Larvae of new zealand fanniidae (Diptera: Calyptrata)

Abstract

Larvae of 9 species are described and illustrated. They are Euryomma peregrinum (Mei- gen), Fannia albitarsis Stein, F. canicularis (Linnaeus), and 6 unnamed species of which 5 are endemic. The larvae living in guano of the New Zealand short-tailed bat have retained a circular posterior spiracular plate with a typical cyclorrha- phous arrangement of the spiracular openings. Larvae of a subantarctic species have as many as 20 lobes on the anterior spiracle. The morphology and possible role of the paired segmental outgrowths of fanniid larvae are discussed. © 1984 Taylor & Francis Group, LLC.
