description: Lepidocyrtus “ lignorum group” species key
Among the European Lepidocyrtus the “ lignorum group” could be defined by the dorsal macrochaetae formula R0R1R2/00/0101+3 (with or without cephalic macrochaeta So). This group is composed by the species L. instratus, L. lignorum, L. peisonis Traser & Christian, 1992, L. ruber Schött, 1902, L. tellecheae, L. uzeli Rusek, 1985 and L. violaceus (see Mateos 2008a), to which the new species L. juliae sp. nov. and L. barbulus sp. nov. must be added. The first described species of the group was L. lignorum, and so the group gets its name.
