Etymology: Named for sickle shaped vesica after “flax” Latin for sickle.

Diagnosis: Recognized by the mid-sized body length (1.56 mm), dense vestiture, part of An1 and Cu forming posterodistal margin of tc more pronounced than other veins (black arrow) ( Fig. 2 View FIGURE 2 ), long, relatively slender vesica, with s-shaped bent proximal of acute tip, and short, curved anophoric process with pointed tip (black arrow) ( Fig. 7 View FIGURE 7 ). Most similar to G. bierigi   , sp. n., that is also known from Costa Rica, but distinguished by the much smaller distance of cub from the wing margin compared to G. bierigi   , sp. n.

Description: Male: Total body length 1.56 mm; length from posterior margin of pronotum to posterior wing margin 1.27 mm; greatest width across pronotum 0.65 mm; greatest width across forewings 0.87 mm. General coloration: mix of pale and darker brown or reddish brown. Vestiture: Dorsum with dense, long setae; setae on posterior margin of forewing long. Structure: Head: Eye about one third as high as head; muscle scars not observed. Thorax: Anterior pronotal margin concave, posterior margin slightly concave; pits on pronotum large, evenly distributed; scutellum in dorsal view abruptly narrowed to tip, tip pointed. Forewing: With outline broad anteriorly, elongate oval; membrane contributing about one third of forewing length, posterior distal margin squarish, vein-tracing areoles on proximal part of wing absent; C+Sc uniformly broad; 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 5 times as long as wide; tc more than 3 times as long as wide; part of An1 and Cu forming posterodistal margin of tc more pronounced than other veins; distal margin of rc1, rc, and tc cells double s-shaped; rc2-3 almost triangular; cub almost reaching wing margin; dc1 with basal portion relatively wide and short. 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, relatively slender at midpoint, tapering to acute tip, close to apex slightly s-shaped; 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: As in male and generic description.

Collecting method and habitat: Collected using Malaise trap in unknown habitat.
