 minutus Carlson. Northwestern Va., s. Mich. Ecology: In Mich, seven specimens were collected 

 with sweep nets on an upland field (abandoned farm site) with gravelly soil and a

 pygmaeus (Cresson). N. S. w. to s. Alaska, s. to S. C, Ala., n.e. Kans., Colo., and Calif.; Eurasia. 

 Host: Paratobesia vitea)ia (Clem.), Acleris variana (Fern.). This is T. pallipes Holmgren 

 (1873) in the sense of 20th Century European authors preceding Aeschlimann (1973). 

 Overlooking the priority of pygmaeus, Townes and Townes (1959) erroneously 

 suppressed it as a synonym of pallipes. Aeschlimann (1973) has shown that the pallipes 

 "lectotype" selected by Aubert (1968) (.=pygmaeus) is invalid, and selected a valid 

 lectotype which is not conspecific with pygmaeus.
