Blepharoneura sp. 8 : Norrbom & Condon 1999: 146.
Diagnosis. This species differs from other species of Blepharoneura by the following combination of characters: Scutellum dorsally and anepisternum entirely yellow; cell r2+3 between crossveins r-m and dm-cu more extensively hyaline than brown (spots large); and cell r4+5 with hyaline spot nearest to dm-cu less than 2/ 3 width of cell. The aculeus is most similar to those of B. chaconi and mikenoltei , lacking small scales on the medial membrane, and the tip with a moderately broad medial concavity and 4 pairs of step-like lobes. The gap between the medial and submedial lobes is more pronounced than in B. chaconi , and the medial concavity is narrower than in B. mikenoltei .
Description. Head: Dark brown area on ocellar tubercle extended less than half distance to postocellar seta or reaching level of that seta medially. Medial occipital sclerite with pair of pale brown to red brown submedial vittae on ventral half. Occipital suture narrowly orange brown to dark brown.
Thorax: Scutum entirely microtrichose, often (16 of 24 specimens) with narrow brown spot or vitta bordering postpronotal lobe extending posteriorly at most to level of presutural supra-alar seta, occasionally (5 of 19 specimens) with small submedial brown spot aligned with or slightly posterior to postsutural supraalar seta; posterior margin with 2 well separated brown marks, sometimes small or pale; usually without other brown markings, rarely (1 specimen [USNMENT00213818]) with posterior brown spot on notopleuron and L-shaped vitta from anterior to postsutural supra-alar seta to postalar seta or (2 specimens) with small brown spot anterior to postalar seta. Scutellum entirely yellow. Subscutellum and mediotergite with pair of narrow to moderately broad brown vittae, rarely (3 specimens) also with ventral half of lateral margin of mediotergite brown or (1 specimen) both sclerites entirely yellow. Pleuron mostly or entirely yellow. Anepimeron usually (15 of 24 specimens) with small to moderately large pale brown to dark brown medial spot. Anatergite occasionally (3 specimens) with brown spot ventrally. Dorsocentral seta aligned with or slightly anterior or posterior to postalar seta.
Legs: Entirely or mostly yellow. Mid or hind femora occasionally (Guatemalan specimens, 2 Mexican specimens [USNMENT00213807–08]) with slightly darker orange to brown anteroventral and posteroventral apical marks.
Wing ( Figs. 46–47 View FIGURES 46–55 ): Length 6.14–6.80 mm, width 2.83–3.15 mm, ratio 2.10–2.27. Crossvein r-m at 0.53– 0.55 distance from bm-cu to dm-cu. Cell c with 2 broad rectangular hyaline spots, both reaching costa and subcosta; medial brown area almost as dark as to distinctly paler than area of cell r1 posterior to pterostigma, sometimes faint medially or posteriorly, distinctly narrower than both hyaline spots. Pterostigma usually with subapical hyaline to pale brown spot [#3] (absent in 2 of 24 specimens) but size of spot variable, often faint, minute or small but occasionally reaching R1. Cells r1 and r2+3 basally (proximal to apex of R1) usually without hyaline spots or only with spot in r1 posterior to apex of vein Sc, occasionally (2 Guatemalan specimens) with 1–2 small hyaline spots in cell r2+3. Radial cells medially with 1 broad quadrate basal marginal hyaline mark [#5 fused with additional spot?] in cell r1; cell r2+3 with 2 broad hyaline spots [#8, #9] or 1 extremely broad hyaline mark, sometimes partially divided, posterior to r1 mark; cell r4+5 with large hyaline spot [#14] aligned with r1 mark, extending from R4+5 halfway to completely across cell, small to large hyaline spot [#15] aligned with or slightly distal to dm-cu, and often (11 of 21 specimens) with anterior hyaline spot [#48] near midlength not touching vein R4+5. Distally cell r1 usually with 1 marginal hyaline spot [#6], rarely (1 Guatemalan ♂) without spots or (3 Mexican specimens) with second small marginal spot; without posterior spots. Cell r2+3 with 2 large marginal hyaline marks [#10, #11], occasionally partially connected or brown area between them sometimes pale and diffuse, both extending to or almost to vein