I agree John, L. guichenoti. I would add that the larger grey flecks on the back towards the front of the body are not as obvious as they usually are in guichenoti and the absence of a dark mid-vertebral stripe makes it a harder identification. But not all L. guichenoti have the mid-vertebral dark line (e.g. photos in Robertson and Coventry 2019). The grey flecks lower down on the back and on the tail are more typical of guichenoti. So yes I agree it is guichenoti.
