My initial thought was rubripinnis, so much so that I didnt even click on the pic to look closer, then this afternoon someone brought it to my attention again. Looking at the pattern on the back half of the dorsal, it is the same pattern found on tonozukai. The blue on the underside, I dont think matters much, as males of the complex have been shown to have blue to varying degrees, although this is certainly on the heavy side. It lacks the elongated middle dorsal filaments of tonozukai, but there could be a number of reasons for that, and even though I personally identify myself as a seperator of species, I dont feel there are enough differences for cf. tonozukai to be seperated from "true" tonozukai. As of now I am saying C. tonozukai.