R4+5, proximal spot rarely (2 specimens) divided into marginal and posterior spots. Cell r4+5 usually (except 2 Guatemalan males) with small hyaline spot [#16] anteriorly, usually aligned between apical marks in cell r2+3; with small to large ovoid posterior hyaline spot aligned with proximal mark or between hyaline marks in cell m; and with 1 large, often bilobed marginal or submarginal hyaline spot [probably fused #18 and #18A] or rarely (2 Mexican specimens, 1 wing of holotype) with 2 separate small ovoid hyaline spots [#18, #18A]. Cell m sometimes (9 of 21 specimens) with subbasal hyaline spot [#49] near midlength of dm-cu; and with 2–3 large ovoid hyaline spots, 2 marginal [#27, #29] and 1 anteromedial spot [fused #26A, #26], or usually with anteromedial and proximal spots connected or fused to form elongate mark. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20], often connected medially, or with single broad hyaline area [fused #19, #20]. Cell bcu rarely (2 specimens) with hyaline spot in lobe and extending anteriorly into cell cu1. Posteromedial part of wing with large broad hyaline areas; cell br with large subapical hyaline spot [#13] and often with smaller more proximal spot [#44]; cell dm with long broad hyaline area [fusion of at least #51, #52, #21, #22, #23, #24, #50, often #25?], sometimes partially divided medially, aligned with broad hyaline area in cell cu1, tapering distally and broadest posteriorly or more transverse distally or with anterodistal extension [if connected or fused with #25]; cell cu1 with large medial hyaline area [fusion of at least #31, #32, #33, #34, #36], anteriorly trilobed and posteriorly bilobed, or more broadly fused, including 1 or usually 2 small anterior and 1 subbasal marginal or submarginal brown spots; subapical marginal hyaline spot [#37] large, reaching or almost reaching vein Cu1. Cell dm with large anterior subapical hyaline spot [#25?] usually connected to or fused with proximal hyaline area (sometimes not obviously discernable), and occasionally (5 specimens) with very small posterior hyaline spot [#53] aligned with subapical mark in cell cu1.
Abdomen: All tergites with 4 evenly spaced dark brown spots, sublateral pair sometimes absent on syntergite 1+2, and 2 pairs of spots (more medial pair sometimes absent on syntergite 1+2) or pair of posterolateral dark brown bands on posterior margin, on tergites 3–5 L-shaped but lateral margin yellow anteriorly, bands separated medially except occasionally on tergite 5; sublateral spot sometimes connected to posterior band on tergites 3 or 4.
Female terminalia: Oviscape entirely dark brown; length 1.00– 1.20 mm. Aculeus ( Figs. 146–148 View FIGURES 146–155 , 169 View FIGURES 165–172 ) 0.76–0.84 mm long, 2.45–2.86 times as long as wide, without scales dorsally or ventrally on membrane medially; tip angular basolaterally, relatively short triangular (lobed part 0.40–0.51 times as long as wide), with moderately broad, shallow medial apical concavity (less than 1/4 as broad as distance between apices of submedial lobes) and 4 pairs of step-like lobes; sublateral and submedial lobes similar in size; lobes separated by moderately deep gaps, lateral gap 1.50–2.00 times as long as wide, gap between medial and submedial lobes about half as long as wide. Spermathecae subspherical, with straight to slightly convoluted, slender sclerotized neck and large cylindrical basal apodeme.
Male terminalia: Medial surstylus with prensisetae separated by several times width of medial prensiseta, medial prensiseta on curved lobe, lateral prensiseta small, less than half as wide as medial prensiseta, acute, dark brown ( Fig. 201 View FIGURES 200–203 ).

Etymology. The name of this species is an adjective referring to the country where most of the type series was collected.
Biology. One adult specimen was collected on a species of Cucurbita , but there is no indication that the plant is a host. The Guatemalan specimens were reared from larvae mining stems of a species of Sicyos , possibly longisepalus Cogn. ( Figs. 215–218 View FIGURES 215–218 ). The larvae are slender compared to those of fruit and flower infesting Blepharoneura species.
