Karenni, Myanmar

.

Previously thought to be possibly closer to Palearctic “S. europaea group” than to the brightly coloured predominantly tropical S. azurea and S. formosa, but genetic analysis places this species as sister to North American S. carolinensis#R. Races presumed to intergrade in S China (SW Yunnan). Two subspecies recognized.

Subspecies and Distribution
  • S. m. ligea Deignan, 1938 – S China in extreme S Sichuan (Yanyuan and Miyi), W & S Yunnan (S to Longpeng and S Xishuangbanna) and extreme SW Guizhou (Xingyi, near Qianxinan).
  • S. m. magna Wardlaw-Ramsay, 1876 – C & E Myanmar (S from Mogok Hills, E from Menetaung Range and Kalaw, to Mt Nattaung, in N Karen), adjacent S China (SW Yunnan) and NW Thailand.
