Description

Male (Fig. 49), length: 11-13mm. 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 black in ground color, lightly covered with gray tomentum giving majority of the plate a glabrous dark gray sheen transitioning to silver; ocellar setae absent at most several hair-like setulae present on ocellar triangle; reclinate orbital seta absent; two rows of frontal setae, black setulae intermingled with setae. Parafacial dark yellow in ground color, densely covered in silver tomentum making the entire surface reflective brilliant silver appearance; bare overall, except for a small number of setulae extending just below lowest frontal setae; facial ridge setose along 1/3-1/2 of its length, with a few sparse hair-like setulae emerging along outer edge of row; gena covered in black setulae. Antenna, pedicel black, concolorous with postpedicel; postpedicel, 1.5X as long as pedicel; arista bare gradually tapered. 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, some bronze tomentum on the postalar callosity; scutellum appearing glabrous reddish-black to the naked eye, under microscope bronze 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 black hair-like setulae; chaetotaxy: 3-4 strong setae on postpronotum arranged in a line, acrostichal setae 3:4-6 often with 2 extra setae appearing just adjacent to acrostichal setae; dorsocentral setae 3:4; intra-alar setae 3:3; supra-alar setae 2:3; 4-6 katepisternal setae; scutellum, with 5-6 pairs of long flat marginal setae of subequal length; apical setae absent; complete row of scutellar discal setae just posterior to marginal setae. Wing: strongly infuscate, slightly orange at wing base, black basicosta, with some orange along posterior 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 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 fringelike, formed by a very regular row of uniformly sized setae separated from each other by less than the width of their socket. Abdomen: globose, with dark burgundy-black ground color; abdominal tomentosity on T1+2-T3 bronze, confined to the anterior margin of the tergite, at most anterior 10% of surface, T4 with gold tomentum over anterior 1/3 of the surface, T5 densely gold tomentose on 90% of surface absent along posterior 10%, which appears as glabrous black; middorsal depression on ST1+2 reaching to hind margin of tergite, median marginal setae present on ST1+2 wide set, stout but short, approximately 1/2 as long as median marginals on T3, T3 also with 1 pair of median marginal setae, very strongly appressed to abdomen, and complete rows of marginal setae on T4 and T5; ventral surfaces of T3-T4 with clearly defined sex-patches extending from underside of tergite to lateral surface.

Male terminalia (Fig. 50): sternite 5 with a deeply excavated median cleft along posterior edge, Y-shaped, margins covered in dense tomentum; posterior lobes rounded apically, with multiple strong setulae surrounded by many shorter weaker hair-like setulae. Anterior plate of sternite 5, 1/2 as long as posterior lobes; unsclerotized "window" on anterior plate of sternite 5 translucent directly basal to posterior lobes, rectangular shaped, with a slight bow to basal edge. Cerci in posterior view broadly triangular, longer than surstyli; blunt and rounded at apex, fused medially along 1/2 of their length. Cerci in lateral view, with a strong anterior curve arc beginning on anterior 1/3 to apex; cerci densely setose along basal 2/3rds, setae becoming 2x as long on basal 1/2. Surstylus in lateral view, almost equilateral along appearing digitiform rounded apically; surstylus appearing to be separate and not fused with epandrium; when viewed posteriorly surstyli slightly convergent. Pregonite usually broad, well-developed, apically squared off or rounded, usually blunt, basally setulose. Postgonite, slightly narrowed, 1/3 as wide as pregonite, sharply pointed and curved at apex, typically short and scythelike, with few exceptions where postgonite is subequal in length to pregonite. 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.

Female (Fig. 51) length: 11-13mm, overall morphology as in male differing in the following traits: Head: fronto-orbital plate dull gray, sometimes appearing devoid of tomentum along vertex, bearing 3-4 pairs of proclinate orbital setae in addition to 1-2 pairs of reclinate orbital seta; profile of head not rounded as in males. Thorax: Thoracic chaetotaxy: acrostichal setae 3:4; dorsocentral setae 3:4; intra-alar setae 2:3; supra-alar setae 2:3. Abdomen: more globose than males, lacking the flattened character, setulae on abdomen not as dense appearing far less hirsute than male abdomen; differing in terminalia, and T3 bearing goldish tomentum on ventral surface.

Diagnosis

Belvosia guillermopereirai sp. n. can be distinguished from all other Belvosia by the following combination of traits: gena covered in black setulae, black basicosta, both calypters dark, anterodorsal setae on hind tibia comblike and regular, and T5 black apically, sex patch present; male terminalia: epandrium densely hirsute, surstyli digitiform and apically rounded, subequal to length of cerci.

Etymology

Belvosia guillermopereirai sp. n, is named in honor of Sr. Guillermo Pereira 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 Woodley07C.

Distribution

Costa Rica, ACG, Alajuela and Guanacaste Provinces, 10-620m elevation

Ecology

Belvosia guillermopereirai sp. n. has been reared 34 times from six species of Lepidoptera in the family Sphingidae , Erinnyis alope (Drury, 1773) (N=4), E. ello (Linnaeus, 1758) (N=2), E. oenotrus (Cramer, 1780) (N=1), Pachylia ficus (Linnaeus, 1758) (N=11), P. syces ( Hübner, 1819) (N=15), Xylophanes chiron (Drury, 1773) (N=1) in dry foresrt, rain forest, and dry-rain lowland intergrade.
