Identification

Salata and Borowiec (2017) - Tetramorium bellerophoni in all castes is extremely similar to Tetramorium galaticum. The best distinguishing characters are found in males. However, in examining a group of workers from a nest series the following differences can be observed (characters for T. galaticum in parentheses): head in workers of T. bellerophoni is striated on almost the whole surface, also on the postocular area, only between frontal rugose area and rugosities along ocular area on each side with a small area of diffused rugosities (usually on sides of frons and in postocular area with large smooth patches), propodeal spines of T. bellerophoni are longer and spiniform (shorter and triangular). Head in T. bellerophoni is slightly stouter than in T. galaticum (CL/CW ratio 1.036 vs. 1.051). Gynes of T. bellerophoni have a slimmer head (CW/CL ratio 1.078 vs. 1.091). Males of T. bellerophoni differ in the head less regularly rounded behind eyes, slightly trapezoidal (regularly rounded), clypeus with circular rugosities or at least strongly converging (parallel rugosities at most with only two medial ridges partly convergent), frons microreticulate, dull or with only narrow smooth area (partly smooth and shiny), area between eye and ocelli with high oblique rugosities (partly without rugosities only with dull microretoculation), male genitalia in profile more deeply constricted before apex with slightly longer and sharper apical angle and almost twice as short apical setae (less constricted before apex with slightly shorter and less sharp apical angle and almost twice longer apical setae).

Workers of Tetramorium kephalosi and Tetramorium hippocratis differ in darker body, brown to black (in T. bellerophoni yellow), in nests of T. kephalosi most workers have a head with distinct smooth areas laterally to frons and in the postocular area (in T. bellerophoni head is mostly striate with very small smooth areas). Gynes of T. kephalosi and T. hippocratis differ in darker body colour, brown to black (yellow to yellowish-brown in T. bellerophoni) and smaller size with ML always below 1.96 and MW below 1.22 (in T. bellerophoni above 2.0 and 1.3 respectively). Scutum in gynes of T. kephalosi are usually more distinctly striated than in both relatives. Males of T. kephalosi and T. hippocratis differ in top of inner margin of paramere before apical denticle with narrow lamella (without lamella in T. bellerophoni), male of T. bellerophoni differs also in clypeus with circular striation (parallel in both T. kephalosi and T. hippocratis).
