The maculations seem to fit mainensis best but seem possible for interrupta. The pattern on legs and antennae, however, seem fairly typical of interrupta (which may be more likely based on range) and not consistent with mainensis.. However, of knabi, is very close in both maculation pattern and geographic location.
