Trioza lehua Crawford, 1925: 29

Adult colour.

General body colour yellow or orange. Fore wing membrane clear.

Adult structure.

Fore wing apex rounded; surface spinules distributed in all cells; short setae on margins and veins (Fig. 27A). Antennae short (length av. 0.81; ratio AL:HW av. 1.62); genal processes short (ratio VL:GP av. 2.30) and rounded apically; medium short setae on vertex and short setae on thorax; distal proboscis segment short (av. length 0.08); hind tibia slender, length subequal to head width (ratio HW:HT av. 1.02) (Fig. 27 B–C, F–G). Male terminalia (Fig. 27 D–E): paramere slightly shorter than proctiger (ratio MP:PL av. 1.08), broad and parallel-sided before tapering to a somewhat flat-topped apex with anteriorly directed hook; distal aedeagus segment length subequal to paramere (ratio PL:AEL av. 1.04) with base slightly angular and inflated, and a large hooked apex (ratio AEL:AELH av. 2.30). Female terminalia (Fig. 27 H–I): proctiger dorsal surface more or less straight, apex bluntly acute, anal ring long (ratio FP:RL av. 3.50); subgenital plate with slight medial bulge ventrally, and acute apex; ovipositor apex with reduced serrations (2 above, 2 below), valvulae dorsalis not strongly convex dorsally.

Egg .

Unpigmented, not sinusoidal, smooth, no microsculpturing, short pedicel 1/4 length from base, tail lacking.

Immature.

Unknown (see comment under Pariaconus crassiorcalix).

Host plant notes.

Kauai

Distribution notes.

The type location is recorded only as “Nualolo” .

Biology.

The biology of this species is unknown, it may form cup galls on stems as morphologically it is close to the two stem cup-gallers, Pariaconus caulicalix and Pariaconus crassiorcalix .

Type material.

Holotype, male (?) (dry mounted, damaged, abdomen and fore wings missing, BPBM). See Table 2 for details of type and other material examined for this study.
