Dans Donabauer (2017) c'est écrit:
"The Trechus subnotatus group is among the most complicated and confusing groups in the Alps. Important additions have been published in recent years. Three additional species have been recorded from Italy, Slovenia and Austria (Donabauer, 2015): Trechus schwienbacheri (Italy), T. schoenmanni (Slovenia and Austria) and T. andreinii (Italy and Slovenia). Another recently described species, T. kahleni (Donabauer & Lebenbauer 2003) from the Alpi Orobie was synonymized by Degiovanni et al. (2016) with T. binotatus as a dark variation. The latter was removed from synonymy with T. fairmairei. Degiovanni et al. (2016) further identified T. fairmairei to be restricted to a small area around Nice (Nizza) in the western Alps and the common widespread Italian species previously known as T. fairmairei had to be renamed to T. binotatus."
