Male
Length, 4.8 mm.; fore wing, 4.3 mm.

Head transversely elliptical, nearly one and one-third times as broad as long, with concave occipital surface and resembling the head of a dipteron. Antennae inserted a little below the middle of the face. Clypeus as long as broad, subtriangular, moderately convex in the middle, with nearly straight anterior border. Frontal groove distinct anteriorly, posteriorly continued back as a rather deep impression to the anterior ocellus. Antennal scapes about two and one-half times as long as broad, cylindrical, broader than the funiculi; first joint of the'latter a little longer than broad; joints 2-9 slender and elongate, gradually diminishing in length distally; joints 10 and 11 subequal, together as long as the preceding and terminal joint. Thorax about twice as long as broad, broadest through the mesonotum; pronotum transversely swollen; mesonotum and scutellum convex; epinotum' evenly rounded and sloping, without distinct base and declivity. Petiole higher than long, the node thick, higher than broad, broader above than below, cuneate in profile, with subequal, flat anterior and posterior surfaces and blunt apex. Gaster elliptical, the first segment high and subtruncate anteriorly; external genital valves subquadrate, with broad excised apical border.

Head subopaque, very finely punctate-reticulate; thorax, petiole and gaster more shining, superficially and very finely punctate. Mayrian furrows on the mesonotum transversely rugose.

Hairs yellowish, short, rather few and scattered on the thorax, more numerous on the border of the petiolar node and on the gaster, especially on the venter. Whole body and appendages covered with very fine, appressed whitish pubescence, not very conspicuous or sufficiently dense to hide the underlying integument.

Brownish black; mandibles, mouthparts, tarsi and articulations of legs dull brownish yellow. Wings uniformly tinged with brown, with brown stigma and veins.

Type Material
Described from a single specimen taken during December, 1907, by Dr. F. Muir, on the Island of Larat, near New Guinea.
