American scientists have described a new species of livebearing fish endemic to Lake Catemaco in Mexico.

The new species is named Heterandria tuxtlaensis, after its type locality (the Tuxtla Mountains in Mexico), by John McEachran and Thomas DeWitt in a recent issue of the journal Zootaxa.

Heterandria tuxtlaensis most closely resembles H. bimaculata, but in possesses shorter dorsal and caudal fins, a shorter dorsal fin base composed of fewer fin rays, a shallower body, and a relatively small basicaudal spot restricted to the area above the midlateral line.

Mexico (Cyprinodontiformes: Poeciliidae). Zootaxa 1824, pp. 45"54.
