Abstract:
A new small-bodied beetle, Multispinus parvus sp. nov., is described from the mid-Cretaceous Burmese amber and assigned to Mordellidae (Coleoptera: Tenebrionoidea). Based on a careful re-examination of the Mordellidae and mordellid-like beetles from the Burmese amber and analysis of their morphological characters, the family Apotomouridae is reduced herein to a subfamily of Mordellidae as Apotomourinae. The absence of a pygidium in Apotomourinae cannot be regarded as a synap-omorphy. All known mordellids found in the mid-Cretaceous ambers are all small in size, which may be related to the mid-Cretaceous ecological environment and the early angiosperm flower morphology in their habitat.
