A New Bicolor Species of the Ant Genus Temnothorax Mayr, 1861 (Hymenoptera: Formicidae) from Yunnan, China

In this paper, we described a new species, T. gui sp. nov. Wei, Wu, Zhong, & Huang, 2024, of the genus Temnothorax Mayr, 1861 from China. The new species is closely related to T. leyeensis Zhou, Huang, Yu, & Liu, 2010, but can be distinguished by the following characters: (1) Head with sculpture is simpler and lustrous, with relatively sparse and fine reticulated sculpture throughout. (2) Promesonotum in dorsal view only irregularly reticulate not interspersed with fine reticulation centrally. (3) Gaster smooth and shiny, without coarse sculpture anteriorly. (4) Colour of mesosoma reddish, instead of orange.
