Paratypes: PERU: Amazonas: Pacaya–Samiria National Reserve, 5.2012°S 74.59319°W, 280m, 07 Nov 1980, CI. Vaucher , 4♂ ( UCR _ ENT 00089589 , UCR_ENT 00089591-UCR_ENT 00089593), 5♀ ( UCR _ ENT 00089594 - UCR_ENT 00089598) ( MHNG) . Unknown locality in Peru , no date provided, collector unknown, 1♀ ( UCR _ ENT 00089582 ) ( MHNG) .

Etymology: Named for the multiple lobes on the anophoric process after “pluri” and “lobus” Latin for multiple lobes.

Diagnosis: Recognized by the small body length (1.14 mm), relatively short rc1, rc, and tc cells (black star) ( Fig. 3 ), slender vesica with one loop, and multilobed anophoric process, with combination of blunt and acute tips (black arrow) ( Fig. 7 ).

Description: Male: Total body length 1.14 mm; length from posterior margin of pronotum to posterior wing margin 0.8 mm; greatest width across pronotum 0.44 mm; greatest width across forewings 0.67 mm. General coloration: uniformly pale. Vestiture: Dorsum with sparse setae, setae short; 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 medium-sized, 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 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 weakly inflated, elongate, with median notch; without notch articulating with claval process; rc1 about 3 times as long as wide, slightly 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 ): Pygophore without lobe on right side; vesica with one loop, not reaching right pygophore margin, relatively slender at midpoint, tapering to blunt tip, close to apex rounded; anophoric ridge with process, process long, with multiple lobes, tip blunt; right paramere curved, broad throughout, basal process broad; left paramere straight, tapering, basal process narrow.

Female: As in male and generic description.

Collecting method: Collected using Winkler extraction.
