North America: upper Rio Grande (above El Paso, Texas), Texas and New Mexico and in the Pecos River, New Mexico, USA. Has disappeared over much of its former range, apparently due to reduced water levels in the Rio Grande system (Ref. 3881).
北美洲: 發現於大河上游 (上方 El Paso 德克薩斯) ，德克薩斯與新墨西哥州了與在新墨西哥的佩科斯河中。 在許多的它的從前的分佈區域已經消失, 顯然地由於在 Rio Grande 系統水位下降。

Inhabits the main channels of the Rio Grande and Pecos River usually over sand or gravel. With two subspecies: N. s. simus known from Rio Grande above El Paso, Texas, but now possibly extinct; N. s. pecosensis known only in the Pecos River, New Mexico, recognized as a threatened subspecies (Ref. 5723).
栖息于大河的主水道，而且佩科斯河通常在沙子或砾石上面。 有两个亚种: N. s。 simus 已知来自在 El Paso ，德克萨斯上面的大河了, 但是现在可能灭绝; N. s。 知道的 pecosensis 只在被鉴定为一个受威胁的亚种的新墨西哥的佩科斯河中。 (参考文献 5723)
