Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Biology

Nevada, Wheeler and Wheeler (1986) - Our 8 records from 5 localities are all from the southern part of the state and all in the Pinyon-Juniper Biome. One nest was in the ends of a rotten log (8 cm in diameter) lying on the ground, 3 were under stones, and I was in the slightly decayed buried portion of a log 15 cm in diameter. We noted that the workers were fast and aggressive, that the bite was annoying and that a populous colony produced an invisible cloud of formic acid over a disturbed nest.

Other Ants

Nests of this species occasionally host Temnothorax andrei, although the nature of the relationship is unknown (Mann, 1911).

This species is a host for the ant Polyergus vinosus (a slave maker) (Trager, 2013; de la Mora et al., 2021).

Nomenclature

The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

moki. Formica moki Wheeler, W.M. 1906d: 343 (w.) U.S.A. Cole, 1966: 25 (m.). Combination in F. (Neoformica): Wheeler, W.M. 1913f: 558. Junior synonym of occidua: Francoeur, 1973: 254. [Note that moki has seniority over occidua and hence is the valid name; see Smith, D.R. 1979: 1453.] See also: Smith, M.R. 1939f: 582.
occidua. Formica rufibarbis var. occidua Wheeler, W.M. 1913f: 517 (w.q.) U.S.A. [F. rufibarbis var. occidua Wheeler, W.M. 1912c: 90. Nomen nudum.] Subspecies of rufibarbis: Creighton, 1950a: 539. Raised to species and stated as senior synonym of moki: Francoeur, 1973: 254 [the latter has priority and hence is the valid name: Smith, D.R. 1979: 1453].

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
