MALE.—Length 0.90–1.00 mm. Head width (paratype, on slide) 0.31 mm. Frons brownish, grayish pruinose, opaque, broader than long laterally (3:2), width 0.19 mm, pubescent, with a fine median line. Lower su rudimental, hair-like; upper not quite one-fourth of frontal width apart (4:14). Antials on level of upper su, slightly farther from them than from eye and from anterolaterals, the latter a little higher. Second row feebly convex, the bristles equidistant. Upper and lower postocular long. No bristle on jowls; cheeks with a series of 5 hairs. Third antennal joint yellow or brownish yellow, globose, width 0.065 mm; arista 0.20 mm, distinctly pubescent. Palpi yellow, of normal size, slightly angulate on upper border near base, with 5 long bristles on apical half. Proboscis small.

Thorax subshining, yellow to brownish yellow. Pubescence short, not noticeably longer behind. Mesopleura bare. Scutellum with 2 bristles and 2 very minute hairs.

Abdomen opaque, venter yellow, tergites dark brown, subequal in length, 6th yellow on anterior half. Pubescence scarce, mostly short, some longer hairs on hind margin on 6th tergite. Hypopygium of medium size, dark brown, dull, with longish hairs. Anal segment of medium length, yellow, with long hairs, end-hairs not differentiated.

Legs entirely yellow. Foretibia (in paratype) 0.19 mm; foretarsus 0.28 mm, metatarsus about as long as 2 + 3. Midtibia 0.26 mm; seam reaching apical third; cilia fine; end-spur three-fourths of metatarsus; last joint of midtarsus (Figure 96) a little thickened, about twice as long as preceding. Hind femur 3 times as long as broad, on ventral edge near base with about 4 longish curved hairs. Hind tibia 0.32 mm with 10 very fine cilia; last joint of hind tarsus slightly longer than preceding.

Wing (Figure 95) slightly grayish yellow, veins brown (yellow in paratype on slide). Length 1.04 mm in holotype, 0.85 mm in mounted paratype, width of latter 0.39 mm. Costa 0.5 of wing length, ratio of segments 14:10:5. Cilia short (0.05 mm), widely placed, there are 6 pairs between r1 and apex of costa. Mediastinalis weak. Fork large, anterior arm steep, posterior arm curved. Third vein without a bristle at base; 4th starting behind fork, evenly arcuate; 5th and 6th sinuous. Anal margin broadly convex. Axillary margin with 2 hairs. Halteres dark brown.

FEMALE.—Length 1.3 mm. Similar to male. Tergites 2–6 subequal, gradually narrowed, scarcely pubescent, hairs on hind margin of 6th not noticeably longer; 8th segment dark. Tarsi of normal length. Wing length 1.17 mm.

MATERIAL EXAMINED.—Holotype male (pinned, USNM 70266), Dominica, Fond Figues River, 20 Jan. 1965 (W. W. Wirth); allotype female (on slide, USNM), and 2 males paratypes: one pinned (USNM), another on slide (CTB), Fond Figues River, 3 Feb. 1965 (Wirth).
