 Diagnosis. This species is among the Blepharoneura species with the apical part of the wing obliquely banded, without marginal hyaline marks in cell r2+3. It differs from the other obliquely banded species by the following combination of characters: vertex with brown spot or band surrounding medial vertical seta; medial occipital sclerite with pair of brown submedial vittae on ventral half; anepisternum without brown markings; pterostigma without subapical hyaline spot; cell r4+5 without hyaline spot near crossvein dm-cu; subapical hyaline band not extended anteriorly to vein R2+3 nor with aligned posterior spot in cell r1 but extended proximally beyond the apex of the proximal hyaline band originating in cell m; and abdominal tergites 3–5 with brown mark or spot on lateral margin. The aculeus is similar to those of B. rupta and furcifer, with minutely serrate, digitate lateral and broad slanted sublateral lobes, a step-like submedial lobe, and unpaired truncate or convex medial lobe, but the lateral lobe is narrower than in those species and the medial lobe is shorter than in B. rupta.   
 Description. Head: Dark brown area on ocellar tubercle extended less than half distance to postocellar seta. Small dark brown area surrounding and extending posteromesal to medial vertical seta. Medial occipital sclerite with pair of faint brown submedial vittae on ventral half. Occipital suture narrowly dark orange.   
Thorax: Scutum nonmicrotrichose except posterior to dorsocentral seta and laterally, mostly yellow, with pair of short comma-shaped pale brown vittae near anterior margin aligned with medial corner of postpronotal lobe. Scutellum, subscutellum, mediotergite, and pleuron entirely yellow. Basalare yellow. 2 pairs of dorsocentral setae present (missing in holotype except left posterior seta), posterior pair aligned between postalar and intra-alar setae, anterior (supernumery) pair aligned slightly anterior to postalar seta (right socket is slightly off dorsocentral line towards midline).  
Legs: Mostly yellow. Mid femur with narrow anteroventral brown mark on apical 1/4.  
Wing (Fig. 25): Length 5.95 mm, width 2.92 mm, ratio 2.03. Crossvein r-m at 0.51 distance from bm-cu to dm-cu. Cell c with 2 ovoid hyaline spots, neither reaching costa or subcosta, separated by very pale brown medial area with incomplete dark brown margins, rest of brown area except in base of cell as dark as area of cell r1 posterior to pterostigma, medial brown area broader than basal hyaline spot, as broad as distal spot. Pterostigma without subapical hyaline spot. Cell r1 brown except tapering nipple-shaped basal marginal hyaline mark [#5] extended to R2+3. Cell r2+3 without hyaline spots basal to level of dm-cu. Cell r4+5 with small hyaline spot [#14] touching R4+5 slightly distal to level of hyaline mark in r1; without hyaline spot [#15] near dm-cu. Distally cell r1 without hyaline spots [#6], and cell r2+3 without marginal hyaline marks. Cell r4+5 with hyaline band from posteroapical margin, extending more or less parallel to costa into cell r2+3 almost reaching vein R2+3, slightly tapering anteriorly, much broader than marginal brown area. Cells m and r4+5 with inverted V-shaped hyaline mark [fusion of at least #26A, #26, #27, #29], extending anteriorly to vein R4+5, both arms reaching margin in cell m. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20]. Posteromedial part of wing with 2 elongate hyaline marks, proximal one [aligned or fused #13, #21, #22, #32, #34, #39] extended from subapically in cell br to apex of vein A1+Cu2, sometimes narrowly interrupted anteriorly in cell dm or anteriorly in cell cu1, broadly connected posteriorly in cell dm to distal mark [aligned and fused #23, #24, #33, #36] extending to posterior wing margin in middle of cell cu1; cell cu1 subapical marginal hyaline mark [#37] moderate sized or absent. Cell dm without subapical hyaline spot [#25].  
Abdomen (Fig. 121): Tergites 3–6 each with submedial dark brown mark and narrow posterolateral dark brown mark; submedial markings broadly separated but with irregular margins, on tergite 3 connected with lateral mark on posterior margin to form trimodal mark, on tergites 4 and 5 U-shaped, and on tergite 6 divided into 2 spots, more lateral one connected to lateral mark on anterior margin; lateral mark on tergites 5–6 extended along entire lateral margin.  
 Female terminalia: Oviscape entirely dark brown; length 0.98 mm. Aculeus (Fig. 128) 0.87 mm long, 2.05 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip slightly flared outward basolaterally, short triangular (lobed part 0.41 times as long as wide), with short broad truncate medial lobe and 3 pairs of lobes; lateral lobe large and digitiform, with minute serrations apically; sublateral lobe very broad and slanted, minutely serrate; submedial lobe small and step-like. Spermathecae subspherical, with strongly convoluted, broad sclerotized neck and with or without small cylindrical basal apodeme (similar to B. furcifer).   
 Distribution. Costa Rica. The holotype was collected between 50–150 m elevation.   
 Type data. Holotype ♀ (INBio INBio001228576), COSTA RICA: Heredia: 3 km S of Puerto Viejo, Estación Biológica La Selva, 10°26'N 84°01'W, 50–150 m, 1 Jul 1993.   
 Etymology. In gratitude for financial support for our research on Blepharoneura, the name of this species is a noun in the genitive case honoring Cornell College, an innovative liberal arts college in Mount Vernon, Iowa that supports collaborative research between students and faculty.
