Ceroptres quercus-tuber (Fitch) Weld, 1951 . U. S. Dept. Agr., Agr. Monog. 2: 614. Ceroptres quercustuber (Fitch) Burks in Krombein et al. 1979 . Smithson. Ins. Press : 1065. Distribution. USA . State of New York , according to Burks (1979) . Biology. Reared from galls of Callirhytis clavula ( Osten-Sacken, 1865 ) on Q. alba , according to Osten-Sacken (1865: 350) . Remarks. The type material of this species is presumably lost; it was originally deposited in USNM, but now the box of types is empty, and their current location is unknown (M. Buffington pers. comm.). Furthermore, Fitch’s original description (1859: 806) for Cynips q. tuber is very poor and thus insufficient to distinguish this species from the rest of Ceroptres , and even to establish whether it really belongs to Ceroptres . Osten-Sacken (1865: 370) , who transferred the species to Ceroptres , says nothing new about its morphology. Hence, we here propose to place Ceroptres quercustuber ( Fitch, 1859 ) as incertae sedis until the original material is found and studied.
