A revision of the genus Jucancistrocerus Blthgen, 1938 from China, with review of three related genera (Hymenoptera: Vespidae: Eumeninae).

In this paper, the genus Jucancistrocerus Blthgen 1938 from China is systematically reviewed, with the first description of the female of J. (Eremodynerus) chotanensis (Blthgen, 1942). Meanwhile, three related genera Eustenancistrocerus Blthgen, Stenancistrocerus de Saussure and Tachyancistrocerus Giordani Soika are briefly reviewed, of which Eustenancistrocerus and Tachyancistrocerus are newly recorded from China. A total of nine species of these four genera from China are illustrated as follows: J. (Eremodynerus) atrofasciatus (Morawitz, 1885), J. (E.) chotanensis (Blthgen, 1942), J. (J.) tachkensis, J. (J.) alashanicus Kurzenko, 1977, J. (J.) angustifrons (Kostylev, 1940), E. (Eustenancistrocerus) askhabadensis (Morawitz, 1885), E. (Parastenancistrocerus) amadanensis amadanensis (de Saussure, 1855), S. (Paratropancistrocerus) transcaspicus (Kostylev, 1934), and T. schmidti (Kokujev, 1912). In addition, a key to the above species is compiled.
