Description

Male (Fig. 21). Length: 5-7 mm. Head (Fig. 21b): vertex 1/3 of head width; two reclinate upper orbital setae; ocellar setae arising slightly behind anterior ocellus; ocellar triangle gold, concolorous with fronto-orbital plate; fronto-orbital plate entirely gold and sparsely setulose throughout, setulae not reaching below lowest frontal seta; parafacial shiny silver and bare; facial ridge setose along its entire length; eye with short sparse ommatrichia up to 2X as long as one ommatidium; pedicel light brown; postpedicel black; arista brown, bare, distinctly thickened on basal 1/3-1/4; palpus dark amber yellow and haired. Thorax (Fig. 21a, c): pale brassy-silver tomentose dorsally, grey tomentose laterally; four prominent dorsal vittae, outermost two slightly broken across suture, innermost pair unbroken across suture, reaching 2nd postsutural dorsocentral seta; postpronotum with 3-4 setae arranged in a triangle; chaetotaxy: acrostichal setae 3:3; dorsocentral setae 3:4; intra-alar setae 3-4:3; supra-alar setae 2:3; three katepisternal setae; lateral scutellar setae shorter than subapical scutellar setae; apical scutellar setae curving inwards medially and slightly upturned so as to rise above the plane of remaining scutellar setae; one pair of discal scutellar setae; scutellum slightly darker and grey along basal 3/4, apically concolorous with scutum. Legs (Fig. 21c): femora and coxae black in ground colour; tibiae yellow in ground colour, densely covered in short black hairs, appearing darkened, almost black; fore femur with dense silver tomentum on posterodorsal surface; hind coxa with a single seta along posterior margin. Wing (Fig. 21a): pale translucent, hyaline, not distinctly infuscate; vein R4+5 with only two setulae at base. Abdomen (Fig. 21a, c): ground colour black; mid-dorsal depression on ST1+2 extending only halfway across tergite; median marginal setae absent on ST1+2 and weak on T3; T4-T5 with a complete row of marginal setae; discal setae absent on all tergites; sex patch covering ventral surfaces of T4-T5; dorsal surface of abdomen covered in brassy-silver tomentum on ST1+2-T4; T5 with brilliant gold tomentum over its entirety. Terminalia: sternite 5 (Fig. 21f) with a deeply excavated median cleft, rounded U-shaped, inner margins covered in dense tomentum. Lateral lobes of sternite rounded apically, with 2-3 strong setae surrounded by 2-3 shorter, weaker setulae. Anterior plate of sternite 5 from subequal to slightly longer than apical lobes, unsclerotised "window" rectangular, 1/2 as wide as median cleft and slightly convex. Cerci in posterior view (Fig. 21d) slightly rectangular, shorter than surstyli, blunt and rounded at apex, fused along basal 2/3, separating medially along apical 1/3; in lateral view with a strong downward curve in apical 1/3; densely setulose along basal 2/3 dorsally, setulose ventrally along entire length (visible in lateral view). Surstylus in lateral view (Fig. 21e) almost parallel-sided along its length, rounded at tip; surstylus appearing to be fused with epandrium; when viewed dorsally, surstyli appearing slender and straight, not strongly convergent. Pregonite broad and well-developed, bent medially, apically rounded, devoid of setulae. Postgonite elongate, slender, very slightly hooked at tip, subequal in length to pregonite. Distiphallus vaguely cone-shaped, could be seen as rectangular, weakly flaring apically, with a slender median longitudinal sclerotised reinforcement on its posterior surface and a broad, anterolateral, sclerotised acrophallus on each side, joining the plate of opposite side on anterior surface near apex.

Female. Length: 5-7 mm. As male, differing only by the presence of two pairs of proclinate orbital setae.

Diagnosis

Hyphantrophaga myersi (Aldrich) can be distinguished from all other Hyphantrophaga species by the following combination of traits: facial ridge with stout setae along entire length and sternite 5 distinctly golden tomentose.

Distribution

Neotropical species recorded from South America: Guyana, Venezuela; Lesser Antilles: Trinidad & Tobago; and Mesoamerica: Costa Rica, ACG (Provinces of Alajuela and Guanacaste), 180-640 m elevation.

Ecology

Hyphantrophaga myersi has been reared 43 times within the ACG inventory from eight species of Lepidoptera , six in the family Erebidae ( Renodes curviluna (Druce, 1890), Anomis illita Guenée, 1852, Anomis luridula Guenée, 1852, Eulepidotis folium (Schaus, 1911), Helia sueroides ( Guenée, 1852) and Dysschema lycaste (Klug, 1836)); and two in the family Geometridae ( Semiothisa sp. and geoJanzen01 Janzen17), in rain forest, dry forest and dry-rain lowland intergrade.
