Diagnosis. This species differs from other Blepharoneura species by the following combination of characters: scutum with 2 pairs of brown vittae; anepisternum entirely yellow; hind femur brown on apical fourth; cells r2+3, r4+5 and m each with 2 marginal or submarginal hyaline marks, those in r2+3 and r4+5 small; and aculeus tip with 7 lobes, including unpaired medial lobe, 2 pairs of step-like lobes, and broad, digitiform pair of lateral lobes.

Description. Head: Dark brown area on ocellar tubercle extended to or almost to level of postocellar seta. Medial occipital sclerite with pair of brown submedial vittae on ventral half. Occipital suture narrowly brown.

Thorax: Scutum entirely microtrichose, with 2 pairs of dark brown vittae; submedial vitta broadly interrupted posterior to transverse suture and not connected to mark on posterior margin; sublateral vitta sometimes (holotype) absent posterior to transverse suture, when present separated from mark on posterior margin; posterior margin with 2 well separated brown marks. Notopleuron entirely yellow. Small brown spots anterior to postsutural supra-alar seta and anterior to postalar seta absent. Small brown spot lateral to dorsolateral corner of scutellum present. Scutellum with pair of small submedial brown spots (faint in paratype). Subscutellum with pair of dark brown spots on dorsolateral half, isolated from pair of narrow brown vittae on mediotergite. Pleuron entirely yellow or with small brown medial spot on anepimeron (paratype). Basalare with brown spot. Dorsocentral seta aligned slightly anterior to postalar seta or almost midway between postalar and postsutural supra-alar seta.

Legs: Mostly yellow. Mid femur sometimes with diffuse elongate anteroventral and posteroventral brown marks. Hind femur brown on apical 1/4 but not extending to apex dorsally.

Wing ( Figs. 5 , 77 ): Length 7.04–7.30 mm, width 3.68–3.80 mm, ratio 1.91–1.92. Crossvein r-m at 0.55– 0.56 distance from bm-cu to dm-cu. Cell c with 2 rectangular to inverted trapezoidal hyaline spots, both reaching costa and subcosta; medial brown area paler than area of cell r1 posterior to pterostigma, fainter medially, and as broad as to slightly narrower than hyaline spots. Pterostigma entirely brown or (1 wing of holotype) with very small yellowish subapical spot. Cells r1 and r2+3 basally (proximal to apex of R1) with 1–2 small yellowish spots in r1 and 1 small yellowish or hyaline spot in r2+3. Radial cells medially with 2 narrow basal marginal hyaline marks in cell r1 separated by narrower distinct dark brown area, both reaching R2+3, basal mark [#5] quadrate; cell r2+3 with 1 moderately large hyaline spot [#8] aligned with basal mark in r1 and 1 broader spot [#9] aligned with second mark in r1, both reaching R2+3 and R4+5; cell r4+5 with hyaline spot [#14] in anterior half of cell aligned between r1 marks and with moderate sized hyaline spot [#15] aligned distal to dm-cu, sometimes (holotype) with additional posterior hyaline spot aligned with second mark in r1. Distally cell r1 with small marginal hyaline spot [#6] (holotype) or small hyaline spot [#6A] in posterior half (paratype). Cell r2+3 with 2 very small marginal hyaline spots [#10A, #11], neither extending half distance to R4+5; with small to minute hyaline spot [#10B] in posterior half aligned with proximal marginal spot, touching or isolated from R4+5; and also with 1–2 more proximal small to minute posterior hyaline or yellow spots [between dm-cu and #10B]. Cell r4+5 with small hyaline spot near or slightly posterior to midwidth aligned between hyaline marks in cell m; and with 2 small ovoid marginal or submarginal hyaline spots, anterior spot [18A] touching costa, posterior spot [#18] touching or narrowly isolated from costa; sometimes (1 wing of holotype) with additional minute hyaline spot slightly proximal to posterior spot. Cell m without subbasal hyaline spot [#49] near midlength of dm-cu; with 3 large ovoid hyaline spots, 2 marginal [#27, #29] and 1 medial spot [#26] aligned with proximal marginal spot, or (1 wing of holotype) with proximal marginal and medial spots fused to form short band; none of hyaline marks reaching vein M. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20]. Cell bcu with (1 wing of holotype) or without hyaline spot in lobe. Posteromedial part of wing with multiple large hyaline spots and markings; cell br subapically with moderately large hyaline spot [#13] and usually (except in 1 wing of paratype) with smaller slightly more proximal hyaline spot [#44], both touching vein M but not R4+5; cell dm with subbasal elongate hyaline mark across cell [fused #51, #52] or with only posterior spot [#52], posteriorly aligned with spot in cell cu1 [#31] and anteriorly aligned with spot in cell br [#44] if present, posterior spot sometimes medially connected to anterior part of more distal mark [#21]; elongate hyaline mark across cell [fused #21, #22?, #23?, #24?], broader posteriorly, anterior part aligned with subapical spot in cell br [#13], posterior part aligned with Y-shaped mark in cell cu1; cell cu1 with relatively large anterior subbasal hyaline spot [#31] aligned with subbasal mark in dm, with broad Y-shaped medial mark [fused #32, #33, #36], narrowly or distinctly separated from proximal marginal mark across vein A1+Cu2 [#34, #39], proximal branch of mark [#32] aligned slightly distal to line from proximal marginal mark [#34] to subapical spot in cell br [#13], base of Y-shaped mark [#36] moderately broad; subapical marginal hyaline mark [#37] moderate sized, not reaching Cu1. Cell dm with subapical spot [#25] hyaline and relatively large, touching or isolated from vein M; also with small to minute subapical hyaline or pale brown spot [#53] near midwidth or in posterior half aligned with or slightly proximal to subapical mark in cell cu1.

Abdomen: Syntergite 1+2 with pair of brown bands (probably fused submedial and sublateral spots) and small brown spot on posterolateral corner. Tergites 3–5 with pair of relatively small submedial dark brown spots, on tergite 5 of male connected to sublateral mark; with pair of large sublateral brown marks (forming vittae), each with narrow medial extension along posterior margin and narrow lateral extension to posterolateral corner.

Female terminalia: Oviscape entirely dark brown; length 1.30 mm. Aculeus ( Fig. 155 ) 0.95 mm long, 2.35 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip relatively short and broad (lobed part 0.32 times as long as wide), with small weakly trilobed medial lobe and 3 pairs of lobes, lateral lobe large and digitiform, with minute serrations apically, sublateral and submedial lobes acute, steplike, submedial lobe slightly smaller; medial, submedial and sublateral lobes separated by moderately deep gaps, ca. half as long as wide. Spermathecae subspherical, with nearly straight, slender sclerotized neck and small cylindrical basal apodeme.

Male terminalia (not dissected, but surstyli visible): Medial surstylus with prensisetae separated by several times width of medial prensiseta, medial prensiseta on long lobe, lateral prensiseta slightly larger than medial prensiseta.

Distribution. Ecuador.

Type data. Holotype ♀ ( CDFA USNMENT00104213 ), ECUADOR: Napo: Huahua Sumaco, Hollin - Loreto road, km 44, Malaise trap, 14 Dec 1989, M. & J. Wasbauer & H. Real . Paratypes: Same data as holotype, 16 Dec 1989, 1♂ ( CDFA USNMENT00104212 ) .

Etymology. The name of this species is a noun in the genitive case in honor of Marius S. Wasbauer, one of the collectors of the type specimens and the author of a very useful catalog of tephritid host plants.
