This species is claret-brown in colour and under a lens it is seen to be marbled with white, indeed in appearance it is much like Trichoniscus pusillus though twice the size. There are important differences between the two species as regards the number of joints to the flagellum. These vary from five to seven in Trichoniscus vividus while in the other, as already pointed out, there are not more than four.
The body is practically speaking smooth for it bears only very small tubercles, widely separated. In Trichoniscus vividus the antennæ lack the bristles which characterise those of the other species in the genus. The species under consideration was discovered by Dr. Kinahan in March, 1858, at Portlaw, Co. Waterford and is active even amongst the snow.
