Abstract
The abdominal lateral line system in Trichoptera, consisting of filame nts and lamellae with associated primary and secondary setae, was stud ied in larvae and pupae of 70 genera representing 26 families. Filamen ts are slender, generally bifid, tubular extensions of the cuticle tha t together form a fringe on the lateral abdominal surface of larvae an d pupae of many but not all families of case-making Trichoptera (Integ ripalpia). Larvae and pupae of the Annulipalpia and Spicipalpia lack a lateral fringe of bifid filaments, but single filaments occur in larv ae of a few unrelated genera. A lateral fringe may help in regulating the now of water which is maintained through the case by abdominal und ulation. Lamellae occur only in larvae of the Integripalpia, where the y are variously distributed among families and genera, and probably ha ve a sensory function. Three types of lamellae are recognized: forked, serrate and single. Filaments and lamellae have significant taxonomic value, and their patterns of occurrence raise questions about the phy logeny of Trichoptera. (C) 1995 The Linnean Society of London
