Bolton (1979) - TL 2.4-2.7, HL 0.58-0.64, HW 0.49-0.54, CI 81-85, SL 0.38-0.42, SI 77-80, PW 0.34-0.38, AL 0.68-0.74 (8 measured).
With the general characters of the complex and of the bicarinatum-group to which it belongs, but with additional characters as follows. Frontal carinae less strongly developed than in Tetramorium adelphon or Tetramorium kydelphon, extending back beyond level of eye but weak, scarcely stronger than other cephalic rugulae. Maximum diameter of eye 0'12-0'14, about 0·25-0'27 x HW. Petiole node in dorsal view as broad or slightly broader than long. Dorsum of head irregularly longitudinally rugulose, with a reticulum occipitally. Dorsal alitrunk reticulate-rugulose but without a raised transverse carina at the promesonotal junction. Petiole dorsum with sparse rugulae, postpetiole dorsally with fine superficial punctulation, at most with only one or two very feeble longitudinal marks. Pilosity on dorsal surfaces of head and body much denser than in adelphon or kydelphon, the individual hairs finer and more flexuous than in those species. Colour pale yellow.
