Lasius longicirrus

This taxon is considered to be unidentifiable and its identity is uncertain. The type series has been collected on Mount Jishi in Gansu, China, at an elevation of 2100 m. The verbal description and ﬁgures are insufficient. A possible synonymy with either Lasius coloratus, Lasius sichuense or Lasius longipalpus is suggested by sympatric occurrence, the long maxillary palps and long scape. Types were not available from the Agricultural College of Ningxia University. (Seifert, 2020)
