Dendrobates groups

[Knighty]

Doing some evening research for my website and I stumbled accross a section which kind of confused me. I have the full break down of dendrobate taxonomy into family, sub family and species and then i found a site breaking them down into groups. It was very hard to make head or tail of this as all the names were pre 2006 revision. Basicaly it had the genuses then it broke them into groups and explained the difference, the groups were.........

HISTRIONICUS
QUINQUEVITTATUS
TINCTORIUS
FEMORALIS
MACULATUS
PETERSI
PICTUS
TRIVITTATUS

here is a link to the page www.poison-frogs.com, a 2002 website dedicated to dart poison frogs and rainforest vivaria, together with lots of pictures, films and more. Descriptions of all dendrobates , epipedobates, phylobates, leucomelas, azureus, pumilio, tinctorius, auratus

Any one able to clear this up or point me at a more up to date page on this

Someone more knowledgeable, please jump in here, but I'd say the grouping is meaningless beyond the author's assertion that inter-species breeding would only likely occur within the "groups".

In my opinion these groups were the result of people in the hobby not feeling that the dendrobatid genera were split up enough. The Grant et al paper addressed this issue in a more scientific manner (at least according to most) by splitting up the original 5-6 genera into 8 or more (not up on the colostethus taxonomy and the aromobates/anomolaglossa taxonomy either). You can kind of see the new genera in the old grouping. The histrionicus group is now pretty much Oophaga. The Quinquevittatus group is now Ranitomeya (though D. quinquevittatus became a member of the genus Adelphobates). The tinctorius group frogs, minus galactonotus, are the frogs left in Dendrobates.
