Triozoida Crawford
(Figs 36, 58, 70, 83)
Diagnosis: Head about as wide as mesoscutum, widely separated from prothorax (Fig. 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. 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. 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).
