Diagnosis. This species is among the Blepharoneura species with the apical part of the wing obliquely banded, usually 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; scutum with pair of submedial brown vittae, interrupted at transverse suture, and with brown band or triangular to trapezoidal mark on posterior margin; anepisternum without brown markings; abdominal tergites with pair of broad solid dark brown vittae without yellow spots and with even margins, not extending to lateral margins of tergites, which are yellow; cell c hyaline to diffuse pale brown except margins (without complete brown medial mark dividing distinct subbasal and subapical hyaline spots); distal hyaline mark in cell m ending at vein M or at most extending midway across cell r4+5. The aculeus of B. brevivittata resembles those of B. bivittata and fernandezi in having a very broad, deep medial concavity. It is intermediate between those two species in the width of the medial concavity, and the relative length of the tip is less than in both species.

Description. Head: Dark brown area on ocellar tubercle almost always (17 of 18 specimens) extended beyond postocellar seta. Medial vertical seta in ovoid or triangular dark brown spot mostly posteromesal to seta or in narrow to broad band extended to opposite seta and usually connected to area on ocellar tubercle. Occipital suture narrowly dark orange to red brown. Sometimes with diffuse paler brown spot or small area including or ventral to lateral vertical seta.

Thorax ( Figs. 96–97 View FIGURES 94–97 ): Scutum nonmicrotrichose except posterior to dorsocentral seta and laterally, with pair of broad dark brown submedial presutural vittae, usually broadest at level of posterior margin of postpronotal lobe, usually extended almost to transverse suture. Posterior margin with broad, usually dark brown mark, variable in shape, usually triangular or trapezoidal, sometimes elongate, occasionally short and nearly linear (in Peruvian ♀ with 3 very narrow interruptions medially), often with paler submedial and/or sublateral vittae extending anteriorly, or with small isolated submedial spots. Scutellum entirely yellow (6 specimens), or with pair of submedial or sublateral brown spots, usually small, but moderately large in 2 males and extended to basal setae in one. Subscutellum and mediotergite rarely entirely yellow (Peruvian ♀), usually mediotergite with pair of broad brown vittae, sometimes reaching lateral margin, often (9 of 18 specimens) extended onto ventral half of subscutellum. Pleuron entirely yellow. Basalare entirely yellow. Dorsocentral seta aligned slightly posterior to postalar seta or with intra-alar seta.

Legs: Entirely yellow.

Wing ( Figs. 17–20 View FIGURES 16–25 ): Length 6.10–6.80 mm, width 2.80–3.37 mm, ratio 2.00–2.18. Crossvein r-m at 0.52– 0.59 distance from bm-cu to dm-cu. Cell c hyaline to diffuse pale brown except for darker brown basal area, very narrow slightly darker brown elongate medial or medial to distal area on costal margin, and dark brown distal area. Pterostigma occasionally (5 of 18 specimens) with large pale brown subapical spot [#3], sometimes reaching R1, but usually without spot. Cells r1 and r2+3 basally (proximal to apex of R1) without hyaline spots. Radial cells medially with slightly to usually strongly tapering basal marginal hyaline mark [#5] in cell r1 and aligned spot in r2+3 [#8] and sometimes r4+5 [#14] forming acute triangular to nipple-shaped mark, usually reaching R4+5 (except in 1 specimen and 1 wing of 2 others), or sometimes (5 of 17 specimens) extended into but less than midway across r4+5 or rarely (1 specimen) with narrowly isolated aligned spot in r4+5; cell r4+5 with medial hyaline spot [#15] near anterior end of dm-cu small or usually minute, often yellowish, occasionally absent. Distally cell r1 without hyaline spots [#6]. Cell r2+3 usually without marginal hyaline marks. Cell r4+5 with hyaline band from posteroapical margin, extending more or less parallel to costa into cell r2+3, usually almost reaching vein R2+3, occasionally (3 specimens) reaching it and rarely (1 wing of 1 specimen) also reaching costa, often irregular with slight constrictions, especially along vein R4+5, slightly to much broader than marginal brown area. Cells m and r4+5 usually with inverted V-shaped mark [fusion of #26A, #26, #27, #29 plus additional spots], extending anteriorly halfway across cell r4+5, but distal arm often constricted along vein M or connected to proximal arm only within cell m, occasionally (2 Costa Rican specimens) with 2 separate marks, only proximal mark extending into r4+5, or (Peruvian ♀) with 2 marks and neither (1 wing) or only distal mark extending into r4+5; both arms or marks reaching posterior margin in cell m. Cell br usually with subbasal hyaline spot [#12], absent in Peruvian female. Cell bm usually without circular subbasal hyaline spot [#19] (present in 2 Costa Rican specimens), usually with circular medial or subapical hyaline spot [#20], absent in Peruvian female. Posteromedial part of wing with 2 ( Panama ♂) or usually 3 sets of aligned, partially fused spots and bands or with single broad, more fused irregular marking; cell br with subapical hyaline spot [#13] and often (10 specimens on at least 1 wing) with more proximal small posterior yellowish or hyaline spot [#44]; cell dm usually (except in Panama ♂) with elongate subbasal hyaline mark [fused #51, #52] aligned with spot [#44] in cell br (when present) and proximal anterior spot in cell cu1 [#31], separate ( Peru ♀) or (Costa Rican specimens) with this mark partially or completely fused to somewhat L-shaped mark [fused #21, #22, #24, sometimes #50] to form elongate mark, longer posteriorly than anteriorly; cell cu1 with proximal anterior spot [#31] aligned with subbasal mark in cell dm absent ( Panama ♂), small and isolated ( Peru ♀), or usually (most Costa Rican specimens) connected with or fused to posteromedial hyaline mark [fusion of #32, #33, #36] to form trident shaped or vase shaped mark, or with this mark also connected to mark crossing vein A1+Cu2 [fused #34, #39]; subapical marginal hyaline mark [#37] usually present, sometimes small or diffuse, absent in 1 Costa Rican specimen. Cell dm usually without subapical spot [#25], small in 3 Costa Rican specimens, rarely (1 wing of 1 Costa Rican ♀) larger but broadly connected to large medial hyaline area.

Abdomen ( Fig. 124 View FIGURES 119–125 ): Yellow, with pair of broad dark brown vittae on all tergites, mark on syntergite 1+2 sometimes isolated as spot, vittae with relatively even margins, not extending to lateral margins of tergites and separated medially by broad, tapering, straight margined yellow area; brown vittae solid, without yellow spots within them; lateral margins of tergites without brown markings.

Female terminalia: Oviscape entirely dark brown; length 0.85–1.00 mm. Aculeus ( Fig. 127 View FIGURES 126–135 ) 0.72–0.80 mm long, 1.56–1.58 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip flared outward basolaterally, short and broad (lobed part 0.17–0.21 times as long as wide), with broad, moderately deep medial apical concavity (almost as deep as length of medial lobes and about half as broad as distance between apices of submedial lobes) and with 4 pairs of lobes separated by deep gaps; lateral lobe projecting, moderately broad and blunt; sublateral lobe smaller and narrower but also projecting, with 1 to several minute serrations; submedial lobe smaller and more step-like; medial lobe short and blunt. Spermathecae subspherical to subconical or with apical projection, neck with very short, straight, weakly sclerotized basal part, abruptly expanded to very stout, cylindrical, sclerotized part, and with large stout cylindrical basal apodeme.

Male terminalia: Medial surstylus with prensisetae separated by several times width of medial prensiseta, medial prensiseta on long lobe, lateral prensiseta subequal to medial prensiseta.

Distribution. Lowland areas of Costa Rica, Panama, and eastern Peru.
