Hosts: In Quercus , section Quercus : Q. deserticola Trel. , Q. glabrescens × obtusata , Q. glaucoides M. Martens and Galeotti , Q. laeta Liebm. , Q. magnoliifolia Née , Q. resinosa Née and Q. rugosa Née ( Quercus section); after a reexamen of host by S. Valencia-A, the host mentioned in Pujade-Villar et al. (2011, Q. mexicana Humb. and Bonpl. ) is wrong, the correct host is Q. deserticola Trel. All host are new records from this species.

Distribution: México, described from material collected in the Parque Nacional del Bosque del Pedregal (Bosque de Tlalpan, Ciudad de México). Its distribution is extended to have collected it in the states of Hidalgo, Jalisco, Michioacan, Morelos, Puebla and Zacatecas.

Remarks: Adults of this species have high morphological variability in the following characters: (i) the color is very variable, usually is ambarine with black marks but some specimens lacks black marks and others are almost black; (ii) OOL is usually shorter than diameter of posterior ocelli, but in some specimens OOL is larger; (iii) the length of notauli are usually short reaching the tegulae level but in some specimens are longer reaching until 3/4 of mesoscutum length; (vi) the metasoma sculpture is usually striated in second metasomal tergite but is some specimens exist also a reticulate sculpture more or less extended from margin of this tergite towards the basal area; (v) usually the second metasomal tergite is completely sculptured but in some specimens there is smooth in dorsal small area. The authors suggest that this variability may be indicative of a group of species. Further research should asses this matter.
