The type species for this genus is Aspidoras rochai. The name Aspidoras is derived from the Greek aspis (shield) and dora (skin).

Aspidoras Aspidoras Wikipedia

Aspidoras is easily distinguished from the other genera of the subfamily Corydoradinae by the presence of a supraoccipital fontanel; this character is an autapomorphy for the genus. Many of the species of Aspidoras are similar and often hard to distinguish. Without specimens, it is often very difficult to positively identify a species from photographs alone. They are all small species. A. taurus is exceptional in that it just surpasses 5 cm in length.

The monophyly of the genus has been demonstrated.

A. albater, A. eurycephalus and A. gabrieli from the Tocantins River system. A. brunneus, A. marianae and A. microgalaeus from the Xingu River system. A. belenos, A. pauciradiatus and A. velites from Araguaia River system. A. rochai from rivers around Fortaleza. A. raimundi from the Parnaíba River. A. carvalhoi from rivers around Guaramiranga, Ceará State. A. maculosus from the Itapicuru River. A. menezesi from the Jaguaribe River. A. spilotus from the Acaráu River. A. poecilus from the Xingu River, Araguaia River, and Tocantins River systems. A. psammatides from the Paraguaçu River. A. virgulatus from the coastal rivers in Espírito Santo.

A. taurus is known from the upper Itiquira River and upper Taquari River, both tributaries of the Paraguay River, Mato Grosso State, Brazil.

    In the aquarium

    Aspidoras Aspidoras Wikipedia

    Aspidoras do fairly well in aquaria under similar conditions as for most Corydoras species. The water conditions that seem best are a pH of 6.8 to 7.0 and a temperature of about 22 °C to 26 °C. The species that is most likely to be found in an aquarium is the sixray corydoras, Aspidoras pauciradiatus.
