Abstract The elytral vestiture, pits, and surrounding
integument in representatives of four lucanid subfamilies have been studied.
The vestiture was examined in 35 species and ranged from simple to divided
setae and from smooth to ribbed scales. The pits, examined with SEM in 19
species, varied from small dimple-like indentations to large, sharply
demarcated depressions with raised floors and an ornately sculptured surface.
The elytral ultrastructure is distinctive for genera and for at least one
subfamily. Both the vestiture and pits are simplest in the Lampriminae and most
complex in the Aesalinae. Differences in the elytral surface structures suggest
that the New Zealand aesalines belong in two genera, neither of which is the
Australian genus
Ceratognathus, where they are currently placed.
