Topic: Water beetle Ochthebius subinteger
Ochthebius subinteger and O. lejolisii both appear in the NBN species dictionary, with more records attributed to subinteger. Ochthebius lejolisii used to be considered a subspecies of subinteger but was raised to species level years ago. For example, see the 2008 Duff beetle checklist. The true Ochthebius subinteger is not a British species.
