Trechus  er en slekt av billene i delgruppen (underfamilien) skyggeløpere (Trechinae) i familiegruppen løpebiller. Sju arter er registret fra Norge. Slekten består av svært mange arter, i Europa er det nær 400 arter, inkludert underarter. I Alpene forkommer det omtrent 80 arter, og flere av dem har en utbredelse som er begrenset til en enkelt fjelltopp.

Utseende 
Artene i Trechus er små dyr, vanligvis lyse og brune på farge av og til litt blå-brunlige. De er små løpebiller, ikke over 6,5 mm.  Antennens fjerde ledd med  fine korte hår og en lang børste/børster i spissen. (Krever forstørrelse for å se). Slekten skiller seg ut fra de andre løpebillene, ved at lengderillen nærmest midten av dekkvingen, bakerst ved spissen, svinger og fortsetter opp i vingen, omtrent der femte lengderille er. Hos de andre løpebillene ender alltid rillene ved bakkanten av dekkvingen.

Utbredelse 
De fleste av artene lever i Palearktis, men slekten forekommer også i fjellområder i Afrika og i Nord-Amerika.
