I think you have possibly two or more species. Your photograph is not good enough.
The two left specimens and the two right specimens are possibly Erythrus sabahanus Vives, 2010. The specimen in the middle may be a different species. But, these may all be the same species, too. There are about 30 described and undescribed Erythrus in Sabah. Most of them are easy to separate, but Holzschuh still has a few descriptions in preparation.
Please separate your species by the shape of the apex of the elytra (rounded, truncate, narrowed, dentate, spinose, etc) and then separate them by features of the pronotum ( protuberances, tomentum, etc ) and apparently the 1st and 3rd specimen are males, the 2nd and 4th specimens are females, but it's impossible to see how long the antennae are on the 5th specimen.
good luck.
