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.



(Ito 1997) - Ergatoid queens of L. myops are exceptionally large in body size (head width 1.18 mm) relative to workers (head width 0.75 mm); other Oriental species show similar head widths between castes. L. myops queens have 32-34 ovarioles per ovary while workers have 3 ovarioles per ovary. In contrast, other species have same ovariole numbers between castes.
