Kateretid beetles are among the earliest known pollinators of angiosperms that can be traced back to the Cretaceous, but their palaeodiversity remains poorly explored due to the scarcity of fossil evidence. Here we report a new species, Pelretes bicolor sp. nov., from mid-Cretaceous Kachin amber mined in northern Myanmar. The new species is distinguished from the type species Pelretes vivificus most prominently by the elytral disc having a dull trapezoidal mark and 9 parallel punctate grooves on each elytron.

Pelretes 双色 sp。十一月，一种新的短翅花甲虫（鞘翅目：Kateretidae），来自缅甸北部白垩纪中期的琥珀

Kateretid 甲虫是已知最早的被子植物传粉者之一，可以追溯到白垩纪，但由于缺乏化石证据，它们的古多样性仍然缺乏探索。在这里，我们报告了一个新物种，Pelretes bicolor sp。十一月，来自缅甸北部开采的白垩纪中期克钦琥珀。新种与模式种Pelretes vivificus最显着的区别在于鞘翅盘有一个钝的梯形标记和每个鞘翅上 9 个平行的点状凹槽。
