The new species according to morphological characters belongs to the subgenus Nathrenus Casey, 1900 , and from other Canarian species differs by the following characters¡

- antennae composed of 9 antennomeres…………………..…………………… A. ( Anthrenops ) coloratus Reitter, 1881

- antennae composed of 10 antennomeres……………………………………… A. ( Anthrenodes ) minor Wollaston, 1865

- antennae composed of 11 antennomeres………………….…………………… A. ( Nathrenus )

- antennal club with three short, narrow, black antennomeres, body oval………………………………………………………………… A. verbasci (Linnaeus, 1767)

- antennal club with one short and two very large, broad, dark-brown antennomeres…………………………………..………… A. canariensis sp. nov.
