Clypeus yellow. Antenna brown, segments 1–3 and basal half of segment 4 yellow; segment 9 without a long basal seta. Thorax entirely dark brown and covered by inconspicuous setae dorsally. Metascutellar horn small, blunt apically. Forewing transparent with a brown pattern apically, throughout cell m1 and in adjacent areas of r2 and m2; veins yellow to light brown; pterostigma yellow. Forewing with inconspicuous setae on veins (vein Rs with 13–16 setae); Rs vein marginally curved throughout entire length. Surface spinules present in all cells of forewing except in cell c1 sc; radular spinules present in m2, reduced in cu1. Legs yellow to brown, tarsal segments darker. Meracanthus long, straight laterally, rounded apically. Abdomen including genitalia, brown. Male paramere long, widest basally and tapering apically, apical fth marginally curved anteriorly, few short setae posteriorly visible from lateral view; inner surface with two hooks apically, group of setae con ned anteriorly in basal third. Measurements and ratios as in table 2A–C. Fifth instar larva: unknown.  Host plants. Adults were collected on  Ficussp. (Moraceae)which may be the host.  Distribution. American Samoa( Crawford, 1927).  Material examined.   American Samoa: 1, lectotypeand 2, 3,  paralectotypes, Tutuila, Pago Pago,  22 September 1922,  Ficussp.( O.

To avoid future taxonomic confusion a lectotypeis designated here for  P. wilderiCrawford.  Unidenti ed materialThe following material could not be identi ed due to insuYcient material.
