Unfortunately ...no.I suspect it will all be settled in the near future with D.N.A. but I don't know exactly when.I don't know if I agree with all the recent changes allowing D.N.A. to stand alone but using it as a component to differentiate animals whose morphology is so obviously similar is valid,and can't be argued.
With this complex and other species people use color and minor fluctuations in pattern to seperate the "subspecies".This is unacceptable, if it weren't there would be no need for keys of any kind,all we would need is picture books.Can you imagine the definitive work on Gekkonids being published by the likes of someone like TFH or Barrons?People should not use books by hobbyists to define species,unless written by someone credible.Too much room for error(personal,editorial,etc.)The fact is there has yet to be a good book on Phelsuma published.Just because there isn't a better one out or said book is the best one out really doesn't matter to me.I judge most things on their own merits,this includes books.If you want to compare them to one another let's do so.Comparatively all Phelsuma books are similar, they all suck, no difference,you might as well be watching 10 different remakes of Starsky and Hutch.They might be a little different with different actors but the characters are the same and the plot still sucks.The goal has simply not been met.I can think of a few people who are qualified to write such a book but it would certainly have to be a collaboration.The problem is that people are too busy with their animals.The other is that serious enthusiasts are too critical of themselves and strive for perfection.I think if you can't come remotely close to that goal(perfection) you shouldn't write a book,especially just to get your name in print.I think even the most recent (Professional Breeders series)is subpar.It lacks massive amounts of information but is an ok picture book.They call this a bait and switch.Put a bunch of pics in a book to make you think it has some substance.I mean the very name is misleading because to my knowledge none of the authors of any book in that series is a professional breeder and professional breeders don't use them as a reference.I mean if you are allready breeding an animal professionally you don't usually need to read about it to learn how to breed it. Kind of a "smoke and mirrors" act.These might be ok books for beginning hobbyists but beginning or intermediate hobbyists shouldn't argue speculative issues of taxonomy.Know your place,pay your dues crawl before you walk...call it what you will but don't argue opinions.Don't ever refer to a book like Greg and Leannes',Sean McKweown's The General Care and Maintenance of Day Geckos or Rundquist's Day Geckos by TFH to support your opinion and don't defend anything you learn from such erroneous literary works.They are full of conjecture lacking hugely in fact most don't realize it because they don't know better.
By the way,Matt,good to see you back around.Hope it's for good,there are too many mouthy punks in the hobby these days and we need some balance.
