Abstract

The first instar larva (triungulin) of Euzonitis rubida (Ménétriés, 1832) is described and illustrated. This is the first description of a triungulin of the nemognathine genus Euzonitis Semenow, 1893. This larva is very similar to that of the genus Zonitis Fabricius, 1775, the distinction of these two genera remaining difficult by using both larval and adult features. The examination at the scanning electron microscope of several characters of these and other genera of the subfamily Nemognathinae, confirms themain distinction of tribes, but better outlines the condition of some features previously incorrectly defined. Additional species of some genera were also examined and partially figured.
