Myrmecina gaoligongensis

At present, this species is known only from the Gaoligong Shan Mountains in Yunnan, China. The type locality is a montane forest on Tiantan Shan Mountain, situated at an elevation range from 1400 to 1800 m. Four workers of the new species were collected from a leaf litter extraction at 1800 m altitude, and the other three from a leaf litter sample at 1400 m. Nothing specific is known about its ecology.
