Campyloxeninae

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 [species] 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 [species] was described from Chile as a new member of this subfamily.[2]

Description

Claws 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
