Well done! Looks like you've found the needle in the haystack, CP! There is one species in C&P4 which is Catopyrops ancyra aberrans. The shot of the underside in Fleming seems to match this species quite closely, but the various shots of the specimens in your Taiwanese link is quite close too.

Interestingly, both Fleming and C&P4 say that this species is rare! We saw at least two that day, and SC has also shot it before. Very interesting find...
