Steleops plenitudensis n. sp.

Male. Color (in 80% alcohol). Body dark brown yellowish. Compound eyes green yellowish, on a black background; ocellar field cream-yellowish, the two upper ocelli hyaline, with thick centripetal crescents, the lower one almost inconspicuous in an ochre area. Head pattern as illustrated ( Fig. 57 ): mostly creamy, vertex with dark brown areas at sides of ocellar field as illustrated. Postclypeus with pale brown, thick vertical striae. Labrum creamy with a large, central ochre spot. Antennae: Scape and pedicel dark brown, flagellomeres brown, with both ends white, f1 with a white area mesally; maxillary palpomeres: 1 brown ochre, 2−4 creamy white, with proximal end brown ochre, Mx4 with apical area brown ochre. Coxae proximally creamy white, with reddish brown spots, rest of the coxae dark brown; trochanters dark brown, femur proximally dark brown, with brown spots on a creamy ground; tibiae creamy, with distal, small, brown spots, tarsi pale brown. Tergal lobe of mesothorax brown, on a creamy ground; tergal lobes of metathorax dark brown. Fore wing pattern as illustrated ( Fig. 55 ): a transverse brown band from anterior end of pterostigma to wing margin, anterior to Cu2-A, with hyaline lacunae on both sides of Cu2; a row of small lacunae on both sides of R; pterostigma almost totally pigmented, with a peripheral row of small yellowish-hyaline areas; cells R 1, R 2+3, R 4+5, M1, M2, M3, areola postica, and M almost totally hyaline. Hind wings pale brown, veins brown. Abdomen creamy, with brown spots, ventrally less pigmented; terminal abdominal segments, clunium, epiproct, paraproct and hypandrium reddish brown, epiproct, and paraprocts with posterior bor- der yellowish.

Morphology. Head slightly concave at vertex, short, trapeziform, MxW/MnW: 1.50, H/MxW: 1.0, compound eyes slightly elongate, little pedunculate ( Fig. 57 ), C: 75 microns; antennae about as long as the hind wings, with abundant long setae. Fore wings ( Fig. 55 ) 2.35 times as long as wide; pterostigma wider posteriorly, lp/wp: 2.4. Rs- M fused; Rs slightly curved and shorter than R 2+3, cell M pentagonal; areola postica trapeziform, elongate; vein A with large flap. Hind wing Rs-M fused, R 4+5 1.3 times as long as Rs.

Hypandrium ( Fig. 60 ) symmetric, wide anteriorly, central body with a slender, curved band directed posteriorly. Phallosome ( Fig. 58 ) rhomboid, with two distinct posterior processes, one short, stout, distally rounded, the other long, broad, with sides almost parallel, with posterior border concave. Clunium extended posteriorly over the area of the paraprocts-epiproct; paraprocts ( Fig. 59 ) elongate, with stout, acuminate process, sensory fields with 32−34 trichobothria in basal rosettes. Epiproct ( Fig. 56, 59 ) broad, anteriorly rounded, extended posteriorly to form a widely rounded projection.

Female. Color. Essentially as in males. Head pattern ( Fig. 62 ) as in males. Fore wing ( Fig. 61 ), with extensive hyaline lacunae on the pigmented areas, and small yellowish spots on the hyaline areas as illustrated. Hind wing ( Fig. 61 ) pale brown as in males. Abdomen creamy, with brown spots, ventrally less pigmented; terminal abdominal segments, clunium, epiproct, paraproct and subgenital plate reddish brown, epiproct and paraprocts with posterior border yellowish.

Morphology. Head slightly concave at vertex, short, trapeziform, H/MxW: 0.9, MxW/MnW: 1.64. Compound eyes slightly elongate, little pedunculate ( Fig. 62 ), C: 110 microns. Fore wing ( Fig. 61 ): L/W: 2.41. Pterostigma wider posteriorly; Rs slightly curved and shorter than R 2+3; Rs-M fused for a short length; cell M, areola postica and A as in males. Hind wing Rs-M fused, Rs more than twice the fused length. R 4+5 as long as Rs. Subgenital plate ( Fig. 63 ) broad, setose, posterior projection short, distally rounded, with a field of setae on posterior border. Ninth sternum broad, membranous, spermapore circular, surrounded by a wide, brown area ( Fig. 64 ). Ovipositor valvulae ( Fig. 64 ): V1 slender, elongate, distally pointed; V2 broad, with a slender, sharp, distal process; V3 broad, with posterior triangular lobe; macrosetae as illustrated.

Paraprocts broadly triangular ( Fig. 65 ) with a row of setae on outer border, sensory fields with 20−21 trichobothria in basal rosettes. Epiproct ( Fig. 65 ) triangular, broad at base, apex rounded, setae as illustrated.
