description: <i>Blepharoneura quetzali</i> Norrbom &amp; Condon, new species Figs. 57, 150–151 <b>Diagnosis.</b> This species differs from all other <i>Blepharoneura</i> species in the shape of its aculeus, which is elongate triangular with a broad, shallow medial concavity and only 2 pairs of small step-like lobes. It can also be recognized by the following combination of characters: pterostigma without subapical hyaline spot; scutum with 2 pairs of brown vittae; anepisternum entirely yellow; cell r1 without subapical hyaline or pale brown spot; cell r2+3 distally with 1 marginal hyaline spot; and cell cell r4+5 distally with hyaline band across cell. It is similar to <i>B. variabilis</i> in wing pattern, but the spot in cell r4+5 near crossvein dm-cu [#15] is slightly distal to the crossvein, rather than aligned with or proximal to it as in <i>B. variabilis</i>. The aculeus has a much shallower medial concavity and fewer lobes (2 rather than 4 pairs) than that of <i>B. variabilis</i>. <b>Description.</b> Head: Dark brown area on ocellar tubercle extended more than half distance to postocellar seta. Medial occipital sclerite with pair of pale brown submedial vittae on ventral half. Occipital suture narrowly brown. Thorax: Scutum entirely microtrichose, with 2 pairs of dark brown vittae; submedial vitta paler anterior to transverse suture and interrupted posterior to suture, not connected to mark on posterior margin; sublateral vitta ending at transverse suture; posterior margin with pin medially in holotype, with brown marking (probably 2 separate spots). Notopleuron with small posterior brown spot on lateral margin. Small brown spots anterior to postsutural supra-alar seta, anterior to postalar seta, and lateral to dorsolateral corner of scutellum present, latter faint. Scutellum entirely yellow. Subscutellum and mediotergite with pair of dark brown vittae, moderately broad. Pleuron mostly yellow, sometimes with small brown medial spot on anepimeron (right side). Basalare with faint brown spot. Dorsocentral seta aligned slightly anterior to postalar seta. Legs: Mostly yellow. Mid and hind femora with elongate, moderately broad anteroventral and posteroventral brown marks on apical 1/4. Wing (Fig. 57): Length 6.83 mm, width 3.22 mm, ratio 2.12. Crossvein r-m at 0.55 distance from bm-cu to dm-cu. Cell c with 2 rectangular hyaline spots, both reaching costa and subcosta; medial brown area distinctly paler than area of cell r1 posterior to pterostigma, fainter medially, and very slightly narrower or broader than hyaline spots. Pterostigma without subapical hyaline spot. Cells r1 and r2+3 basally (proximal to apex of R1) with orange spot in cell r1 posterior to apex of vein Sc. Radial cells medially with relatively narrow, tapering basal marginal hyaline mark [#5] in cell r1 and with aligned spots in r2+3 [#8] and r4+5 [#14], spot in r2+3 not reaching R2+3 but touching R4+5; aligned spot [#14] in r4+5 broadly touching R4+5, about half as wide as cell, not extended to vein M; cell r2+3 with more distal, moderately large hyaline spot [#9], touching R2+3 and R4+5; cell r4+5 with spot [#15] anterior and slightly distal to crossvein dm-cu, without additional anterior hyaline spot [#48] near midlength. Distally cell r1 without hyaline spot [#6]. Cell r2+3 with 1 marginal hyaline mark [#10] at apex of R2+3, extending to vein R4+5, sometimes broad posteriorly [fused with interior part of #11] and narrowly separated from distal hyaline mark in cell r4+5, or with separate more distal posterior hyaline mark [interior part of #11] aligned with and connected to distal hyaline mark in cell r4+5 forming band extending to posteroapical margin of r4+5, part of band in r4+5 relatively straight or concave. Cell r4+5 also with large posterior hyaline spot aligned with hyaline marks in cell m. Cell m with 2 elongate marginal hyaline marks [proximal mark fusion of #26A, #26 and #27; distal mark #29], both or only distal mark connected to spot in cell r4+5 forming band or inverted V-shaped mark. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20]. Posteromedial part of wing with several large hyaline markings; cell br with large subapical hyaline spot [#13]; cell dm with 1 broad broad hyaline mark in basal 3/ 5 [fused #51, #52, #21, #22, #23 and/or #24] extending proximal to subapical spot [#13] in cell br, proximal part aligned with proximal anterior spot in cell cu1 [#31], broader posteriorly than anteriorly; cell cu1 medially with 3 anterior [#31, #32, and #33] hyaline marks, at least distal 2 connected to medial marginal spot [#36] to form Y-shaped or trident shaped mark, separated from proximal marginal hyaline spot [#34]; subapical marginal hyaline spot [#37] not extending to vein Cu1. Cell dm with anterior subapical hyaline spot [#25] relatively large, extended to vein M. Abdomen: All tergites with 4 evenly spaced dark brown spots, L-shaped posterolateral dark brown band or separate lateral and posterior spots, separated medially, and on tergites 3–4 anterolateral dark brown spot. Female terminalia: Oviscape entirely dark brown; length 1.3 mm. Aculeus (Figs. 150–151) 0.9 mm long, 3.75 times as long as wide, without scales dorsally or ventrally on membrane medially; lateral margin with minute serrations basally on tip; tip subtriangular and relatively long (tapered part 0.71 times as long as wide), with broad shallow medial apical concavity bordered by 2 pairs of small step-like lobes; medial and submedial lobes separated by elongate shallow gap slightly longer than wide. Spermathecae subspherical, with long, straight, slender sclerotized neck and with small cylindrical basal apodeme. <b>Distribution.</b> Guatemala. The holotype was collected at 1600 m elevation in the Universidad del Valle reserve on the Pacific side of Volcán Atitlan. <b>Type data.</b> Holotype &amp;female; (FSCA USNMENT00654000), GUATEMALA: Suchitepéquez: Santa Barbara, Reserva Refugio Quetzal UVG, 14.5418°N 91.1973°W, 1600 m, Malaise trap, 10–20 May 2007, J. P. Pérez. <b>Etymology.</b> The name of this species is a noun in the genitive case derived from the name of the Universidad del Valle reserve where the holotype was collected.
