Etymology: Named for the large lobe on the right side of the pygophore after “auricula” Latin for lobe.

Diagnosis: Recognized by the mid-sized body length (1.23 mm), rc about 4 times as long as wide (white star), tc less than 3 times as long as wide ( Fig. 2 View FIGURE 2 ), large lateral lobe on right side of pygophore (black star), slender vesica tapering into acute tip, and anophoric process very short, curved, and pointed (black arrow) ( Fig. 7 View FIGURE 7 ). Similar to G. artus , sp. n. that is also known from Veracruz in Mexico but distinguished by the characters listed in the diagnosis. Additionally, G. auriculus , sp. n. and G. castigatus , sp. n. have a similar vesica, but differ in rc1 shape.

Description: Male: Total body length 1.23 mm; length from posterior margin of pronotum to posterior wing margin 0.9 mm; greatest width across pronotum 0.55 mm; greatest width across forewings 0.75 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 extremely 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 large, evenly distributed; scutellum in dorsal view abruptly narrowed to tip, tip rounded. Forewing: With outline broad anteriorly; 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 strongly inflated, rounded, with median notch, without notch articulating with claval process; rc1 about 3 times as long as wide, much wider anteriorly; rc about 4 times as long as wide; tc 3 less than 3 times 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 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 with large lobe on right side; vesica with between half and one loop, not reaching right pygophore margin, thick at midpoint, tapering to acute tip, close to apex rounded; anophoric ridge with process, process short, with single lobe curved, tip pointed; right paramere curved, tapering, basal process narrow; left paramere straight, tapering, basal process narrow.

Female: As in male and generic description.

Collecting method and habitat: Collected using sifting leaf litter, Winkler extraction in broadleaf forest and tree ferns.
