Abstract
Hypoponera is a genus of ponerine ants, well known for its simplified morphology, lacking any clear autopomorphy, and its cosmopolitan distribution. Here we describe the first Hypoponera in Dominican amber. The discovery of Hypoponera electrocacica sp. nov. confirms the long-expected presence of the genus in the Caribbean Miocene. The modern diversity of Hypoponera in the Greater Antilles now stands at five species and two putative subspecies.
The dataset here corresponds to reconstructed Micro-CT scan data for the Holotype specimen (MNHNSD FOS 18.126) of Hypoponera electrocacica sp. nov.

Description of the data and file structure
Supplementary files contain MicroCT data for holotype MNHNSD FOS 18.126. We obtained X-ray-based computed tomographic (CT) images of the holotype specimen at the New Jersey Institute of Technology Otto H. York Center for Environmental Engineering and Science, using a Bruker SkyScan 1275 micro-CT scanner. We scanned the specimen at a voltage of 25 kV and a current of 175 μA for 400 ms exposure times averaged over 5 frames per rotation with a voxel size of 5.96 μm. Z-stacks were generated using NRecon (Micro Photonics, Allentown, PA) and reconstructed using 3D Slicer v5.9 (Fedorov et al. 2012).
Data correspond to:
