Description

Male (Fig. 98), length: 12mm. Head: head slightly wider to thorax; vertex 1/3 head width; gena 1/4 of head height, 1/3 of eye height. Fronto-orbital plate silver tomentose throughout, darkening slightly apically, 2 rows of frontal setae, orbital setae absent. 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 4/5 of its length; gena covered in black setulae. Antenna, pedicel bright orange appearing, overall in contrast with postpedicel; postpedicel dark brown almost black, 4-5X 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, tomentum receding along posterior edge, postallar callosity with a light vestiture of bronze tomentum only visible on certain angles; scutellum ground color dark reddish-brown, distinctly lighter than scutum, under microscope bronze tomentum throughout becomes visible; scutum with four distinct dorsal vittae, one outer pair, one inner pair, both broken at suture; 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, these setae 1/2-2/3 length of scutellar marginals. Wing: infuscate, slightly darkened gray at wing base, basicosta brilliant 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, fringelike. Abdomen: small and rounded globose, orange-brown ground color; gold tomentum absent from T1+2-T4, but present on over 90% of surface of T5; ventral surfaces of T3-T5 extremely densely hirsute with distinct sex-patches present; middorsal depression on ST1+2 reaching to hind margin of tergite; ST1+2 and T3 with one pair of median marginal setae, and complete rows of median marginal setae on T4-T5.

Male Terminalia: (Fig. 99) Sternite 5 with a deeply excavated median cleft along posterior edge, smoothly U-shaped, margins with a slight shoulder, covered in dense tomentum; posterior lobes rounded apically, with long 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 translucent, elongate spanning almost the entire width of the posterior lobes rectangular in shape. Cerci in posterior view triangular, subequal to length of surstyli; separate medially halfway along its length. 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. Surstylus in lateral view, broadly rounded along its posterior edge giving the structure a blade-like appearance; surstylus appearing fused with epandrium; when viewed posteriorly surstyli appearing straight with no apparent bias. Pregonite broad, well-developed, apically rounded, somewhat blunt, devoid of setulae. Postgonite, narrower than pregonite, rounded with a slight curve at apex. 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, ~1.9X as long as basiphallus.

Female: unknown at this time.

Diagnosis

Belvosia sergioriosi sp. n. can be distinguished from all other Belvosia by the following combination of traits: gena covered in black setulae, orange basicosta, median marginal setae present on ST1+2, and T4 lacking any gold tomentum. It can be differenciated from its closest congener B. naccina by the color of the arista, and the evenly infuscate wings.

Etymology

Belvosia sergioriosi sp. n, is named in honor of Sr. Sergio Rios 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 Woodley21.

Distribution

Costa Rica, ACG, Guanacaste Province, 380m elevation.

Ecology

Belvosia sergioriosi sp. n. has been reared once from one species of Lepidoptera in the family Saturniidae , Pseudodirphia regia Draudt, 1930 (N=1) in rain forest.
