Paurocephala brevicephala (Crawford)

(gures 31A, 32H, N, 33A, G, 34A) Pauropsylla brevicephala Crawford, 1917: 163 . Lectotype, examined, by present designation. Paurocephala brevicephala (Crawford) ; Crawford, 1919: 150.

Description. Species of the brevicephala type.

Adult: head brown, yellow towards genae; vertex covered by short setae. Clypeus brown. Antenna yellow; segments 7 and 8 with a long basal seta. Thorax brown and covered by inconspicuous setae dorsally, yellow to brown laterally and ventrally. Metascutellar horn short, wide basally, blunt apically. Forewing light brown; veins yellow, apically light brown to forewing margin, vein C1 Sc brown; pterostigma white. Forewing with short setae on veins (vein Rs with 14–19 setae); Rs vein marginally curved throughout. Surface spinules present in all cells of forewing, reduced in c1 sc; radular spinules lacking. Legs including tarsal segments, yellow, femur brown. Meracanthus short, curved laterally, rounded apically. Abdomen brown, genitalia yellow. Male paramere long and slender, widest basally, tapering apically and directed posteriorly, few short setae posteriorly visible from lateral view. Measurements and ratios as in table 2A–C.

Fifth instar larva: colour unknown. Antenna 3-segmented; segment 1 without a sectaseta, segment 2 with one sectaseta and segment 3 with ve sectasetae grouped in 2, 2 and 1. Dorsal sclerites covered by few sectasetae smaller than marginal ones and few lanceolate setae. Forewing pad with 11–13 sectasetae marginally; humeral lobe present. Caudal plate rounded marginally; sectasetae present marginally, few or lacking dorsally with few lanceolate setae. Arolium fan-shaped and petiolate, indistinctly expanded basally. Anus terminal, outer circumanal ring with a single row of pores. Measurements and ratios as in table 3.

Host plants. The material from Palawan has been collected on? Zyzygium sp. (Myrtaceae) which seems an unlikely host.

Distribution. Philippines (Mindanao) ( Crawford, 1917, 1919) (Palawan) and Malaysia ( Sarawak).

Material examined. Philippines: Lectotype and paralectotype, Mindanao, Davao (C. F. Baker); 1 specimen (without abdomen), same data; 14, 22, 55 larvae, Palawan, Inagauan river, 700 m, 31 January 1988,? Zyzygium sp. , ant attended ( Pheidole longipes ) (J. H. Martin). Malaysia: 1, Sarawak, 9 km SW Kapit, Sebadai Park, 50 m, 20 May 1994 (I. Löbl and D. Burckhardt).

Comments. The material from Palawan and Sarawak is only tentatively identi ed as P. brevicephala (Crawford) . It diVers from other species of the brevicephala type in the presence of a basal seta on the last antennal segment in adults. As the antennae are missing in the syntypes of P. brevicephala , the conspeci city of the two remains doubtful. The syntypes have darker forewings with dark brown apices of veins. There is, on the other hand, a good t of the forewing shape between the two. For this uncertainty it is important to stabilize the name brevicephala for which reason a lectotype is designated.
