Head : head slightly wider than thorax; vertex 1/3 head width; gena 1/3 of head height, 2/5 of eye height. Fronto-orbital plate light brown-dark yellow in ground color, entirely covered with silver tomentum giving the whole plate a gold sheen transitioning to silver character; ocellar setae absent at most several hair-like setulae present on ocellar triangle; one reclinate orbital seta outside of frontal row; 1-3 small setae anterio to post-ocular setae; two rows of frontal setae, black setulae intermingled with setae, a few light colored yellow setulae extending below lowest frontal seta. Parafacial light yellow in ground color, densely covered in silver tomentum making the entire surface reflective and brilliant gold appearance; bare overall, except for a small number of setulae extending just below lowest frontal setae; facial ridge setose along 1/2-2/3 of its length, with a few sparse hair-like setulae emerging along outer edge of row; gena covered in yellow to reddish yellow setulae. Antenna, pedicel ranging from light brown to dark burnt orange, concolorous with postpedicel; postpedicel burnt orange, 4X as long as pedicel; arista bare distinctly-thickened on basal 4/5 almost to tip. Palps, yellow-orange throughout and densely covered in short black setulae; slightly clubbed, but gradually tapering to a slight point apically. Thorax : black ground color, with light gray tomentum throughout, when viewed dorsally tomentum appears thinner postsuturally; scutellum appearing reddish-black to the naked eye, under microscope reddish tomentum becomes apparent when view on an oblique caudal angle; scutum with four dorsal vittae, becoming more evident under certain angles of light, these broken at suture; lateral surface of thorax densely covered in long hair-like setulae, these setulae mostly black on proepimeron, and dorsal half of katepisternum with a few intermingled reddish-yellow hair-like setulae, these turning to mostly reddish yellow on anterior and caudal margin of anepisternum, katepimeron and anepimeron bearing mostly yellow setulae sometimes with a few black setulae; meron with a few yellow setulae intermingled with upper meral setae; chaetotaxy: 3-4 strong setae on postpronotum arranged in a line, acrostichal setae 3:3; dorsocentral setae 3-4:4; intra-alar setae 3:3; supra-alar setae 2:3; 4-5 katepisternal setae; scutellum, with 4-5 pairs of long flat marginal setae of subequal length; apical setae present, short straight and erect, at a slight upward angle from the plane of the rest of the scutellar marginal setae; complete row of scutellar discal setae just posterior to marginal setae. Wing : strongly infuscate, slightly orange at wing base, with a brilliant orange basicosta; 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 stalk with dark black/brown capitulum. Legs : black overall, coxa on midleg and hindleg with a few reddish-yellow setulae; tarsal claws yellow with black tips, with yellow pulvilli 2/3 length of tarsal claws; anterodorsal row of setae on hind tibia irregularly sized not fringelike. Abdomen : globose, with black ground color; abdominal tomentosity dark bronze and sparse on T3 confined to lateral areas, just under resting wings, sparse bronze-gold tomentum along at most 30% of surface of T4 bisected medially by an area devoid of tomentum, densely gold tomentose on 95% of surface of T5 bisected medially by a dorsomedial narrow darkened strip; middorsal depression on ST1+2 reaching to hind margin of tergite, ventrobasally ST1+2 bearing a few light yellow setulae similar to those on thorax; median marginal setae present on ST1+2 and T3, and complete rows of setae on T4 and T5. Male terminalia (Fig. 11 ): sternite 5 with a deeply excavated median cleft along posterior edge, smoothly U-shaped, margins covered in dense tomentum; posterior lobes coming to a rounded point apically, with strong bristle-like setulae surrounded by many shorter weaker setulae. Anterior plate of sternite 5 approximately 1/2 length of posterior lobes; unsclerotized "window" on anterior plate of sternite 5 ranging translucent directly basal to posterior lobes, elongate spanning the entire width of the posterior lobes. Cerci in posterior view triangular/blade-like in appearance, subequal to length of surstyli; completely separate medially. Cerci in lateral view. wide and appearing rounded apically, straight along lower margin with only a very slight anterior projection, not appearing clubbed apically; cerci setose along basal 2/3rds, underside of cerci setose along entire length (visible in lateral profile). Surstylus in lateral view, broadly rounded along its posterior edge giving the structure a leaf or oarlike appearance; surstylus appearing fused with epandrium; when viewed posteriorly surstyli appearing slightly convergent or bearing inward curved apices but not strongly convergent. Pregonite broad, well-developed, apically rounded, somewhat blunt, devoid of setulae. Postgonite, slightly narrowed, 1/3 as wide as pregonite, bluntly rounded with a slight curve at apex, short. Distiphallus broadly cone-shaped (in some species this cone or flare is much more pronounced, in others appearing square or barrel shaped), with a slender median longitudinal sclerotized reinforcement on its posterior surface and a broad, anterolateral, sclerotized acrophallus, on anterior surface near apex, ~1.6X as long as basiphallus; epiphallus, short and rounded, appearing as a small hump on dorsal surface of basiphallus. Female (Fig. 12 ) length: 11-12mm, overall morphology as in male differing in the following traits: Head : bearing 3-5 pairs of proclinate orbital setae in addition to single pair of reclinate orbital seta; gena 1/4 of eye height. Thorax : scutellum with up to 4-5 pairs marginal scutellar setae although most often similar to males. Abdomen : similar to males, differing only in terminalia. Diagnosis Belvosia angelhernandezi sp. n. can be distinguished from all other Belvosia by the following combination of traits: fronto-orbital plate and parafacial silver tomentose, pilosity of gena, and lowest frontal setulae reddish-yellow, basicosta brilliant orange, abdomen with dark ground color, median marginal setae present on syntergite 1+2, anterior margin of T3 bearing some no gold tomentum <10%; gold tomentum on T4 ranging from 20-40% coverage of tergite, T5 entirely gold tomentose, gold tomentum of tergites bissected medially by a middorsal stripe of dark tomentum. Etymology Belvosia angelhernandezi sp. n. , is named in honor of Sr. Angel Hernandez in recognition of his decades of being part of the Parataxonomist Program of Area de Conservacion Guanacaste (http://www.acguanacaste.ac.cr) in northwestern Costa Rica. Interim species-specific name included in previously circulating databases and publications, Belvosia Woodley03A. Distribution Costa Rica, ACG (Guanacaste Province), 290 m elevation. Ecology Belvosia angelhernandezi sp. n. has been reared 75 times from one species of Lepidoptera in the family Saturniidae , Hylesia umbrata (Schaus, 1911), in dry forest, dry-rain lowland intergrade.
