I try to collect data from fresh DORs I encounter here in South Texas; I recorded number of tail rings on fewer than half of the specimens I have dissected (so there was no uncertainty about the sex).

Of the data on 16 specimens I have handy here on the computer, 11 were males, 5 females (all from South Texas "brush country").

Males: range: 4-6
mean: 5.5
mode: 6

Females: range: 4-5
mean: 4.4
mode: 4

Two females had 5 tail rings, 3 males had 5 rings
One male had 4 rings

To me this character shows too much overlap to be of much use in definitely establishing the sex of an animal. When I have a captive that I absolutely can't sex visually, I usually wait for a shed and count the number of subcaudals; with atrox, this is much more reliable. Based on your counts, I would also say that there appears to be some geographical variation to consider as well.
