Etheostoma (Etheostoma) histrio Jordan and Gilbert 1887

Distribution

Patoka River NWR: 78

Muscatatuck NWR: 6, 14

The harlequin darter was thought to be extripated from Indiana until its rediscovery within the White River Drainage in 1991 ( Simon and Kiley 1993). It has since been collected from other subwatersheds within the White River and also from the Patoka River ( Simon et al. 1995). The harlequin darter was collected from Vernon Fork Muscatatuck River at two sites, while the rediscovery of it was documented in the mainstem Patoka River upstream to the mouth of South Fork Patoka River. These records constitute the furthest removed records for the harlequin darter from the main stem of either branch of the White River (Table 1).

Ecology

Two Harlequin darter individuals were collected over gravel/sand riffles with swift current.
