Paratypes: 5 females, 2 males, from same brood as holotype, mounted on 3 cards on same pin; 6 females, 3 males mounted on 2 cards on same pin, Madang Province, Wanang, 10-May-06, 145°10.910'E, 5°13.853'S, 100m, ex caterpillar on Ficus variegata Blume, (voucher USNM ENT 00680061; BOLD ASQSP081-08; Genbank JF271301); 9 fe males, 3 males, mounted on three cards on same pin, Madang Province, Wanang, 24-May-07, 145°10.910'E, 5°13.853'S, 100m, ex caterpillar on Ficus variegata Blume, Moraceae , (voucher USNM ENT 00680102; BOLD ASQSP083-08; Genbank JX034721) [host Glyphodes near stolalis]; 10 individals, Madang Province, Wanang, 10-May-06, 145°10.910'E, 5°13.853'S, 100m, ex caterpillar on Ficus variegata Blume, Moraceae , (voucher USNM ENT 00680111; BOLD ASQSP139-08; Genbank JX034722).

Morphology.

Length of body 4.3-5.5 mm, of fore wing 3.0-4.1 mm and of antenna 4.5-5.0 mm.

Head. Antenna with 35-39 flagellomeres. Terminal flagellomere acuminate. Median flagellomeres 2.3 × longer than wide. 3rd segment of maxillary palp of female slender, approximately 7 longer than maximally wide. 5th segment slender and approximately same length of 6th. Base of mandible well separated from eye, closest point approximately 1.1 distance from middle of anterior tentorial pit and eye. Distance be tween anterior tentorial pits approximately 5.2 × shortest distance between pit and eye. Width of face: width of head across eyes: height of eye = 1.0 : 2.25 : 1.36. Face laterally with well developed transverse rugosity. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.0 : 1.0. Occipital carina complete but distinctly weak mediodorsally

Mesosoma. Notauli more or less strongly impressed and crenulated. Mesoscutum rugulose at confluence of notauli. Mesopleuron largely smooth and shiny. Precoxal sulcus strongly impressed, weakly sinuate, strongly finely crenulated. Propodeum with short midlongitudinal carina anteriorly that splits giving rise to a widening midlongitudinal depression with moderately well developed transverse striation.

Fore wing. Vein 1-CU1 antefurcal. Vein 2-CU1 7 × longer than 1-CU1. Vein 1-M weakly curved. Lengths of veins SR1: 3-SR: r = 4.5:2.7:1.0. Vein 2-SR 2.8 × 2-SR+M.

Hind wing. Vein M+CU 0.6 × length of 1-M. Vein 2-SC+R thickened, distinctly inclivous. Vein SR weakly curved on basal half, getting closest to wing margin approximately 0.6 distance to wing tip, then running more or less parallel to wing margin.

Metasoma. 1st metasomal tergite 1.4 × longer than posteriorly wide. 2nd metasomal tergite 1.35 × wider than medially long, with well developed midbasal triangular area giving rise to complete midlongitudinal carina; irregularly longitudinally striate with approximately 8 striate lateral to midlongitudinal carina. 3rd metasomal tergite 1.9 × wider than long; longitudinally striate, without distinct midlongitudinal carina. 4th tergite distinctly irregularly longitudinally striate, 5th tergite more weakly striate and largely only on basal 0.5; 6th tergite smooth.

Coloration. Body largely brown yellow, metasoma somewhat more reddish; antennae largely cream white, darkening to blackish near tip; fore legs entirely, mid- and hind legs from apex of coxa white. Wing membrane hyaline, venation largely brown, pterostigma largely brown, paler at base.

Etymology. Named in reference to the province where specimens were reared.

Biology. Gregarious parasitoid of Glyphodes near stolalis Guenee 1854, caterpillars: the broods reared comprised members of both sexes. Glyphodes near stolalis is a member of a species complex needing revision ( Munroe 1996: 280), complicated by the type of stolalis being lost ( Viette 1987) ( Hrcek et al. 2011: supplement).
