(Figs 2, 7, 9)
Holotype. Male. GUATEMALA: San Marcos: Bojonal Road, 14.94786°N 91.8837°W, 1618 m, 04 Jun 2015, R. Anderson, 1♂ (UCR _ ENT 00127123) (UCR).
Etymology: Named for the duck head-shaped basal process of the right paramere after “anas” meaning duck in Latin.
Diagnosis: Recognized by the mid-sized body length (1.45 mm), oval forewing outline, narrow C+SC (black arrow), rc1 about 3 times as long as wide and slightly wider anteriorly (white arrow), tc more than 3 times as long as wide (Fig. 2), the short, slender, and straight vesica with blunt, expanded tip, and the broad, duck head-shaped basal process of the right paramere (Fig. 7).
Description: Male: Total body length 1.45 mm; length from posterior margin of pronotum to posterior wing margin 1.23 mm; greatest width across pronotum 0.63 mm; greatest width across forewings 0.81 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 mediumsized, evenly distributed; scutellum in dorsal view abruptly narrowed to tip, tip pointed. Forewing: With outline oval; membrane contributing about one third of forewing length, posterior distal margin rounded, vein-tracing areoles on proximal part of wing absent; Sc+C uniform, relatively narrow; 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, slightly wider anteriorly; rc about 5 times as long as wide; tc more than 3 times as long as wide; distal margin of rc1, rc, and tc cells double s-shaped; rc2-3 almost triangular; cub almost reaching wing margin; dc1 with basal portion fairly narrow and elongate. Legs: Claws long. Genitalia (Fig. 7): Pygophore without lobe on right side; vesica with between half and one loop, surpassing right pygophore margin, thick at midpoint, tapering to blunt, expanded tip, close to apex slightly s-shaped; anophoric ridge with process, process short, with single lobe curved, tip blunt; right paramere curved, tapering, basal process duck head-shaped; left paramere straight, tapering, basal process broad.
Female: Unknown.
Collecting method and habitat: Collected in cloud forest litter using sifting leaf litter.
