Material examined.

Holotype female, Papua New Guinea, East Sepik Province, Yapsiei, 27-Jan-04, 141°05.839'E, 4°37.695'S, 100m, (voucher USNM ENT 00454207; BOLD ASQSP061-08; Genbank JF271312) [mounted on same pin is a pupal case, presumably of the host species, though not the host of this individual]

Paratypes. 1 male, East Sepik Province, Yapsiei, 27-Feb-04, 141°05.839'E, 4°37.695'S, 100m (voucher USNM ENT 00454275; BOLD ASQSP064-08; Genbank JF271310); 1 male, East Sepik Province, Yapsiei, 18-Feb-04, 141°05.839'E, 4°37.695'S, 100m (voucher USNM ENT 00454148; BOLD ASQSP062-08; Genbank JF271311)

Morphology.

Length of body 11 mm, of fore wing 8.7 mm and of antenna 11 mm.

Head. Antenna with 57 flagellomeres. Terminal flagellomere distinctly acuminate. Median flagellomeres 1.8 × longer laterally than wide. 3rd segment of maxillary palp of female very weakly swollen medially swollen, approximately ?7 × longer than maximally wide. 5th segment approximately 0.65 length of 6th. Base of mandible very close to eye, closest point approximately 0.8 distance from middle of anterior tentorial pit and eye. Distance between anterior tentorial pits approximately 5.0 × shortest distance between pit and eye. Width of face: width of head across eyes: height of eye = 1.0 : 2.7: 1.9. Face largely finely transversely striate. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0 : 3.0 : 1.1. Occipital carina well developed, complete mediodorsally.

Mesosoma. Notauli weakly impressed anteriorly, dorsally represented by converging lines of discrete pits. Mesoscutum smooth where notauli converge. Propodeum with complete midlongitudinal carina.

Fore wing. Vein 1-CU1 postfurcal. Vein 2-CU1 8.5 × longer than 1-CU1. Lengths of veins SR1: 3-SR: r = 4.6: 3.2:1.0. Vein 2-SR 2.4 × 2-SR+M.

Hind wing. Vein M+CU 2.0 × length of 1-M. Hind wing vein 2-SC+R very thickened, almost quadrate. Vein SR gently curving basally and gradually getting closer to anterior margin towards wing tip.

Metasoma. 1st metasomal tergite 2 × 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 12 striae lateral to midlongitudinal carina. 3rd metasomal tergite 1.4 × wider than long; longitudinally striate, with midlongitudinal carina distinct on anterior 0.5. 4th and 5th tergites finely longitudinally striate medially becoming weakly punctate-striate laterally

Coloration.

Head, and tergites 2-4 entirely, and anterior half of tergite 5 black, hind tibia dark brown, mesosoma, 1st tergite and legs orange red, metasomal tergite 5 posteriorly cream-white, tergites 6 and 7 largely cream-white. Antenna largely black with paler brown zone approximately occupying flagellomeres 27-42. Wing membrane largely pale brown, venation largely (except more basal veins, dark brown; pterostigma dark brown.

Biology.

Solitary endoparasitoid of Meekiaria ( Crambidae ) caterpillars on Psychotria sp. ( Rubiaceae ). Meekiaria have distinctive male genitalia with numerous closely related species in PNG ( Munroe 1974, Craft et al. 2010: S2).

Etymology.

Named after Nicholai Miklucho-Maklaj, a Russian explorer of New Guinea who lived around the Madang area for some time.
