Distribution
North America. Specific locality data from the original description and subsequent records are sparse. The epithet 'xera' (from Greek 'xeros', meaning dry) may suggest an association with arid or xeric environments, though this has not been explicitly confirmed in published sources.
Similar Taxa
- Hulstina formosataHulstina formosata is the type of the and occurs in western North America; H. xera was described later and distinguished from it by Rindge based on differences in male genitalia and wing pattern.
- Other Boarmiini genera such as Iridopsis and Anavitrinella contain superficially similar brown geometrid moths with mottled forewings; definitive separation requires examination of genitalia and detailed wing venation.

The Hulstina was established by Rindge in 1968, replacing the preoccupied name Hulstia. The epithet 'xera' derives from Greek 'xeros' (dry), though Rindge did not explicitly state the etymological reference in the original description.
