A Catalogue of Oribatida Types of the “Balogh Collection” in the Hungarian Natural History Museum (Arachnida, Acariformes)

Academician János Balogh was one of the most outstanding acarologists of his time. During his collecting expeditions around the world, he amassed an internationally significant collection of mites and described more than 1,000 species of oribatid mites. This outstanding collection is now housed in the Hungarian Museum of Natural History. In this article, we summarise the results of the revision of his collection and adapt the nomenclature of the species to the current taxonomy. A total of 1142 Oribatida species names are reported that can be attributed to the work of János Balogh, Judith Csiszár or Péter Balogh. Of these, we found the holotypes of 674 species in the collection, and the holotypes of 289 species that should be in the collection according to the literature appear to be missing. In addition, we also report names described by J. Balogh and P. Balogh in 2002 that do not meet the current ICZN requirements and should be considered nomina nuda, as follows: Acroppia papuana J. Balogh & P. Balogh, 2002; Cavernocepheus obliquus P. Balogh, 2002; Cavernocepheus undulatus P. Balogh, 2002; Dimidiogalumna walworki J. Balogh & P. Balogh, 2002; Dolicheremaeus berlesei J. Balogh & P. Balogh, 2002; Flagroscutobelba simillima J. Balogh & P. Balogh, 2002; Galumna engelbrechti J. Balogh & P. Balogh, 2002; Malaconothrus valeriae J. Balogh & P. Balogh, 2002; Paulinacarus sarkari J. Balogh & P. Balogh, 2002; Pedrocortezella pletzenae J. Balogh & P. Balogh, 2002; Pulchroppia mahunkarum J. Balogh & P. Balogh, 2002; Rhysotritia niedbalai J. Balogh & P. Balogh, 2002; Scapheremaeus hammerae J. Balogh & P. Balogh, 2002; Scutobelbella permixta J. Balogh & P. Balogh, 2002; Trimalaconothrus multipilosus J. Balogh & P. Balogh, 2002. In addition, three other replacement names have been synonymised because the secondary homonymy no longer exists, namely Megascheloribates pajaki J. Balogh & P. Balogh, 2002 (= Scheloribates (Scheloribates) microsetosus (Lee & Pajak, 1990)); Pedrocortezella pletzenae J. Balogh & P. Balogh, 2002 (= Pheroliodes africaus (Balogh, 1966)) and Unguizetes hammeri J. Balogh & P. Balogh, 2002 (= Chamobates (Chamobates) javensis (Hammer, 1979)).
