Globally, there are 71 species of Taxonus distributed throughout the palaearctic, nearctic and the orient. They are represented in Britain by one species.
The genus Taxonus is charcterised in the subfamily Allantinae by the following characteristics. The forewing has four cubital cells with cells 1R1 and 1RS present as discrete cells and vein 1m-cu is longer than vein cu-a. In common with other genera in the Allantinae the body is slender with the abdomen longer than the thorax and head combined.
