DISTRIBUTION — Papua New Guinea.

DESCRIPTION — MALE: Fully winged; length 1.9-2.5 mm (holotype 2.1 mm). Head black, except mandible testaceous; antenna brown-testaceous, except segments 1-3 testaceous; mesosoma black; metasoma brown, partly testaceous; legs testaceous. Antenna filiform; antennal segments in following proportions: 9:4:6.5:5:5:5:4.5:5:5:7. Head shiny, strongly punctate and with irregular longitudinal keels and areolae; face with large punctate area in front of anterior ocellus; frontal line complete; face with two lateral keels around orbits directed towards antennal toruli; occipital carina complete; POL = 6; OL = 4; OOL = 4.5; OPL = 4; TL = 2; greatest breadth of posterior ocelli longer than TL (3:2). Scutum, scutellum and metanotum shiny, finely punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 × length of scutum. Propodeum reticulate rugose, with a distinct transverse keel between dorsal and posterior surface; posterior surface with two longitudinal keels, lateral areas rugose and median area shiny, partly unsculptured, except areolae along margins. Forewing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (2:8). Paramere (Figure 6) with distal inner rounded process, without dorsal proximal membranous process. Tibial spurs 1/1/2.

FEMALE: Unknown.

ETYMOLOGY — The species is named after Mt. Wilhelm, where all paratypes have been collected.

HOSTS — Unknown.

REMARKS — A. wilhelmense is similar to A. luctuosum Olmi, 1984 and A. hageni Olmi, 1984 , but with paramere provided with an inner rounded distal process (Figure 6) while process is absent in both other species (Figures 4, 5). The new species can be included in the key to the males of the Australasian Anteon published by Olmi (1984) by replacing couplet 11 as follows:

11 Paramere with distal inner rounded process (Figure 6) ........................................................... wilhelmense n. sp. – Paramere without distal inner rounded process (Figures 4, 5) ............................................................................. 11’

11’ Head completely reticulate rugose .................................................................................................. luctuosum Olmi – Head with face sculptured by numerous longitudinal keels ................................................................ hageni Olmi
