Pachyschelus female
This specimen of Pachyschelus is a female. The sexes are easy to tell apart. Females have a small comb of teeth at the apex of the last abdominal sternite which in most North American species is divided medially by a notch, which can easily be seen in the ventral view of this specimen. Males have a simple last sternite without teeth.

Male or female?
Can anyone tell if the adult is male or female?
