Berlese's Primitive Oribatid Mites Author van der Hammen, L. text Zoologische Verhandelingen 1959 40 1 93 http://www.repository.naturalis.nl/document/148866 journal article ORI111 0DC6B575-3CB3-41C1-A3EC-850520AE4487 Masthermannia Berlese, 1913 Masthermannia Berlese, 1913, p. 100. Posthermannia Grandjean, 1954c, p. 298. The original diagnosis of the genus is insufficient, and Berlese's description and figure of the type-species ( Angelia mammillaris ) are partly incorrect. Owing to this Grandjean (1954c) created a genus Posthermannia that is in fact a synonym of Masthermannia , because Posthermannia nematophora (the type-species of the genus) appears to be identical with M. mammillaris . Two species of the genus are known: Masthermannia mammillaris (Berlese) (= Posthermannia nematophora Grandjean ), and Masthermannia hirsuta (Hartmann, 1949); the differences between them are given by Grandjean (1956a, p. 456).
