Studies on Prionoceridae (Coleoptera: Cleroidea). II. A revision of the genus Prionocerus Perty, 1831 Author Geiser, Michael text Zootaxa 2010 2328 1 48 journal article 10.5281/zenodo.193097 0820809e-5851-4432-9be1-3ce3b512134d 1175-5326 193097 Idgia hirta ( Walker, 1871 ) nomen dubium Prionocerus hirtus Walker, 1871 : 14 . Idgia hirta : Champion, 1919 : 336 . The original description of this species is very poor and the type material seems to be lost (as already noted by Champion (1919)) . It was tentatively placed in Idgia , as a possible senior synonym of I. arabica Champion, 1919 , although it is not from the Arabian peninsula but from the opposite African coast (Tajura is in today's Djibouti ). According to its original description and its type locality, it is highly unlikely to belong to Prionocerus and rather seems to be identical to one of the African species related to I. dimidiata (Gerstaecker, 1871) . As long as the type (if it still exists) is not rediscovered, it must be treated as " nomen dubium ".
