Von Juan Miguel Artigas Azas

A new species of livebearer fish: Poeciliopsis jackschultzi from the state of Sonora in Mexico has been recently described by Kevin Conway, Mariana Mateos and Robert C. Vrijenhoek in the journal Zookeys. The new species is currently only known from four sites in the Río Concepción, where it is sympatric with P. occidentalis. It is mainly diagnosed by the absence of a black spot at base of the frontal part of the dorsal fin on males, unique in the Leptorhaphis species group of Poeciliosis. The specific name is given to honor Jack Schultz, a pioneer of studies on hybridization and all-female reproduction in Poeciliopsis.
