Etymology: Named for the three lobes on the anophoric process after “trilobus” Latin for three lobes.

Diagnosis: Recognized by the mid-sized body length (1.40 mm), broad C+Sc (black arrow) ( Fig. 4 View FIGURE 4 ), vesica with almost one circular loop with acute tip, and anophoric process with multiple pointed tips (black arrows) ( Fig. 7 View FIGURE 7 ).

Description: Male: total body length 1.40 mm; length from posterior margin of pronotum to posterior wing margin 1.03 mm; greatest width across pronotum 0.61 mm; greatest width across forewings 0.85 mm. General coloration: mix of pale and darker brown or reddish brown. Vestiture: Dorsum with sparse 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 pointed. Forewing: With outline broad anteriorly; membrane contributing about one third of forewing length, posterior distal margin squarish, 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 inflated, elongate, 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 about 3 times as long as wide; part of An1 and Cu forming posterodistal margin of tc slightly wider than 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 fairly narrow and elongate. Legs: Claws long. Genitalia ( Fig. 7 View FIGURE 7 ): Pygophore without lobe on right side; vesica with almost one loop, not reaching right pygophore margin, relatively slender at midpoint, tapering to acute tip, close to apex rounded; anophoric ridge with process, process long, with multiple pointed tips; right paramere curved, broad throughout, basal process broad; left paramere curved and tapering, basal process broad.

Female: As in male and generic description.

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