Diagnosis.— Barbaloba meleagrisellae is similar to B. jubae in facies but differs from the latter by having a narrower uncus; fewer tergal setae of the tegumen. B. meleagrisellae also has an acutely curved (from 1/3) apical process of the ventral part of the valva; an anteriorly directed and entire posteroventral margin of the gnathos; a densely microtrichiate region near base of the dorsal part the of valva; a laterally projecting lobe with a densely packed cluster of long, inwardly curved setae originating from the base of dorsal part of valva; a bandlike juxta; and a broadly curved phallus and sclerite of phallus that are lacking in B. jubae .

Description.—Head: Scales on vertex and frontoclypeus brown tipped with pale brown. Outer surface of labial palpus dark brown intermixed with pale-brown scales, segments 1–2 pale brown along apical margins; terminal segment with basal 2/3 dark brown, apical 1/3 pale brown; inner surface of labial palpus paler. Antennal scape brown intermixed with pale-brown scales along apical margin, pecten pale brown, flagellum brown; first flagellomere unmodified in male. Proboscis pale brown.

Thorax: Tegula with basal 1/3 dark brown, apical 2/3 pale brown; mesonotum pale brown. Legs brown intermixed with pale-brown scales near midsegments and along apical margins of all segments and tarsomeres. Forewing ( Fig. 317 ): Length 5.1 mm (n = 1), pale brown intermixed with dark-brown scales and few brownishorange scales; basal 1/3 mostly pale brown, apical 2/3 slightly darker (with more brownish-orange and dark-brown scales); submedian fascia dark brown, complete; cell with three dark-brown spots, one spot near middle (combined with submedian fascia), and two spots on apical end along crossvein; marginal spots faint. Undersurface brown. Hindwing: Translucent pale brown.

Abdomen: Male genitalia ( Figs. 61–62 ): Uncus wide basally, narrowed near 1/3, forming parallelsided, ventrally curved, sparsely setose, apical part; apical part longer than width of anal opening. Dorsal strut absent. Gnathos, a anteriorly directed thin band confluent with tegumen. Sockets of tergal setae not extending beyond 1/2 lateral length of tegumen. Distance between articulations of tegumen and vinculum shorter than length of valva. Valva divided, ventral part of valva broadly rounded basally, gradually narrowed, forming inwardly curved spinelike process; process acutely curved from 1/3, with planate inner surface, setose on outer surface; ventral margin upwardly curved, forming round fold beneath dorsal part, terminating near setose ridge at base of apical process; dorsal part with apical portion of costa developed distolaterally, forming sparsely setose, digitate process; basal ridge of digitate process extending ventrally fusing with basal part; basal part densely microtrichiate, developed ventrally into elongate, laterally projecting lobe; lobe with densely packed cluster of elongate, inwardly curved setae. Proximal flange absent. Juxta bandlike. Phallus and sclerite of phallus broadly curved from midlength; anellus parallelsided from wide base, broadly rounded apically, setose on apical 2/3. Female Genitalia: Unknown.

Distribution (Map 3). Barbaloba meleagrisellae is known from one collecting site on the western part of the Cordillera de Guanacaste in northwestern Costa Rica.

Etymology. The specific epithet, meleagrisellae is derived from the Greek Meleagris , the genus that includes the turkey, a bird in which males have a beardlike process on the anterior part of the breast, and refers to the setose lobelike process originating from the ventral part of the valva of the male genitalia.
