsally, shorter black hairs apically and ventrally; phallapodeme subequal in length to distiphallus; anterior lobe of hypandrium bifid; distiphallus roughly two times length of epandrial complex, with sclerotized globular apex.
Female. Flagellomere without long dorsal process; arista slender and bare, 1.5 times length of flagellomere; clypeus large, bulbous; anepimeron without lateral tuft of hairs; abdominal segments VI–X modified into a tubular ovipositor. Other characteristics same as those of male; two well-developed spherical spermathecae.
