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: scutum and scutellum without brown markings; vertex without brown markings; cells cu1 and dm with 2 relatively straight and narrow hyaline bands; and cell r4+5 without hyaline spot near crossvein dm-cu. The aculeus is similar to those of B. bivittata , B. brevivittata , and B. fernandezi in having a broad medial apical concavity, but unlike those species, it has a the sublateral lobe broad, slanted and finely serrate, similar to B. furcifer , B. rupta , and B. cornelli , which differ in having a projecting medial lobe and much smaller submedial lobes.

Description. Head: Dark brown area on ocellar tubercle extended less than half distance to postocellar seta. Occipital suture narrowly orange brown.

Thorax: Scutum nonmicrotrichose except posterior to dorsocentral seta, laterally, and anterolateral third of presutural part; entirely yellow, without dark markings. Scutellum, subscutellum, mediotergite, pleuron and basalare entirely yellow. Dorsocentral seta aligned slightly posterior to postalar seta.

Legs: Entirely yellow.

Wing ( Fig. 42 View FIGURES 36–45 ): Length 5.25–6.53 mm, width 2.60–3.21 mm, ratio 1.91–2.03. Crossvein r-m at 0.47–0.55 distance from bm-cu to dm-cu. Cell c with 2 ovoid hyaline spots, sometimes narrowly separated from costa and/or subcosta by very pale brown areas; medial brown area as dark as area of cell r1 posterior to pterostigma, with paler medial spot or streak, medial brown area equal to slightly broader than hyaline spots. Pterostigma without subapical hyaline spot. 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 [#8] in r2+3 forming acute triangular mark, reaching R4+5 or sometimes (1 specimen with small aligned anterior spot [#14]) extended slightly into r4+5; cell r4+5 without medial hyaline spot [#15] near anterior end of dm-cu. Distally cell r1 without hyaline spots [#6]. 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 to not tapering anteriorly, much broader than marginal brown area. Cells m and r4+5 with inverted V-shaped mark [fusion of at least #26, #26A, #27, #29], extending almost to vein R4+5 anteriorly and both arms reaching margin in cell m. Cell br with circular 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 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, and distal band [fused #24, #33, #36] extending from middle of cell dm to posterior wing margin, bands sometimes (1 wing of 2 specimens) connected narrowly in cell cu1 along vein Cu1; cell cu1 with subapical marginal hyaline spot [#37] moderate to large. Cell dm without subapical hyaline spot [#25].

Abdomen: All tergites with pair of broad irregular dark brown markings, on syntergite 1+2 sometimes divided into 2 small marks on posterior margin; mark on each tergite extended along posterior margin to lateral margin of tergite; markings on tergites 3–5 bi- or trimodal or with 1–2 small to large anterior yellow spots within them; markings broadly separated medially by slightly tapering, nearly straight margined yellow area.

Female terminalia: Oviscape entirely dark brown; length 0.90–1.00 mm. Aculeus ( Fig. 129 View FIGURES 126–135 , 159 View FIGURES 156–164 ) 0.70– 0.75 mm long, 1.63–1.70 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip flared slightly outward basolaterally, short and broad (lobed part 0.27–0.30 times as long as wide), with broad, relatively deep medial apical concavity (1/2–2/3 as deep as length of medial lobes and 1/3– 2/5 as broad as distance between apices of submedial lobes) and with 4 pairs of lobes separated by deep gaps; lateral lobe digitiform, broad, minutely serrate; sublateral lobe very broad and slanted, minutely serrate; submedial and medial lobes short and blunt, similar in size. 8th sternite with pair of large setulae on medial apical corner. Spermathecae subspherical, with convoluted sclerotized neck and small to moderately large cylindrical basal apodeme.

Distribution. Lowland areas of Costa Rica.
