Paurocephala abutili sp. n.

(gures 5A, E, 8G, 36)

Description. Species of the gossypii type.

Adult: head brown, yellow towards genae; vertex covered by inconspicuous setae. Clypeus yellow to brown. Antenna yellow, segments 9 and 10 brown; segment 9 without a long basal seta. Thorax brown and covered by inconspicuous setae dorsally, yellow laterally and ventrally. Metascutellar horn small, blunt apically. Forewing transparent to light yellow; veins yellow, apically brown to forewing margin, base and central part of vein A and central part of vein R brown; base of pterostigma brown. Forewing with inconspicuous setae on veins (vein Rs with 19–23 setae); Rs vein marginally straight, curved in apical third. Surface spinules present in all cells of forewing; radular spinules lacking. Legs yellow, tarsal segments light brown. Meracanthus short, laterally straight, rounded apically. Abdominal tergites brown, sternites and genitalia yellow. Male paramere thin, straight in basal half, tapering in distal half and bend posteriorly, few short setae posteriorly visible from lateral view; inner surface with three to ve peg-like setae situated between basal fth and distal third. Measurements and ratios as in table 2A–C.

Fifth instar larva: colour unknown. Antenna 3-segmented; segments 1 and 2 each with one sectaseta, segment 3 with 7 sectasetae grouped in 3, 3 and 1. Dorsal sclerites covered by sectasetae as large as marginal ones, simple setae lacking. Forewing pad with 18–22 sectasetae marginally; humeral lobe lacking. Caudal plate with large tubercle-like extensions marginally, apical one ending in a long process longitudinally divided; sectasetae present dorsally and marginally. 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. Abutilon mauritianum (Jacq.) Medik. (Malvaceae) .

Distribution. Kenya.

Material examined. HOLOTYPE, Kenya: Nairobi (near National Museum), 5500 ft, 6 January 1972 (C. F. Huggins) ( BMNH). Dry mounted.

PARATYPES. Kenya: 1, 1, same data as holotype; 2, 3, Muguga , August 1953 ( V. F. Eastop); 2, 1, 4 larvae, Chiromo, 22 November 1969, Abutilon mauritianum (H. Schmutterer) ; 1, 2, 2 larval exuvia, Sultan Hamud, 15 May 1988 (J. H. Martin) ( BMNH, NHMB). Dry and slide mounted .

Comments. Similar to P. urenae Russell from which it is distinguished in the adult by the darker body coloration and diVerent antennal shape, and the more slender sectasetae in the larva.
