I have two forms of Kinosternon scorpioides scorpioides. The southern form used to be considered as the subspecies Kinosternon scorpioides seriei but I believe it is now thought to be part of K. s. scorpioides. They look different to me and with the way names are continually changing, I have not mixed them together. Below are photos of males of each form.
Carapace of northern form
Carapace of southern form
Plastron of northern form
Plastron of southern form
Head of (unwilling) northern form
Head of southern form
Size comparison between two adult males of both forms (northern form on right, southern on left)
I'll take comparison photos of females of each form and post them later.
