Abstract Recent findings of ommatids from mid-Cretaceous Burmese amber have greatly increased our knowledge on the Mesozoic diversity of Ommatidae.Here, we report the first distinctly miniaturized ommatid species, Miniomma chenkuni gen.et sp.

nov., entombed in mid-Cretaceous amber lovesense 3 from pet calming peanut butter northern Myanmar.This new fossil species is characterized by its small body size (less than 2 mm long) and subglobular metacoxae.

Our discovery of miniaturization in extinct Ommatidae suggests a high ecological diversity of this family in the Mesozoic.
