Development patterns can be useful for identification in Diplopoda, but they are rarely studied for Neotropical species. The present paper brings the identification of the developmental stadia of two Neotropical species, the parthenogenetic diplopod Poratia salvator Golovatch & Sierwald, 2000 and the bisexual species Myrmecodesmus hastatus Schubart, 1945. Both species occur in floodable areas in the Pantanal of Mato Grosso, Brazil. Poratia salvator presents seven developmental stadia; the adult (the last stadium) possesses 17 rings, of which 16 are podous, most of them with two pairs of legs. Only one apodous ring is present - the collum - which is present since the first developmental stadium. Myrmecodesmus hastatus presents eight developmental stadia; the adult (the last stadium) possesses 18 rings, of which 17 are podous, most of them with two pairs of legs. Only one apodous ring is present - the collum - that is present since the first developmental stadium. Both species present anamorphic post-embryonic development, of the teloanamorphic type, which means that new rings are added up to the last developmental stadium
