Abstract 

The morphology of the larval mandibular structures of the family Lycidae 
(Polyphaga) is characterized by facultative dicondyly, posterior articulation 
with long mandibular rods, lateral location of the anterior condyle and its 
articulation with a paired non-cranial structure. It is compared to that of 
Eucrustacea, Chilopoda, Entognatha, Microcoryphia and Zygentoma and found 
to be more reminiscent of the Entognatha. The phylogenetic implications of 
this conclusion are discussed, with the Pterygota and Dicondylia hypothesized 
to be non-monophyletic.
