The spottail chub (Algansea tincella) is a species of freshwater fish in the family Cyprinidae, endemic to the Lerma–Chapala basin and upper Santa Maria (Tampoán) system in west-central Mexico.

[2][3][4] Populations of the Ameca River basin were formerly included in this species, but are now recognized as A.

[3] There are some minor local variations in the appearance of A. tincella, but they all have a dark spot at the base of the tail.

The species generally is about 5–11.5 cm (2.0–4.5 in) in standard length.
