Enlinia interrupta

MALE.—Length 1.0 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 greatly enlarged. Palpus and proboscis dark. Antenna black, segment 3 blunt, arista near half again as long as face.

Thorax metallic dark green with slight grayish pollen; setae dark with pale reflections; about 8 pairs of small acrostichals, 8 or 9 pairs of dorsocentrals; scutellum hind margin evenly curved, bristles as near sides as middle.

Legs mostly brown with paler trochanters; setae mostly dark. Forecoxa (Figure 40) with 2 strong setae on the anterior surface, a few pale hairs distally; forefemur (Figure 40) broad, more so toward the base, with a small erect ventral seta at the broadest part followed by a series of small and not very distinctive setae; middle femur broad, especially toward the base, lower margin somewhat angular near base, a long stout bristle borne on tubercle at angle followed by 3 or 4 progressively shorter setae on smaller tubercles; hind femur rather broad, with a few longer setae anteroventrally near tip; foretibia (Figure 40) becoming wider toward tip; middle tibia rather broad, flattened ventrally in distal half with rather crowded short erect hairs; hind tibia with indistinct but slightly longer dorsal seta near base and tip. Foretarsus (Figure 40) modified with very stout seta on tip of thickened segment 1, segment 3 with an acute projection on tip ventrally, a short stout apical seta partly surrounded by a pubescent lobe of segment 4; lengths of segments of middle tarsus from base as 6-3-3-2-3; hind tarsus as 8-6-5-4-4.

Wing (Figure 41) rather oblong with anal margin considerably rounded in the middle, a shallow lobe near tip of vein 5, wing clear with brown veins; vein 2 rather sinuous, diverging from 3rd at tip; veins 3 and 4 nearly straight, diverging from near base; vein 5 ending short of wing margin, continued in streak of pigment nearly reaching margin, last part of vein slightly shorter than the perpendicular crossvein; vein 6 fused with anal margin, which is darkened, thickened, and bearing progressively longer setae in a series that ceases abruptly at the end of the thickened part of the margin. Knob of halter dark.

Abdomen (Figure 42) about as long as thorax, stout, cylindrical, curving downward, blackish with metallic bluish-green reflections, setae dark; middle of sternite 3 raised into a point, sternite 4 with short forked appendage lying forward against point of 3rd. Hypopygium brown, large, capping tip of preabdomen, projecting forward below, bearing rather small dark lamellae that bear short dark hairs; tip of hypopygium bearing a slender black median projection and a pair of very delicate long-attenuate almost transparent to slightly brownish appendages.

FEMALE.—Not seen.
