Mauritius Island (from the Mascarene group, Indian Ocean). At altitudes from 500 to 800 m [1] [2] .
Description
Small ants (length about 3 mm) are brown in color, similar to representatives of the Leptothorax genus, living in tropical forests at heights from 200 to 1755 m. They differ from similar species ( Nesomyrmex flavus , Nesomyrmex madecassus , Nesomyrmex nitidus and others) in a prominent ledge (hump) medium breast, brown, morphometric proportions. 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] [3] . The species was first described in 1946 by the English worldmecologist G. Donistorp under the original name Ireneopone gibber Donisthorpe, 1946 [4] , and its valid status was confirmed during an audit conducted in 2016 by entomologists Sándor Csősz and Brian Lrian Fisher ; Entomology, California Academy of Sciences , San Francisco , California, USA ) based on Mauritius. It is included in the species group Nesomyrmex madecassus , for which the unarmed anterior edge of the pronotum is characteristic (there are no shoulder spines), there are no anterodorsal spines on the petiol nodule; propodeal spines reduced, smoothed sculpture; methanotic groove developed [1] .
