Description of dendrolimnobiontic larvae of Scatopsidae (Diptera) with a review of our knowledge of the preimaginal stages of the family.

Abstract

The 4th instar larva of the Scatopsid Holoplagia richardsi is described. This is the first known larva of genus Holoplagia and the first dendrolimnobiontic larva of the family. The species was reared from larvae collected in a maple tree-hole (Acer pseudoplatanus) filled with water in the vicinity of Grenoble, France, together with another Scatopsid, Ectaetia platyscelis. Both species are rare and are recorded for the first time from France, and even from continental Europe for E. platyscelis. Two other true aquatic larvae of unknown generic and specific placement which were collected in little permanent springs and subsequent brooklets in forested areas of SE France are described. The present knowledge of Scatopsid larvae is summarized and reviewed in the light of these new data. An annotated bibliography of the world literature concerning the immature stages of Scatopsidae is given.
