Material examined.

Holotype female, Papua New Guinea, East Sepik Province, Wamangu, 11-Mar-05, 143°39.125'E, 03°47.228'S, 100m, PSS, ex caterpillar on Psychotria micrococca (Laut. & Schum.) Val. ( Rubiaceae ) (voucher USNM ENT 00505491; BOLD ASQSP060-08; Genbank JF271303)

Morphology.

Length of body 10.0 mm, of fore wing 8.5-9.5 mm and of antenna 9.5-11.2 mm.

Head. Antenna with 56 flagellomeres. Terminal flagellomere strongly acuminate. Median flagellomeres 2 × longer laterally than wide. 3rd segment of maxillary palp of female moderately swollen, approximately 4 longer than maximally wide. 5th segment approximately 0.9 length of 6th. Base of mandible close to eye, closest point approximately 0.75 distance from middle of anterior tentorial pit and eye. Distance between anterior tentorial pits approximately 6 × shortest distance between pit and eye. Width of face: width of head across eyes: height of eye = 1.0 : 3.1 : 2.0. Face with a smooth triangular area above clypeus bordered by well developed transverse striation that more or less meets medially at level of antennal sockets. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 2.0: 1.2. Occipital carina complete, rather wavy when viewed laterally.

Mesosoma. Notauli weakly impressed anteriorly, dorsally represented by converging lines of discrete pits. Mesoscutum smooth where notauli converge. . Mesopleuron almost entirely smooth ad shiny, precoxal sulcus weakly impressed, unsculptured. Propodeum with complete strong midlongitudinal carina.

Fore wing. Vein 1-CU1 postfurcal. Vein 2-CU1 9.0 × longer than 1-CU1. Lengths of veins SR1: 3-SR: r = 4.8 : 3.5 : 1.0. Vein 2-SR 2.0 × 2-SR+M.

Hind wing. Vein M+CU 1.7 × length of 1-M. Vein SR gently curving basally and gradually getting closer to anterior margin towards wing tip.

Metasoma. 1st metasomal tergite 2.1 × longer than posteriorly wide. 2nd metasomal tergite 1.1 × longer than maximally wide, with well developed midbasal triangular area giving rise to complete midlongitudinal carina; irregularly longitudinally striate with approximately 11 striate lateral to midlongitudinal carina. 3rd metasomal tergite 1.2 × wider than long; longitudinally striate. 4th tergite largely longitudinally striate. 5th tergite longitudinally striate medially becoming smooth laterally with punctures. 6th tergite entirely smooth and punctate.

Coloration.

Head, and tergites 2-4 entirely, anterior half of tergite 5, and extreme base of tergite 6 black, hind tibia dark brown, hind trochanter and trochantellus dark brown, mesosoma, 1st tergite and rest of legs orange red, metasomal tergites 4 and 5 posteriorly cream-white, tergites 6 and 7 largely cream-white. Antenna largely black with paler brown zone approximately occupying flagellomeres 22-39. Wing membrane largely pale brown, venation largely (except more basal veins, dark brown; pterostigma dark brown.

Etymology.

Pukpuk in Melanesian Pidgin means crocodile, a favourite of the indigenous people living around Sepik river.

Biology.

Unknown.
