Their range is centered in the Rio Grande basin, but they also occur in associated systems, including Nazas–Aguanaval of north–central Mexico, and Nueces, San Antonio and Colorado of Texas.[2] These are small fish, no more than {{cvt|9|cm|in}} long, and overall brownish-silvery with a distinct dark horizontal line from the head to the tail base.[1] They are believed to feed primarily on algae. SpeciesThere are currently six species in this genus.[1] Additionally, the species now placed in Tampichthys were formerly included in Dionda instead.[2]
