Porophila malkiniW. Eugene Hall
Porophila currently consists of one described species, P. malkini (Dybas, 1956), which inhabits the northwestern United States. The type series was collected on a polypore fungus, Fomes pinicola.
Porophila can be distinguished from other nanosellines by the following characters: 11-segmented antennae; pygidial spine consisting of a lobe flanked by a wide 'tooth' on each side; mesosternal process not extending beyond the mesocoxae, thus lacking the narrow mesosternal 'spine' which is present in Cylindrosella and Nanosella.
Porophila malkini has been collected in Oregon, Coos and Lane counties (Dybas, 1956). A soon to be published record also notes the species to occur in California (Mendocino County).
