Description

Male (Fig. 10), length: 11-12mm. 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 Conservación 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.
