Synonyms

Lasius is one of the most prominent and familiar of the Holarctic ant genera. From the time of Reaumur in the eighteenth century (Wheeler, 1926), European and North American entomologists have focused attention on it in countless general biological and taxonomic investigations which are today part of the classical foundation of myrmecology. It is probably best known for its conspicuous nuptial flights, its habit of tending and transporting homopterous insects, and the temporary parasitic behavior of some of its species. It has also attracted much attention as one of the several ant genera which have persisted in Europe and North America since early Tertiary times with only a small amount of visible evolutionary change. (Wilson 1955)

Identification

The morphological distinctions between Lasuis and Acanthomyops have always been unambiguous but it has taken a recent molecular phylogenetic analysis (Janda et al. 2004) to settle whether or not these two groups represent two distinctive genera. The latter is well accepted today as a synonym of Lasius. It remains convenient for identification purposes to distinguish Acanthomyops as a distinctive species group within Lasius.

Nearctic species of Lasius with long maxillary palpi, those that were once thought to be distinctive from Acanthomyops, can be determined to species using this key by Wilson (1955) :

Wing (1968) provides the following in his revision of the Neartic Acanthomyops: Acanthomyops has short, 3-segmented maxillary palpi, while those of Lasius are 6-segmented and long. Another attribute of Acanthomyops that serves as a convenient diagnostic character for field collectors using a mouth-type aspirator is the presence of a characteristic odor produced by the mandibular glands of disturbed workers. This odor, a defense mechanism, is like that of oil of citronella or lemon verbena. As sensed by a collector with normal olfactory powers the odor is pronounced. A few species of Lasius possess a similar odor, but it is sensed, at most, as quite weak. Lasius umbratus probably has the strongest odor of any species of Lasius, yet it is decidedly weaker than that of all species of Acanthomyops I have collected.

There is also a somewhat outdated (1955) and restricted (no Nearctic Acanthomyops queens and males):

Distribution

Lasius occupies a purely Holarctic range. Northward it reaches northern Scandinavia, the Baikal region of Siberia, Kamchatka, southeastern Alaska, and southern Labrador. Southward it reaches Madeira, North Africa, northern Iraq, the southern Himalayas, the mountains of Formosa, the mountains of central Mexico, and northern Florida. Where it comes closest geographically to tropical faunas, as in southeastern Asia, it still retains its north-temperate character, i.e., limited to temperate vegetation at higher elevations and there associated chiefly with typically Holarctie ant genera.

Biology

Within this range it is among the most abundant of all insect genera. In Europe the two species Lasius niger and Lasius flavus are often the overriding dominants of the ant fauna in local situations and under a variety of ecological conditions. In the eastern United States neoniger mounts such dense populations in open fields and lawns that W. M. Wheeler was once moved (1905) to suggest that it might be the most abundant insect in North America. Such a contention would probably be an exaggeration with respect to all insects, of course, yet there is no denying neoniger its importance as a major faunal influent within its range and favored habitat.

Lasius is also remarkable - perhaps unique - among animal groups thus far monographed, in its great abundance, ubiquity, and conspicuousness, and the consequent ease with which it can be found in the field. Anywhere in the northern United States, in practically all but desert and semidesert conditions, it is possible for an investigator to walk onto nearly any plot of ground and within a matter of minutes find nests of one or more species. (Wilson 1955)

Nomenclature

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

  • LASIUS [Formicinae: Lasiini]

    • [Lasius Jurine, 1801: 164 (Apidae), resurrected by Morice & Durrant, 1915: 421, suppressed by Act of Commission.]
    • Lasius junior synonym of Acanthomyops: Forel, 1916: 460; Donisthorpe, 1916c: 276; Morice & Durrant, 1917: 442. Donisthorpe, 1927b: 206; Donisthorpe, 1937b: 132; Donisthorpe, 1943f: 655; Donisthorpe, 1946g: 91.
    • Lasius junior synonym of Formicina: Emery, 1916a: 61; Bondroit, 1918: 19.
    • Lasius as genus: Wheeler, W.M. 1916k: 172; Emery, 1925b: 226; Wilson, 1955a: 11.
    • Lasius senior synonym of Donisthorpea: Wheeler, W.M. 1916k: 172; Emery, 1925b: 226; Wilson, 1955a: 11.
    • Lasius senior synonym of †Tylolasius: Hong, Wu & Ren, 2001: 348.
  • ACANTHOMYOPS [junior synonym of Lasius]
    • Acanthomyops Mayr, 1862: 699. Type-species: Formica clavigera, by monotypy.
    • Acanthomyops junior synonym of Lasius: Mayr, 1866b: 888.
    • Acanthomyops revived from synonymy as subgenus of Lasius: Emery, 1893i: 642.
    • Acanthomyops incorrectly as senior synonym of Lasius: Forel, 1916: 460; Donisthorpe, 1916c: 276.
    • Acanthomyops subgenus of Formicina: Emery, 1916a: 11; Forel, 1917: 249.
    • Acanthomyops subgenus of Lasius: Wheeler, W.M. 1916k: 172; Wheeler, W.M. 1922a: 698; Emery, 1925b: 236.
    • Acanthomyops revived status as genus: Creighton, 1950a: 426.
    • Acanthomyops subgenus of Lasius: Ward, 2005: 13.
    • Acanthomyops subgenus of Lasius: Boudinot et al., 2022: 135.
  • AUSTROLASIUS [junior synonym of Lasius]
    • Austrolasius Faber, 1967: 74 [as subgenus of Lasius]. Type-species: Lasius carniolicus, by original designation.
    • Austrolasius subgenus of Lasius: Boudinot et al., 2022: 135.

  • CHTHONOLASIUS [junior synonym of Lasius]
    • Chtonolasius Ruzsky, 1912: 630 [as subgenus of Lasius]. Type-species: Formica umbrata, by subsequent designation of Emery, 1925b: 232.
    • [Chtonolasius also described as new by Ruzsky, 1914a: 59. The claim by some authors (e.g. Emery, 1916a: 11; Donisthorpe, 1941f: 37; Donisthorpe, 1943f: 633) that Ruzsky nominated Lasius flavus as type-species is incorrect. Ruzsky (1912: 630) included those species "with the appearance of the yellow Lasius (Las. flavus D.G.) and its closely related species, and races (Las. carniolicus, Las. umbratus, Las. myops, Las. mixtus)". This is not a direct nomination of a type-species, nor is De Geer (D.G.) the author of flavus: Bolton, 1995b: 24.]

    • Chthonolasius subgenus of Lasius: Boudinot et al., 2022: 135.
  • DENDROLASIUS [junior synonym of Lasius]
    • Dendrolasius Ruzsky, 1912: 630 [as subgenus of Lasius]. Type-species: Formica fuliginosa, by monotypy.
