Remarks. Gordh (1979: 937) reported “an undetermined species” that ranged from Wisconsin to Montana, south to Nebraska, and in Florida and California. But in the original description of T. americanus, Gordh & Trjapitzin (1981) noted that the type series was based on only six specimens from Wisconsin and Utah, which leaves in doubt the identity of most of the other specimens Gordh mentioned in the earlier work. At the time of the original description males were unknown, but several male specimens from Los Angeles, Nevada and Plumas counties (UCDC, UCRC) have the same collecting data as female T. americanus, and are presumably conspecific.
