| Summary: | Figure 1. Known (solid lines) and projected (dashed lines) indigenous distributions of the Diplopoda showing locations of significant fossils. The solid line in southern South America shows the extent of diplopod samplings and known occurrences, but we project the organisms for uninvestigated areas south of the southernmost records, in Isla Grande de Chiloé, Chile, and Santa Cruz Prov., Argentina, the unsubstantiated record of the polyxenid from the last (Mauriès 1998), Propolyxenus patagonicus (Silvestri, 1903), being indicated by the question mark. Except for records from Kodiak Island, Alaska (Chordeumatida) (left arrow), the Hawaiian Islands (Cambalidea), and the Federal Republic of the Marshall Islands (Polyxenida) (right arrow), oceanic islands and archipelagos harboring ostensibly indigenous forms are grouped with the continent with apparent faunal affinity; the Cape Verde Islands are combined with both Africa and Europe because of dual affinities, Spirostreptidea and Glomerida/ Julida, respectively. Only a few records and samples, especially of Chilognatha, are available from the dotted areas in Africa and North America; no extant records and samples are available from those in Eurasia and South America. The southeast Asian area encircled by triangles is the only place where all 16 orders occur indigenously. Upright triangle, site of Archidesmus macnioli Peach, 1887, the oldest helminthomorph fossil, from Silurian deposits in Scotland; Star, site of the non-spinose oniscomorph pentazonian Carboniferous fossil at Mazon Creek, Illinois, USA; Inverted triangle, approximate location of Gobiulus sabulosus Dzik, 1975, the Cretaceous spirobolidan fossil in Mongolia; Asterisk, location of Protosilvestria sculpta, the Oligocene cambalidean fossil from Quercy, France (Mauriès 1992). : Published as part of Shelley, Rowland M. & Golovatch, Sergei I., 2011, Atlas of Myriapod Biogeography.
