Temnothorax manni

The types were collected at an elevation of 2600-2800 m (8,500-9,000') (Wheeler, 1914). The area was wooded with oaks and pines. The deeper canyons were riparian, but the hillsides were dry.

Identification
Mackay (2000): " The workers of this species are concolorous medium brown, with most surfaces smooth and shining. The antenna has 12 segments. The dorsum of the head is glossy, the area posterior to the insertions of the antennae have a number of concentric whorls of striae, which extends to the side of the head and posterior to the eye. The top of the mesosoma, especially the pronotum, is mostly smooth and glossy, the sculpture on the dorsum of the pronotum has fine rugae, the side of the pronotum is mostly smooth and shining, but with fine striae, and the sides of the mesosoma have striae or rugae, which become fine rugae on the propodeum. The surfaces that are sculptured are still glossy and shiny. The propodeal spines are small, but developed. The area between the spines and the descending face of the pro-podeum has transverse striae. The side of the petiole is roughly sculptured, with punctures mixed and merging into striae, the top of the node is more finely punctate, with coarse irregular rugae, the side ofthe postpetiole is finely sculptured, with fine punctures, the top has similar sculpture. The petiolar node is rounded as seen in profile.

This species is a member of a group of species (part of the andrei species complex) in which the dorsum of the head is completely smooth and shining, but there are striae or rugae on the sides of the head. The propodeal armature consists of small spines. It could be confused with Temnothorax brevispinosus, but differs in that the hairs on the scape are mostly decumbent (suberect to nearly erect in Temnothorax brevispinosus). The propodeal armature of Temnothorax manni consists of spines, whereas the propodeal armature of Temnothorax brevispinosus is developed into tiny angles, which are little higher than the surrounding surface of the propodeum. It is perhaps most closely related to Temnothorax bristoli. It can be differentiated in that the mesopleuron and sides of the propodeum are covered with coarse rugae. These surfaces are punctate in Temnothorax bristoli. The dorsum of the propodeum of the two species has sculpture similar to the sides. The propodeal spines and shape of the petiole (in profile) are nearly identical. It can be easily separated from the similar Temnothorax punctithorax as the side of the pronotum is predominantly smooth and shining (roughly sculptured in Temnothorax punctithorax)."
