Diagnosis. This new species is easily distinguished from its congeners in this subgroup by the distinctive racquetshaped male palpus (Fig. 13) and the white posterolateral spot on the lower portion of the occiput.
Description. Lengths. Ƌ: body, 3.0 mm; wing, 2.8 mm. Male. Head: globular, frons shining brown, yellow above antennae; face yellow; gena yellow, silvery pollinose, row of short black white ventrally; occiput brown, brown posteroventrally with white posterolateral spot; clypeus thin, yellowish brown; palpus (Fig. 13) with long thin, yellow stem-like base and black clubbed apex making it appear racquet-shaped, without apparent vestiture; proboscis brown.
Antenna (Fig. 21) yellow; flagellomere subovoid, clothed with white hairs, with long, slender, curved brown dorsal process, densely clothed with decumbent white hairs, four times length of flagellomere; arista one-half length of dorsal process, styliform, bare.
Thorax: shining; mesonotum and scutellum shining yellowish brown, minute brownish setulae in rows along slightly darker medial, paired dorsocentral and postalar stripes; pleura brown above, yellow below; anepisternum bare; katepisternum with white hairs ventrally near mid coxa.
Wing: hyaline; vein R2+3 nearly straight, ending in costa just beyond level of crossvein dm-cu; crossvein dm-cu almost perpendicular to CuA1; last section of CuA1 one-half length of dm-cu; crossvein r-m at middle of cell dm; veins R4+5 and M1+2 slightly converging distally; halter white.
Legs: yellow; fore coxa with 2 long yellowish white hairs; fore femur dorsally with 6 short black thorn-like spicules, ventrally with subbasal cluster of yellowish orange hairs appearing thorn-like; hind femur with minute knob-like protuberance basomesally; otherwise remainder of legs unmodified.
Abdomen: tergites I–II yellowish to tan, weakly sclerotized medially and laterally; tergites III–V brown laterally, yellowish brown medially, tergite VI brown, with short sparse brown hairs, these hairs longest laterally; sternites pale brown, weakly sclerotized medially.
Male genitalia. Not dissected; epandrium and surstylus shining brown, with white hairs; cerci white, narrow basally, flared and rounded apically, with long white hairs dorsally, shorter brown hairs apically and ventrally.
