Paurocephala artocarpae Braza and Calilung

( gures 13B, 14B, 15B, H, 16B, 39) Paurocephala artocarpae Braza and Calilung, 1981: 336 . Holotype, Philippines: Luzon , Los

Baños (near Laguna), 10 January 1976, Artocarpus blancoi (A. B. Bragado) (UPPC) , not examined .

Description. Species of the wilderi type.

Adult: head yellow to brown; vertex covered by long setae. Clypeus yellow. Antenna yellow, segments 4 and 6, apical half of segment 8 and entire segments 9 and 10 brown; segment 9 without a long basal seta. Thorax yellow to light brown and covered by long setae dorsally, light brown to white laterally and ventrally. Metascutellar horn small, blunt apically. Forewing light brown; veins brown; pterostigma white to light brown. Forewing with long setae on veins (vein Rs with 18–23 setae); Rs vein marginally curved throughout entire length. Surface spinules present in all cells of forewing; radular spinules present in m2, reduced in cu1. Legs white to yellow, tarsal segments light brown. Meracanthus long, straight laterally, rounded apically. Abdomen including genitalia, light brown. Male paramere long and straight posteriorly, widest in the middle and tapering apically, few short setae posteriorly visible from lateral view; inner surface with two hooks apically and rows of stout setae con ned posteriorly in basal half. Measurements and ratios as in table 2A–C.

Fifth instar larva: antenna yellow to light brown; 3-segmented, agellum indistinctly subdivided; segment 1 and 2 without sectasetae, agellum with ve sectasetae grouped in 2, 2 and 1. Thoracic tergites yellow to light brown; abdominal tergites brown. Dorsal sclerites covered by sectasetae and simple setae as large as marginal ones. Wing pads yellow to white, brown towards thorax; forewing pad with three to six sectasetae and four to eight simple setae marginally; humeral lobe lacking. Caudal plate yellow, rounded marginally; sectasetae present dorsally and marginally. Arolium triangular and petiolate, expanded basally. Anus terminal, outer circumanal ring with a single row of pores, subdivided at irregular intervals. Measurements and ratios as in table 3.

Host plants. Artocarpus blancoi (Elm.) Merr. (Moraceae) ( Braza and Calilung, 1981).

Distribution. Philippines (Luzon) ( Braza and Calilung, 1981), Malaysia (Sabah) and Indonesia (Sulawesi).

Material examined. Philippines: 2, 2, Luzon, Los Baños (near Laguna), 10 January 1976, Artocarpus blancoi (R. D. Braza) . Indonesia: 14, 13 and numerous larvae, Sulawesi, Sulawesi Utara, Dumoga-Bone N. P., Mogogonipa Gunung , ca 400–500 m, 8 April 1985, Artocarpus sp. , ant attended (J. H. Martin); 2, same data but 6–13 July 1985 and 2– 9 October 1985 (yellow pan traps); 2, same data but ca 900 m, Clark’s Camp ridge, 13 April 1985 . Malaysia: 2, Sabah, Poring Hot Springs , 500 m, 6 May 1987 (D. Burckhardt and I. Löbl) ( BMNH, NHMB). Dry and slide mounted and preserved in alcohol .

Comments. Type material was unavailable for study but material collected with the type series was examined. The material from the Philippines has a straight vein M1+2 which is directed away from apical part of vein Rs while the material from Sabah and Sulawesi has a marginally curved vein M1+2 which is parallel to the apical part of Rs vein. This diVerence is here considered as intraspeci c variation .
