Description

Male (Fig. 78), length: 9-11mm. Head: head wider than thorax; vertex 1/3 head width; gena 1/3 of head height, 2/5 of eye height. Fronto-orbital plate silver tomentose throughout, darkening to gray appearing glabrous apically, with 2-3 irregular rows of frontal setae, populated with short black hair-like setulae intermingled with setae; ocellar setae absent; 1 pair of slightly inwardly lateroclinate orbital setae present outside frontal row. Parafacial light yellow in ground color, densely covered in same silver tomentum as on fronto-orbital plate, entire surface reflective and brilliant appearance; almost bare along parafacial outside facial ridge, with a few reddish-yellow setulae intermingled with facial ridge setae and extending just below lowest frontal setae; facial ridge setose along 2/3 of its length; gena covered in yellow setulae. Antenna, pedicel appearing dark brown or black, overall concolorous with postpedicel; postpedicel dark brown almost black, 3-4X as long as pedicel; arista bare gradually tapering to a point at tip. Palps, burnt umber dark yellow throughout and densely covered in short black setulae; tapering to a sharp point apically, slightly clubbed, devoid of setulae apically. Vibrissa approximately 1 pedicel length from facial margin. Thorax: black ground color, with light pale-gray tomentum throughout, appearing glabrous to the naked eye; scutellum ground color light brown, distinctly lighter than scutum, under microscope bronze tomentum throughout becomes visible; scutum with four narrow dorsal vittae, one outer pair, one inner pair, both broken at suture, inner pair extending only slightly beyond first post-sutural dorsocentral seta; lateral surface of thorax densely covered in long hair-like setulae, these setulae all black; chaetotaxy: 3 strong setae on postpronotum arranged in a line, acrostichal setae 3:3; dorsocentral setae 3:4; intra-alar setae 3:3; supra-alar setae 2:3; 4 katepisternal setae; scutellum, with 4-5 pairs of long marginal setae of subequal length; apical scutellar setae short erect, inserted slightly above plane of marginal setae; 1 complete row of scutellar discal setae just posterior to marginal setae. Wing: infuscate, slightly darkened yellow/orange at wing base, basicosta mostly dark brown with only slight orange present along caudal margin; both upper and lower calypters also infuscate concolorous with remainder of wing; wing vein R4+5 setose, bearing only 2-3 setulae at base; halteres orange. Legs: black overall, lightly covered in shimmering bronze tomentum, posterior margin of coxa on midleg and hindleg covered in yellow setulae; tarsal claws yellow-orange with black tips, with burnt umber pulvilli shorter than length of tarsal claws; anterodorsal row of setae on hind tibia irregular and not fringelike, with several longer stronger setae at least 2X as long as others. Abdomen: small and rounded globose, black to dark burgundy ground color; tomentum absent from T1+2, light dusting of bronze tomentum on T3 with only very slight gold tomentum along anterior margin, dark bronze tomentum covering anterior 70-80% of surface of T4, bisected medially by an area devoid of tomentum, in some cases this bronze can appear as subdued gold under different angles of light, brilliant gold tomentose throughout T5 reaching to hind margin of tergite; ventral surfaces of T3-T5 extremely densely hirsute but with no distinct sex-patches present, with light gold tomentum throughout; middorsal depression on ST1+2 reaching to hind margin of tergite; ST1+2 with 1 pair of median marginal setae, pairs of median marginal setae present on T3, and complete rows of setae on T4 and T5.

Male terminalia (Fig. 79): sternite 5 with a deeply excavated wide median cleft along posterior edge, roughly U-shaped, margins covered in dense tomentum; posterior lobes rounded apically, with a group of strong setulae surrounded by many shorter weaker setulae. Anterior plate of sternite 5 approximately 2/3 length of posterior lobes; unsclerotized "window" on anterior plate of sternite 5 elongate, translucent, rectangular, slightly upturned at extremities. Cerci in posterior view triangular, equal to length of surstyli; pointed at apex, medially to fused along basal 2/3 of their length. Cerci in lateral view, inflated along basal 1/3rd, sharply tapered sinsusoid curved at apical 1/3, giving it a shallow wavy appearance; cerci setose along basal 2/3rds, underside of cerci setose along basal 2/3 of length. Surstylus in lateral view, pointed apically, straight slightly arcuate along inferior margin, and curved along superior margin, scimitar-like in appearance; surstylus appearing not fused with epandrium; when viewed posteriorly surstyli straight not convergent. Pregonite broad, well-developed, apically rounded off, and blunt, with 5-6 marginal setulae. Postgonite, narrow, 1/2 as wide as pregonite, sharply pointed and curved at apex, bladelike, postgonite subequal in length to pregonite. Distiphallus broadly cone-shaped, with a slender median longitudinal sclerotized reinforcement on its posterior surface and a broad, epiphallus appearing as a narrow raised, hooked protuberance, at base of distiphallus, sclerotized acrophallus, blunt and bulbous near apex, 1.2X length of basiphallus.

Female (Fig. 80) length: 9-11mm, overall morphology as in male differing in the following traits: Head: bearing 1-2 rows of frontal setae and 3-4 pairs of proclinate orbital setae in addition to single pair of reclinate orbital seta. Abdomen: dark bronze tomentum covering anterior 70-80% of surface of T4, bisected medially by an area devoid of tomentum, visible as subdued gold under different angles of light and all of T5, much denser than in males; T4 bearing a narrow median black stripe bisecting yellow band; slightly more globose than males.

Diagnosis

Belvosia osvaldoespinozai sp. n. can be distinguished from all other Belvosia by the following combination of traits: yellow setulae on gena, frotoorbital plate silver, black basicosta, and T5 entirely gold tomentose.

Etymology

Belvosia osvaldoespinozai sp. n, is named in honor of Sr. Osvaldo Espinoza in recognition of his decades of being part of the Parataxonomist Program of Area de Conservación Guanacaste (http://www.acguanacaste.ac.cr) in northwestern Costa Rica ( Janzen and Hallwachs 2011). Interim species-specific name included in previously circulating databases and publications, Belvosia Woodley14.

Distribution

Costa Rica, ACG, Alajuela and Guanacaste Provinces, 320-1000m elevation.

Ecology

Belvosia osvaldoespinozai sp. n. has been reared 27 times from four species of Lepidoptera in the family Erebidae , Ochrodota marina Schaus, 1910 (N=1), Ochrodota marina DHJ01 (N=3), Ochrodota marina DHJ02 (N=20), Ochrodota pronapides BE03 (N=3), in cloud forest, rain forest and dry-rain lowland intergrade.
