Zeta 6th letter
alpha, beta, gamma, delta, epsilon and... zeta. Zeta is the 6th greek letter, not 5th.--Miguelferig (talk) 18:41, 5 July 2012 (UTC)

First sentance
This isn't the "6th and most recently described" when there are 7 Classes (Alpha, Beta, Gamma, Delta, Epsilon, Acidithiobacillia and potentially Zeta if it were a validly published name, which I'm not 100% sure it is). 141.163.106.151 (talk) 15:26, 8 July 2016 (UTC)
