Five species of
Wang Z-T, Li C-D (2021) Three new species, and new distributional data, of
The genus
Specimens were collected by using sweep nets, yellow pan traps and Malaise traps, and glued to triangle cards. Photographs were taken with a digital CCD camera attached to an AOSVI Hk830 microscope. Relative measurements and total body lengths were measured using an eye-piece reticle in the ocular of the microscope. All the specimens examined were deposited in the insect collections at Northeast Forestry University (
The following abbreviations are used in the text:

|
– | Apex of mesoscutellum emarginate forming two distinct teeth (Figs |

2 | Forewing with two blackish bands, marginal vein 0.25× as long as submarginal vein; metasoma fusiform, a little longer but not narrower than mesosoma |

– | Forewing without blackish bands, marginal vein half as long as submarginal vein; metasoma elongate-oval, a little narrower but hardly longer than mesosoma |

3 | Metasoma with more than two basal carinae on Gt1 (Figs |

The specific name is derived from the name of the collection locality of the holotype.
The new species is similar to
The new species is characterized by two diverging teeth of the mesoscutellum, a unique propodeum and the scrobe not reaching the anterior ocellus. A female holotype would be preferable but we failed to collect female specimens. However, most likely the female will share at least part of the differences listed for the male holotype.
Body mostly black (Fig.
Unknown.
China (Heilongjiang).
Two paratypes differ from the holotype by having black eyes, but no other significant differences were found in the available material.
Latin:
Compared with other species of this genus, the new species differs by having dense and long setae on its eyes (Fig.

Our specimens agree well with the original description except for the colour of the antenna and metasoma. This is the first record from Henan, Hainan and Yunnan Provinces, China.

Our specimens agree well with the original description except for slight colour differences of the teeth of the mesoscutellum. This is the first record from continental China.
