 Diagnosis. This species is similar to B. chaconi in wing pattern, the relatively distal position of crossvein r-m, and aculeus shape but differs as follows: Cell r4+5 distally with 2 marginal or submarginal spots; cell dm proximal to r-m with 3–4 well separated hyaline spots; scutum without brown vittae; and scutellum dorsally without brown markings. The aculeus is similar to those of B. chaconi and mexicana, lacking small scales on the medial membrane, and the tip with a moderately broad medial concavity and 4 pairs of step-like lobes, but the tip is slightly more elongate and the medial concavity is broader than in those species. The holotype is teneral and although it is possible that its thoracic markings are not fully developed, the wing pattern and shape of the aculeus indicate that it is not conspecific with B. chaconi.   
 Description. Head: Dark brown area on ocellar tubercle extended less than half distance to postocellar seta. Medial occipital sclerite with pair of dark brown submedial vittae on ventral half. Occipital suture narrowly dark brown.   
Thorax: Scutum entirely microtrichose, yellow except pair of large quadrate dark brown spots near posterior margin. Notopleuron entirely yellow. Small faint brown spot anterior to postsutural supra-alar seta, diffuse brown spot lateral to postsutural supra-alar seta, small brown spot anterior to postalar seta, and faint brown spot lateral to dorsolateral corner of scutellum present. Scutellum entirely yellow. Subscutellum brown except medially. Mediotergite brown except medially and narrowly dorsolaterally. Pleuron mostly yellow. Anepimeron with large posteromedial brown spot extending to extreme anterior margin of katatergite. Anatergite with large posteroventral brown area. Basalare entirely yellow. Dorsocentral seta aligned slightly posterior to postalar seta.  
Legs: Mostly yellow. Hind femur with elongate, moderately broad anteroventral and posteroventral orange brown marks on apical 1/3. Mid femur with similar elongate but narrower anteroventral and posteroventral marks.  
Wing (Fig. 48) [teneral]: Length 7.35 mm, width 3.40 mm, ratio 2.16. Crossvein r-m at 0.65 distance from bm-cu to dm-cu. Cell c with 2 hyaline spots, basal spot narrow, not reaching costa on one wing, distal spot trapezoidal, reaching costa and subcosta; medial brown area slightly paler than area in cell r1 posterior to pterostigma, much broader than basal hyaline spot and slightly broader than distal spot. Pterostigma with small to large subapical hyaline spot [#3] touching R1 but not reaching costa. Cells r1 and r2+3 basally (proximal to apex of R1) each with 1–2 hyaline spots. Radial cells medially with 1 relatively narrow, rounded quadrate to slightly tapered basal marginal hyaline mark [#5] in cell r1; cell r2+3 with broad hyaline spot [#8] aligned with r1 mark and slightly more distal very broad hyaline spot [#9]; cell r4+5 with anterior spot [#14] slightly distal to r1 mark and large spot [#15] anterior to dm-cu, on left wing fused to form irregular spot, and with small anterior spot [#48] near midlength almost touching vein R4+5. Distally cell r1 with 1 small marginal subapical hyaline spot [#6], and with 2 more proximal small posterior hyaline spots. Cell r2+3 with 1 elongate marginal hyaline mark [#10] and 1 small rounded submarginal spot [#11], both extending to vein R4+5. Cell r4+5 with small hyaline spot [#16] on anterior margin aligned between apical marks in cell r2+3, with large posterior hyaline spot aligned with proximal spots in cell m, with 3 smaller rounded hyaline spots distal to it (1 near posterior margin, aligned with distal spot in m; 1 submarginal spot near posterior margin [#18], and 1 marginal or submarginal medial spot [#18A]). Cell m with 3 large hyaline spots, 2 marginal [#27, 29] and 1 anteromedial [fused #26A, #26], anteromedial and distal spots almost touching 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 multiple large hyaline spots and marks; cell br with moderately large ovoid subapical hyaline spot [#13] and smaller more proximal spot [#44]; cell dm with broad spot subbasally across cell [fused #51, #52, sometimes #21?], broader anteriorly or subquadrate, its proximal part aligned with spot in cell br [#44] and proximal branch of trilobed fork in cell cu1 [#31]; cell dm sometimes (1 wing) with separate hyaline anterior spot [#21] aligned with subapical spot in cell br [#13], with isolated anterior spot [#50] aligned with or slightly proximal to r-m, and with broad posteromedial spot [#23 and/or #24] aligned with distal branches of tribobed mark in cell cu1; cell cu1 medially with large trilobed hyaline mark [fusion of at least #31, #32, #33, #36], proximally narrowly separated from marginal mark [fused #34, #39] across apex of vein A1+Cu2; medial and distal branches of mark sometimes (1 wing) largely fused; subapical marginal spot [#37] moderate sized. Cell dm with subapical hyaline spot [#25] moderately large, extended to vein M; also with posterior subapical hyaline spot [#53] touching vein Cu1 aligned with subapical spot in cell cu1.  
Abdomen: Mostly yellow, all tergites with 4 rows of evenly spaced dark brown spots and with paired bands on posterior margin, separated medially, on tergites 3–6 extending anteriorly on entire lateral margin.  
Female terminalia: Oviscape entirely brown; length 1.32 mm. Aculeus (Fig. 168) 1.10 mm long, 3.41 times as long as wide, without scales dorsally or ventrally on membrane medially; tip angular basolaterally, moderately elongate triangular (lobed part 0.54 times as long as wide), with broad shallow medial apical concavity (about half as broad as distance between apices of submedial lobes) and 4 pairs of step-like lobes; sublateral lobe larger than submedial lobe; lobes separated by long, relatively shallow gaps, lateral gap 1.95 times as long as wide, gap between medial and submedial lobes slightly longer than wide. Spermathecae subspherical, with straight, slender sclerotized neck and large cylindrical basal apodeme.  
 Distribution. Costa Rica. The holotype was collected at 2500 m elevation.   
 Type data. Holotype ♀ (INBio INBio001111275), COSTA RICA: Heredia: Parque Nacional Braulio Carrillo, Estación Barva, LN 233400 523200, 2500 m, Jun 1990, A. Fernandez.   
 Etymology. The name of this species is a noun in the genitive case named for Mike Nolte, the brother of Matt Nolte, a student at Cornell College who helped us to score and homologize wing pattern characters.
