Genus Mongoloraphidia H. Aspöck & U. Aspöck, 1968

Mongoloraphidia H. Aspöck & U. Aspöck, 1968: 59 . Type species: Agulla sororcula H. Aspöck & U. Aspöck, 1966: 226 (original designation).

Diagnosis. Mongoloraphidia can be diagnosed by the absence of the complex of gonocoxites, gonapophyses, and gonostyli 10 and the reduction of the anterior part of the ectoproct in the male genitalia.

Distribution. China, India, Japan, Kazakhstan, Khabarovsk, Kyrgyzstan, Mongolia, Pakistan, Russia, Tajikistan, Turkmenistan, Uzbekistan.
