Material examined.

Holotype female, Papua New Guinea, 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 00680021; BOLD ASQSP084-08; Genbank JF963128) [furthest specimen from pin on topmost card] (USNM)

Paratypes. 4 males and 3 females, 1 unknown (missing metasoma), rest of reared series from the same parasitized host, mounted on total of 3 cards and on same pin as holotype. (USNM).

Morphology.

Length of body 4.0-4.8 mm, of fore wing 3.0-3.6 mm and of antenna 5.1-5.2 mm.

Head. Antenna with 31-32 flagellomeres. Terminal flagellomere acuminate. Median flagellomeres approximately 2 × longer than wide. 3rd segment of maxillary palp of female weakly swollen, approximately 4.5 longer than maximally wide. 5th segment approximately same length as 6th. Base of mandible well removed from eye, closest point approximately 1.3 distance from middle of anterior tentorial pit and eye. Distance between anterior tentorial pits approximately 2.7 × shortest distance between pit and eye. Width of face: width of head across eyes: height of eye = 1.0 : 2.25 : 1.3. Face rather shiny, with fine transverse striation laterally above level of clypeus. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.2 : 1.4. Occipital carina broadly obliterated or extremely weak mediodorsally

Mesosoma. Notauli narrow, moderately impressed, crenulated. Mesoscutum longitudinally striate-rugulose at confluence of notauli. Mesopleuron largely smooth and shiny. Precoxal sulcus deeply impressed and strongly crenulate. Propodeum with very short midlongitudinal carina anteriorly that splits giving rise to pair of weak carinae bordering a widening midlongitudinal depression with moderately well developed transverse striation. Propodeum with distinct mediolateral projections.

Fore wing. Vein 1-CU1 antefurcal. Vein 2-CU1 6.0 × longer than 1-CU1. Vein 1-M weakly curved. Lengths of veins SR1: 3-SR: r = 6.0: 2.7 : 1.0. Vein 2-SR 1.0 × 2-SR+M.

Hind wing. Vein M+CU 0.9 × length of 1-M. Vein 2-SC+R thickened and distinctly inclivous. Vein SR moderately 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 1.7 × longer than posteriorly wide. 2nd metasomal tergite 1.6 × wider than long, with wide midbasal triangular area giving rise to weak midlongitudinal carina; rather weakly irregularly longitudinally striate with approximately 7 striate lateral to midlongitudinal carina. 3rd metasomal tergite 1.9 × wider than long; weakly irregularly longitudinally rugulose-striate basally and medially. 4th - 6th tergite s smooth.

Coloration.

Body, legs, wing venation and antennae largely pale ochreous yellow with malar region, posteroventral part of pronotum, propleuron, mesopleuron and mesosternum, metapleuron, sides of tergites 2-6 and fore and mid coxa, trochanter and trochantellus whitish; terminal 6 or 7 flagellomeres dark grey-black.

Biology.

Gregarious parasitoid of Glyphodes near stolalis.

Etymology.

Based on gregarious biology.
