What's subspecies?

Snakesitter · 02-12-2007, 06:35 AM

Hi there.

I'm looking after a snake for a friend. Now I know he's a marcianus, but how do I know which marcianus he is?

Wikipedia says there's three subspecies of marcianus: marcianus, praeocularis and bovalli. I've not been able to find any information or pictures on what the differences are. Perhaps somebody here can help.

Thanks

Karl

preoculis and bovalli are mexican subspecies and not available in the pet trade. He have a marcianus marcianus, the common checkered garter, nice snakes too!!!

Yep, pretty much the only ones out there are T.m.marcianus.

Cool enough. Does anybody know what the differences are between the three?

The two other subspecies are not Mexican, but live even more southwards...

Thamnophis marcianus bovalli - from southwest Nicaragua up to northern Costa Rica.
Thamnophis marcianus marcianus - from southwest Kansas to the west up to southeastern California and southwards, viavia the north and east of Mexico, up to northern-Veracruz. In Tehuantepec (Oaxaca, Mexico) lives an isolated population.
Thamnophis marcianus praeocularis - from the Yucatan-peninsula, via Belize and northeastern Guatemala up to western Honduras.

I do not know the physical differences.
