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.

  • coloratus. Lasius niger st. coloratus Santschi, 1937h: 387 (w.q.) TAIWAN. Combination in L. (Lasius): Wilson, 1955a: 60. Junior synonym of niger: Wilson, 1955a: 60. Revived from synonymy and raised to species: Seifert, 1992b: 44.

Seifert (2020) - Rather large (CS 985 µm). Head and scape length indices rather large (CL/CW900 1.083, SL/CS900 1.029). Postocular and torulo-clypeal distances large (PoOc/CL900 0.250, dClAn900 5.23); terminal segment of maxillary palp long (MP6/CS900 0.209). Number of mandibular dents medium (MaDe900 8.28). Pubescence on clypeus moderately dense (sqPDCL900 4.69); frontal pubescence of medium length (PLF900 29.5). Pubescence surface on body and appendages rough. Setae of medium length and numerous (PnHL/CS900 0.156, GuHL/CS900 0.102, nOcc900 14.6, nGen900 5.5, nGu900 6.2, nSc900 24.6, nHT900 22.0). Sculpture on metapleuron, lower propodeum and often pronotum differing from the condition in species related to Lasius niger or Lasius japonicus in having regular, slightly curved, dense longitudinal carinulae and delicate microstructures within the meshes of the microreticulum. This produces a matt overall surface appearance at lower magnifications. Coloration: more or less bicolored. The lighter forms have the mesosoma pale yellowish-reddish brown, the dorsum of head slightly and the gaster notably darker. The darker forms have the mesosoma medium reddish brown, the dorsum of head dark brown with a reddish tinge and the gaster blackish brown.

See table 10 in Seifert 2020 for additional morphometrics. The abbreviated names of various quantitative data shown above are defined here: Seifert 2020 Lasius characters.
