Carolinea 78

L amos : Remarkable Oribatida new to the fauna of Baden-Württemberg 131 of the humeral angle to some extent depends on the angle of tilt along the anterior-posterior axis, and also on the degree of notogastral distension of the examined specimen ( N orton , F ranklin & C rossley 2010). I regard the differences in the humeral angle between the Mannheim specimen and those of S ellnick (1929) and W eigmann (2006) as probably being due to either individual or geo- graphic variation within the species. Interestingly, the specimen from Mannheim shows a broken microsculpture pattern between the costulae with there being irregular ridges instead of complete alveoli. This conforms to the pattern, mentioned by N orton , F ranklin & C rossley (2010), shown by European populations of Scapheremaeus palustris as opposed to that of North American individuals. Microzetorchestes emeryi ( C oggi , 1898) Original combination: Zetorchestes emeryi C og - gi , 1898. Species identification based on C oggi (1898: 73, 83, + pl. 2, figs. 7-13) and W eigmann (2006: 222). Collected in the Dossenwald in Mannheim at an elevation of 110 m, from leaf litter and upper soil beneath a silver birch tree ( Betula pendu- la R oth ). Collection date 23.4.2005. Two adults were found. Comments: This is the first record of the species for Baden-Württemberg. Within Germany it has been noted to occur in Bavaria, North Rhine- Westphalia, Saxony and Thuringia ( W eigmann et al. 2015). Microzetorchestes emeryi displays a Palaearctic distribution and has, for example, been found in Portugal ( W eigmann 2013), South Tyrol in Italy ( S chatz 2018b), Finland ( N iemi 1995), Poland ( K limek & C hachaj 2018 ), Iran ( A krami 2015), Japan ( A oki 2005), China ( A oki et al. 1997) and the Russian Far East ( R yabinin et al. 2018). S chatz (2018b: 65) indicates that Microzetor- chestes emeryi is a xerophillic taxon. W eigmann (2013: 50) similarly states that M . emeryi occurs in the moss and soil of dry habitats. This cha- racterization applies well to the Mannheim colle- ction site in the Dossenwald ( L amos 2019), which lies in the Upper Rhine Rift Valley. Licnobelba latiflabellata ( P aoli , 1908) Original combination: Licneremaeus latiflabellatus P aoli , 1908. Species identification based on P aoli (1908: 87 + pl. 5, figs. 39, 55), G randjean (1931: 242) and P érez - Í ñigo (1994: 317, 1997: 71). Collected on the Königstuhl mountain in Heidel- berg, at an altitude of 430 m from crustose lichen on sandstone rock. Collection date 5.11.2007. One adult was found. Comments: Licnobelba latiflabellata was rede- scribed in detail by P érez - Í ñigo (1994), who con- cluded that Licnobelba alestensis G randjean , 1931 and L . montana M ihel č i č , 1957 are its junior synonyms. The species is known from numerous countries in the Western Palaearctic such as Italy ( P aoli 1908, S chatz 2018b), France ( G rand - jean 1931), Spain (P érez - Í ñigo 1997), Morocco ( G randjean 1934b), Poland ( O lszanowski , K ajski & N iedbala 1996), Belarus and Ukraine ( G ilyarov & K rivolutskij 1975), Turkey ( T oluk & A kin 2017) and Iran ( A krami 2015). It also was noted to oc- cur in the Volgograd Oblast in European Russia ( L ebedeva & P oltavskaya 2013), at Kolguyev Is- land in the Barents Sea in Arkhangelsk Oblast in the Russian Far North ( M elekhina 2020) and in at least one further site in the Russian Arctic ( L ebedeva & K rivolutsky 2003). Licnobelba latiflabellata seems to prefer relative- ly dry regions. It is listed as being a xerophile by W eigmann et al. (2015: 50), who also show the species as having been collected at only a single site in Germany. From the distribution map pro- vided by the authors it appears that they refer to the collection record SMNK 921 of the State Museum of Natural History Karlsruhe, later men- tioned by B eck , H orak & W oas (2018: 63), when discussing the discovery of the species at a lo- cation on the Kaiserstuhl at an elevation of 224 m. The collection of the specimen of Licnobelba latiflabellata in Heidelberg is therefore only the second time the species has been found in Ger- many. Parhypochthonius aphidinus B erlese , 1904 Species identification based on B erlese (1904: 25 + pl. 2, fig. 42), W illmann (1931: 98), B alogh & M ahunka (1983: 112, 284) and W eigmann (2006: 107). The species was discovered on two locations. It was collected in Neckarau in Mannheim at an ele- vation of 96 m from the organic litter layer under a pine tree ( Pinus L. sp.). Nine individuals including 6 adults were collected here on 23.06.2006. Fif- teen more individuals, of whom 10 were adults, were collected in the Luisenpark in Mannheim at an elevation of 100 m on 22.4.2009. There they were taken from the needle litter and uppermost topsoil under a giant sequoia ( Sequoiadendron giganteum ( L indl ) J. B uchholz ) .
