Morphometric measurements On Coura amboinensis subspecies

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

C.a. amboinensis
C.a. couro
C.a. kamarona
C.a lineata

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.
