synonymy by Bolton (1976: 350).

Mayr's (1870b) description is at . Viehmeyer's (1916a) illustrated note and description of the queen is at . Bolton's (1976) modern description is at ; the separation in his Oriental key is at .

Pantropical tramp species; TL 2.2-3.0 mm. Apart from Tunisia (Emery, 1891b: 4, Triglyphothrix obesus André race striatidens, Tozzer), Bolton gave no records from Africa. Emery (1891b: 4, with a footnote placing the species in the new Forel genus Triglyphothrix) noted M. André had written to him that he had received a specimen from Sierra Leone, but there seems to be no other record of this. André (1890) described species from Sierra Leone but included no Tetramorium. He (André, 1892a) described Triglyphothrix gabonensis from Gabon and commented on the Forel genus definition but mentioned no other genus members from Africa.
