Identification
Temnothorax himalaicum is related to Temnothorax kashmirensis (based on the original description and photos), but it well distinguished by the sculpture of the head and mesosoma: in T. kashmirensis the head is mostly smooth and shiny, whereas in T. himalaicum only the occiput of the head and the central part of frons is smooth and shiny, the rest of the surface has coarse longitudinal rugulosity. Temnothorax himalaicum has thick, longitudinal coarse reticulate rugae on the mesosoma, in T. kashmirensis the sculpture of mesosoma consists of thiner longitudinal rugae. In addition, T. himalaicum has more sparse hairs on the first gastral tergite than in T. kashmirensis and curved propodeal spines. From all other Himalayan species of Temnothorax, T. himalaicum is distinguished by the long and thin spines of the propodeum, and contrasting bicoloured body, while other species are coloured differently.
