Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • CHTHONOLASIUS [subgenus 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 justified emendation of spelling: Wheeler, W.M. 1916k: 170.
    • Chthonolasius junior synonym of Formicina: Wheeler, W.M. 1916k: 172; Emery, 1916a: 11.
    • Chthonolasius subgenus of Acanthomyops: Donisthorpe, 1927b: 254.
    • Chthonolasius subgenus of Lasius: Wheeler, W.M. 1922a: 698; Emery, 1925b: 231; Wilson, 1955a: 13.
