Etymology: Named after our dear mentor, colleague, and friend, the grande dame of South American heteropteran systematics, Jocelia Grazia.
Diagnosis: Recognized by the small body length (1.16 mm), very broad C+Sc margin (white arrow) (Fig. 3), slightly s-shaped vesica, and short, curved anophoric process (black arrow) (Fig. 7).
Description: Male: Total body length 1.16 mm; length from posterior margin of pronotum to posterior wing margin 0.89 mm; greatest width across pronotum 0.56 mm; greatest width across forewings 0.69 mm. General coloration: mix of pale and darker brown or reddish brown. 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 pointed. Forewing: With outline broad anteriorly; membrane contributing about one third of forewing length, posterior distal margin squarish, veintracing areoles on proximal part of wing absent; C+Sc very broad, wider at widest part of wing; distal process of R pronounced; An1 wing organ on corium strongly 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 of similar width as other veins; distal margin of rc1, rc, and tc cells s-shaped; rc2–3 trapezoidal; cub almost reaching wing margin; dc1 with basal portion relatively wide and short. Legs: Claws long. Genitalia (Fig. 7): Pygophore without lobe on right side; vesica with between half and one loop, not reaching right pygophore margin, thick at midpoint, tapering to acute tip, close to apex slightly s-shaped; anophoric ridge with process, process short, with single lobe curved, tip pointed; right paramere curved, tapering, basal process narrow; left paramere straight, tapering, basal process narrow.
Female: As in male and generic description.
Collecting method and habitat: Collected using Winkler extraction in second growth forest and tropical wet forest.
