Tampichthys is a genus of cyprinid fish endemic to east–central Mexico.[1] They are entirely restricted to the Pánuco River basin, except T. ipni which also occurs in some other Mexican rivers that drain into the Gulf of Mexico.[1]
These are small fish, generally no more than long, and overall brownish-silvery with a distinct dark horizontal line from the head to the tail base.[1]
Tampichthys was formerly considered a part of Dionda instead of a separate genus.[1] There are six described species in Tampichthys, but undescribed species are known.[1]
