Etymology: Named for narrow rc cell of the forewing in dorsal view after “artus” Latin for narrow.

Diagnosis: Recognized by the mid-sized body length (1.29 mm), elongate oval forewing outline, rc about 5 times as long as wide (black star), tc about 3 times as long as wide ( Fig. 2 View FIGURE 2 ), lateral lobe on right side of pygophore (black star), slender vesica, and short, broad anophoric process with blunt tip (black arrow) ( Fig. 7 View FIGURE 7 ). Similar to G. auriculus , sp. n. that is also known from Veracruz in Mexico but distinguished by the characters listed in the diagnosis.

Description: Male: Total body length 1.29 mm, length from posterior margin of pronotum to posterior wing margin 1.04 mm; greatest width across pronotum 0.54 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 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, in distinct clusters; scutellum in dorsal view abruptly narrowed to tip, tip rounded. Forewing: with outline broad anteriorly, elongate oval; membrane contributing about one third of forewing length, posterior distal margin squarish, veintracing areoles on proximal part of wing absent; C+Sc 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 5 times as long as wide; tc 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 almost triangular; cub almost reaching wing margin; dc1 horse headshaped. Legs: Claws long. Genitalia ( Fig. 7 View FIGURE 7 ): Pygophore with lobe on right side; vesica with between half and one loop, not reaching right pygophore margin, relatively slender at midpoint, tapering to acute tip, close to apex rounded; anophoric ridge with process, process short, broad, with single lobe curved, tip blunt; right paramere curved, tapering, basal process narrow; left paramere, tapering, basal process narrow.

Female: As in male and generic description.

Collecting method and habitat: Collected using sifting leaf litter, Winkler extraction in mixed hardwood forest.
