Etymology: Named for the stout vesica after “castigatus” Latin for stout.

Diagnosis: Recognized by the mid-sized body length (1.48 mm), elongate oval forewing outline, wide C+Sc (black arrow), small vein-tracing areoles along scc, rc, rc1 (white arrow) ( Fig. 2 View FIGURE 2 ), slightly extended right pygophore margin (black star), vesica relatively short and thick, tapering into acute tip, and without anophoric process ( Fig. 7 View FIGURE 7 ). Similar to G. auriculus , sp. n. in length and shape of vesica but differentiated by differentiated from that species by the slender and long rc1.

Description: Male: Total body length 1.48 mm; length from posterior margin of pronotum to posterior wing margin 1.27 mm; greatest width across pronotum 0.66 mm; greatest width across forewings 0.88 mm. General coloration: mix of pale and darker brown or reddish brown. Vestiture: Dorsum with dense setae, setae long; setae on posterior margin of forewing long. Structure: Head: Eye almost half as high as head; muscle scars large.

Thorax: Anterior pronotal margin concave, posterior margin slightly concave; pits on pronotum medium-sized, 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 squarish, vein-tracing areoles on proximal part of wing present; areoles small, distributed along scc, rc, rc1, and tc; C+Sc broad, wider at widest part of wing; distal process of R pronounced; An1 wing organ on corium strongly inflated, elongate, with median notch, without notch articulating with claval process; scc about 2 times as wide as long; 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 of similar width as 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 relatively wide and short. Legs: Claws long. Genitalia ( Fig. 7 View FIGURE 7 ): Pygophore with slightly extended right margin; vesica with about half loop, not reaching right pygophore margin, thick at midpoint, tapering to acute tip, close to apex rounded; anophoric ridge without process; right paramere curved, tapering, basal process narrow; left paramere straight, tapering, basal process narrow.

Female: Unknown.

Collecting method and habitat: Collected using flight intercept trap in rainforest.
