Paurocephala boehmeriae sp. n.

(gures 22C, 23H, 24K, 25H, 27A, 28H, M, 43)

Description. Species of the psylloptera type.

Adult: head brown, vertex with a pair of yellow spots along base of coronal suture; vertex covered by short setae. Clypeus brown. Antenna yellow, apex of segments 4 and 6 and entire segments 8–10 brown; segment 9 without a long basal seta. Thorax brown with yellow markings along body axis and covered by short setae dorsally, brown to light brown laterally and ventrally. Metascutellar horn small, pointed apically. Forewing transparent; veins light brown; pterostigma white, often with a central transparent area. Forewing with inconspicuous setae on veins (vein Rs with 13–21 setae); Rs vein marginally curved in apical half. Surface spinules con ned to cells in apical half of forewing; radular spinules present in m2, reduced in cu1. Legs white to yellow, tarsal segments dark brown. Meracanthus long, curved laterally, pointed apically. Abdominal tergites dark brown, sternites white, genitalia yellow to brown. Male paramere long and straight posteriorly, widest in the middle, rounded apically, numerous long setae posteriorly visible from lateral view; inner surface with two hooks apically, two to ve stout setae in basal quarter. Measurements and ratios as in table 2A–C.

Fifth instar larva: antenna yellow, distal third of agellum brown; indistinctly 5-segmented; segment 1 without a sectaseta, segment 2 with one sectaseta, agellum with ve sectasetae grouped in 2, 2 and 1. Dorsal sclerites light brown, covered by sectasetae as large as marginal ones and few inconspicuous simple setae. Wing pads yellow to light brown; forewing pad with eight or nine sectasetae and one or two inconspicuous simple setae marginally; humeral lobe lacking. Caudal plate brown, elongate with small tubercle-like extensions marginally, apical one ending in a relatively long process excavated V-shaped apically; sectasetae present dorsally and marginally. Arolium triangular and petiolate, distinctly expanded basally. Anus ventral, outer circumanal ring with a single row of pores. Measurements and ratios as in table 3.

Host plants. Boehmeria nivea (L.) Gaudich ( Urticaceae ).

Distribution. China ( Hong Kong).

Material examined. HOLOTYPE, China: Hong Kong , Lantau, Tung Chung, 26 November 1999, Boehmeria nivea (J. H. Martin) (BMNH) . Dry mounted.

PARATYPES. China: 25, 30 and numerous larvae, same data as holotype ( BMNH, NHMB). Dry and slide mounted and preserved in alcohol .

Comments. Adult P. boehmeriae sp. n. are similar to P. sauteri (Enderlein) but diVer in the absence of a long basal seta on antennal segment 9. The larva resembles that of P. setifera (Crawford) from which it can be best separated by the diVerent host plant.
