Entomologia e Acarologia; Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo; Piraci- caba, SP, Brazil Acarology has been a very active area of research in South Africa for many years, especially with reference to taxonomy. For this reason, mites of agricultural importance are well known in that country compared to many other countries. Edward A. Ueckermann is a South African acarologist who has contributed enormously to knowledge about the mites of his country, as well as from many other countries around the world. Eddie, as he is called by his friends, is an admirable man, both for his enviable professional qualities and for his tremendous personality. The authors of this brief biography are glad to have had the opportunity to collaborate with Eddie as authors of several publications51, 52, 58, 70, 75, 80, 87, 92, 95, 101,103, 104, 107, 112, 114, 117, 121, 143, 151, 160, 189, 203, 207, 211, and to interact with him in many other ways. Eddie was born in Postmasburg, Northern Cape Province, South Africa, on 19 January 1951. He completed secondary school in his hometown and after a year of compulsory military training, Eddie enrolled at North- West University, Potchefstroom, in 1971 to study a B.Sc. -

Until now, the data on oribatid species have not been published. This paper presents a list of oribatid species collected during 21 years of ongoing research in three pine stands of different age. The faunistic records refer to 84 species (including 17 species new to the fauna of Latvia), 1 subspecies, 1 form, 5 morphospecies and 18 unidentified taxa. The most dominant and most frequent oribatid species are Oppiella (Oppiella) nova, Tectocepheus velatus velatus and Suctobelbella falcata. Key words: species list, fauna, stand-age, LTER, Mazsalaca INTRODUCTION Most studies of Oribatida or the so-called armoured mites (Subías 2004) have been relatively short term and/or from different ecosystems simultaneously and do not show long- term changes (Winter et al. -

Bolzano, Italy) – Investigations in the frame of the research week 2016 Abstract Oribatid mites were investigated in the frame of the "Long-Term Socio-economic and Ecosystem Research" in the Matsch Valley / Val di Mazia (municipality of Mals / Malles Venosta), Vinschgau Valley, South Tyol. Soil and litter samples were taken from characteristic microhabitats in the following sites: dry grasslands and pastures at 1000, 1500, 2000 m a.s.l., fertilized meadows (1500 m a.s.l.), larch forest pastures (1500 m a.s.l.) and montane pine forest (about 2000 m a.s.l.), 3 replicate sites each. A total of 119 oribatid species belonging to 41 families were encountered. The species Gymnodamaeus meyeri BAYARTOGTOKH & SCHATZ, 2009 is a new record for Italy, Eobrachychthonius latior (BERLESE, 1910) Feiderzetes latus (SCHWEIZER, 1956), Licnodamaeus costula GRANDJEAN, 1931, Paratritia baloghi MORITZ, 1966, Pergalumna dorsalis (C.L. KOCH, 1841), Phauloppia rauschenensis (SELLNICK, 1908) are new records for South Tyrol. The majority of the species have a wide general distribution – palaearctic, holarctic, or semi/cosmopolitan, others show a restricted distribution to Central Europe and the Alps. A remarkable number of species can be classified as „southern species“ (distribution center in southern Europe or in the southern Palaearctic region).
