The first instar larva of Berberomeloe insignis (Charpentier, 1818) is described and figured for the first time and
compared to that of B. majalis (Linnaeus, 1758). Diagnostic larval characters of the genus and of both species are
identified. Morphometric data from different populations are analyzed statistically. Results support species
differentiation and characters definition. Additionally, analyses also suggest that whereas B. majalis is structured in the
Iberian Peninsula, there is a lack of differentiation between Iberian and North African populations
