Diagnosis. This species resembles B. amplihyalina , apaapa , hyalinella , bipunctata and nigriapex in having a dark brown spot posterodorsally on the anepisternum, a single medial brown spot on the scutellum, and 3 hyaline marginal spots in cell m. It differs from all of them except B. bipunctata in having 2 narrow marginal hyaline marks basally in cell r1 rather than a single broad one, and from B. bipunctata in lacking an anepimeral brown spot and having a strong medial concavity on the aculeus tip.

Description. Head: Dark brown area on ocellar tubercle extended less than half distance to postocellar seta. Medial occipital sclerite with pair of brown submedial vittae on ventral half. Occipital suture narrowly dark brown.

Thorax: Postpronotal lobe mostly yellow, with small brown spot at junction with anepisternum and larger, diffuse brown spot on posterolateral margin. Scutum entirely microtrichose, with 2 pairs of dark brown vittae; submedial vitta interrupted slightly posterior to transverse suture and not connected to marks on posterior margin; sublateral vitta interrupted at transverse suture and separated from mark on posterior margin; posterior margin with 2 broad quadrate dark brown marks narrowly separated. Notopleuron dark brown except small yellow area surrounding posterior seta. Small brown spot anterior to postsutural supra-alar seta, large dark brown spot lateral to postsutural seta, small dark brown spot anterior to postalar seta, and large dark brown spot lateral to dorsolateral corner of scutellum present. Scutellum with single moderately large medial brown spot. Subscutellum and mediotergite with pair of moderately broad dark brown vittae. Pleuron mostly yellow. Anepisternum with dark brown spot dorsal to anterior seta. Anatergite dark brown except anterior corner and posterodorsal 1/4. Basalare entirely brown. Dorsocentral seta aligned slightly anterior to postalar seta.

Legs: Mostly yellow. Mid femur with dark brown spot on margin of anteroventral apical ridge. Hind femur with similar smaller spots on anteroventral and posteroventral apical ridges.

Wing ( Fig. 49 ): Length 8.12 mm, width 3.47 mm, ratio 2.34. 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 as dark as area in cell r1 posterior to pterostigma, much broader than basal hyaline spot and slightly broader than distal spot. Pterostigma with large subapical hyaline spot [#3] reaching or almost reaching R1. Cells r1 and r2+3 basally (proximal to apex of R1) with 3 and 2–4 pale brown spots, respectively. Radial cells medially with 2 narrow basal marginal hyaline marks in cell r1, both reaching R2+3, basal mark [#5] subovoid; cell r2+3 with 1 small hyaline spot [#8] aligned with basal mark in r1 and 1 broad or 2 narrowly connected spots [#9] aligned with second mark in r1; cell r4+5 with small hyaline spot [#14] in anterior half of cell aligned with proximal r1 mark, with small hyaline spot [#15] aligned with dm-cu, and also with additional tiny hyaline spots, 4–5 near anterior margin and 3–4 on or near posterior margin. Distally cell r1 with 2 small marginal hyaline spots [#6 and additional spot]. Cell r2+3 with 2 marginal hyaline marks [#10, 11], proximal mark extending to vein R4+5 on right wing but divided into marginal spot and spot touching R4+5 on left wing. Cell r4+5 with small hyaline spot [#16] anteriorly, aligned between apical marks in cell r2+3 or with distal mark; with small posterior hyaline spot aligned with medial spot in cell m; and with 2 small rounded marginal hyaline spots [#18, #18A]. Cell m with small subbasal hyaline spot [#49] near midlength of dm-cu and another spot near anterobasal corner; with 3 ovoid marginal hyaline spots [proximal #27, distal #29], medial spot [fused #26, #26A, #28] largest, irregular, extended to vein M. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20]. Cell bcu with small hyaline spot in lobe. Posteromedial part of wing with very large hyaline marginal area; cell br subapically with hyaline spot [#13] and smaller, much more proximal spot; cell dm with 2–3 small subbasal hyaline spots [distal ones #51?, #52?] and larger ovoid posteromedial hyaline spot [fused #22?, #23, #24] (ca. 0.25 times as long as cell along vein Cu1) much shorter than hyaline mark in cell cu1 and aligned with its distal half; cell cu1 with minute anterior spot near base, and with large hyaline area covering medial half [broad fusion of at least #31?, #32, #33, #34, #36, #36A], very broad on posterior wing margin, lacking anterior brown spots and including 2 submarginal brown spots (distal 1 fainter); subapical marginal hyaline spot [#37] relatively small, not reaching vein Cu1. Cell dm with subapical hyaline spot [#25] moderate sized, and with smaller more distal anterior spot and posterior spot [#53] aligned with subapical mark in cell cu1.

Abdomen: Mostly yellow, with 4 rows of evenly spaced dark brown spots; tergites 3–5 also with anterolateral spot touching or almost touching lateral margin; syntergite 1+2 with dark brown spot in posterolateral corner and submedial band on posterior margin, and tergites 3–6 with L-shaped band in this area, separated medially, on tergites 4 and 5 connected to anterolateral spot.

Female terminalia: Oviscape entirely dark brown; length 0.90 mm. Aculeus ( Fig. 167 ) 0.70 mm long, 1.95 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip angular basolaterally, short triangular (lobed part 0.34 times as long as wide), with 4 pairs of lobes, medial pair short and convex, separated by medial concavity as broad as either lobe and as deep as half their length, other 3 pairs of lobes step-like; sublateral lobe larger than submedial lobe; lobes separated by deep gaps, lateral gap 0.89 times as long as wide. Spermathecae subspherical, with slightly convoluted, slender sclerotized neck and large cylindrical basal apodeme (similar to B. femoralis ).

Distribution. Ecuador. The holotype was collected at 2600 m elevation.

Type data. Holotype ♀ ( MZUSP USNMENT00213911 ), ECUADOR: Quito , Baeza, Papallacta, E of, 2600 m, Jan 1971, L. E. Peña.

Etymology. The name of this species is an adjective referring to the numerous spots on the wing.
