Paurocephala insolita sp. n.

(gures 6E, J, 7C, F, I, L, 8L, 35)

Description. Species of the gossypii type.

Adult: head and clypeus white; vertex covered by short setae. Antenna white, apical half of segments 4, 6 and 8 and entire segments 9 and 10 brown; segment 9 without a long basal seta. Thorax white to light brown and covered by inconspicuous setae dorsally, laterally and ventrally white. Metascutellar horn small, blunt apically. Forewing whitish; veins light yellow, apically brown to forewing margin, central part of veins A, R1 M1 Cu1, R and M1 Cu1 brown, apical third of Rs vein brown; pterostigma brown basally and apically. Forewing with inconspicuous setae on veins (vein Rs with 12–16 setae); Rs vein marginally curved in distal third. Surface spinules present in all cells of forewing; radular spinules lacking. Legs including tarsal segments, white to yellow. Meracanthus short, almost straight laterally, rounded apically. Abdominal tergites light brown, sternites white, genitalia brown. Male paramere almost straight posteriorly, widest in the middle and tapering apically, few long setae in basal half posteriorly visible from lateral view. Measurements and ratios as in table 2A–C.

Fifth instar larva: antenna yellow, base and apical third of agellum brown; 3-segmented, segment 1 without a sectaseta, segment 2 with one sectasetae and segment 3 with ve sectasetae grouped in 2, 2 and 1. Dorsal sclerites brown, covered by sectasetae as large as marginal ones and few inconspicuous simple setae. Wing pads yellow, brown apically and basally; forewing pad with ve to seven sectasetae and one to three inconspicuous simple setae marginally; humeral lobe lacking. Caudal plate yellow to light brown, marginally darker, with large tubercle-like extensions marginally, ending in a rounded process, V-shaped excavated apically; sectasetae present dorsally and marginally with few inconspicuous simple 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. Psorospermum febrifugum Spach (Clusiaceae) .

Distribution. Angola.

Material examined. HOLOTYPE, Angola: Gabela , 18 September 1971, Psorospermum febrifugum (A. van Harten) (BMNH) . Dry mounted.

PARATYPES. Angola: 8, 21 and 16 larvae, same data as holotype ( BMNH, NHMB). Dry and slide mounted and preserved in alcohol .

Comments. Similar to P. lienhardi from which it diVers in the absence of bi d setae on the antennae and in the shape of the male paramere. P. insolita is the only member of Paurocephala whose host plant is outside the Malvales .
