Some proposed emendations to larval morphology terminology

Despite the publication of an intended consistent terminology for the morphology of chironomid larvae (Saether 1980) as applied in Wiederholm et al (1983), two areas have remained controversial, with inconsistently applied terminology. The first and perhaps most confusing concerns the dorsal head sclerites, the second, the terminology of the mandibular teeth of Tanypodinae. In preparation for the 2nd edition of the Holarctic larval keys, I have attempted to reconcile differing approaches to naming the parts of these larval cephalic structures.
