Campyloxeninae
Hind-wings of Neotropic elaterids; ones of Campyloxenus pyrothorax (fig. 155) have 'wedge cell' (annotated as W), which those of members of the tribe Pyrophorini (subfamily Agrypninae; figs. 156–160) lack.

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. In 2015, genus Malalcahuello was described from Chile as a new member of this subfamily.

Description

Claws without setae near the base; hind wings with wedge cell; female genitalia with stylus and a very elongate baculum.

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:

	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
