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 Trhypochthoniellus longisetus (Berlese, 1904) Trhypochthonius longisetus Berlese , 1904b, p. 27, pl. 2 fig. 44. I have placed the present species in the genus Trhypochthoniellus because the notogastral hairs are described as long and smooth, and the structure of the notogaster as shining. The type is, however, no more present in the Berlese Collection. Because the species was collected in hothouses in Florence, it was perhaps introduced from a tropical country. The identity of T. longisetus remains therefore uncertain.
