  Theclinae is a subfamily of Lycaenidae butterflies comprising hairstreaks, elfins, and related groups. Members are characterized by small to medium size, often with tail-like projections on the hindwings and intricate underside patterns. Many species exhibit myrmecophilous relationships with ants, and larvae possess a specialized dorsal gland (Newcomer's gland) that secretes sugary fluids to attract ant protectors. The group shows high diversity in tropical regions, particularly the Neotropics and Southeast Asia, with fewer migratory species compared to other butterfly groups.
