Synonyms

This is a remarkable high-elevation Guatemalan endemic. The notched clypeus is a highly distinctive feature.

Identification

Prebus (2017) - A member of the sallei clade.

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.

Biology

J. Longino, 29 Sep 2015: The species has remained unknown since the collection of the original two series on which the name is based. Bob Anderson just collected a nest series beneath a stone at a site just north of Huehuetenango (La Torre, Aldea Xemal, 15.48368 -91.53455 ±50m, 3791m, 14Jun2015, R. S. Anderson#2015-146X), in a moss-pine-juniper forest. The colony was polygynous, with multiple dealate queens.

Taxonomic Notes

J. Longino, 29 Sep 2015: Temnothorax stollii was described by Forel in 1884, based on a collection of workers and a male. The collection was by Stoll, from the summit of Volcan de Agua, Guatemala. The elevation was reported as 14,000 feet on the label and in the publication, but the peak is actually 12,340 feet (3,760m). Champion later collected a series of workers, males, and queens at the same site, with 13,000 feet on the label. Forel (1899) described the queen from the Champion series.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
