Campyloxeninae is a subfamily of click beetles in the family Elateridae. It was established by Cleide Costa in 1975 with the genus Campyloxenus, former member of the tribe Pyrophorini under the subfamily Agrypninae, as the only member.[1] In 2015, genus Malalcahuello was described from Chile as a new member of this subfamily.[2]

Description
editClaws without setae near the base; hind wings with wedge cell; female genitalia with stylus and a very elongate baculum.[3]
The features of Campyloxenus pyrothorax Fairmaire & Germain, 1860 (the only member of the genus Campyloxenus) which distinguish it from members of Pyrophorini are as follows:[4]
| Campyloxenus pyrophorax | Pyrophorini | |
|---|---|---|
| Setae on the claw near the base | Absent | Present |
| Wedge cell on hind-wings | Present | Absent |
| Luminous organs | Present only on prothorax | Present on prothorax and/or abdomen |
| Mesosternal cavity | Almost horizontal | Generally sinusoidal |
