| Formica subnitens|
This species nests in thatched mounds, occasionally under stones or logs, usually with some surrounding thatch. They are occasionally found in earthen domes (Cole 1954, Mackay and Mackay 2002)
The middle and hind tibiae of this species have erect hairs in two rows (usually fewer than ten hairs in both rows combined), but do not have erect hairs scattered over the remainder of the surface. The erect hairs extend over nearly the entire length of the tibia. The gaster has few erect hairs on the first tergum (fewer than 10, excluding those along posterior edge of tergum). This latter characteristic separates it from the closely related Formica ravida which has more than 10 hairs on the same surface. The clypeus, cheeks and malar area are often shiny.

In New Mexico (Mackay and Mackay 2002) - Grasslands to pinyon cedar forests, willows, and cedars.
Nevada, Wheeler and Wheeler (1986) - This species seems to make little use of thatch. The mounds were usually of soil and detritus. F. subnitens is widely scattered in the northern half of the state; 4,600-10,500 ft. We have 9 records from 9 localities, 2 of which were in the Cool Desert and 2 in the Coniferous Forest Biome. Three nests were described: (1) a dome 48 cm in diameter composed of soil and gravel with only a little plant debris; (2) under many stones; (3) messy pile of thatch 28 by 53 cm piled against a stone.
Nest site selected in open areas devoid of cover. Nest begun under stone or by excavation in the soil. Little or no use made of thatching. The finished nest without any superstructure or with a thin disc of thatching spread around the opening (Creighton, 1940).
