The Helosciomyzidae are comprised of 9 genera and 22 species. Except for one South American genus (Sciogriphoneura Malloch) with 2 species, the family occurs only in Australia, Tasmania, New Zealand, the Snares, and the Auckland Islands. The highly restricted species distributions and morphological diversity of the family suggest a relatively ancient origin.

Little information is available on the biology and immature stages of helosciomyzids. Knutson described the puparia and associated larval structures of Eurotocus australis and Helosciomyza australica, and Steyskal described the egg of H. ferruginea (Steyskal & Knutson 1979). Puparia of E. australis have been reared from larvae obtained from agaric fungi. Barnes (1980b) reported rearing H. subalpina on various dead insects and live ant larvae and described the immature stages. Barnes (1980c) reported Polytocus costatus larvae from the carcass of a seabird and described the larvae and puparia.
