Leaf mine. On the lower leaf surface; according to Braun (1916) the larva “consumes the entire leaf substance within the mine and at maturity throws the lower epidermis into several folds between which are numerous fine wrinkles.”

Generic placement. Braun (1908) correctly placed Lithocolletis leucothorax  in her Group I. Davis (1983) proposed the new combination Cameraria leucothorax  . Gates et al. (2002) used the name “ Phyllonorycter leucothorax (Wlsm.)  ”, but they did not indicate this as a new combination, and the species has otherwise continued to be placed in Cameraria ( De Prins & De Prins 2019)  . The placement in Phyllonorycter  is supported by the underside tentiform leaf mine, the proximally dark-margined white forewing markings ( Figs. 43–44View FIGURES 43–44), and the absence of setae on the tegumen ( Fig. 45View FIGURES 45–49).

Hosts. Fagaceae  : Notholithocarpus densiflorus (Hook. & Arn.) P.S. Manos, C.H. Cannon, & S.H. Oh var. echinoides  (R.Br. ter) P.S. Manos, C.H. Cannon & S.H. Oh, Quercus chrysolepis Liebm. 

Distribution. USA: CA, OR.

Review. Walsingham (1907) described this species from an adult caught in the Santa Cruz Mountains of California. Braun (1908) cited additional specimens from Placer Co. Braun (1916) reared adults from wrinkled underside mines on Notholithocarpus densiflorus var. echinoides  (as Quercus densiflora var. echinoides Sargent  ) collected at Upper Klamath Lake, Oregon on 8 August 1915. Opler (1974) recorded this species from Quercus chrysolepis  , noting that DRD had compared his reared material with the type and had found the specimens to be conspecific. Gates et al. (2002) also listed Phyllonorycter leucothorax  as forming lower-surface mines on Q. chrysolepis  .
