A section of sixteen color plates completes the picture of the external morphology of millipedes and gives an account of their amazing mega-diversity. The book is well illustrated with near 300 light, TEM and SEM micrographs and line drawings. Near 15 tables summarize the leading information, including a final large table giving an overview of the suprageneric millipede taxa. Each of the [...] chapters is a deep and updated review, fully referenced with a list of references at the end (80 pages in all, about 1,600 titles). All the co-authors are renowned experts, morphologists, ecologists, taxonomists and biogeographers, leading specialists on the topics they discuss. To conclude, coupled with the first volume of the monograph, this book is an excellent tool of reference not only for myriapodologists, but also for those who are interested in the biology, ecology and evolution of soil arthropods and soil biology in general. We are, therefore, grateful to Sandro Minelli for finally completing his editorial project, planned long time ago, of an updated treatise on Myriapoda (as he tell us in the preface of the first volume), thus filling a nearly century-long gap in the modern zoological literature about this intriguing group of arthropods.Marzio Zapparoli, in: Fragmenta entomologica, 48 (1): 87-88 (2016).
