Enlinia maculata

MALE.—Length 0.9 mm; wing 1.1 mm by 0.5 mm. Face and front dark metallic green with only slight pollen; eyes essentially contiguous below, anterior facets enlarged. Palpus and proboscis dark. Antenna black, segment 3 blunt, arista nearly twice as long as face.

Thorax metallic dark green with slight yellowish pollen, more grayish pollen on pleura; setae dark with pale reflections; 7 pairs of acrostichals, 7 or 8 pairs of small dorsocentrals; scutellum hind margin evenly rounded, bristles widely separated.

Legs brown with fore- and middle trochanters pale; setae mostly dark. Forecoxa with a strong seta on inner anterior surface, a few small pale setae at base; forefemur rather slender, with series of longer posteroventrals distally; middle femur (Figure 26) rather broad, lower margin more strongly curved near base and there bearing a crest of a few stout setae, the longest as long as femur width; hind femur rather broad, with somewhat longer stouter setae ventrally especially toward tip; foretibia somewhat stout; middle tibia slightly flattened below with dense short erect pubescence near tip; hind tibia with 3 small dorsals, basal, subbasal, and apical. Foretarsus (Figure 27) segments 1 and 2 somewhat angular with a few stout setae, segments 3 and 4 with prominent lobes, that on segment 4 broader, last segment long and narrow; lengths of segments of middle tarsus from base as 7-5-5-4-5; hind tarsus as 12-9-7-6-6.

Wing (Figure 29) oval with slightly sinuous hind margin bearing fringe of long hairs, slight sinus at tip of vein 5 followed by slight bulge, a small dark spot lying against anterior side of vein 4 in middle of last part, wing otherwise slightly brownish gray; veins 2, 3, and 4 diverging in basal part, bending near midwing just before crossvein and running nearly parallel to margin; vein 5 close to 4 and with matching bend, somewhat diverging beyond the short oblique crossvein, crossvein one-third the length of last part of vein 5; vein 6 represented by narrowly darkened anal margin and dark intramarginal streak. Knob of halter black.

Abdomen (Figure 28) as long as thorax, blackish with metallic dark green reflections, stout, cylindrical, straight, setae dark; sternite 3 with small median projection near hind margin, sternite 4 with median crest of small setae near front margin, sternite 4 followed by cleft sclerites on each side bearing downward projecting lobe. Hypopygium brown, medium size, capping tip of preabdomen, bearing a pair of small dark setiferous lobes, other appendages with only projecting setae visible.
