Enlinia scabrida

MALE.—Length 0.8 mm; wing 0.8 mm by 0.3 mm. Face and front dark metallic green dulled with blackish-brown pollen; front slightly over twice as wide as high; face narrowed below, eyes essentially contiguous below, anterior facets enlarged. Palpus and proboscis dark. Antenna blackish, segment 3 blunt, arista half again as long as face.

Thorax dark metallic bluish, nearly obscured by blackish pollen; setae brown with pale reflections, about 5 pairs of small acrostichals; 6 or rarely 7 pairs of dorsocentrals, only hind pair rather long; scutellum hind margin evenly rounded, bristles slightly nearer middle than sides.

Legs usually brown with pale trochanters; setae mostly dark. Forecoxa with a few dark hairs anteriorly; fore- and middle femora each with a small erect slender anteroventral seta at base; middle and hind femora with a few longer anteroventrals distally; middle tibia (Figure 211) with short stiff erect black setae ventrally, these more pronounced on distal half; hind tibia with 2 or 3 minute dorsals. Foretarsus (Figure 210) with segment 1 slightly thickened, 2 very small, 3 larger than 2nd, with minute black seta ventrally, lengths of segments from base as 7-2-4-3-4; middle tarsus as 8-5-4-3-4; hind tarsus as 7-9-6-5-5.

Wing (Figure 207) rather narrowly elliptical, hind margin evenly rounded; vein 2 evenly arched, curving slightly but distinctly forward at tip; vein 3 ending just before wing tip; crossvein about half as long as last of vein 5. Knob of halter brown.

Abdomen (Figure 209) slightly longer than thorax, cylindrical, brownish or blackish, setae small and dark; sternites without auxiliary genitalia. Hypopygium small, capping tip of preabdomen, brown, with pair of very small oval setiferous brown lamellae.

FEMALE.—Similar to male but lower face nearly as wide as antennal segment 1, anterior eye facets not notably enlarged; femora and middle tibia without erect ventral setae; foretarsus plain, lengths of segments from base as 7-4-3-2-6; wing (Figure 208) generally slightly broader and laxer in relation to length, crossvein three-fifths as long as last of vein 5.
