Description

Male (Fig. 95), length: 10mm. Head: head slightly wider to 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 1-2 rows of frontal setae, 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 bright orange appearing, overall in contrast with postpedicel; postpedicel dark brown almost black, 3.5X 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, colorshifting to gold tomentum on posterior half only evident when viewed from posterior angle; scutellum ground color light brown almost yellow, 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. Wing: infuscate, slightly darkened gray at wing base, basicosta 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 not regular or fringelike, with several longer stronger setae at least 2X as long as others. Abdomen: small and rounded globose, black to dark burgundy ground color; tomentum absent from T1+2, with gold tomentum on over 60% of surfaces of both T3 and T4, both with a section of black tomentum along the midline of the tergite, appearing as a black gap between 4 gold patches, T5 entirely gold tomentose; ventral surfaces of T3-T5 extremely densely hirsute but with no distinct sex-patches present, with light gold almost silver tomentum throughout; middorsal depression on ST1+2 reaching to hind margin of tergite; ST1+2 and T3 lacking median marginal setae, and complete rows of median marginal setae on T4-T5.

Male terminalia (Fig. 96): sternite 5 with an excavated median cleft along posterior edge, smoothly U-shaped, margins covered in dense tomentum; posterior lobes squared off apically, with strong erect bristle-like setulae surrounded by many shorter weaker setulae. Anterior plate of sternite 5 approximately subequal to length of posterior lobes; unsclerotized "window" on anterior plate of sternite 5 translucent directly basal to posterior lobes, flat basally, with 3 indentations along anterior edge. Cerci in posterior view triangular, short subequal to length of surstyli; separate medially along apical 2/3s of its length. Cerci in lateral view. narrow 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 bare. Surstylus in lateral view, wide broadly rounded, spatulate 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 short, not well-developed, apically flat, somewhat blunt, devoid of setulae. Postgonite, short slightly narrowed, 1/3 as wide as pregonite, hooked and sharp at apex. Distiphallus broadly cone-shaped and a broad, anterolateral, sclerotized acrophallus, on anterior surface near apex, 1.4X length of basiphallus.

Female (Fig. 97) length: 9-11mm, overall morphology as in male differing in the following traits: Head: bearing 1-2 rows of frontal setae and 3-4 pairs of proclinate orbital setae in addition to single pair of reclinate orbital seta. Abdomen: abdomen slightly more globose than males.

Diagnosis

Belvosia ruthfrancoae sp. n. can be distinguished from all other Belvosia by the following combination of traits: dark setulae below lowest frontal setae, and on gena, orange basicosta, calypters infuscate brown, and median marginal setae absent from ST1+2 and T3.

Etymology

Belvosia ruthfrancoae sp. n, is named in honor of Srta. Ruth Franco, in recognition of her 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 Woodley20.

Distribution

Costa Rica, ACG, Guanacaste Province, 295m elevation.

Ecology

Belvosia ruthfrancoae sp. n. has been reared four times from one species of Lepidoptera in the family Notodontidae , Ianassa drucei DHJ04 (N=4) in dry forest.
