Little is known about the biology of Temnothorax schoedli.

Identification

Csösz et al. (2015) - A member of the sordidulus species-complex. Temnothorax schoedli is the lightest colored of the species-complex. In addition to color it can be separated safely from other members of the complex by its very restricted geographical occurrence in the southern ranges of Taurus Mountains in Turkey. Temnothorax schoedli can be separated from Temnothorax artvinensis, which in geographical terms is the most closely situated relative of this species, by the coarse dull head sculpture and the very dark brown to black color of the latter and its significantly shorter head. The non-overlapping CL/CWb ratio (see S4 Table) provides a perfect tool to separate of T. schoedli from T. artvinensis at the level of nest sample means.

In its relatively lighter color and occasionally smooth head dorsum this species may superficially resemble species of Temnothorax angustifrons complex. The geographical range of T. angustifrons, Temnothorax lucidus, Temnothorax similis, and Temnothorax subtilis broadly overlap with that of T. schoedli. However, nest samples of T. schoedli can be separated easily from those of these species by non-overlapping ratios (S4 Table): T. schoedli can be separated from T. subtilis by the longer propodeal spines (SPST/CS); from T. similis by PEH/CS and NOH/CS ratios; from T. lucidus by SPBA/CS; and from T. angustifrons by the FRS/CS ratio.
