Abstract
Two new species of the millipede family Siphonorhinidae, Siphonorhinus globosus sp. nov. and Siphonorhinus peculiaris sp. nov., are described from the mid-Cretaceous Burmese amber. Detailed morphological characters are provided on the basis of 22 specimens, mainly using confocal laser scanning microscopy. The new species can be confidently placed in the extant genus Siphonorhinus based on the head lacking a beak-like rostrum, antennae stout and elbowed; antennomeres 5 and 6 each with a field of basiconic sensilla, and gonopods leg-like, with apical podomere of posterior gonopod divided to two branches. A detailed comparison between the new and extant species is given.
