Genus Neurateles Ratzeburg, 1848

Neurateles Ratzeburg, 1848: 86 . Type species: Neurateles papyraceus Ratzeberg, 1848 . Monobasic.

Diagnosis. Lower edge of clypeus straight or slightly concave ( Fig. 5 ). Labrum narrowly exposed ( Fig. 5 ). Face and clypeus not divided by supraclypeal suture ( Fig. 5 ). Face convex in lateral view. Upper edge of face without a projection over or between the antennal sockets ( Fig. 5 ). Apex of both mandibular teeth overlapping each other ( Fig. 5 ). Lower tooth of mandible obvious, distinctly shorter than upper tooth. Scape long and subcylindric, more than 1.8 times as long as wide. Epicnemial carina absent ( Fig. 9 ) or present laterally by some weak wrinkles. Propodeum without pleural carina and area postero ( Figs. 9 , 10). Fore wing without an areolet ( Fig. 2 ). Metasoma weakly sculptured and elongate, its posterior part strongly compressed and its shape is blade-like in female ( Figs. 1, 3, 4 ). Spiracle of T 1 definitely placed in front of the midlength ( Fig. 9 ). Ovipositor fairly long, longer than apical depth of metasoma, weakly upcurved ( Fig. 3 ) or straight. Ovipositor sheath covered with sparse hairs its entire length.

Distribution. Holarctic region. Although Townes (1971) referred that this genus occurs in the Neotropical region, no species has been described from this region.
