Steleops mendivili n. sp.

Male. Color (in 80% alcohol). Head with genae creamy white; compound eyes black, ocelli hyaline, surrounded by a thick, ochre rim, the lower one separated from the two upper ones by thin, creamy, convergent lines. Head with dark brown pattern as illustrated ( Fig. 46 ): two dark brown, diagonal bands from each compound eye, directed towards epistomal sulcus, forming a V, continuing to postclypeus and labrum; a creamy white area between the bands from the compound eyes and in vertex. Postclypeus with ochre, almost vertical striae. Genae creamy white. Antennae: Scape and pedicel cream, pedicel with small, apical, dark brown band; flagellum creamy white; maxillary palpomeres creamy white, Mx4 distally pale brown. Prothorax creamy white, meso- and metathorax dark brown, with some small creamy areas; prothoracic coxae and trochanter creamy white, prothoracic femur, tibia and tarsi pale brown, femur with a dark ring medially; meso and metathoracic coxae dark brown, with apex creamy white; meso- and metathoracic trochanter, femur, tibia and t1 creamy, distally brown, t2 brown; meso- and metathoracic femora with dark brown ring medially. Tergal lobes of meso- and metathorax dark brown. Abdomen creamy white, with irregular dark, subcuticular rings, less pigmented ventrally; genital segments dark brown; epiproct and paraprocts yellowish cream. Fore wings and hind wings hyaline, veins brown.

Morphology. Head deeply concave at vertex, compound eyes elongate, pedunculate ( Fig. 46 ), sides almost parallel in front view, MxW/MnW: 1.42, H/MxW: 1.20; C: 425 microns. Fore wings ( Fig. 44 ): L/W: 2.85; pterostigma widest in the middle, Rs-M joined by a short crossvein; Rs curved and shorter than R 2+3-R 4+5; cell M almost rectangular; areola postica trapeziform. Hind wing Rs-M fused, Rs about four times the length of the fused length; R 4+5 about three times as long as Rs. Hypandrium symmetric ( Fig. 49 ); central strap strongly sclerotized, curved posteriorly ( Fig. 45 ), with a row of denticles along the sides; two basal, short, acuminate projections. Phallosome broadly pentagonal ( Fig. 48 ). Clunium with two long, strongly sclerotized projections, with small denticles, distally rounded, curved inwards ( Figs. 45, 47 ).

Paraprocts ( Fig. 47 ) round, setose, sensory fields with 20−22 trichobothria in basal rosettes; mesal prong short, slender, acuminate. Epiproct ( Fig. 47 ) broad, scutiform, concave laterally, with antero-lateral corners round, slightly protruding.

Female. Color (in 80% alcohol). Body creamy white, with dark areas as indicated below. Compound eyes black, ocelli hyaline, as in the male. Head pattern as illustrated ( Fig. 52 ): two ochre bands from each compound eye, directed towards epistomal sulcus, meeting a slender ochre band radiating on each side of ocellar group, then continuing to epistomal sulcus; a cream area between the bands from the compound eyes, and a large pigmented area between ocellar group and epistomal sulcus, as illustrated. Postclypeus with ochre diagonal striae. Antennae: Scape pale brown, pedicel and flagellum creamy white; maxillary palpomeres 1−3 white, Mx4 pale brown. Prothoracic coxae pale brown; meso- and metathoracic coxae dark brown. Tergal lobes of meso- and metathorax dark brown. Abdomen creamy, with well defined subcuticular dark rings. Fore wings ( Fig. 50 ) almost hyaline, Sc brown, R1 creamy-yellowish, bordering the pterostigma, nodus brown. M+CuA, CuA, Cu 1b, proximal part of Cu 1a, distal part of R 2+3 and basal part of M2 y M3 yellowish green; other veins brown. Brown spots on Rs, M and near nodulus (junction CuP-A), as illustrated. Hind wings hyaline, veins Rs, M, and CuA brown.

Morphology. Head deeply concave at vertex, sides almost parallel, compound eyes oval, pedunculate ( Fig. 52 ), H/MxW: 1.25; MxW/MnW: 1.30, C: 380 microns.

Fore wings ( Fig. 50 ): L/W: 2.97; pterostigma as in the males, lp/wp: 3.46; Rs-M joined by a short crossvein; Rs curved and shorter than R 2+3; cell M almost rectangular; areola postica trapeziform. Hind wing as in the males; vein R 4+5 almost 3 times as long as Rs. Subgenital plate ( Fig. 54 ) broad, triangular, setose, with posterior projection short, rounded, distally narrow and with two pairs of macrosetae and one pair of short setae: apex with a field of fine setae. Ninth sternum broad, membranous; spermapore circular, surrounded by a little pigmented, elongate area, spermapore sclerite broad, triangular ( Fig. 51 ). Gonapophyses ( Fig. 51 ): V1 long, slender, distally pointed, with a field of spines distally on inner margin; V2 almost as long as V1, stout, distally rounded, with scattered microsetae; V3 trianguliform, as long as V2, setose as illustrated. Paraprocts ( Fig. 53 ) broadly triangular, with apex rounded, with macrosetae in outer margin; sensory fields with 24 trichobothria issuing from basal rosettes. Epiproct ( Fig. 53 ), basally wide, almost trapeziform; posterior border widely rounded, with field of setae mesally, and a row of setae along postero-lateral border.
