Distinctaleyrodes setosus sp. nov.

( Figs. 1–4 )

PUPARIUM ( Fig. 1 ). Pale, with secretion of white wax; asymmetrically elongate, slightly curved and constricted at caudal end, 1.28–1.68 mm long, 0.40–0.56 mm wide. Found singly on the under surface of leaves, mostly along mid vein of leaf.

Margin. ( Fig. 2 ). Crenulate, 2–3 crenulations in 0.1 mm; submarginal striations present; thoracic tracheal pore faintly indicated in the margin while caudal tracheal pore indicated by deep invagination. Anterior marginal setae absent and posterior marginal setae 18 m long.

Dorsum. Tuberculate, submargin with a row of small striations. Longitudinal moulting suture faintly discernible and reaching margin and transverse moulting suture reaching submargin. A row of tubercles on outer submedian area from base of cephalic submarginal setae to posterior caudal end distinct. Median tubercles absent and submedian depressions on abdominal segments faintly discernible. Seventh abdominal segment very short.

Chaetotaxy. Two pairs of submarginal setae­ first pair arising anteriorly in cephalic end on tubercle, 330 m long and second pair arising from caudal end, 112 m long. 10 pairs of subdorsal setae on the submedian area with distinct bases ( Fig. 3 ), 43–70 m long, 5 pairs on cephalothorax (one pair each on pro­, meso­ and metathorax on submedian area and one pair each on meso and metathorax on subdorsal area and five pairs on abdomen (one pair on inner submedian area of first abdominal segment and four pairs on outer submedian area of abdominal segments III–VI), eighth abdominal setae 17 m long; six pairs of subdorsal minute setae, 13–15 m long, one pair each on prothorax, metathorax, second abdominal segment and three pairs laterad of caudal furrow. Vasiform orifice ( Fig. 4 ) subcircular, 56–60 m long, 50–58 m wide; operculum subcircular, 20–30 m long, 20–36 m wide. Lingula exposed. Caudal furrow with faint tubercles, 196 m long, 20 m wide at its widest end. Pores and porettes evident.

Ven te r. Paired ventral abdominal setae 38 m long, 38 m apart. Antennae reaching base of mesothoracic legs. Thoracic and caudal tracheal folds not indicated. MATERIAL EXAMINED. Holotype puparium, INDIA, Karnataka: Kudremukh National Park, on Derris sp., 7.viii.2001 (A.K. Dubey) (FRI).

Paratypes: 8 puparia, data as holotype (ANIC, BMNH, IARI, NMNH, NTU, SMTD, USDA, ZMU).
