Nomenclature
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.
- †nemorivagus. †Lasius nemorivagus Wheeler, W.M. 1915h: 123 (q.) BALTIC AMBER (Eocene). See also: Wilson, 1955a: 150; Dlussky, 2011: 216.
Description
Queen
Wilson (1955) - According to Wheeler, maxillary palps typical for the subgenus Lasius, but head broader than thorax, a Chthonolasius: and Dendrolasius character. Funicular joints II-VI broader than long, VII-X as broad as long. Body more thickset, appendages stouter than in Lasius schiefferdeckeri. Size small, total length 6 mm., the lower limit later given by Wheeler (1917a) for the queen caste of "neoniger" (Lasius pallitarsis, Lasius niger, and Lasius neoniger). Body with sparse erect hairs; appendages presumably bare.
Type Material
Wilson (1955) - HOLOTYPE. The single type specimen was probably lost with the rest of the Konigsberg Geological Institute Collection during the Second World War.
