Paratypes: 1 female, Papua New Guinea, Madang Province, Wanang, 16-Feb-2007, 145°10.910'E, 5°13.853'S, 100m, ex caterpillar feeding on Merremia peltata (L.) Merr. ( Convolvulaceae ) (voucher USNM ENT 00680134; BOLD ASQSP135-08; Genbank JF963127); 1 female, Papua New Guinea, Madang Province, Wanang, 20-Jun-06, 145°10.910'E, 5°13.853'S, 100m, ex caterpillar feeding on Merremia peltata (L.) Merr. ( Convolvulaceae ) (voucher USNM ENT 00680173, no sequence data).

Morphology.

Length of body 6.0-8.5 mm, of fore wing 5.0-6.5 mm and of antenna 8.0-8.5 mm.

Head. Antenna with 45 flagellomeres. Terminal flagellomere strongly acuminate. Median flagellomeres approximately 2.5 × longer than wide. 3rd segment of maxillary palp of female swollen, approximately 4.0 longer than maximally wide. 5th segment reduced, approximately 0.5 length of 6th. Base of mandible separated from eye by approximately same distance as from middle of anterior tentorial pit and eye. Distance between anterior tentorial pits approximately 4.0 × shortest distance between pit and eye. Width of face: width of head across eyes: height of eye = 1.0 : 2.5 : 1.6. Face weakly transversely to obliquely striate dorsolaterally. 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 narrowly obliterated medially

Mesosoma. Notauli moderately deep, narrow and crenulated, uniting shortly before posterior of mesoscutum. Mesoscutum with distinct narrow midlongitudinal groove posteriorly. Propodeum with midlongitudinal carina at least on anterior 0.5, posteriorly either complete with strong transverse rugae lateral to it, or replaced by transverse rugosity.

Fore wing. Vein 1-CU1 postfurcal. Vein 2-CU1 18-19 × longer than 1-CU1. Lengths of veins SR1: 3-SR: r = 4.5 : 2.7 : 1.0. Vein 2-SR 2.1 × 2-SR+M.

Hind wing. Vein M+CU 1.1 × length of 1-M. Vein 1-SC+R slightly thickened, almost transverse. Vein SR strongly curved on basal half, almost reaching wing margin approximately half distance to wing tip, then running more or less parallel to wing margin.

Metasoma. 1st metasomal tergite 2.0 × 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 6 striate lateral to midlongitudinal carina. 3rd metasomal tergite 1.1 × longer than maximally wide; longitudinally striate. 4th and 5th tergites longitudinally striate. 6th tergite smooth.

Coloration.

Body.

Etymology.

Named because of its parasitism of Crambidae .

Biology.

Solitary endoparasitoids of Crambidae feeding on Merremia peltata (L.) Merr. ( Convolvulaceae ). The holotype was reared from Hydriris guadealis Rothschild. Paratype USNM ENT 00680134 was reared from Tabidia insanalis Snellen, and paratype USNM ENT 00680173 was reared from.a further unidentified crambid.
