Temascáltepec and Real del Monte, Mexico.
Taxonomy somewhat confused, and precise distributions of races not well known. Probably a sister-species of L. clemenciae#R. Race margaritae sometimes suggested as possibly a separate species (including salvini and nobilis as races): has gorget bluish-violet, not rose-pink, may call slightly differently, and may be sympatric with nominate amethystinus in S Oaxaca#R; on other hand, a study of phylogeography and population genetics of this species indicated that variation in throat colour is of recent origin and probably based on only minor genetic differences#R; research clearly needed. Proposed race brevirostris doubtfully distinct from margaritae. Name of race circumventus sometimes misspelt as circumventris. Five subspecies recognized.
