Csösz, Radchenko and Schulz (2007) - Workers of T. sulcinode can be separated from related species (except for Tetramorium annectens) by well developed psammophore, relatively large eyes. The most distinctive features to separate T. sulcinode from T. annectens, is the PEW/PPW index and the sculpture of petiolar node: semi-circular rugulose in T. sulcinode, reticulate in T. annectens. Workers of T. sulcinode mostly resemble Tetramorium anatolicum by the fine, parallel body sculpture and the scape characters. These two species can also be separated by the absence/presence of the psammophore and by the non-overlapping relative size of the eyes.
Gynes of T. sulcinode are distinguishable by the well developed psammophore, short and smooth scape without a dorsal carina basally, wide scutum and relatively narrow petiole and postpetiole. Between T. sulcinode and T. annectens the relative petiole width gives separation.

Lectotype worker and Paralectotype workers. The syntype series of Tetramorium caespitum var. sulcinode Santschi, 1927 consists of six workers on two pins, Naturhistorisches Museum, Basel. One pin with four workers and a second pin with two workers. In order to prevent further nomenclatural problems it is necessary to designate the lectotype of T. sulcinode.
From the first pin with four workers: Only one worker of the investigated type material is nearly intact, hence we designate this specimen, positioned on the distal end of the upper card, as the lectotype. The right antenna, the left funiculus and the right foreleg are missing. Lectotype is labeled as: [label with Latin letters] “Ssemiretschie 14/vii.24”, “Ssukuluk, westlich”, “von Pithpek, NB.ii”, “N. Kusnetzow” Type. Paralectotype worker on the same pin are positioned on the distal end of the lower card. Its head is missing, other parts are intact and have other features corresponding to the species characteristics. Two erroneously designated syntype specimens (D(4) =-4.074, p< 0.001, and =-1.571, p< 0.01 respectively) on that pin are in fact T. caespitum indocile; these are positioned on the proximal end of both, upper and lower, cards.
We designated one worker from the second pin as a paralectotype of T. sulcinode, the other worker cannot be determined correctly due to its very poor condition. The details of this second pin: two workers, collected at the same locality: [label with Cyrillic letters] ìSsemiretschie. Ssukulukî, 14-vii-1924. “N. Kusnetzov”. This locality (Ssemiretschie, Ssuskuluk; Pishpek, leg. Kusnetzov) is mentioned as the type locality of T. caespitum var. sulcinode in the original description (Santschi 1927: 53, 54).
