Anabaraspis is a genus of redlichiid trilobite, A. splendens occurs in the uppermost Lower Cambrian and lowest Middle Cambrian of Russia (Toyonian and lower Amgan, A. splendens and Oryctocara Zones, northwestern and southeastern Yakutia). In Anabaraspis, there is an extended area in front of the glabella which is not differentiated in a border and a preglabellar field. It is a unique character in the family Paradoxididae.

The frontal lobe of the central raised area (or glabella) of the headshield (or cephalon) is slightly pointed rather than rounded or truncate, a character shared with Plutonides, though, in Plutonides, it hangs over the short anterior border.[2]
