Small myrmycin ants (length about 3 mm), brown. It differs from closely related species in smaller body sizes and a high nodule of petiol. Antenna with mace of 3 segments, short scapus . The stalk between the breast and the abdomen consists of two segments: the petiolus and postpetiolus (the latter is clearly separated from the abdomen), the sting is developed. Workers' head index (CI, head-to-length ratio × 100): 97-102. The length of the head of the workers is 0.66-0.75 mm, the length of the scape is 0.45-0.49 mm, the width of the head is 0.67-0.76 mm. Worker's scapus index (SI, ratio of scapus length to head width × 100): 64–69. Petiolus, postpetiolus and abdomen are smooth and shiny [1] .
The species T. plesiarum was first described in 1979 by the English worldmecologist Barry Bolton ( British Museum Natural History , London ) [2] , and its valid status was confirmed in 2014 by the American worldmecologists Francisco Hita Garcia and Brian Fisher ( Brian L. Fisher ; Entomology, California Academy of Sciences , San Francisco , California , USA ) together with the taxon T. naganum , T. cognatum and T. proximum . The taxon Tetramorium plesiarum is included in the species group T. plesiarum species group of the genus Tetramorium (together with T. bressleri , T. hobbit , T. gollum and T. mars ). It is similar to the species T. bressleri , T. hobbit , T. gollum and T. mars [1] [3] [4] .
