Most myriapodologists will know of Illacme plenipes with 750 legs as being the millipede with most legs. Until now that is. Eumillipes persephone Marek 2021 (Polyzoniida, Siphonotidae, Rhinotini) with 1306 legs has just been described in the following paper:
Marek1, P.E., Buzatto, B.A., Shear, W.S., Means, J.C., Black, D.G., Harvey, M.S. and Rodriguez, J. 2021. The first true millipede—1306 legs long. Scientific Reports 11:23126:1-8.
