A description of this species, which is endemic to Neosho River, has
been prepared but not yet published by Dr. W. Ralph Taylor. I found the
Neosho madtom only at the middle station in 1958 and 1959, and at the
lower station in 1959, where the species was common in shallow water
having moderate current over clean gravel bottom. Specimens were most
effectively collected by digging into the gravel above the seine and
allowing the gravel to wash into the seine. In 1952, Cross (1954:311)
found this species in abundance in riffles at the confluence of the
South Fork and Cottonwood River, and at several other localities in the
Neosho mainstream (personal communication). The Neosho madtom is nearly
restricted to gravel riffles having moderate flow; therefore, it may be
drastically reduced by intermittency of flow. I found none in 1957 and
few in 1958. By 1959, the third summer of continuous flow, the Neosho
madtom was again common.
