Paurocephala pterospermi sp. n.

(gures 32B, D, J, 33F, L, 34F, 46)

Description. Species of the brevicephala type.

Adult: head yellow, sides along coronal suture and genae white; vertex covered by inconspicuous setae. Clypeus light brown. Antenna yellow, segment 8 orange to brown; segment 7 with a long basal seta. Thorax yellow to orange with white markings along body axis and covered by inconspicuous setae dorsally, yellow laterally and ventrally. Metascutellar horn small, wide basally, blunt apically. Forewing transparent to light yellow; veins yellow, apically brown to forewing margin, central part of vein A brown; pterostigma white, brown apically. Forewing with short setae on veins (vein Rs with 19–21 setae); Rs vein marginally curved throughout. Surface spinules present in all cells of forewing, reduced in c1 sc; radular spinules lacking. Legs including tarsal segments, white, femur yellow. Meracanthus short, almost straight laterally, rounded apically. Abdominal tergites yellow to orange, sternites brown, genitalia yellow. Male paramere elongate, widest basally, tapering apically and directed posteriorly in apical half, few long setae posteriorly visible from lateral view; inner surface with a hook apically. Measurements and ratios as in table 2A–C.

Fifth instar larva: colour unknown. Similar to P. brevicephala but with anus in terminal position. Measurements and ratios as in table 3.

Host plants. Pterospermum sp. (Sterculiaceae) .

Distribution. Philippines (Palawan) and Malaysia (Sabah).

Material examined. HOLOTYPE, Philippines: Palawan, Inagauan River , 700 m, 1 February 1988, Pterospermum sp. (J. H. Martin) ( BMNH). Dry mounted.

PARATYPES. Philippines: 8, 11, 43 larvae, same data as holotype but 30 January to 1 February 1988 . Malaysia: 2, 7, Sabah, Poring Hot Springs, 500 m, 7 May 1987 (D. Burckhardt and I. Löbl); 1, same data but Mt Kinabalu , 600 m, 2 May 1987, Leptospermum sp. ( MHNG, NHMB). Dry and slide mounted .

Comments. P. pterospermi sp. n. is similar to P. ambigua sp. n. from which it is distinguished by the paramere shape and long setae on forewing veins. The material collected in Sabah diVers in having shorter setae on forewing veins and reduced areas of surface spinules in forewing cells, which is considered here as variation.
