|Scientific Name:||Etheostoma histrio|
|Species Authority:||Jordan & Gilbert, 1887|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Smith, K. & Darwall, W.R.T.|
|Facilitator/Compiler(s):||Hammerson, G.A. & Ormes, M.|
Listed as Least Concern because extent of occurrence, number of subpopulations, and population size are relatively large, and because the species probably is not declining fast enough to qualify for any of the threatened categories.
|Range Description:||This species is scattered throughout lower Mississippi River tributaries west (in the Red and Arkansas river drainages to eastern Oklahoma and eastern Texas, and north to southeastern Missouri, southern Illinois, and western Kentucky; it also occurs in isolated areas in the Wabash River drainage, Illinois and Indiana, and Green River system, Kentucky; this darter also occurs in Gulf Coast drainages from Escambia River, Alabama and Florida, to Neches River, Texas (Page and Burr 2011).|

|Population:||This species is represented by a large number of occurrences (subpopulations).
Total adult population size is unknown but presumably exceeds 10,000. This species is widely distributed but generally uncommon (Page and Burr 2011). Recently it has been recognized as more common than previously thought.
Trend over the past three generations is uncertain but probably relatively stable or slowly declining.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Habitat includes sand and gravel runs of small to medium rivers (Page and Burr 2011). Above the Fall Line this darter occurs most often in riffles with coarse gravel substrate; in lowland streams, it often occurs over sand among brush and detritus where logjams have created strong mid-stream currents.|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Threats include habitat destruction or modification such as river channelization and pollution.|
|Conservation Actions:||Research is needed on the ecology of the species, especially habitat requirements. Better information is needed on current distribution and abundance. Species would benefit from increased protection of occupied waters.|
