Diagnosis.

Previously, this species was known from the single (slightly teneral) female holotype ( Sosa 2015). Subsequently, additional female specimens became available for comparison; unfortunately, the male remains unknown. This species resembles both U. favrei and U. diazi in that adults have a golden head, black stripe on the gena and basolateral section of the clypeus, a pair of broad, curved, brown marks on the vertex, and broad dark brown or reddish brown lateral stripes on the prothorax. However, a pale flagellum distinguishes U. yutajensis from U. diazi , and the dark crossveins and the four dark marks in the pterostigma differentiate it from U. favrei .

Redescription.

Head yellow dorsally; vertex smooth, shiny; inverted U-shaped marking prominent, dark red, broad posteriorly, separated or lightly connected anteromesally, not extending anteriorly to area between scapes; dorsal antennal fossa pale, with dark reddish stripe mesally, reaching mesal base of scape; area between eyes and posterior half of vertex cream-colored, unmarked; frons, clypeus yellow, without markings; gena with large, black mark from eyes onto clypeus; tentorial pits amber. Antenna with scape cream-colored, with broad, diffuse dark red stripe extending full length, onto dorsal surface of pedicel; pedicel with frontal surface pale, dorsal surface dark red; flagellum yellow, except basal flagellomere brownish; maxillary palp with basal two segments pale, distal three segments black; labial palp with basal segment pale, distal two segments black.

Prothorax green, with pair of broad, dark red stripes along entire lateral length, with pair of pale, circular spots at level of transverse furrow; transverse furrow in posterior region of prothorax extending laterally only to pale spots. Mesothorax, metathorax green, with ivory mesally; mesonotum with pair of reddish spots on anterior margin of scutellum; metanotum unmarked. Legs pale, unmarked. Measurements: head width: 1.4-1.6 mm; ratio head width: eye width: 2.3: 1; prothorax width: 1.1-1.4 mm, length: 0.7-0.8 mm.

Forewing, hindwing elongate; forewing with round apex; hindwing with slightly acute apex. Forewing with venation not inflated, except at base of Cu; stigma slightly opaque, with four to five crossveins below, basal three to four crossveins dark brown, surrounding area marked with dark brown; basal subcostal crossvein, costal, cubital crossveins black; longitudinal veins mostly green; base of Rs dark brown; transverse veins, crossveins mostly brown or reddish brown, without suffusion on surrounding membrane; gradate veins dark brown to black, with some suffusion on surrounding membrane. Forewing 15.8-15.9 mm long, 5.0-5.2 mm wide (ratio, L: W = 3.0-3.1: 1); height of tallest costal cell 1.0-1.1 mm (cell number 5-6); length of first intramed ian cell 1.0 mm; 11-12 radial cells (closed cells between R and Rs); third gradate cell 1.3-1.6 mm long, 0.5 mm wide (ratio, L: W = 2.6-3.1: 1); fourth gradate cell 1.3 mm long, 0.5 mm wide (ratio, L: W = 2.7: 1); 4 Banksian cells (b cells), 4 b’ cells; 5-7 inner gradates, 7-8 outer gradates. Hindwing with venation green; 14.2-14.5 mm long, 4.3-4.5 mm wide (ratio, L: W = 3.0-3.2: 1), 11 radial cells, 3 Banksian (b) cells, 4 b’ cells, 4-6 inner gradates, 6-7 outer gradates.
