Note. The coordinates contained on the labels of the reared specimens from ‘Doi Ang Khang’, including the holotype, have a typo (29°54’10’’N instead of 19°54’10’’N), and the correct value is provided in the label citations in square brackets.
Diagnosis. The forewing length is 10.5–11.5 mm in males and 12.5–14.0 mm in females. Cyana yunnanensis regia ssp. n. (Figs 15–19) is externally distinguished from the nominate subspecies (Figs 7–14) by its slightly smaller size, and the less posteriorly curved postmedial line in both sexes. In the male genitalia of the new subspecies (Figs 40, 41), the subbasal diverticulum is considerably more elongate, and the terminal diverticulum is larger than the corresponding structures of C. yunnanensis yunnanensis (Figs 38, 39). The female genitalia of the two subspecies display no remarkable differences (Figs 51, 52).
Distribution. Northern Thailand (Chiang Mai Province) and Northern Laos (Xiangkhouang Province).
Etymology. The subspecific epithet is derived from the Latin ‘regius’ meaning ‘royal’ and refers to the type locality of the new subspecies, The Royal Agricultural Station Angkhang. The name is an adjective in the nominative singular in apposition (Fig. 60).
