 Diagnosis. This species is among the species of Blepharoneura with two marginal hyaline marks in cell r2+3, the more distal of which is a concave band extending across cell r4+5. It differs from the other species with this type of wing marking by the following combination of characters: cell r1 without subapical hyaline spot; proximal marginal hyaline mark in cell r2+3 not extending into cell r4+5; and cell dm without hyaline subapical spot in anterior half. The aculeus tip is short and broad, with 3 pairs of step-like lobes and a small weakly trilobed medial lobe. The lateral lobe forms nearly a right angle, unlike in B. unifasciata in which the lobe is rounded.   
 Description. Head: Dark brown area on ocellar tubercle extended to level of postocellar seta. Occipital suture narrowly dark brown.   
Thorax: Scutum entirely microtrichose, with 2 pairs of red brown vittae; submedial pair extended from anterior margin to or almost to transverse suture and with pair of spots on anterior half of postsutural part of scutum; sublateral vitta extended from margin with postpronotal lobe halfway to transverse suture and with presutural spot on transverse suture; posterior margin with pair of rounded dark brown marks [holotype is pinned in this area, but spots probably well separated]. Notopleuron and scutellum entirely yellow. Pleuron entirely yellow. Subscutellum and mediotergite with pair of narrow brown vittae. Basalare entirely yellow. Dorsocentral seta aligned slightly anterior to postalar seta.  
Legs: Mostly yellow. Mid femur with dark brown spot on margin of anteroventral apical ridge, hind femur sometimes with similar but smaller and paler mark. Hind tibia slightly darker, orange.  
Wing (Fig. 61): Length 7.33 mm, width 3.86 mm, ratio 1.90. Crossvein r-m at 0.57 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, narrower than both hyaline spots. Pterostigma with large hyaline subapical spot [#3], reaching or almost 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 spot in r2+3 [#8] forming acute triangular to nipple-shaped mark, with spot [#14] in cell r4+5 slightly distal to it, and sometimes (1 wing) with spot in r2+3 bilobed posteriorly [fused spot #9?]; cell r4+5 spot [#14] barely touching R4+5 and extended halfway across cell, and with medial hyaline spot [#15] very small and slightly distal to anterior end of dm-cu. Distally cell r1 without marginal [#6] or posterior hyaline spots. Cell r2+3 with 2 elongate marginal hyaline marks, proximal mark [#10] ending at vein R4+5, distal mark [#11] connected with hyaline marks in r4+5 [including #18] forming concave band extending to margin of r4+5. Cell m with 2 elongate marginal hyaline marks [fused #26 and #27, #29], neither extending into cell r4+5. Cell br with subbasal hyaline spot [#12]. Cell bm with only circular subapical hyaline spot [#20]. Posteromedial part of wing with large inverted Y-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 to large. Cell dm without subapical hyaline spot [#25].  
Abdomen: Mostly yellow. Syntergite 1+2 with 1 pair of small brown submedial spots not reaching lateral or posterior margins. Tergites 3–5 with pair of broad dark brown submedial vittae or rows of spots, not extended to lateral margin, but each tergite also with small posterolateral spot on margin; submedial spots solid brown, without yellow spots within them but sometimes narrowed or broken into separate anterior and posterior spots, well separated medially, but with irregular margins.  
Female terminalia: Oviscape entirely dark brown; length 1.30 mm. Aculeus (Fig. 162) 0.89 mm long, 1.93 times as long as wide, with acute scales dorsally and ventrally on medial membrane; tip angular basolaterally, short triangular (lobed part 0.23 times as long as wide), with small, weakly trilobed medial lobe and 3 pairs of step-like lobes; sublateral lobe larger than submedial lobe, gap between them broad and transverse, submedial and medial lobe together almost 1/3 as wide as distance between apices of sublateral lobes; lateral lobe forming nearly 90° angle; lobes separated by deep gaps, lateral gap 1.04 times as long as wide. Spermathecae subspherical, with slender, slightly convoluted, sclerotized neck and with short cylindrical basal apodeme.  
 Distribution. Ecuador. The holotype was collected at 340 m elevation.   
 Type data. Holotype ♀ (UKaL USNMENT00213922), ECUADOR: Napo: Santa Cecilia, 340 m, 8 Jun - 1 Aug 1968, W. G. Saul.   
 Etymology. The name of this species is a Latin noun referring to the proximal hyaline marks in cells r2+3 and m which form an incomplete or broken second subapical band.   
 Remarks. A male from Costa Rica (Alajuela: Upala, 20 km S of, 5–10 Oct 1990, F. D. Parker (USU USNMENT00213921)) may be B. ruptafascia or a similar undescribed species. It differs as follows: scutum without postsutural submedial brown spots and with pair of spots on posterior margin faint and diffuse; notopleuron with small brown areas surrounding anterior and posterior setae; scutellum with pair of diffuse submedial red brown spots; subscutellum yellow except small, narrow brown mark on dorsal margin laterally, mediotergite entirely yellow; pterostigma with hyaline subapical spot [#3] smaller, not reaching R1; cell r1 basally with small hyaline spot posterior to apex of vein Sc; radial cells medially with hyaline spots separated, marks in cell r1 [#5] and r2+3 not reaching R2+3, spot in r2+3 [#8 or #9] nearly aligned with mark in r1 and spot in r4+5 [#14] in one wing and slightly distal to them in other; cell r4+5 with medial hyaline spot [#15] moderate sized and aligned with anterior end of dm-cu; cell r2+3 with distal hyaline mark [#11] not reaching margin in one wing; cell m on 1 wing with distal spot [#29] elongate but not reaching margin; cell bm with broad ovoid medial hyaline spot [fused #19 and #20?]; cell cu1 with subapical marginal hyaline mark [#37] small. Further specimens and data are needed to clarify the status of this male.
