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 Perlohmannia Berlese, 1916 Perlohmannia Berlese, 1916a, p. 176. The genus Perlohmannia , which was created by Berlese in 1916, has Lohmannia insignis Berlese (1904) as type; Berlese did not give a generic diagnosis. Two representatives only have been described 1). The second species, P. dissimilis (Hewitt, 1908), was thoroughly studied by Grandjean (1958); it was also mentioned in the Catalogue by Lombardini (1936, p. 47). 1) Perlohmannia eximia is a nomen nudum mentioned by Berlese (1916a, p. 176). Apparently Berlese was not aware of the fact that the diagnosis had never been published by him. A slide bearing this name is present in the Collection; it is mentioned by Lombardini, 1936, p. 47.
