Identification

Csösz et al. (2015) - A member of the angustifrons species-complex. This species differs from members of other species complexes treated in this revision by its smooth and shiny head dorsum and the relatively short propodeal spines. This character combination is shared with other members of the species complex: Temnothorax angustifrons, Temnothorax subtilis and Temnothorax similis. Nest samples of Temnothorax lucidus can be separated from those of T. angustifrons by their shorter scape (SL/CS) and wider frons (FRS/CS). Their simple ratio (FRS/SL) provides an excellent tool to separate workers with less than 5% of error rate. Ratios of NOH/CS and PEH/CS help to distinguish this species from T. similis on the level of nest samples. A discriminant (D4) function, including discriminant scores for separating single individuals with acceptably low error rate, is given in the differential diagnosis of the latter.

The spine length ratio (SPST/CS) provides a good quick character to separate nest samples of T. lucidus from those of T. subtilis, but in single workers this character may broadly overlap between the two species. A discriminant function with reduced character number (D4) yields 98.6% classification success rate.

Temnothorax lucidus can be easily separated from two additional species of the parvulus species-complex that occur in Crete, Temnothorax ariadnae and Temnothorax helenae, based on shiny surface of the head dorsum. In exceptional cases, or if dust obstructs a clear view of the surface sculpture, nest samples of T. lucidus can be separated from T. ariadnae by non-overlapping ranges of body ratios (NodL/CS and NOL/CS). Simple ratios do not help to distinguish T. lucidus and T. helenae, hence a simplified discriminant function (D3 = -0.0807_POC +0.0896_SL -0.0578_SPTI -11.284) is recommended to separate nest samples of these specie. The same function yields 97.9% classification success rate between single individuals of these species.
