Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • deletus. †Technomyrmex deletus Emery, 1891a: 153, pl. 3, figs. 26-28 (w.) SICILIAN AMBER (Oligocene). See also: Bolton, 2007a: 122.

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

Bolton (2007) - This fossil in amber is almost certainly correctly placed in Technomyrmex . It is badly damaged and the abdomen is deformed and ruptured. While this has occluded the characteristic external abdominal characters of the genus it has fortunately exposed the proventriculus to view. In Technomyrmex the cupola of the proventriculus is sculptured (Forel, 1878; Emery, 1888; Eisner, 1957) and the presence of such sculpture appears to be a unique character of the genus. Emery ~ 1891) points out that such sculpture is present in Technomyrmex deletus and from Emery's original description and figures deletus may possibly belong to the Technomyrmex albipes group.
