Description. Species of the psylloptera type.

Adult: material at hand is teneral and unless otherwise stated overall body colour is white to yellow. Vertex covered by short setae. Antenna white, apical half of segments 4, 6 and 8 and entire segment 9 and 10 brown; segment 9 without a long basal seta. Thorax covered by inconspicuous setae dorsally. Metascutellar horn small, pointed apically. Forewing whitish; veins light yellow, apically brown to forewing margin. Forewing with long setae on veins (vein Rs with 13–22 setae); Rs vein curved in apical half. Surface spinules present in all cells of forewing; radular spinules present in m2, reduced in cu1. Legs white, tarsal segments brown. Meracanthus long, curved laterally and pointed apically. Male paramere long, widest in the middle, rounded apically, long setae posteriorly visible from lateral view; inner surface with two hooks apically, one to three stout setae basally. Measurements and ratios as in table 2A–C.

Fifth instar larva: antenna yellow to light brown, apical third of agellum brown; 3-segmented, agellum indistinctly subdivided; segment 1 without a sectaseta, segment 2 with one sectaseta, agellum with ve sectasetae grouped in 2, 2 and 1. Dorsal sclerites brown, covered by sectasetae as large as marginal ones with few inconspicuous simple setae. Wing pads light brown, basally darker; forewing pad with seven to nine sectasetae and one to three inconspicuous simple setae marginally; humeral lobe lacking. Caudal plate brown, with shallow tubercle-like extentions marginally, apically strongly excavated concavely; sectasetae present dorsally and marginally with few inconspicuous setae. 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 ( Ulmaceae ).

Distribution. Bangladesh.

Material examined. HOLOTYPE, Bangladesh: Koitta Manikgonj , 25 March 2000, Trema orientalis (Z. Islam) (BMNH) . Dry mounted.

PARATYPES. Bangladesh: 3, 4 and 4 larvae, same data as holotype; 1 and 2 larvae same data but 15 February 2000 (A. Polaszek) ( BMNH, NHMB) .
