Nice pics and I counted 84 subcaudals. Triple checked the count the best I could from pic#2 and the zoomed in pic from Steve. Now I need my probe set. Your pics #3 and #4 show clear indentations laterally with a slight hint of a bulge at the dorsal aspect above the cloacal region. Therefore I will presume this snake is male. Congrats. Great photos. There is always one more difficult to identify than most others.
