I managed to visit the state of affinis kingdom, i.e. Pahang state with my explorer friend and he brought me to a few locations where affinis could be found. Below is one of such location with specimens which my friend termed as "Pink Rosa" (rosa = rosanervig) in his blog.
The habitat is a small river with flowing water, see below for a short video clip of the habitat.
Both emersed and submersed specimens could be found. The specimens found in this location can be considered as small size as compared to other C. affinis found.
