Fidia atra

Fidia atra is a species of leaf beetle in the family Chrysomelidae.

In nature, the body is covered with a white powdery excrescence; when rubbed, it has a shining black colour.

The distal ends of the tibiae, the tarsi, the basal three segments of the antennae, and the labrum are fulvous in colour.

[2] The species was first described by Victor Motschulsky in 1861 from specimens that had been rubbed, therefore lacking the white powder covering the beetle's black body, giving it the name "atra" (from ater, the Latin word for black).

[5] The species was later described a third time by Léon Fairmaire in 1889 under the name Talmonus farinosus, which was synonymised by Jacoby the following year.
