I have lots of mappas in my collection. I've been researching on the net but can't find answers. I'm not even sure how to group them because some have pink base, some offwhite, some have brownish/purplish base. Some have this dark brown dorsum and others tan. Are all mappas found in the philippines just the typical mappa mappa? HOw is a mappa rosea identified? What is the best best way to group these mappas.

C. mappa rosea is characterized by a distinctive purple base, or at least large purple patches on the base and margins; finer marginal spotting than in other mappa forms; and an orange to reddish aperture, including the teeth. It is from the southern Indian Ocean.

Thanks much Paul. I'm really learning alot from you.
