Comments

Megalognatha festiva was recently redescribed by Grobbelaar (1993). The syntype of Crioceris virens was compared with the Fabrician type specimen of Cistela festiva deposited in the BMNH and without any doubt the two taxa are conspecific. Crioceris virens is proposed as a new synonym of Megalognatha festiva .
