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 insignis (Berlese, 1904) Lohmannia insignis Berlese , 1904b, p. 23, pl. 2 fig. 41; Carpenter, 1905, p. 294, pls. 25, 26A; 1905a, p. 249, pl. 7; Lombardini, 1936, p. 47. The type of the species is no more present in the Berlese Collection. The type-specimens were sent to Berlese from Ireland by Halbert; consequently cotypes may still exist somewhere as part of the Halbert Collection, although until now they have not been discovered. The species was redescribed by Carpenter, who collected his specimens also in Ireland. Hewitt, who in 1908 described Lohmannia insignis var. dissimilis (now Perlohmannia dissimilis ), has compared his " variety " with the type of insignis Berlese , so that it was still present at that date. In the Michael Collection, property of the British Museum (Natural History), there is a slide of " Lohmannia insignis ", which was apparently sent to Michael by Berlese. A description of this material will be interesting; Mr. D. Macfarlane (in litt.) kindly informed me that the prodorsal hairs are arranged as in dissimilis ; the identity is therefore uncertain.
