Botero & Santos-Silva (2022) ont montré que l'espèce cité par Morvan & Roguet (2013) n'était pas leuconotum mais une nouvelle espèce :

Anobrium bicolor new species is similar to A. leuconotum Galileo and Martins, 2002, and has been confused with it. However, they differ as follows: elytra slightly shorter than three times prothoracic length; pubescence on vertex and elytra distinctly denser; lateral tubercles of the prothorax conical and not apically directed backward; and mesoventral process with distinct central tubercle. In A. leuconotum, the elytra are proportionally longer, slightly longer than 3.5 times prothoracic length, the pubescence on the vertex and
elytra are noticeably sparser, the lateral tubercles of the prothorax are spiniform and apically directed backward, and the mesoventral process has no tubercle. Anobrium bicolor is also similar to A. luridum (Breuning, 1940), but differs by the elytral pubescence distinctly denser, and the elytra proportionally shorter (about 3.5 times prothoracic length in A. luridum).
