Excluded from the extreme, workerless inquilines. Once this species was included in the extreme, workerless inquilines but now it is considered to be a workerless inquiline without extreme reductions, e.g. no pupoid males but normal ones. The decision to exclude it was made by Edward Osborne Wilson in 1984 in a study of the inquilines in the genus Pheidole Westwood, 1839.

A remark about synonymy.
Tetramorium friedlandi (Creighton, 1934) is now a synonym from Tetramorium atratulum (Schenck, 1852), more precisely an introduced form in North America (see also Schär, Talavera, Espadaler, Rana, Andersen, Cover, Vila, 2018.). This synonymy was given by Creighton, 1950. So, the name is Tetramorium atratulum (Schenck, 1852)...

And then...
…, if you follow the line further that Ward, Brady, Fisher, Schultz, 2015 (“2014”) outlined, the first 10 extreme, workerless inquilines become a few species in the genus Strongylognathus Mayr, 1853.
01) Strongylognathus inquilinum (Ward, Brady, Fisher, Schultz, 2015 (“2014”))
(= Strongylognathus schneideri (Kutter, 1950))
02) Strongylognathus kutteri (Tinaut, 1990)
03) Strongylognathus seiferti (Kiran, Karaman, 2017, in Kiran, Karaman, Lapeva-Gjonova, Aksoy, 2017)
04) Strongylognathus buschingeri (Lapeva-Gjonova, 2017, in Kiran, Karaman, Lapeva-Gjonova, Aksoy, 2017)
05) Strongylognathus albenae (Salata, van Delft, Borowiec, 2023, in Salata, van Delft, van Delft, Georgiadis, Borowiec, 2023)
07) Strongylognathus atratulus (Schenck, 1852)
08) Strongylognathus friedlandi (Creighton, 1934)
09) Strongylognathus microgyna (Santschi, 1918)
10) Strongylognathus parasiticum (Bolton, 1980)
If you followed the systematics of ants in 2014-2015, you noticed that all the species of Teleutomyrmex Kutter, 1950 and Anergates Forel, 1874 became Tetramorium Mayr, 1855. But normally, they should have the name Strongylognathus Mayr, 1853. No, they, Ward, Brady, Fisher, Schultz, 2015 (“2014”), didn't like that! So, until the ICZN would say different, they kept Tetramorium Mayr, 1855.
And now you find under a few species, described in the "normal" genus “Teleutomyrmex Kutter, 1950”, this:
“[Note: Kiran, et al. 2017: 146, retain the paraphyletic genus Teleutomyrmex.]”
But they keep themselves a paraphyletic genus, nl. Tetramorium Mayr, 1855! So it should be Strongylognathus Mayr, 1853...
