Temnothorax stollii

Known only from type specimens.

Identification
Mackay (2000) " Workers of this species can be recognized by a 12 segmented antenna, by the offset basalmost tooth, the coarse carinae on the clypeus, which terminate as teeth on the anterior border of the clypeus, which give the anterior edge a crenulate appearance. The malar area has numerous coarse rugae, the area posterior to the insertions of the antennae is without concentric. curved striae, as are found in most species. The scape extends to the occipital corner; the dorsum of the head is nearly smooth, interspersed with piligerous punctures, the pronotum is finely striate, the remainder of the mesosoma is rugose. the propodeal spines are well developed and the node of the petiole is rounded in profile. The mesosoma is slightly depressed at the mesopropodeal suture. The male is unusual in that the scape extends well past the occipital corner and the petiole and postpetiole appear "swollen" and thickened.

This species is included in the nitens species complex. although it does not fit well and probably deserves to belong to its own complex. The carinae on the clypeus are similar to those of the nitens complex. except they terminate in teeth on the anterior border of the clypeus. The petiolar node is relatively sharp. and is slightly carinate on each side, but it is not as sharp as it is in other species in the complex. The scapes of both the worker and male are exceptionally long, which would separate it from other members of the subgenus. Thus, these unusual characters, and the offset basal tooth, would separate this species from all others in the subgenus. It is also the only species known from Guatemala."
