 DIAGNOSIS. The male differs from all other Thrinchostoma in that the antennae have only 12 segments. The form of the last antennal segment in this species is more or less straight or flattened depending of the specimens. T. telekii falls within the variations of T. emini.   
The female differs from other species by the scutum being completely covered with a dense beige tomentum.
