Poratia
Poratia is a genus of minute polydesmidan millipedes in the family Pyrgodesmidae, characterized by obligate parthenogenetic reproduction via thelytoky. The genus includes Poratia salvator, a small species (3.5 mm length, 0.5 mm width, 19 body segments, brownish-yellow coloration) originally described from El Salvador and recorded from Brazil. Populations exhibit ecological plasticity, inhabiting both strictly terrestrial and periodically inundated environments. Reproduction is independent of males, with extremely skewed sex ratios (approximately 1 male:140 females) and flavobacteria-mediated parthenogenesis demonstrated at the genus level.
