Diagnosis. This species can be distinguished from other species of Blepharoneura by the following combination of characters: Anepisternum and scutellum entirely yellow; scutum with pair of brown submedial vittae and broad triangular brown mark on posterior margin, but without sublateral vittae; cell r1 proximally with single relatively narrow, tapering marginal hyaline mark; cell r2+3 with 2 marginal hyaline marks, posterior one not connected to marginal hyaline spot in cell r4+5; cell r4+5 with single posterior marginal hyaline spot. It is very similar to B. thetis , which differs in having brown scutellar markings and 2 marginal hyaline spots or a bilobed spot in cell r4+5, and B. fernandezi , which lacks the brown mark on the posterior margin of the scutum and brown vittae on the mediotergite. The female is unknown.

Description. Head ( Fig. 88 View FIGURES 84–89 ): Dark brown area on ocellar tubercle extended more than half distance to postocellar seta. Large brown spot surrounding medial vertical seta extended ventromesally to level of postocellar seta. Occipital suture narrowly dark brown.

Thorax: Scutum nonmicrotrichose except posterior to dorsocentral seta and laterally, with pair of broad dark brown submedial presutural vittae, broadly interrupted at transverse suture but with short postsutural part connected to posterior brown mark. Posterior margin with broad elongate triangular dark brown mark, extended faintly lateral to base of scutellum. Scutellum entirely yellow. Subscutellum yellow. Mediotergite with pair of broad, narrowly separated red brown vittae. Pleuron entirely yellow. Basalare entirely yellow. Dorsocentral seta aligned slightly posterior to postalar seta.

Legs: Entirely yellow.

Wing (Fig. 69): Length 5.62 mm, width 2.90 mm, ratio 1.94. Crossvein r-m at 0.58 distance from bm-cu to dm-cu. Cell c with 2 rectangular hyaline spots, both reaching costa and subcosta; medial brown area slightly paler than area of cell r1 posterior to pterostigma, fainter anteriorly, and approximately as broad as 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 in cell r1 [#5] and with aligned spots in r2+3 [#8] and r4+5 [#14], sometimes forming acute triangular to nipple-shaped mark, but spot in r2+3 sometimes not extending to R2+3; cell r4+5 spot [#14] touching R4+5 but extended less than halfway across cell; cell r2+3 with more distal moderately large hyaline spot [#9], touching R4+5 but not R2+3; cell r4+5 with medial hyaline spot [#15] near dm-cu small. Distally cell r1 with 1 marginal subapical hyaline spot [#6]. Cell r2+3 with 2 elongate marginal hyaline marks [#10, 11], both extending to vein R4+5. Cell r4+5 with small hyaline spot [#16] on anterior margin aligned between marginal marks in cell r2+3, and with 1 moderately large, slightly elongate, obliquely anteriorly directed, marginal hyaline spot [#18] posteriorly, touching apex of vein M. Cell m with 3 small hyaline spots, 2 marginal [#27, 29] and 1 anteromedial [#26 and/or #26A], none extended to vein M. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20]. Posteromedial part of wing with hyaline spots mostly isolated; cell br with subapical spot [#13] and sometimes (1 wing) with smaller more proximal posterior spot [#44]; cell dm with subbasal hyaline band [fused #51, #52] aligned with more proximal spot in cell br [#44] (if present) and proximal anterior spot spot [#31] in cell cu1; dm also with small anterior medial spot [#21] aligned or partially aligned with subapical spot [#13] in cell br and with broad posteromedial spot [fused #22, #23, #24] or (1 wing) with these spots connected to form L-shaped mark; cell cu1 medially with 3 anterior hyaline spots [#31, #32, #33] and 2 marginal spots [fused #34, #39; #36], proximal anterior spot [#31] small, aligned with subbasal band in br, distal anterior spots [#32, #33] aligned with posteromedial spot in cell br, distal spot [#33] sometimes (1 wing) fused to medial marginal spot [#36] to form band; proximal marginal spot [fused #34, #39] across apex of vein A1+Cu2 isolated; subapical marginal hyaline mark [#37] small. Cell dm with subapical hyaline spot [#25] moderate sized, not extended to vein M.

Abdomen: Mostly yellow. Syntergite 1+2 with pair of small, faint brown sublateral spots, not reaching lateral or posterior margins. Tergites 3–5 with pair of broad dark brown spots, forming irregular vittae; spot on each tergite extended narrowly along posterior margin to lateral margin of tergite; spots broadly separated medially by tapering, straight margined yellow area; brown spots solid except for 1 small anterior yellow spot in spot on tergite 5.

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

Specimens examined. BOLIVIA: La Paz: 5 km W of Mapiri, Arroyo Tuhiri , 15°17.8'S 68°15.6'W, 750 m, 18 Mar 2001, S. D. Gaimari, 1♂ ( USNM USNMENT00056566 View Materials ) GoogleMaps .

Remarks. The single male examined probably represents an undescribed species, but we are reluctant to formally name it as no female specimens that can be associated with it or B. thetis are currently available.
