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.
