1] The Central Vietnamese three-striped box turtle (Cuora cyclornata cyclornata)

This subspecies can easily be distinguished from Cuora trifasciata and C.cyclornata meieri by its orange chin, its round carapace appearance, the Cuora mccordi/ Boletus like plastral pattern i.e. a generally large black blotch extending from the Anal scutes to the pectorals (in C.trifasciata & C.c.meieri extending to the gulars) with a thin black vertical black stripe along the pectoral-humeral suture only and two separated black longitudinal bars on the gular scutes. This subspecies can reach a carapace length of up to 25cm, males are smaller than females (as usual in Cuora species).

 
2] The northern Vietnamese or Meiers three-striped box turtle (Cuora cyclornata meieri) 

This subspecies can be differentiated from the C.cyclornata cyclornata and C.trifasciata by the oval shell shape, a white to pinkish chin, rounded humeral-pectoral sutures and a filled Boletus plastral pattern. This subspecies can reach a carapace length of up to 30cm, males are smaller than females (as usual in Cuora species)

The Vietnamese three-striped box turtle (Cuora cyclornata) ,  It can be distinguished from Cuora trifasciata by its larger size and generally more oval or rounder shell, which is usually also flatter, a white, pink or orange chin and head coloration with an orange-brownish-olive dorsal head pattern and less black pigments.

1] The Southern Vietnamese Box turtle (Cuora picturata)  This species has the highest domed carapace of all Cuora species, the shape resembling a Conquistator helmet. While the head coloration of Cuora galbinifrons subspecies is highly variable even in different populations, this is not the case with C.picturata, where the head is always yellow with a fine greyish reticulation.



Cuora picturata (southern Annam, south Vietnam);


 Cuora galbinifrons galbinifrons (north Vietnam),


Cuora galbinifrons galbinifrons (Hainan, China);


Cuora (galbinifrons) bourreti (Annam, central Vietnam),


Cuora (galbinifrons) bourreti (Laos);

1] The central Vietnamese Flowerback box turtle (Cuora galbinifrons bourreti) The most notable difference to the Cuora galbinifrons galbinifrond is the distinct plastral pattern, where only smaller black blotches (sometimes none at all) occur.
