[Taxacom] Global counts of accepted genera

[Peter Uetz]

Tony,

Of the 40, you list …
— 15 as fossil
— 11 as unaccepted or uncertain (the latter actually are all not accepted)
— 9 as accepted and they are (including 1 subgenus, Abaculabronia, not counting), i.e. 22.5% correctly identified as accepted
— 5 as accepted while they are actually NOT

The 9 are:
Ablepharus 
Abronia Acalyptophis 
Acanthocercus 
Acanthochelys 
Acanthodactylus 
Acanthophis 
Acanthosaura 
	(Abaculabronia )

> So of these initial 40 names, we have 22 "accepted", 7 "unaccepted" (known synonyms in the main), and 11 "uncertain", which split into 5 extant and 6 fossil. According to the protocol adopted for the "Megataxa" paper, we would report the estimated (mean) total accepted names at 22+5.5 (half of the "uncertain" total), rounded up to 28, with an uncertainty range of +/-5.5 (rounded up to 6).

> So to refine this estimate (effectively of somewhere between 22 and 33 accepted names), we need additional information on the 11 "uncertain" names which I do not have to hand at this time, but may take a look as I have a little time - or someone else can :)  The same someone, or another, might also care to comment whether the names flagged "accepted" / "unaccepted" are correctly so, as well.

>  Also of interest to note, of the 22 names listed as "accepted", 9 (41%) are fossil, which is not that far from the overall value (48.9%) given for all accepted names in Reptilia in the paper (around 4,000 accepted names).
