C. Fischer, The disc-like organ of the Lestoniidae (Heteroptera : Pentatomoidea), withremarks on lestoniid relationships, IN SYST EVO, 31(2), 2000, pp. 201-208
The morphology of the 'disc-like organ' of Lestonia haustorifera is describ
ed on the basis of SEM-techniques. There is evidence for a gland function o
f this organ. The homology of the disc-like organ of Lestoniidae with Pende
rgrast's organ of Acanthosomatidae and the phylogenetic relationships of Le
stoniidae within Pentatomoidea are discussed.
