Localities of the species studied and structure of their genital tracts. a World map showing the distribution of Peripatidae and Peripatopsidae (areas in dark gray, modified from refs [2, 75]) and the localities of gen. sp. 1 and gen. sp. 2 collected in Colombia (orange dot), and E. rowelli collected in Australia (blue dot). b, c Diagrams of the reproductive tracts in placentotrophic viviparous peripatids (B, modified from refs [27, 39]) and combined lecithotrophic/matrotrophic viviparous peripatopsids (C). Only one horn of the paired uteri is shown in each diagram. Embryonic stages according to refs [15, 31], respectively. Asterisks indicate unfertilized eggs or undeveloped embryos, which occur frequently in E. rowelli. Abbreviations: d, distal; p, proximal
