Etymology: Named for the hook-shaped vesica after “uncus” Latin for hook (noun in apposition).

Diagnosis: Recognized by the small mid-sized body length (0.67 mm), elongate oval body shape (length to width ratio 3.4) ( Fig. 4 View FIGURE 4 ), and apex of vesica hook-shaped ( Fig. 7 View FIGURE 7 ).

Description: Male: Total body length 1.19 mm; length from posterior margin of pronotum to posterior wing margin 0.97 mm; greatest width across pronotum 0.27 mm; greatest width across forewings 0.35 mm. General coloration: uniformly pale. Vestiture: Dorsum with sparse setae, setae short; setae on posterior margin of forewing long. Structure: Head: Eye almost half as high as head; muscle scars indistinct. Thorax: Anterior pronotal margin concave, posterior margin slightly concave; pits on pronotum small, evenly distributed; scutellum in dorsal view gradually narrowed to tip, tip pointed. Forewing: With outline elongate oval; membrane contributing about one third of forewing length, posterior distal margin rounded, vein-tracing areoles on proximal part of wing absent; C+Sc broad, wider at widest part of wing; distal process of R pronounced; An1 wing organ on corium inflated, elongate, with median notch, without notch articulating with claval process; rc1 about 3 times as long as wide, slightly wider anteriorly; rc about 4 times as long as wide; tc about 3 times as long as wide; part of An1 and Cu forming posterodistal margin of tc slightly wider than other veins; distal margin of rc1, rc, and tc cells double s-shaped; rc2–3 trapezoidal; cub almost reaching wing margin; dc1 with basal portion fairly narrow and elongate. Legs: Claws long. Genitalia ( Fig. 7 View FIGURE 7 ): Pygophore without lobe on right side; vesica with between half and one loop, surpassing right pygophore margin, thick at midpoint, with bottle opener-shaped apex, close to apex rounded; anophoric ridge with process, process short, with single lobe curved, tip pointed; right paramere curved, broad throughout, basal process broad; left paramere straight, tapering, basal process broad.

Female: Unknown.

Collecting method and habitat: Collected using flight intercept trap.
