# Mecyclothorax

Mecyclothorax Sharp, 1903 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.
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.
