(Figures 1–3)
Holotype Male: VENEZUELA. Mérida state. Mérida city, La Hechicera, [8.627491o N / 71.162393], 1900 m, 19.i.1988, F. Díaz Leg. Deposited in the MIZA.
Diagnosis. This species is the only known Ungla species that has the following set of features: a yellow head with raised vertex bearing diffuse red marks laterally, scape with red mark dorsoapically, pronotum with broad dark red lateral stripes, and mesoscutum marked with red laterally. Males have enlarged spiracles, and the dorsal margins of the sternites are clearly concave in both sexes.
Description. Head. Yellow, vertex smooth, with paired, longitudinal marks diffuse, red; gena black, basolateral margin of clypeus black. Maxillary, labial palpi black, apices yellow. Antenna (Fig. 1): scape yellow, dorsoapically red marked; pedicellus yellow; flagellum yellow, with pale bristles (Fig. 1 B–C, E–G). Thorax. Green; pronotum with broad, dark red stripe laterally; mesoscutum red marked laterally; pleural, sternal areas, legs pale green (Fig. 1 E). Wings (Fig. 1 H): forewing with longitudinal veins pale green; crossveins red, except basal subcostal crossvein black; gradate series converging distally; basal inner gradate meeting Psm; hindwing with longitudinal veins and crossveins green pale.
Abdomen. Male terminalia (Fig. 2): A1–8 with enlarged, ovate spiracles. T9+ect cone-shaped, with acute basilateral corner; callus cerci ovate with ca. 30 trichobotria. S8+9 ventral margin 1.9 times longer than height of anterior margin; dorsal margin tapering toward apex; apex densely covered by long setae; circumference of A8 spiracle as long as circumference of callus cerci (Fig. 2 A). Gonarcal arch with “U” shape; lateral apodeme broad, rounded distally, with straight digitiform horn; arcessus square basally, tapering abruptly at apex (Fig. 2 C–D).
Female terminalia (Fig. 3): A1–8 with spiracles ovate; T9+ect rectangular, with basoapical margin rounded; callus cerci round, with ca. 32 trichobothria. Gonapophysis lateralis ovate with dense, long setae. S7 rectangular, with dorsal margin lightly sinuous; ratio of ventral margin length: anterior margin height ~ 1.4: 1. Spermatheca pillbox-shaped, ventral impression deep, spermathecal duct ca 1.4 times longer than height of spermatheca and velum (Fig. 3 C–D). Subgenitale rounded, with dorsal lobes rounded apically, widening basally (Fig. 3 E).
Measurements (n=3). Head: width = 1.3–1.4 mm; Pronotum: length = 0.8 mm, width = 0.8–1.0 mm. Forewings: length = 13.3 mm, width = 4.3 mm, length:width ratio = 3.1: 1; intramedian cell length = 0.8 mm; maximum height of costal area = 0.8 mm; four to six inner, five to eight outer gradates. Hindwing: length = 11.3 mm, width = 3.5 mm, length/width ratio = 3.2: 1; three to four inner, five to six outer gradates.
