Medford, (~15 miles east of Philadelphia, PA) Burlington County, New Jersey, USA July 11, 2006 Size: ~2.3mm
Bidessus is stated to have pro and mesotarsi with 5 segments, where most other related Dytiscidae appear to have 4 (actually have 5 with one greatly reduced). If you look closely, I hope you can see 5 in this photo (the fifth is much longer than the others, slightly curved, and can appear to look like claws).
