Holotype. NIGP174881 View Materials , female. Well-preserved wasp, partly obscured with air bubbles.

Material. Holotype only.

Etymology. The species is named in honor of Professor Alexander P. Rasnitsyn.

Diagnosis. Fore wing with r-rs issuing before pterostigmal midlength, twice as long as distance between r-rs and m-cu; 2m-cu reclined; hind wing with 2-Rs and 2-M reaching wing margin.

Description. Head broad, with eyes set wide apart. Antennae filiform, robust, 0.6× as long as wing length; scape cylindric, robust, pedicel slightly longer than wide, 0.3× as long as scape; flagellomeres gradually shortening from base to apex, and apical segment as long as subapical one. Mandible robust, gradually curved.

Hind wing with 5 distal hamuli; 2-Rs and 2-M reaching wing margin; 1-Rs 0.1× as long as r-m; 1-M 1.3× as long as r-m.

Propodeum with strong longitudinal carination. 1- st metasomal tergite with strong longitudinal carinae; posterior tergites with rough longitudinal sculpture. Ovipositor spear-shaped, serrated, 0.3× as long as fore wing length.
