Type species.

Antixoon cribripenne Gorham, 1886 (sub Melyridae ) [by monotypy] (not included in Léveillé 1910)

Crowson, R. A. 1964a: 291 (key). Kolibáč, J. 2005: 47. Kolibáč, J. 2006: 116 (phylogeny)

Remarks.

In consideration of a recent re-classification of Eronyxa within Lophocaterini ( Tait et al. 1990), the systematic position of Antixoon needs to be checked. However, the bifid tarsal claws correspond with Crowson’s (1964a) opinion about a close relationship between Antixoon , Diotolobus and Decamerus .
