Abstract

A new species of millipede from the family Heterochordeumatidae, Heterochordeuma liae sp. nov., is described from mid-Cretaceous Burmese (Kachin) amber. The detailed morphological characteristics of this species are provided based on the examination of 14 specimens, primarily utilizing confocal laser scanning microscopy. This new species can be confidently assigned to the extant genus Heterochordeuma due to its extended and polydesmidan-like paranota, 32 body rings in male and distinctive curved anterior gonopods, modified coxites 9, and leg-pair 10. A comprehensive comparison with extant species is also presented.
