Closely related to L. sybillae, with which has been considered conspecific. Races ovandensis and nubivagus weakly differentiated; perhaps better treated as synonyms of nominate. Proposed race connectens, known from single specimen from N El Salvador, falls within normal range of variation of nominate. Four subspecies currently recognized.

Subspecies and Distribution
