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
), lateral lobe on right side of pygophore (black star), slender vesica, and short, broad anophoric process with blunt tip (black arrow) (
Fig. 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
): 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.
