| I have this species in my collection, along with several very similar species. There are many undescribed Ceresium in Borneo, too. I'll try to get a name for this later. |

| It looks like Ceresium humerale Schwarzer, 1931. Holzschuh has identified many of my Ceresium species, and he undoubtedly studied the types before he described some new species from Sabah. The pubescence and punctation on the pronotum, as well as the shape and size of the pronotum can be used to separate the species. And if the pubescence on the pronotum has been rubbed off, it becomes impossible to identify these species. At this time, I have about 10 Callidiopini (mostly Ceresium) from Sabah that I can't identify. I'm sure there must be many more new species there. |

This is the type of C. aemulator. The pronotom has a small, longitudinal callous in the basal central area. This type of character is usually a diagnostic feature on species of Ceresium. The differences between some Ceresium species is very subtle.
