The leaf mine ( Fig. 15) is typical of this genus; the white markings on the forewings are dark-margined externally ( Figs. 16, 22); and the apex of the tegumen bears the diagnostic pair of setae ( Fig. 17). Sternum VIII is entire rather than bifid caudally, but the latter character is not present in all  Camerariaspecies.   Host. Fagaceae:  Quercus hypoleucoidesA. Camus.   Distribution. USA: AZ, NM.  Review.The single type( Fig. 22) was “reared from a blotch mine on the upper side of a leaf of oak,  Quercus hypoleuca, White House Canyon, Santa Rita Mountains, Arizona” ( Braun 1925a).  Quercus hypoleucaEngelm.is a synonym of  Q. hypoleucoides. DRD reared 23 adultsof  Cameraria cretaceellafrom mines on  Quercus hypoleucoidescollected on 22 July 1989in the Gila National Forest, Catron Co., New Mexico. Adults emerged from 22 July to 11 August. The male and female genitalia figured herein ( Figs. 17–21) are from those specimens. CSE also reared seven adults of C. cre- taceellafrom mines on  Q. hypoleucoidescollected from 2 to 14 March 2017at Cave Creek Canyon (Cochise Co.), Madera Canyon, and Ramsey Canyon, Arizona( Figs. 15, 24). They emerged from 24 March to 5 April, earlier than Braun’s (1925a)emergence date of 12 April.   Comments.No other gracillariid has been reared from  Quercus hypoleucoides, although we have found uppersurface linear-blotch mines of an undetermined  Acrocercopson this host at Madera Canyon.All of our collections of  Camerariamines from other Arizonaoaks (  Q. arizonicaSarg.,  Q. emoryiTorr.,  Q. oblongifoliaTorr.) have yielded other, predominantly brown species.
