Agnetina flavescens (Walsh) .

This species has a distribution similar to A. capitata , but is generally more southern in distribution or found in streams without significant groundwater input. It has been extirpated from Illinois ( DeWalt et al. 2005). All INHS specimens were re-examined and from these records we know that this species often co-occurred with A. capitata in the Salt Fork of the Vermilion River in eastern Illinois and in the Kankakee and Rock Rivers of northern Illinois. Grubbs (2004) lists the species from three widely separated counties in Indiana. The species once inhabited larger rivers throughout the state, but is now relegated to smaller, permanent streams in unglaciated southern Indiana. This pattern of range loss is similar to that exhibited by A. frisoni .
