Review of the millipede subfamily Amplininae (Diplopoda, Polydesmida, Aphelidesmidae) with remarks on phylogeny and the description of some new South American genera and species.

A review of the millipede subfamily Amplininae (Diplopoda, Polydesmida, Aphelidesmidae) is presented. The genera Meridiurus, Tribrachiorus, Coleocacamus, Kallistopeltis, Sculptoteles and Pastazina are erected as new. Description of the new species Polylepiscus hirmerae n.sp., Meridiurus venitus n.sp., Tribrachiorus suarezi n.sp., T. huila n.sp., Coleocacamus depressus n.sp., C. labialveus n.sp., Thrinoxethus juani n.sp., T. junini n.sp., T. siolii n.sp. and Pastazina crassa n.sp. are given. Tribrachiorus polygonatus (GERVAIS, 1847), Kallistopeltis kalonota (ATTEMS, 1899), and Sculptoteles braueri (CARL, 1918) are redescribed. An analysis is attempted to elucidate the phylogenetic and, to some extent, biogeographical relationships of the genera as they are conceived of at the present
