Description

Male (Fig. 9). Length: 14 mm. Head (Fig. 9b): antenna: medial surface of first flagellomere with a dark orange tinge along upper margin, closest to pedicel; pedicel black to dark brown; arista 1.5X as long as first flagellomere, dark brown and minutely pubescent; palpus dark yellow and haired; fronto-orbital plate, parafacial and gena silver pollinose; gena with few fine hairs along lower margin; frontogenal suture darkened but not black. Thorax (Fig. 9a, c): entirely gray pollinose; dorsum of thorax and scutellum with conspicuous black hairs covering surface; sternopleura, hypopleura, pteropleura and ventral surface of abdomen yellow-white pilose; 3 katepisternal bristles; 3 postsutural supra-alar bristles, 2nd postsutural supra-alar 3X as long as first; postpronotum and anepisternum bearing fine black hairs; scutellum bearing 1 pair of almost indistinct discal bristles, and 3 strong lateral marginal bristles; underside of scutellum bearing a tuft of black hairs near basal marginal bristle. Legs: black in ground color, femora covered in long yellow hairs interspersed around femoral bristles; tibiae of dark yellow ground color; tarsi all black. Wing: smoky clear translucent; wing veins slightly infuscate. Abdomen (Fig. 9a): 1 pair of median marginal bristles on ST1+2; row of marginal bristles on T3 and T4; median discal bristles on T3 and T4; black ground color, with silver pollen on either side of mid-dorsal depression on ST1+2; silver pollen on anterior half of T3 and T4; T5 with 2 silver pollinose spots on either side; silver pollinosity extending to underside of abdomen on T3 and T4. Terminalia (Fig. 9d, e, f): sternite 5 with two small lobes, inner margin covered in dense pollinosity appearing slightly darker than surrounding cuticle; apical edges of lobes of sternite 5 bearing many long, stout, outwardly pointed bristles interspersed among shorter hairs, with longer bristles closest to lobe margin; sternite 5 with wide Y-shaped median cleft, 0.48X length of sternite from lobe apex to base; cercus sharply pointed, distinctly tapered; apical section 1.6X length of upper lobe; strongly curved downwards when viewed laterally, lacking any upward hook at its tip; surstylus narrow, curved downwards, and scythe-like in lateral view; surstylus haired along almost its entire length, with tip not lobed when viewed dorsally; in dorsal view, surstyli angled medially so that tips are almost pointing inwards; surstylus 1.3X as long as cercus.

Female: Unknown.

Diagnosis

Uramya infracta can be distinguished from all other Neotropical species of Uramya by the following combination of traits: dark brown to black antennae with only a slight orange tinge and dark brown pedicel, thorax with black hairs interspersed among the bristles dorsally, and yellow-white hairs on sides and ventrally, underside of scutellum with a tuft of black hairs near basal marginal bristle, 1 pair of median marginal bristles on ST1+2, and a row of marginal bristles on T3 and T4.

Etymology

The species epithet is derived from the latin adjective " infractus " meaning broken or weakened, in reference to the broken band of silver pollinosity on T5, which appears as two pollinose spots.

Distribution

Costa Rica, ACG (Prov. Guanacaste), 900 m.

Ecology

Uramya infracta has been reared only once, from a total of 153 wild-caught non-sibling Natada fusca Druce ( Limacodidae ) caterpillars in ACG rain forest.
