12. Temnothorax gracilicornis (Emery) ^HNS

(5, w q; males eclosed in the laboratory). Three colonies from this Canarian endemic were collected: two were nesting under mosses on a stone; the third was nesting under a small stone. The morphology and coloration of workers and queens fits the description of L. gracilicornis ^HNS, not of the darker and shinier var. nivarianus ^HNS Santschi, that Wellenius (1955) collected at Frontera. As I have not seen type material of both taxa and samples from Tenerife show varying coloration from yellow to brownish, thus including both names and body surface shininess, I refer the samples of El Hierro to the nominal species. This is not a formal proposal of synonymy.
