Description
Small ants (about 3 mm long) yellowish in color (black males), similar to representatives of the Leptothorax genus, living in tropical forests at altitudes of about 1100 m. They differ from similar species in long curved spines of the thorax, smooth (almost shiny) dorsal surface of the head, angular humeral edges of pronotum, long scape of antenna. Antennae 12-segmented with a mace of 3 segments. 5-pronged mandibles . Propodeum angular with two spines. 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 [1] [2] . The species was first described in 2016 by American entomologists Sándor Csősz and Brian L. Fisher ; Entomology, California Academy of Sciences , San Francisco , California, USA ) based on materials from Madagascar. It is included in the species group Nesomyrmex sikorai , which is characterized by the absence of spines on the nodule petiol, the presence of spines on the posterior thorax and methanotic groove [1] .
