Enlinia anomalipennis Robinson 1969

Enlinia anomalipennis

MALE.—Length 0.8 mm; wing 1.0 mm by 0.4 mm. Face and front metallic bluish green with only slight pollen; eyes nearly or essentially contiguous below, facets rather large in lower part. Palpus and proboscis brown. Antenna black, segment 3 blunt, arista half again as long as face.

Thorax shining metallic green with slight yellowish pollen above, more grayish pollen on pleura; setae black with pale reflections; about 7 pairs of acrostichals, 7 or 8 pairs of dorsocentrals; scutellum hind margin evenly rounded, bristles as near sides as middle.

Legs brown; setae mostly yellowish brown. Forecoxa (Figure 12) with strong seta on inner anterior surface, a few long upward curved hairs anteriorly; middle femur (Figure 14) rather broad, lower margin rather angular near base, a cluster of stout setae at the angle; hind femur rather broad with a longer seta anteroventrally toward tip; fore- and middle tibiae without distinctive setae, hind tibia with a small dorsal seta near base and one near tip. Foretarsus (Figure 13) highly modified, segment 1 broad with 2 short stout setae, segment 2 short and broad with apical appendage projecting far along beside next segment, segment 3 long and slender with next segment arising near middle, segment 4 distally and segment 5 throughout somewhat broad; lengths of segments of middle tarsus from base as 11-5-4-3-5; hind tarsus as 10-7-6-5-6, distal segments all rather broad.

Wing (Figure 16) rather oval with a cuneate base, a sinuous hind margin, and a fringe of long hairs posteriorly; vein 2 nearly straight throughout; vein 3 close to and parallel with vein 2 except near tip, turned rather sharply back near tip and ending shortly before extremity of wing; vein 4 widely diverging from third, very close to and nearly parallel with vein 5, becoming sinuous beyond crossvein and ending well behind wing tip; last part of vein 5 ending before margin, about twice as long as short crossvein; sinus in hind margin opposite crossvein; vein 6 completely lacking but anal margin rather thickened and brownish. Knob of halter dark.

Abdomen (Figure 15) about as long as thorax, cylindrical to somewhat compressed, blackish with bluish reflections, seta dark; middle of sternite 3 slightly projecting and bearing a few short but distinct black setae. Hypopygium capping tip of preabdomen and projecting slightly forward below, brown with lighter brown lamellate tips, outer appendages apparently reduced to slender pinnately haired projections.

FEMALE.—Face about as wide below as antennal segment 1, anterior eye facets not much enlarged. Forecoxa and tarsus, and middle femur plain; lengths of segments of foretarsus from base as 6-3-2-2-5. Wing (Figure 17) plain with longitudinal veins all rather slightly and evenly diverging from near base, vein 2 bulging rather prominently inward from costa in distal one-half, last of vein 5 reaching hind margin, about twice as long as crossvein.

TYPE-DATA.—Holotype ♂ from Mexico: San Luis Potosi, small ravine a few miles south of Tamazunchale, from partially shaded moist rock surface, 13 August 1962, H. Robinson (USNM 70283). Allotype ♀ from Hidalgo, just north of Chapulhuacan, on rock face moist from seepage, above a roadside spring, 13 August 1962. Paratypes: same locality as holotype, 13–14 August 1962, 2 ♂; 10 May 1963, 5 ♂; same locality as allotype, 5 and 13 August 1962, 5 ♂; 10 and 30 May 1963, 7 ♂ and 3 ♀; Guerrero, near Tierra Colorada, around rocks by partially shaded stream, 29 May 1963, 3 ♂ and 6 ♀; all collected by H. Robinson.
