Campatonema Jones

Campatonema Jones, 1921: 334 . Type species, Campatonema marginata Jones

(1921) (by monotypy).

Pitkin (2002) characterized Campatonema by its peculiar furca (tapered, pointed shape), by the shape of the band on the dorsal forewing, and by the pointed, creamcolored forewing. In the three new species the furca is typical, of the Ourapterygini and located near the middle of the juxta and able to deflect to either side. The shape of the dark band on the dorsal forewing is variable among species, and the creamcolored forewing can be overlaid with reddish-brown scaling. The pointed forewing is characteristic. The unusual setal arrangement on the antenna with two rows of setae per segment on the ventral surface is a useful character for separating species of Campatonema from similar looking species in other genera. The genitalia are rather simple and have few characters useful for diagnosing the genus, so members of the genus are most easily recognized by a combination of wing shape, maculation, and antennal structure.
