( Figs. 3 , 63–64 , 318 , Map 4)

Diagnosis.— Barbaloba jubae is similar to B. meleagrisellae in facies but differs from the latter by having a broader uncus; and a more densely packed cluster of tergal setae of the tegumen. B. jubae also has a tuft of piliform sex scales originating from an area slightly beyond base of the frenulum above a swollen bulla of the hindwing; a tuft with outwardly curved sex scales originating from the base of the anal fold of the hindwing; an apical process of ventral part of valva curved near 2/3; a mesially emarginate ventroposterior margin of the gnathos; a setose, angular plate overlying the dorsal articulation of the dorsal part of the valva; a basal ridge of the digitate process extending ventrolaterally, forming a densely setose lobe; a lobe from the middle of the dorsal part of valva, extending ventrally, bearing a densely packed cluster of spinelike setae on the apical part; a divided juxta; and a shallowly curved phallus and sclerite of phallus from 2/3 that are lacking in B. meleagrisellae .

Description.—Head: Vertex, frontoclypeus dark brown [pale brown on worn specimens]. Outer and inner surfaces of labial palpus dark brown or brown intermixed with pale-brown scales near apical margins of segments 1–2, terminal segment pale brown apically. Antennal scape, pecten and flagellum dark brown; first flagellomere unmodified in male. Proboscis dark brown.

Thorax: Tegula, mesonotum, and legs pale brown. Forewing ( Fig. 318 ): Length 5.6–6.0 mm (n = 7), pale brown intermixed with brownish-gray scales. Undersurface brown. Venation ( Fig. 3 ) with R4 and R5 curved to costa, M3 and CuA1 separate, and CuA2 acutely curved basally. Hindwing: Pale brown, with two tufts of sex scales; one gray tuft of piliform scales originating from area slightly beyond base of frenulum above a swollen bulla, each scale extending beyond middle; bulla overlaid by imbricate scales; a second pale-brown tuft with outwardly curved scales originating from base of anal fold. Venation ( Fig. 3 ) with crossvein of cell weak, cubitus 3-branched with CuA1 absent and M2+M3 slightly longer than CuA2.

Abdomen: Male genitalia ( Figs. 63–64 ): Uncus gradually narrowed from widely rounded base, forming sparsely setose, narrowly rounded, apical lobe; lobe longer than width of anal opening. Dorsal strut absent. Gnathos, a thin band confluent with tegumen, mesially protuberant, narrowly emarginate lobe. Sockets of tergal setae not extending beyond 1/2 length of tegumen. Distance between articulations of tegumen and vinculum shorter than length of valva. Valva divided, ventral part of valva broadly rounded basally, abruptly narrowed, forming elongate spinelike process; process inwardly curved near 2/3; ventral margin setose on lateral part; margin greatly upturned, forming widened fold, extending to base of apical process; dorsal part of valva with costa developed distolaterally, forming sparsely setose digitate process; dorsal articulation overlaid by angular, setose plate; plate with serrate dorsal margin; basal ridge of digitate process extending ventrolaterally, forming densely setose lobe; lobe with deeply crenulate margin; a second larger lobe beneath, arising from middle, extending ventrally, with densely packed cluster of spinelike setae on apical 1/3. Juxta divided mesially forming two angular plates. Phallus and sclerite of phallus shallowly curved near 2/3; anellus parallelsided from a broadened base, broadly rounded apically, setose. Female Genitalia: Unknown.

Distribution (Map 4). Barbaloba jubae is known from one collecting site near the western most part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet, jubae is derived from the Latin word for mane, and refers to the setose lobelike process originating from the ventral part of the valva of the male genitalia.
