Etymology: Named for the small body size after “minutus” Latin for small.

Diagnosis: Recognized by the small size (1.14 mm), inflated tip of scutellum (white arrow), well-defined proximal part of Cu (black arrow), and dark coloration (female-based) ( Fig. 3 View FIGURE 3 ).

Description: Female: Total body length 1.14 mm; length from posterior margin of pronotum to posterior wing margin 0.90 mm; greatest width across pronotum 0.52 mm; greatest width across forewings 0.71 mm. General coloration: mix of pale and darker brown or reddish brown. Vestiture: Dorsum with dense 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 inflated. Forewing: With outline elongate oval; membrane contributing about one third of forewing length, posterior distal margin rounded, vein-tracing areoles on proximal part of wing absent; C+Sc uniformly fairly broad; distal process of R pronounced; An1 wing organ on corium absent (as in all females); 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 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 with basal portion fairly narrow and elongate. Legs: Claws long. Genitalia: As in generic description.

Male: Unknown.

Collecting method and habitat: Unknown.
