Leptusa er en slekt av biller som hører til den store underfamilien småkortvinger (Aleocharinae) i familien kortvinger (Staphylinidae). Det er beskrevet mer enn 400 arter, fire av dem er funnet i Norge.
Utseende Forholdsvis små (gjerne 2-4 millimeter lange), middels slanke kortvinger, kroppen nokså jevnbred. På farge er de ofte rødlige eller brunlige. Hodet er ganske bredt med nokså små fasettøyne. Pronotum er bredere enn langt, med rundede sider og hjørner. Dekkvingene er forholdsvis korte og har bakkanten tydelig innbuktet innenfor bakhjørnene. Føttene er fire-leddete.
Levevis Leptusa-artene er vanlige på skogbunnen, og kan også finnes under løs bark på døde trær.
Systematisk inndeling / norske arter Denne artsrike slekten blir delt opp i ca. 80 underslekter.
