Description. Species of the psylloptera type.

Adult: head black to dark brown; vertex covered by short setae. Clypeus brown. Antenna brown, segments 1–3 yellow; segment 9 with a long seta in basal quarter. Thorax entirely brown and covered by inconspicuous setae dorsally. Metascutellar horn small, pointed apically. Forewing transparent to white; veins light brown, apically dark brown to forewing margin; pterostigma white. Forewing with inconspicuous to short setae on veins (vein Rs with 18–22 setae); Rs vein marginally curved in apical third. Surface spinules variable, present in all cells of forewing or sparse and absent in c1 sc; radular spinules present in m2, reduced in cu1. Legs yellow to light brown, tarsal segments darker. Meracanthus long, curved laterally, pointed apically. Abdominal tergites brown, sternites including genitalia, yellow to light brown. Male subgenital plate and basal half of female proctiger brown. Male paramere elongate, widest in the middle, apically rounded, few long setae posteriorly visible from lateral view; inner surface with two hooks apically, two to four stout setae in basal third. Measurements and ratios as in table 2A–C.

Fifth instar larva: no material was available for study.

Host plants. Trema orientalis (L.) Blume ( Ulmaceae ).

Distribution. China ( Yang and Li, 1987), Taiwan ( Yang et al., 1986), Japan, Thailand and Malaysia.

Material examined. Taiwan: Paratypes (of P. trematos ) 3, 3, Taichung, Takeng, 1 April 1986, Trema orientalis (M. M. Yang) . Japan: 1, 2, Ryu-Kyu riomote, S Hoshidate, 50 m, 7 October 1994 (C. Lienhard). Thailand: 2, 3, Lampang, Doi Mae Tho, 21 April 1998 (K. Matsumoto). China: Holotype (of P. tremae ), paratypes 2, 2, Fujian, Fuzhou, 21 October 1974, Trema orientalis ; Holotype (of P. guanxiensis ) and paratypes 2, 2, Guingxi, Liu-zhou, 9 June 1982, Trema orientalis ; 1, Hong Kong, Lantau, SW Peninsula, Shek Pik, 20 October 1990, Trema ? orientalis (J. H. Martin) . Malaysia: 6, 17, Sarawak, Gunong Mulu N. P., Base Camp Helipad, 17–30 September 1977, Trema sp. (D. Hollis) (BMNH, BAUC, MNHG, NCHU). Dry and slide mounted.

Comments. The material from Thailand and Japan agrees with type material of P. trematos Yang et al. The material from Sarawak is teneral and the coloration diVers. Also the extent and density of surface spinules on forewing is diVerent (gure 21E, F). Most of the material from China has longer setae on forewing venation. The mentioned characters are variable in this species .
