Paurocephala palawanensis sp. n.

(gures 21D, 23D, 24G, 25D, 26D, 28D)

Description. Species of the psylloptera type.

Adult: head brown, vertex yellow, genae white; vertex covered by long setae. Clypeus brown. Antenna yellow, apical third of segment 4, entire segment 6, apical two-thirds of segment 8, and entire segments 9 and 10 brown; segment 9 without a long basal seta. Thorax brown and covered by short setae dorsally, yellow to light brown laterally and ventrally. Metascutellar horn small, pointed apically. Forewing transparent to white; veins yellow, apically light brown to forewing margin; pterostigma white. Forewing with short setae on veins (vein Rs with 24–33 setae); Rs vein marginally curved in apical third. Surface spinules present in all cells of forewing; radular spinules present in m2, reduced in cu1. Legs white to yellow, tarsal segments brown. Meracanthus long, curved laterally, pointed apically. Abdominal tergites brown, sternites white, genitalia yellow. Male paramere long, almost straight posteriorly, widest in the middle, long setae posteriorly visible from lateral view; inner surface with two hooks apically, two to four stout setae basally. Measurements and ratios as in table 2A–C.

Fifth instar larva: colour unknown. Antenna 3-segmented, agellum indistinctly subdivided; segments 1 without a sectaseta, segment 2 with one sectaseta, agellum with ve sectasetae grouped in 2, 2 and 1. Dorsal sclerites covered by sectasetae as large as marginal ones and inconspicuous to short simple setae. Forewing pad with 9 or 10 sectasetae and one or two inconspicuous simple setae marginally; humeral lobe lacking. Caudal plate rounded marginally, apically shallow excavated concavely; sectasetae present dorsally and marginally. Arolium triangular and petiolate, expanded basally. Anus ventral, outer circumanal ring with a single row of pores. Measurements and ratios as in table 3.

Host plants. Trema orientalis (L.) Blume.

Distribution. Philippines (Palawan).

Material examined. HOLOTYPE, Philippines: Palawan, Mt St Paul N. P., Sabang- Cabayugang road, 25 January 1988, Trema orientalis (J. H. Martin) (BMNH) . Dry mounted.

PARATYPES. Philippines: 1, 9 and 4 larvae, same data as holotype ( BMNH, NHMB). Dry and slide mounted .

Comments. P. palawanensis sp. n. is similar to P. setifera (Crawford) from which it is distinguished by the shorter setiferation on body and forewing veins.
