Mecyclothorax è un genere di Coleoptera della famiglia Carabidae.
Il genere comprende circa 400 specie, delle quali circa la metà è stata scoperta e descritta dall'entomologo della Cornell University James Liebherr (notizia AGI del 22 novembre 2012)Krishna Ramanujan, Researcher discovers 14 new beetle species, su phys.org, 21-11-2012.
Il genere Mecyclothorax è originario dell'Australia.
Descrizione La maggioranza delle specie australiane di Mecyclothorax è in grado di volare, mentre le specie individuate nelle isole Hawaii e nelle Isole della Società sono prive di ali a causa del fenomeno della radiazione adattativa.
I Mecyclothorax sono piccoli coleotteri predatori. Essi subiscono una metamorfosi completa entro il primo mese di vita, cui seguono gli stadi di larva, pupa e adulto. Gli adulti possono vivere fino ad un anno.
Distribuzione e habitat Esemplari del genere Mecyclothorax sono stati trovati in Australia, Nuova Zelanda e nell'isola di Giava, nelle Isole della Società e a Maui (Isole Hawaii). In Australia, sede di origine del genere, sono presenti 25 specie, mentre tra Nuova Zelanda e Giava ve ne sono circa 40. Nelle Hawaii sono state scoperte 239 specie, mentre altre 100 sono state scoperte nelle Isole della Società.
Tassonomia Il genere Mecyclothorax al novembre 2012 comprende circa 400 specie, ma le nuove scoperte si susseguono velocemente.
Al 2011, esso includeva le seguenti 246 specie:
