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 Hermannia gibba (C. L. Koch, 1839) Nothrus gibbus C. L. Koch , 1839, fasc. 29 (4). Angelia piceus , Berlese, 1885c, pp. 9, 10. Nothrus piceus , Berlese, 1886a, fasc. 33 (6). Hermannia picea , Berlese, 1896b, p. 31; 1913a, p. 157, prep. II-13. Berlese contributed the species to the genera Angelia , Nothrus , and Hermannia successively. In the " Acari Myriapoda et Scorpiones " (1886a) he mentioned Nothrus convexus C. L. Koch and Hermannia crassipes Nicolet as Synonyms. In fact Nothrus piceus C. L. Koch , and Nothrus convexus C. L. Koch are different species, whilst Berlese overlooked that the species described by him is identical with Nothrus gibbus C. L. Koch . H. gibba is present in the Acarotheca italica, but appears to be absent from the Berlese Collection. I remark that little has been published on the morphology of this common species, although it appears highly interesting; I refer to my future monograph.
