Hexachaeta rupta Wulp 1899: 402 [in key], 404 [description]; Foote 1965: 237 [type data and lectotype designation]. Blepharoneura rupta: Hendel 1914: 20 [in key], 21 [in catalog]; Aczél 1950: 198 [in catalog]; Foote 1967: 18 [in catalog]; Norrbom et al. 1999: 106 [in catalog].

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: vertex with brown spot or band surrounding medial vertical seta; scutum without vittae or with 3 vittae or anterior spots, including unpaired medial one; anepisternum without brown markings; pterostigma without subapical hyaline spot; cell m with proximal hyaline mark extending at least to vein R4+5, distal mark often not extended beyond vein M; subapical hyaline band not extended anteriorly to vein R2+3 nor with aligned posterior spot in cell r1 and not extended proximally beyond the apex of the proximal hyaline band originating in cell m; and abdominal tergites 3–5 with brown mark extended to lateral margin or with small separate spot on margin. The aculeus is similar to those of B. cornelli and furcifer , with minutely serrate, digitate lateral and broad slanted sublateral lobes, a step-like submedial lobe, and unpaired truncate or convex medial lobe.

Description. Head: Dark brown area on ocellar tubercle extended more than half distance to postocellar seta or reaching it. Small dark brown area surrounding and mostly posterior or posteromesal to medial vertical seta. Medial occipital sclerite with or without pair of faint brown submedial vittae on ventral half. Occipital suture narrowly dark orange to brown.

Thorax: Scutum nonmicrotrichose except posterior to dorsocentral seta and laterally, entirely yellow ( Rio Naranjo ♀) or with narrow unpaired presutural medial red brown vitta extending to or beyond transverse suture, and presutural pair of short comma-shaped red brown vittae or spots aligned with medial corner of postpronotal lobe; posterior margin usually (2 of 3 specimens) with broad dark brown band or triangular mark. Scutellum , mediotergite and pleuron entirely yellow. Subscutellum entirely yellow ( Rio Naranjo ) or with small brown spot or line dorsolaterally ( USNM paralectotype, Stann Creek). Basalare entirely yellow. Dorsocentral seta aligned with or slightly posterior to postalar seta .

Legs: Entirely yellow.

Wing ( Figs. 4 , 60 ): Length 5.20–6.40 mm, width 2.50–3.15 mm, ratio 1.93–2.08. Crossvein r-m at 0.52– 0.57 distance from bm-cu to dm-cu. Cell c with 2 ovoid hyaline spots, basal spot and sometimes distal spot not reaching costa and/or subcosta; medial brown area as dark as area of cell r1 posterior to pterostigma, with medial, streak-like pale area, dark brown medial area as broad or broader than both spots. Pterostigma without subapical hyaline spot. Cells r1 and r2+3 basally (proximal to apex of R1) without hyaline spots or only with spot in r1 posterior to apex of vein Sc. Radial cells medially with tapering basal marginal hyaline mark [#5] in cell r1 and aligned spot in r2+3 [#8] forming acute triangular mark, usually extended to R4+5; no aligned spot present in r4+5; cell r2+3 sometimes (1 of 4 specimens) with second, slightly more distal, small hyaline spot [#9], extending from R2+3 more than halfway to R4+5; cell r4+5 with medial hyaline spot [#15] near anterior end of dm-cu small. Distally cell r1 without hyaline spots [#6]. Cell r2+3 without marginal hyaline marks but with 2 large spots [apical parts of #10, #11] or 1 very broad hyaline area posteriorly bordering R4+5, proximal spot isolated or connected to band in cell r4+5. Cell r4+5 with hyaline band from posteroapical margin, extending parallel to costa into cell r2+3, as broad as to much broader than marginal brown area. Cell m with 2 elongate marginal hyaline marks, proximal mark [fused #26A, #26, #27] aligned with hyaline band in cell r4+5 forming band extending at least to vein R4+5, distal mark [#29] isolated and ending at vein M or connected to proximal mark along posterior or both sides of vein M. Cell br with subbasal hyaline spot [#12]. Cell bm without subbasal hyaline spot [#19], with small circular subapical spot [#20] only. Posteromedial part of wing with 2– 3 hyaline marks; cell br with subapical hyaline spot [#13] aligned and connected with anterior spot in cell dm [#21] to form narrow band; cell dm with 2 narrowly separated posteromedial spots or 1 broad spot [#22, #23?, #24], proximal part (or spot) sometimes connected to anterior mark, aligned with proximal part of Y- or Hshaped mark in cell cu1; cell cu1 with Y-shaped hyaline mark [fusion of #32, #33, #36], its proximal arm aligned with and sometimes connected to spot [fused #34, #39] across apex of vein A1+Cu2 to form H-shaped mark, isolating 1–2 brown spots; subapical marginal hyaline mark [#37] moderate to large. Cell dm with subapical hyaline spot [#25] moderate sized (USNM paralectotype) or usually absent.

Abdomen: All tergites with pair of broad irregular dark brown markings; mark on each tergite extended along posterior margin to lateral margin of tergite except on tergite 5 which has isolated posterolateral spot; markings on tergites 3–5 bimodal or with large anterior yellow spot within them; markings broadly separated medially by slightly tapering, nearly straight margined yellow area.

Female terminalia: Oviscape entirely dark brown; length 0.95–1.00 mm. Aculeus ( Fig. 161 ) 0.78–0.81 mm long, 1.98 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip slightly flared outward basolaterally, short triangular (lobed part 0.40–0.49 times as long as wide), with moderately long, broad truncate or blunt medial lobe and 3 pairs of lobes; lateral lobe large and digitiform, with minute serrations apically; sublateral lobe very broad and slanted, minutely serrate; submedial lobe small and step-like. Spermathecae subspherical, with strongly convoluted, broad sclerotized neck and with or without small cylindrical basal apodeme (similar to B. furcifer ).

Male terminalia: Medial surstylus long and slender, prensisetae subequal, closely approximated, separated by less than width of medial prensiseta ( Fig. 203 ).

Distribution. Lowland areas of tropical Mexico (Tabasco), Belize, and Costa Rica.
