Abstract

The tribe Scydmaenini is the second most diverse group of the ant-like stone beetle subfamily Scydmaeninae, with more than 730 extant species classified in seven extant genera (Newton, 2019). However, confirmed fossil records important for elucidating the evolutionary history of the tribe are extremely rare, represented by only two species previously reported from mid-Cretaceous Myanmar amber (Yin et al., 2018; Yin & Cai, 2019). Provided in this paper is the description of a third fossil species of Scydmaenini, again from Burmese amber, which sheds new light on the palaeodiversity and morphological disparity of this group during its early evolutionary stage.
