Differences in spider assemblages between the two tree species are discussed with particular emphasis on the dominant species and taxa. For the rare species Theridion boesenbergi Strand, 1904 remarks on their occurrence in Bavaria, Germany and Europe are given. For Cinetata gradata (Simon, 1881) we present an update to the entire known distribution including a new map. For both species new records are specified and discussed concerning habitat preference, phenology and distribution. Both species seem to be obligate tree colonisers, C. gradata primarily in the canopy stratum. Adults of C. gradata are to be found during all months of the year; T. boesenbergi exhibits an abundance peak in June, males are known to occur from May to August and females the whole year round. The distribution of both species is restricted to Europe, excluding the northern and western parts (Arctic and Atlantic climate) and the Mediterranean zone.
