Poeciliopsis jackschultzi sp. 11 月，基于来自墨西哥索诺拉州康塞普西翁河（也称为马格达莱纳河）的七个样本（17.9-26.7 毫米 SL）进行描述。该新物种属于 Leptorhaphis 物种组，可以通过骨骼和颜色特征与该组的其他成员区分开来。这个新物种与P. occidentalis同域，这是一种杂交遗传的全雌性生物型P. monacha-occidentalis，以及P. monacha-occidentalis雌性和P. jackschultzi雄性的杂交种。 P. jackschultzi 的分布受到高度限制，其主要栖息地是泉水供给的沼泽溪流和水池，在沙漠环境中，随着人类对水需求的增加，很容易遭受损失和退化。
Poeciliopsis jackschultzi sp. nov., is described based on seven specimens (17.9-26.7 mm SL) from the Rio Concepcion (also known as Rio Magdalena), Sonora, Mexico. The new species belongs to the Leptorhaphis species group and can be distinguished from other members of this group by features of the skeleton and colouration. The new species is sympatric with P. occidentalis, a hybridogenetic all-female biotype P. monacha-occidentalis, and hybrids between P. monacha-occidentalis females and P. jackschultzi males. The distribution of P. jackschultzi is highly restricted, and the main habitat, spring-fed marshy streams and pools, is susceptible to loss and degradation in a desert environment with increasing human water demand.
