Ontogeny and morphological diversity in immature mites: Preface to Part V with a summary of contributions so far

摘要

It is my great pleasure to present to you the fifth part in this series of special volumes on mite ontogeny and morphological diversity (Zhang et al. 2018, 2019, 1920a,b). Despite the global COVID-19 pandemic, our ontogeny enthusiasts managed to continue their research and contributed eight papers to this volume, with one paper on Mesostigmata (Zhang et al. 2021), five papers on Oribatida (Bayartogtokh et al. 2021a,b; Seniczak, S., Ivan, Marquardt Seniczak, A. 2021a,b; Seniczak, A. Seniczak, S. 2021) and two papers on Trombidiformes (Negm Gotoh 2021; Xu Zhang 2021).
