Remarks
|
|
P. membranifera is an accomplished tramp species. It has been recorded widely from tropical and warm temperate regions of the world. Brown & Wilson (1959) suggested an African origin, but this was questioned by Bolton (1983). This species is found in the soil of rather open habitats. Japanese records are generally from the south, ranging northwards to southern Honshu. The most northern record is from Tokyo (Kubota & Terayama, 1988). Wilson (1954) reported P. membranifera feeding on a wide range of small soft-bodied arthropods.
