New Corydoradinae Catfish's from Mato Grosso

As widely known, the number of putative new species of Corydoradinae arriving at local fish shops is clearly higher than the number of new species being discovered in scientific expeditions. One of the reasons is due to the lack of financial support for scientific expeditions in general, especially in particular cases where the specific capture of a single species is sought, for example. In Mato Grosso State, Central Brazil, it is possible to find tributaries of the upper rio Paraguay basin and also from the rio Amazonas basin, such as the upper portions of the rivers Araguaia, Madeira, Tapajós and Xingu. Dozens of possibly undescribed species from these basins are currently known in the hobby. Regarding the coded species within Mato Grosso State, some of them recently caught our attention, such as: Corydoras sp. CW68, CW152 and especially CW162. Additionally, an undescribed species of Aspidoras is also in our radar, since despite being clearly new, the currently available material is in poor condition and no photos in life and from its habitat are available. Both Corydoras sp. CW68 and CW152 are part of ongoing works, which are expected to be published in 2024.
