Specimen Labels

There are more than a dozen rainforest collections of this ant, with a single dry evergreen forest record; all from litter samples.

Identification

Bolton (1977) - Very closely related to Tetramorium eleates, separated only tenuously by slight colour differences and the fact that in eleates the petiole dorsum tends to be sculptured over its entire surface whilst in flavipes there is an un sculptured median strip. These are very weak characters for separating two species of Tetramorium and I feel that further collections may show that these are but expressions of the same species.

Nomenclature

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

  • flavipes. Tetramorium (Xiphomyrmex) flavipes Emery, 1893f: 247 (footnote) (w.) THAILAND. See also: Bolton, 1977: 81.

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

Description

Worker

Bolton (1977) - TL 3.2-3.6, HL 0.76-0.80, HW 0.70-0.76, CI 90-95, SL 0.53-0.62, SI 77-82, PW 0.58-0.62, AL 0.90-0.98 (12 measured).

Mandibles striate. Frontal carinae strong, reaching back almost to the occipital margin, where they merge with the sculpture. Occipital margin more or less straight to feebly concave in full-face view, the sides weakly convex. Antennal scapes moderate, SI as above. Alitrunk in dorsal view with sharply angled pronotal corners giving the alitrunk a 'square-shouldered' appearance. Propodeal spines elongate, narrow and acute; metapleural lobes elongate-triangular and sharp. Petiole node in profile slightly higher than long, with more or less parallel anterior and posterior faces and a convex dorsum. In dorsal view the petiole node is slightly longer than broad and a little broader behind than in front. Dorsal surfaces of head and alitrunk finely reticulate-rugulose, the sides and dorsum of the petiole rugulose but mediodorsally there is a narrow unsculptured longitudinal strip. Post petiole either completely smooth or at most with only very faint traces of sculpture laterally. All dorsal surfaces of head and body with erect hairs which are quite stout and tend to be blunted apically. Middle and hind tibiae without such hairs, with only short decumbent hairs. Colour black or blackish brown with pale yellow legs.

Type Material

Bolton (1977) - Holotype worker, Thailand (E. Simon?) (Probably in Museo Civico di Storia Naturale, Genoa).
