The peristomatic structures as a source of systematic characters in the genus Lithobius Leach, 1814 (Myriapoda, Chilopoda)

Morphological characters have been widely used in centipede systematics. Here, we aim to obtain morphological information from the preoral chamber and peristomatic structures of lithobiomorph centipedes, with taxonomic sampling focused on the species-rich genus Lithobius Leach, 1814. Towards this goal, we (i) examined the epipharynx and hypopharynx of 32 species belonging to four subgenera of the genus Lithobius , viz. Lithobius Leach, 1814,...
