Nomenclature

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

  • infraspinosum. Tetramorium infraspinosum Karavaiev, 1935a: 104 (w.) VIETNAM. See also: Bolton, 1977: 132.

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) - Abstracted from the original description: TL about 2.0. Head 1.16 times longer than broad (i.e. CI c. 86). Anterior clypeal margin entire. Occipital margin feebly concave, sides of head parallel, occipital corners moderately rounded. Frontal carinae directed to occipital corners [presumably reaching beyond level of eyes]. Scape failing to reach occiput by 2 x apical width. Eyes moderately large, in front of midlength of head. Propodeal spines triangular, acute, somewhat elevated; in dorsal view about as long as the distance separating them. Metapleural lobes twice as long as spines, triangular and acute. Petiole in profile with node rectangular, in dorsal view the node longer than broad. Postpetiole about 1.5 x broader than petiole in dorsal view. Head and alitrunk sharply and extensively reticulate-rugose. Dorsum of head longitudinally rugose with about 10-11 components, the spaces between them punctate. Alitrunk reticulate-rugose dorsally, punctate laterally. Petiole punctate with some weak rugae, postpetiole coarsely and irregularly longitudinally rugose. Gaster unsculptured. Erect hairs short, moderately developed. Yellow-rust coloured, gaster and appendages paler, yellowish.

Type Material

Holotype worker, Vietnam (= Cochinchine): Cauda, 10.x.1930, no. 5788 (K. Davydov) (location of type not known). I have not been able to find the holotype and only known worker of this species.
