is a genus with species reported from all the continents except Australia although biogeography of the genus indicates larger distribution in subtropical to temperate regions (Fig. 8). The individuals have been found to inhabit soil, fresh and polluted water and more specifically reported from aquatic mulm or slime flux or sewage; from soil to rotten decaying matter or from moist husk to rotten plants and from dung to frass of beetles. Most species are bacteriophagous but like other diplogastrids, may also feed on protozoa, fungi and nematodes (

n. sp. shows hermaphrodite females and males in the population. It demonstrates a gradual reduction in posterior genital branch in several specimens up to the extent of a reminiscent post-uterine sac. Such unique feature indicates towards its transitional status in the evolutionary process showing affinities to both the related yet distinct genera
