| Possibly, C. zeylanicum White, 1855, though the specimens I have got have a denser pubescence at each side of the pronotum, like this. |

Holzschuh's last paper described a number of new Ceresium from Sabah. You might be able to match your specimen to one of those.
Ceresium zeylanicum was not found in a very large series of this genus which he studied leading him to believe (personal communication) that it doesn't occur in Borneo, and is possibly restricted to the Indian subcontinent. Therefore all records of Ceresium zeylanicum from outside regions are possibly based on misidentifications of similar species. |

Hallo Dan, you were right.
After Holzschuh, 2011 is the specimen at the left side Ceresium indigum Holzschuh, 2011. The Male is distinguished by the two distinctly extensions on the 8 Sternit.
The specimen at the right side is in my opinion Ceresium mediocre Holzschuh, 2011. |

To make matters more difficult, there are at least 8 additional Ceresium (or closely related Callidiopini) species in my collection from Sabah which do not match any of the species that Holzschuh returned to me last year.
This genus is quite a challenge like the American Anelaphus or even Aneflomorpha |

Borneo, Ceresium: indigum & mediocre?
