Carolinea 78 (2020): 129-134, 0 Abb.; Karlsruhe, 29.01.2021 129 Some remarkable Oribatida (Acari) new to the fauna of Baden-Württemberg R aymond A. L amos Abstract Collection records for Baden-Württemberg in Germany are provided for seven rare oribatid mite species, five of which are so far unknown from this federal state. The species Camisia biverrucata (C. L. K och , 1840), Micro- zetorchestes emeryi ( C oggi , 1898), Neoliodes thele- proctus ( H ermann , 1804), Parhypochthonius aphidinus B erlese , 1904 and Scapheremaeus palustris (S ellnick , 1924) were discovered in sites in Mannheim. Camisia invenusta ( M ichael , 1888) and Licnobelba latiflabellata ( P aoli , 1908) originate from the Königstuhl mountain near Heidelberg. Camisia invenusta is recorded for the first time in Germany. Kurzfassung Einige bemerkenswerte Oribatida (Acari) neu für die Fauna Baden-Württembergs Sieben seltene Oribatidenarten wurden in Baden- Württemberg gesammelt und werden hier vorgestellt. Fünf Arten sind neu für Baden-Württemberg. Die Arten Camisia biverrucata (C. L. K och , 1840), Microzetor- chestes emeryi ( C oggi , 1898), Neoliodes theleproctus ( H ermann , 1804), Parhypochthonius aphidinus B erlese , 1904 und Scapheremaeus palustris ( S ellnick , 1924) wurden in Mannheim entdeckt. Camisia invenusta ( M i - chael , 1888) und Licnobelba latiflabellata ( P aoli , 1908) stammen vom Berg Königstuhl bei Heidelberg. Camisia invenusta wird zum ersten Mal für Deutschland nach- gewiesen. Author R aymond A. L amos , Rosenstr. 21, 68199 Mannheim; E-mail: cicindela127@protonmail.com Introduction A comprehensive monograph on the oribatid fau- na of South-West Germany was recently provi- ded by B eck , H orak and W oas (2018). In the fol- lowing I will present distribution records for some rarely collected Oribatida not listed by these authors and which, to the best of my knowledge, are up to now unknown from Baden-Württem- berg. Additionally, new records for Licnobelba latiflabellata ( P aoli , 1908) and Parhypochthonius aphidinus B erlese , 1904, each so far known from South-West Germany on the basis of only a sin- gle occurrence, are supplied. Methods The mites were extracted from the collected ma- terial either by hand employing a fine brush, or by using a Berlese funnel. They were fixed in 70 % ethanol, macerated in lactic acid and examined under a light microscope. Specimens were stored in microvials in 70 % ethanol. All Oribatida were collected by the author. Altitude values in the text are given in metres above mean sea level. One or more representatives of each species were depo- sited as voucher specimens in the oribatid colle- ction of the Zoology section of the State Museum of Natural History Karlsruhe, in Germany. Results and Discussion Camisia biverrucata (C. L. K och , 1840) Original combination: Nothrus biverrucatus C. L. K och , 1840. Species identification based on K och ( 1840: sec- tion 15), C olloff ( 1993: 1391, 1404), O lszanow - ski (1996: 25, 40) and W eigmann (2006: 152). Collected in the Dossenwald in Mannheim at an elevation of 112 m from fruticose lichen ( Clado- nia H ill ex P. B rowne ), growing under Scots pine ( Pinus sylvestris L .). Collection date 11.10.2009. Nine adults were found. Comments: This is the first record of the spe- cies for Baden-Württemberg. Camisia biverru- cata is noted to occur in Saxony, Thuringia and Schleswig-Holstein by W eigmann et al. (2015), who consider it a rare species. It is also known from Austria, Switzerland and the Italian Alps and shows a Holarctic distribution ( S chatz 2020). The name Camisia biverrucata is dated to 1839 by virtually all authors mentioning it, including C olloff ( 1993), O lszanowski (1996) and W eig - mann (2006). I here follow M ichael (1898: 71) and W illmann (1931: 109) in dating the species to 1840 instead. An original print of K och ´s Vol. 29 of “Deutschlands Crustaceen, Myriapoden und Arachniden” in the Bavarian State Library, in which Camisia biverrucata is described, is dated to 1840. The descriptions of three other Croto- nioidea T horell , 1876, namely Camisia biurus (C. L. K och , 1840), Nothrus palustris C. L. K och ,
