Description

Male (Fig. 93), length: 12-13mm. Head: head wider than thorax; vertex 1/3 head width; gena 1/3 of head height, 1/2 of eye height. Fronto-orbital plate silver tomentose throughout, darkening slightly apically in some cases appearing slightly glabrous apically, with one row of frontal setae, and a second broken row somewhat apparent, and 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 several black setulae intermingled with facial ridge setae and extending just below lowest frontal setae; facial ridge setose along 2/3-4/5 of its length; gena covered in black setulae. Antenna, pedicel darkened appearing dark brown or black, overall concolorous with postpedicel covered in a silver sheen; postpedicel dark brown almost black, 2.5X as long as pedicel; arista bare gradually tapering to a point at tip. Palps, orange throughout and densely covered in short black setulae; tapering to a sharp point apically, devoid of setulae apically. Vibrissa approximately 1 pedicel length from facial margin. Thorax: black ground color throughout, with gray tomentum throughout; scutellum ground color light brown almost yellow, distinctly lighter than scutum, under microscope bronze tomentum throughout becomes visible; scutum with five dorsal vittae, one outer pair, one inner pair, both broken at suture, and one dorsocentral vitta appearing postsuturally; lateral surface of thorax densely covered in long hair-like setulae, these setulae all black; chaetotaxy: 3-4 strong setae on postpronotum arranged in a line, acrostichal setae 3:3-4; 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 dark brown with orange; 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, 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 regular and fringelike, with one longer stronger setae at least 2X as long as others. Abdomen: large and slightly flattened globose, black to dark burgundy ground color; tomentum absent from T1+2-T4, with a very light almost invisible dusting of bronze tomentum on 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 2-4 pairs of median marginal setae, and complete rows of median marginal setae on T3-T5.

Male terminalia (Fig. 94): sternite 5 with a deeply excavated median cleft along posterior edge, smoothly 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 subequal to length of posterior lobes; unsclerotized "window" on anterior plate of sternite 5 absent. Cerci in posterior view triangular, slightly shorter than surstyli; blunted apex, medially to fused along 1/2 of their length. Cerci in lateral view, anterior curved at apex, giving it a shallow hooked appearance; cerci densely setose along basal 2/3rds, underside of cerci setose along basal 1/2 of length. Surstylus in lateral view, almost broad and equilateral along its length widening slightly slightly at apex structure appear spatulate; surstylus appearing to be fused with epandrium; when viewed posteriorly surstyli slightly convergent. Pregonite broad, well-developed, apically squared off, and blunt, devoid of setulae. Postgonite, slightly narrowed, 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, anterolateral, sclerotized acrophallus, on anterior surface near apex, 1.5X length of basiphallus.

Female: unknown at this time.

Diagnosis

Belvosia rostermoragai sp. n. can be distinguished from all other Belvosia by the following combination of traits: dark setulae below lowest frontal setae, black basicosta, ST1+2 with 2-4 pairs of median marginal setae, and complete rows of median marginal setae on T3-T5, and very light gold tomentum on T5.

Etymology

Belvosia rostermoragai sp. n, is named in honor of Sr. Roster Moraga 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 Woodley19.

Distribution

Costa Rica, ACG, Alajuela Province, 620-700m elevation.

Ecology

Belvosia rostermoragai sp. n. has been reared three times from one species of Lepidoptera in the family Saturniidae , Rothschildia triloba Rothschild, 1907 (N=3) in rain forest.
