Five new species of the giant pill-millipedes of the genera <i>Zephronia</i> and <i>Sphaerobelum</i>, from China (Diplopoda: Sphaerotheriida: Zephroniidae)

Five new species of giant pill-millipedes in the family Zephroniidae are described and illustrated from China: <i>Zephronia medogensis</i> Zhao &amp; Liu <b>n. sp.</b>, <i>Z. zhouae</i> Zhao &amp; Liu <b>n. sp.</b>, <i>Z. hui</i> Liu &amp; Wesener <b>n. sp.</b>, <i>Sphaerobelum benqii</i> Liu &amp; Wesener <b>n. sp.</b> and <i>S. tujiaphilum</i> Zhao &amp; Liu <b>n. sp.</b> COI sequences of these five new species are given and deposited in GenBank. Additionally, a study of the genetic distance and a molecular maximum likelihood analysis were conducted based on DNA barcoding data of most SE Asian Sphaerotheriida species.
