Diagnosis.

Large, light coloured species, with fore wing membrane unpatterned, antennae and genal processes long, and paramere short.

Description.

Adult. General body colour yellow-green to yellow-brown, last 7-8 antennal segments darker brown. Fore wing membrane uniformly pale fuscous (Fig. 1D). Fore wing apex acute; pseudopterostigma medium long (Fig. 6I), 0-1 cross pseudoveins in basal portion of cell r1; surface spinules sparsely distributed, apparently absent from c+sc; medium long setae on ventral margin and medium short setae on veins and dorsal margin. Antennae long (AL > 1 mm, ratio AL:HW 1.61) (Fig. 6A); genal processes long (GP > 0.50 mm, ratio HW:GP < 1.40) and slightly upturned at apices (Fig. 6A); short to minute setae on vertex and thorax. Meracanthus small (Fig. 6D), genual spine reduced (Fig. 6C). Male terminalia (Fig. 6H): paramere short (ratio PL:HW 0.24), tapering to small, anteriorly projecting apex with two short stout setae; distal aedeagus segment long relative to paramere (ratio PL:AEL 1.14), apex developed into a large rounded hook with bluntly acute apex.

Egg. Unknown.

Immature. Unknown.

Host plant.

Planchonella sandwicensis  .

Distribution.

Kauai. Only known from one location in Kokee State Park.

Etymology.

Named for the large body size (adjective in the nominative singular).

Comments.

This is the largest Swezeyana  species and is only known from a single male; fore wing type suggests it is part of the elongagena  species group, but the paramere shape is somewhat similar to other reticulata  group species on Kauai. As no molecular sequences are available for this species, the group affiliation remains uncertain, but this species and the other Kauai species may represent early divergence of the elongagena  and reticulata  species groups.
