Additions to the Psylloidea of Mexico: Bactericera maculipennis

I report here the first record of Bactericera maculipennis (Crawford, 1910) from Mexico, based on an iNaturalist observation from Ensenada, Baja California. The species, which feeds on various plants in the family Convolvulaceae, was previously known from the western USA (Arizona, California, Colorado, Idaho, Oregon, Washington, Utah) and western Canada (Alberta). Its occurrence in northern Mexico was expected.

The addition brings the number of psylloidea species reported from Mexico to 138.

Bactericera maculipennis may be recognized by its typically Triozid wing venation (vein R+M+Cu trifurcating into veins R, M, and Cu) in addition to the highly angulate wings, large and unusually-shaped cubital cell, and by its wing maculation. Very few triozid species in North America have maculate wings, with the most similar Mexican species being Leuronota inusitata. Both species are illustrated below.
