title: Redescription of Coronoquadroppia monstruosa (Hammer, 1979) (Acari, Oribatida, Quadroppiidae) from Java and variability of the species in Europe.
abstract: A main goal of this study was the comparison of type material of Coronoquadroppia monstruosa (Hammer, 1979) from Java with European populations which were supposed by authors to be conspecific. The species identity of most respective European findings with a type specimen can be confirmed. Yet within some populations from Germany, Austria and northern Italy, specimens with morphological variations are present, resembling partly C. gumista (Gordeeva et Tarba, 1990) from the Caucasus in regard of a transversal band in the rostral structure. This and other described modifications are supposed to be individual variability within the species C. monstruosa. A detailed morphological analysis is presented, resulting in the division of the Quadroppia complex into the genera Quadroppia and Coronoquadroppia as first proposed by Ohkubo (1995).
