LEEWAY CORUCIA RESEARCH CENTER (LCRC)
The following I have provided in an effort to help those working with the species: Coria amboinensis.
Note: This is not a fully researched scientific Paper – but a guide.
There are 4 species documented for Coria Amboinensis
The Ultimate Turtle page www.turtlepuddle.org/coura/amboinensis.html
Filea, eduard 1997. Coria amboinensis la tort igucaju (the South eastern asian turtle and it’s subspecies) Reptilia 3/(13) :43-47.
C.a. Lineata > easily distinguishable by light stripe along keel of carapace.
C.a. kamarona > more domed carapace and smaller, more elongated spotting of black pigments of plastron.
C.a. amboinensis >
C.a. couro > Darker more oval black spots on plastron, flatter carapace >it is the lack of complete differentiation of the latter two subspecies that make this an observational topic only.
MEASUREMENTS (Taken at the LCRC):
Coura amboinensis kamarona
Average ratio of carapace length/ height: 2.82
Average ratio dimensions of plastron spots: 2.14 (small and elongated)
Coura amboinensis amboinensis?
Average ratio of carapace length / height: 3.08
Average ratio dimensions of plastron spots: 1.21 (almost circular)
On the LCRC carapace lengths – these were, of course straight length measurements as would be standard with carapace measurements.
I hope this will help in proper subspecies identification.
