Tomocerus minor


The genus Tomocerus is recognisable for having a very long 3rd antennal segment (ant.3). 
Tomocerus minor can be up to 4.5 mm long with antennae that are shorter than the body. This species has a characteristic uniform silvery-bluish iridescence. Its close relative Pogonognathellus flavescens with which it can be confused can be distinguished as follows: in T. minor the long 3rd antennal segment is sub-cylindrical but in P. flavescens it is tapering apically also the length of the short 4th antennal segment in T. minor it is about as long as the sum of the 1st and 2nd antennal segment, whereas in P. flavescens it is distinctly shorter.
The most characteristic feature of T. minor can only be determined microscopically - the presence of tridentate spines on the dens (upper part of the furcula). 


Damp and shady places, under stones and logs or in leaf litter and moss.
