As CC mentioned, there is alot of varients within the ssp infuscatus. Ive seen everything from animals that look ALMOST identicle to lubricus al the way to your typical ones. I think the main characteristic is the fadeing pattern and poorly defined banding. Also, some sort of darkening of thre head. Even my infscatus's head has much less defind markings and darker coloration then the lubricus. (as a side note, it seems most of the infuscatus I have seen which were similar to mine had two pinkish spots on the head. They have seemed to have faded in my male but when he was a neo, they were very apparent and I have seen simlar adults retain it. Havent seen this in any lubricus though)
As for intergrades, the bulk that I have seen were bright red or orange in base color but with the scattered banding almost ideticle to yours and a pitch blk head. Kinda neat looking if ya ask me. I think bud produced some awhile back and may have a pic if you want to see what im reffering too)
Its really hard to tell when you have a neonate, expecially like the one I have(which is now an adult). He was identicle to a lubricus but as he grew, darkend and faded (though not all that much compared to some). Even Susan Hunter told me I was full of it and had a lub
Proved her wrong!!! LOL Susan!!
BTW, glad you dug the lubricus pic. I now have a trio of lubs, 1 male infuscatus and im picking up 4 neonate lubricus in Daytona. Should have a nice breeding colony the year after next.
