Paurocephala wilderi Crawford  

( Žgures 13F, 14F, 15F, L, 16F) Paurocephala wilderi Crawford, 1927: 29   . Lectotype ( BMNH), examined, by present designation.  

Description. Species of the wilderi   type.

Adult: head brown; vertex covered by short setae. 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 Žfth marginally curved anteriorly, few short setae posteriorly visible from lateral view; inner surface with two hooks apically, group of setae conŽned anteriorly in basal third. Measurements and ratios as in table 2A–C.

Fifth instar larva: unknown.

Host plants. Adults were collected on Ficus sp.   ( Moraceae   ) which may be the host.

Distribution. American Samoa ( Crawford, 1927).

Material examined. American Samoa: 1, lectotype and 2, 3   , paralectotypes, Tutuila, Pago Pago, 22 September 1922, Ficus sp.   (O. H. Swezey and G. P. Wilder); 1, 1, same data but 4 August 1940 (O. H. Swezey) ( BMNH, MHNG, NHMB, USNM). Dry and slide mounted   .

Comments. P. wilderi Crawford   is distinguished from the other species of the wilderi   type by the reduced number of spurs along metatibia and the long pterostigma. To avoid future taxonomic confusion a lectotype is designated here for P. wilderi Crawford.
