all Matus bicarinatus
I'll have to try and find some Matus from a different wetland to get the other species.

Dissected 2 males..
that you sent me..the genitalia confirms the ID..the other 2 were females that I IDed based on other characters not visible in photos (underside microsculpture). I plan to take microscope pics of dissected genitalia and other diagnostic characters to accompany the photovouchers of the beetles you sent me..that will hopefully be later in August or early September when I plan to take some time off work.

2 species in your area
distinguishing characters not visible here. Hopefully you have saved it and the other dytiscids for photovouchering.

I saved the whole bunch for you
I have ventral shots of these 4 Matus and can post them if that helps.
