Triozoida Crawford 

( Figs 36View FIGURES 28 – 36, 58View FIGURES 47 – 58, 70View FIGURES 59 – 70, 83View FIGURES 81 – 83)

Diagnosis: Head about as wide as mesoscutum, widely separated from prothorax ( Fig. 70View FIGURES 59 – 70); hind margin strongly concave; lateral ocelli raised on tubercles; genal processes short, broad, subtruncate, peg-like, with long pubescence; separated with a U-shaped gap ( Fig. 36View FIGURES 28 – 36), with a small dorsoapical tubercular swelling. Clypeus prominent with two apical setae. Antennae 1.5–2.5 times longer than head width; terminal setae subequal and pointed. Forewing acutely pointed apically ( Fig. 58View FIGURES 47 – 58), with point outside m1; vein M+Cu1 present, greatly reduced; often with a dark stripe along veins R+M+Cu1 and base of R. Meracanthus large and pointed; metatibia with genual spine and with 2–4+(3–4) apical spurs.

Biology and damage: Immatures of Triozoida limbata (Enderlein)  , covered in wax and producing honeydew, develop inside roll leaf galls on Psidium guajava  ( Myrtaceae  ). Further damage turn leaves yellow or reddish and subsequently become necrotic ( Gallo et al. 2002).

Host-plants: Myrtaceae ( Hodkinson 1989)  .

Distribution: Central and South America ( Hodkinson 1989).
