Treatment

Material examined. JAPAN. Hokkaido I.: 1 ♀ ( EUM) Sapporo, Usubetsu, 42.9348°N, 141.1206°E, small stream, Malaise trap, 29.IV–24. GoogleMaps V.2012, coll. N. Kuhara.

Additional material. Honshu I.: 1 ♀ ( EUM) Aomori, Nishimeya-mura, Kawaratai , 43°31’N, 141°10’E, Malaise trap, 21–30.VI.2013, coll. T. Nakamura GoogleMaps .

Diagnosis. Flagellum short, with17–18 short flagellomeres.Mesopleuron entirely granulate, with weak punctures centrally; foveate groove absent or indistinct. Metacarpus short, not reaching tip of the wing. First metasomal tergite slender, polished. Second tergite slightly elongate. Ovipositor sheath distinctly shorter than first tergite.

Variation. Malar space in Japanese specimens 0.7–0.8× as long as basal mandibular width. Female from Honshu I. has metacarpus long and reaching tip of the wing, vein 2rs-m short and thick, and mesopleuron centrally nearly smooth and finely punctate. Thus, this specimen may represent either an undescribed species or variation of T. impunctator .

Distribution. Russian Far East; in Japan known from Hokkaido I. and probably from Honshu I. First record from Japan.
