Type material. Holotype ♂, Colombia: Antioquia: Puerto Berrío, Alto de las Águilas, Hacienda Manaos, 6°27’10.09’’ N ̄ 74°36’13.74’’ W, 440 m, 06.VII ~ 07.VII.2013, Wolff-INPA, white light trap, 18:00̄19:00 [Forewing length, 10.1 mm; Hindwing length, 9.4 mm] (CEUA). Paratypes: Colombia: Antioquia: Puerto Berrío, Alto de las Águilas, Hacienda Manaos, 6°27’10.09’’ N ̄ 74°36’13.74’’ W, 440 m, 06‒07.VII.2013, Wolff- INPA, light trap, 18:00‒19:00 (1 ♀ ̄ CEUA); Sucre: Colosó, Montes de María, II.2012, J. Noriega, light trap in forest (2 ♀ — ANDES-E).
Holotype condition: good, pinned, with right wings extended, abdomen dissected and stored in a microvial with glycerin below the specimen.
Diagnosis. Body coloration pattern consisting in a mixture of dark brown and light yellow, wing membrane entirely hyaline. Male abdomen bearing two patches of 30̄55 circular pores laterally, on each side close to the anterior margin of tergite 5. Intersegmental membrane between tergites 5 and 6 invaginated, forming a bilobed pocket extended anteriorly 1/5 the length of the tergite 5. Ectoproct ovoid, rounded at apex. Sternite 9 subpentagonal in ventral view, with apex broadly rounded. Hypomeres elongated, shorter than pseudopenis, apex slightly clavate. Female terminalia with sternite 8 as long medially as laterally. Spermatheca with distal section slightly wider than medial section.
Description. Based on a pinned male and female, two females preserved in alcohol and the description by Hoffman (1992).
Head. Labrum dark brown, clypeus brown medially; mandibles dark amber; maxillary and labial palpi yellow to yellowish brown. Frons with a brown V-shaped inverted mark, medially with a pentagonal region light yellow in color (Fig. 4c). Scape light yellow anteriorly, brown posteriorly, pedicele brown, flagellum with 28̄33 articles covered with short and thick setae. Vertex mainly brown with yellow spots near compound eyes (Fig. 4c); postgena yellow (Fig. 4d). Compound eyes metallic brown.
Thorax. Prothorax 3.5̄ 5 mm long, straight in lateral view (Fig. 4b); pronotum light yellow or tan, with a brown longitudinal stripe at midline (Fig. 4d), prozona with two pairs of lateral brown spots, anterior margin brown, maculae brown (Fig. 4d); medial region laterally with two elongate brown spots (Fig. 2c); posterior portion with a brown spot. Mesonotum light yellow or tan to light brown, with two pairs of longitudinal brown stripes, scutellum with a V-shaped brown mark (Fig. 4d). Metanotum light brown with two lateral dark brown spots and light yellow at middle; scutellum with a V-shaped brown mark (Fig. 4d). Pteropleura mottled, sclerites mainly brown with some peripheral yellow regions (Fig. 4b).
Legs. Foreleg with coxa light brown, dorsal- and ventrally with longitudinal brown stripes; trochanter varying from light to dark brown. Femur 4‒5 mm long, light or dark brown at inner surface (Fig. 4f); sub-basal spine light to dark brown; outer surface yellow to light brown, with brown spots at base and apex, medial region with a brown spot adjacent to row of minor spines; with 30‒43 minor spines, basally yellow and brown at apex, (Figs. 4b, e). Tibia dorsally light to dark brown, ventrally with dark brown stripes. Tarsi brown. All segments covered with fine dark brown or yellow setae. Mid- and hindleg with coxa and trochanter light to dark brown, femur and tibia yellow to light brown, femur dark brown at base and apex, tibia basally dark brown. Tarsi light brown; tarsal claws brown with four apical teeth; arolium present. All segments covered with fine light or dark brown or yellow setae.
Wings. Forewing 10.1‒13 mm long, membrane hyaline, venation brown; costal space with six or seven crossveins. Pterostigma brown (Fig. 4a). Subcostal space hyaline to slightly infuscate, with four or five crossveins. RP with 5 or 6 branches, one branch arising from rarp1 (first radial cell), two or three leaving from rarp2 and rarp3 (second and third anterior radial cells). a2a3-1 with asperous region dark brown. A1 and base of A2 yellowish brown basally. Hindwing 9.4‒12 mm long, similar to forewing, membrane hyaline. Pterostigma brown. Principal veins brown, except base of Cu and anal veins that are yellow or light brown (Fig. 4a). Costal space with six or seven crossveins.
Abdomen. Tergites light brown, with brown stripe located on each sclerite on the posterior region. Sternites light brown, the first five with yellow margins, sternites of abdominal segments 6 and 7 dark brown. Pleura yellow to dark brown. Male pregenital abdominal apparatus: tergite 5 with anterolateral oval patches of 30‒55 circular pores. Intersegmental membrane between the abdominal segments 5 and 6 invaginated into a bilobed pocket extending anteriorly 1/5 the length of tergite 5 (Figs. 5a, c, d).
Male genitalia. Ectoproct brown, ovoid, with apex rounded, covered with long fine setae (Figs. 5a, b). Ventromedial lobe unsclerotized, directed medially, rounded at apex, with 20‒30 short and thick setae. Sternite 9 subpentagonal, apex broadly rounded in ventral view (Fig. 5i). Gonarcus median lobe wider than long, rounded at apex (Fig. 1h). Mediuncus widened at base in ventral view, apex forked (Fig. 1g). Gonocoxites slightly wider distally than basally, apex rounded and bent dorsolaterally. Pseudopenal membrane short. Hypomeres elongate, curved, shorter than pseudopenis, apex slightly knobbed (Fig. 5g). Pseudopenis sclerotized, curved dorsad in lateral view, pointed at apex, spine-like (Figs. 5g).
Female. Body color pattern, similar to that of male. Pronotum length, 4‒5 mm; forewing length 1 1‒13 mm, hindwing length, 10‒12 mm. Ectoproct ellipsoid (Figs. 6a, b), brown, covered with long yellow setae. Gonocoxite 9 ellipsoid (Figs. 6a, b), brown. Sternite 8 with a transverse brown stripe, posterior margin yellow to light brown, as long medially as laterally in ventral view (Figs. 6c, d). Spermatheca with medial section forming 1.5 coils wider than proximal section, distal section C-shaped, slightly wider than medial section (Figs. 6e, f). Fertilization canal duct shallowly curved at base, slightly sinuous distally (Figs. 6e, f).
Etymology. As a tribute to Kevin M. Hoffman, we decided to name this species using the same name he originally utilized in his dissertation, immaculata, meaning unspotted, which refers to the lack of an apical infuscation on the wings, a distinctive trait of this species. Feminine adjective.
Distribution. Colombia (Antioquia, Sucre), Panama (Hoffman 1992).
Comments. As in B. phthisica, this species has a camouflage-like coloration pattern, consisting in a mixture of yellow and brown, but the absence of green color on the body, and the lack of an apical infuscation on the wings easily separate both species. The arrangement of the pregenital abdominal apparatus is another important character to distinguish these species. In B. phthisica, pores on the tergite 5 are lacking, while there are two anterolateral patches of pores in B. immaculata. Male genitalia characters (such as morphology of ectoproct, gonocoxites, hypomeres, gornarcal membrane and mediuncus) and female genitalia traits (such as sternite 8 and spermatheca) are different as well.
