Cerylonidae Billberg, 1820

Cerylon ferrugineum (1.7-2.1 mm) ( Fig. 6A ) and C. histeroides (1.8-2.3 mm) ( Fig. 6B ) are two common European species, occurring throughout the hole province of Limburg (Annex), associated with both coniferous and deciduous trees. In the debris of ant nests, C. histeroides can be found in a concentration of several tens of specimens, as shown when sifting wood dust from a birch in the Kolmontbos in Tongeren ( Table 3). Next to the two species presented in Table 3, a third species of the genus Cerylon Latreille, 1802 has been found in Limburg, Cerylon fagi Brisout, 1867 (2.1-2.6mm), but with only six specimens captured in just four 1 x 1 km grids it has the most restricted distribution. For this species no association with ants was observed.
