Description

Male (Fig. 16), length: 9-12mm. Head: head slightly wider than thorax; vertex 1/3 head width; gena 1/5 of head height, 1/4 of eye height. Fronto-orbital plate ranging from dull silver or pale gray to less often slightly greenish gold with gold tomentum at most on upper 2/3, with three rows of frontal setae, black hair-like setulae intermingled with setae, with a few light colored yellow setulae extending below lowest frontal seta; ocellar setae absent at most several hair-like setulae present on ocellar triangle; row of 2-10 short strong setae directly anterior to post-ocular row; one slightly inwardly lateroclinate-reclinate orbital seta outside of frontal row; 2-3 rows of frontal setae, black setulae intermingled with setae, and 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 appearance; setulose along parafacial outside facial ridge, a small number of setulae extending just below lowest frontal setae; facial ridge setose along 2/3-4/5 of its length, with numerous yellow-yellow hair-like setulae emerging along outer edge of row; gena covered in yellow setulae. Antenna, pedicel burnt orange, contrasting with postpedicel; postpedicel black, 3X as long as pedicel; arista bare gradually tapering to a point at tip. Palps, yellow-orange throughout and densely covered in short black setulae; only slightly clubbed, tapering to a slight point apically, devoid of setulae apically. Thorax: black ground color, with light gray tomentum throughout, when viewed dorsally tomentum appears dense and silver postsuturally; scutellum appearing dark brown-black to the naked eye, under microscope dense bronze tomentum becomes apparent when view on an oblique caudal angle; scutum with four dorsal vittae, one outer pair, one inner pair broken at suture; lateral surface of thorax densely covered in long hair-like setulae, these setulae mostly reddish, caudal half of anepimeron densely covered in long black setulae, these turning to mostly reddish yellow on anterior and caudal margin of anepisternum, remainder of surfaces with dense long reddish-yellow setuale and with a few yellow setulae intermingled with upper meral setae; chaetotaxy: 3 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; 1 complete row of scutellar discal setae just posterior to marginal setae. Wing: strongly infuscate, slightly darkened but not 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 orange pulvilli subequal to length of tarsal claws; anterodorsal row of setae on hind tibia irregularly sized not fringelike. Abdomen: globose, with black ground color, orange lateroventrally on ST1+2-T4; bronze to gold tomentosity along anterior 10% of T3, gold tomentum along anterior 80% of surface of T4 bisected medially by an area devoid of tomentum, densely gold tomentose throughout T5 reaching to hind margin of tergite; sparse silver tomentum present ventrally, along tergal margins; 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. 17): sternite 5 with a deeply excavated median cleft along posterior edge, deep and Y-shaped, margins covered in dense tomentum; posterior lobes, bare and rounded apically, tapering and becoming hirsute with tomentum basally, with multiple bristle-like setulae. Anterior plate of sternite 5, 1/2 length of posterior lobes; unsclerotized "window" on anterior plate of sternite 5, directly basal to posterior lobes, elongate and sinuous, vaguely "w" shaped, spanning almost the entire width of the sternite. Cerci in posterior view triangular, slightly shorter than surstyli; rounded at apex yet slightly pointed, fused along most of their length, only separating along anterior 1/4. Cerci rounded/blunt in lateral view with a very slight anterior curve on apex, giving it a slightly clubbed appearance; cerci densely setose along basal 2/3rds, underside of cerci setose along entire length. Surstylus in lateral view, scythelike ending in a slightly downcurved and tapered apex making the structure appear bladelike; surstylus appearing fused with epandrium; when viewed posteriorly surstyli slightly divergent or with a slight outward curved at apices. Pregonite broad, well-developed, apically squared off or rounded, blunt, devoid of setulae, marginally thickened, heavily sclerotized. Postgonite, slightly narrowed, 1/3 as wide as pregonite, blunt and curved at apex, subequal in length to pregonite. Epiphallus well developed and apically hooked. Distiphallus apically flared, 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, ~1.7X as long as basiphallus.

Female (Fig. 18) length: 9-13mm, overall morphology as in male differing in the following traits: Head: fronto-orbital plate only dull gray, sometimes appearing devoid of tomentum, bearing 3 pairs of proclinate orbital setae in addition to single pair of reclinate orbital seta. Thorax: hair-like setulae of anepisternum entirely black. Abdomen: as in the males differing only in terminalia.

Diagnosis

Belvosia calixtomoragai sp. n. can be distinguished from all other Belvosia by the following combination of traits: fronto-orbital with dull gray or silver tomentum (sometimes tomentosity can be sparse as to make the fronto-orbital plate appear yellow, but distinctly not gold) and silver parafacial, pilosity of gena, and lowest frontal setulae yellow, setulae below lowest frontal seta pale yellow, basicosta brilliant orange; pilosity of katepisternum, meron and anepimeron, with mostly black setulae, thorax with only three postsutural acrostichals; abdomen with dark ground color, median marginal setae present on syntergite 1+2, gold tomentum on T4 ranging from covering more than 50% of tergite.

Etymology

Belvosia calixtomoragai sp. n, is named in honor of Sr. Calixto 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 Woodley03C.

Distribution

Costa Rica, ACG (Provinces of Alajuela and Guanacaste), 95-1150m elevation.

Ecology

Belvosia calixtomoragai sp. n. has been reared 33 times from five species of Lepidoptera in the family Saturniidae , Hylesia continua (Walker, 1865) (N=24), H. dalina Schaus, 1911 (N=1), H. Janzen22 (N=4), H. lineata Schaus, 1911 (N=3), H. rubrifrons Druce, 1886 (N=2), in rain forest, dry forest, and dry-rain lowland intergrade.
