 Diagnosis. This species differs from other species of Blepharoneura with the distal part of the wing banded in having only a single marginal hyaline mark in cell r2+3, and that mark broadly touching the costal margin in r2+3 and extending from the apex of vein R2+3 to the apex of vein M. Other useful diagnostic characters include: scutellum without brown markings; pterostigma with subapical hyaline spot; cell r1 without subapical hyaline spot; cell dm without hyaline subapical spot in anterior half; and abdominal tergites 3–5 with pair of broad dark brown submedial vittae and separate small posterolateral spot. The aculeus tip is very short and broad. It resembles those of B. ruptafascia, bidigitata and hirsuta, but the lateral lobe is rounded unlike B. ruptafascia, but not digitate as in B. bidigitata and hirsuta.   
 Description. Head: Dark brown area on ocellar tubercle extended more than half distance to postocellar seta. Occipital suture narrowly dark brown.   
Thorax: Scutum entirely microtrichose, with 1 submedial pair of dark brown vittae from anterior margin halfway to transverse suture; posterior margin with pair of well separated rounded dark brown marks. Scutellum, subscutellum, mediotergite and pleuron entirely yellow. Basalare entirely yellow. Dorsocentral seta aligned slightly anterior to postalar seta.  
Legs: Mostly yellow. Mid femur with dark red brown spot on margin of anteroventral apical ridge, hind femur with similar but smaller and paler mark. Hind tibia slightly darker, orange.  
Wing (Fig. 70): Length 7.43 mm, width 3.76 mm, ratio 1.97. Crossvein r-m at 0.48 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 faint anteriorly, paler than area of cell r1 posterior to pterostigma, narrower than both hyaline spots. Pterostigma with large subapical hyaline spot [#3] reaching R1. Cells r1 and r2+3 basally (proximal to apex of R1) without hyaline spots. Radial cells medially with tapering basal marginal hyaline mark [#5] in cell r1 and aligned spots in r2+3 [#8] and r4+5 [#14] forming acute triangular to nipple-shaped mark, extended slightly more than halfway across cell r4+5; cell r2+3 with more distal small hyaline spot [#9], touching R4+5 and touching or almost touching R2+3; cell r4+5 with medial hyaline spot [#15] near anterior end of dm-cu small. Distally cell r1 without marginal [#6] or posterior hyaline spots. Cells r2+3 and r4+5 distally with 1 broad, nearly straight hyaline band extending from margin at apex of R2+3 to posteroapical margin of cell r4+5. Cell m with 2 marginal hyaline marks, proximal mark [fused #26, #27] extending 3/4 distance to vein M, distal mark [#29] extending to vein M. Cell br with subbasal hyaline spot [#12]. Cell bm with only circular subapical hyaline spot [#20]. Posteromedial part of wing with large inverted Y- or V-shaped hyaline mark; proximal part [aligned and connected #13, #21, #22, #32, #34, #39] extending from cell br subapically, across cells dm and cu1 subbasally, and across apex of vein A1+Cu2, broadly connected posteriorly in cell dm to distal band [fused #24, #33, #36] extending from posteromedially in cell dm to posterior wing margin; cell cu1 with subapical marginal hyaline mark [#37] moderate sized. Cell dm without subapical hyaline spot [#25].  
Abdomen: Mostly yellow. Syntergite 1+2 with 1 pair of dark brown spots not reaching lateral or posterior margins. Tergites 3–5 with pair of broad dark brown submedial vittae, not extended to lateral margin, but each tergite also with small posterolateral spot on margin; submedial vittae solid brown, without yellow spots within them but on tergites 4 and 5 narrowed on posterior half, well separated medially, but with irregular margins.  
Female terminalia: Oviscape entirely dark brown; length 1.30 mm. Aculeus (Fig. 164) 0.94 mm long, 1.96 times as long as wide, with acute scales dorsally and ventrally on medial membrane; tip broad and short (lobed part 0.24 times as long as wide), with small convex weakly trilobe medial lobe and 3 pairs of additional lobes; sublateral lobe bluntly acute, much larger than submedial lobe, which is somewhat step-like and poorly developed; lateral lobe broadly rounded but not digitate; gaps between lobes shallow except that between lateral and sublateral lobes, gap between sublateral and submedial lobes very broad and transverse, submedial and medial lobes together less than 1/4 as wide as distance between apices of sublateral lobes. Spermathecae subspherical, with slender, straight sclerotized neck and with large cylindrical basal apodeme.  
 Distribution. Ecuador. The holotype was collected at 340 m elevation.   
 Type data. Holotype ♀ (UKaL USNMENT00213920), ECUADOR: Napo: Santa Cecilia, 340 m, 8 Jun - 1 Aug 1968, W. G. Saul.   
 Etymology. The name of this species is a Latin adjective referring to the single apical hyaline band crossing cell r2+3.
