Outline of Final Research Achievements |
Field surveys conducted in tropical Asia revealed three subterranean Crematogaster species. I described one Vietnamese taxa as new species. Those subterranean species had reduced compound eyes with 10 ommatidia to 5-6 ommatidia. Cladistic analysis using morphological characters revealed that subterranean form evolved independently in different lineages. The basal margin of mandibles in subterranean species is different from normal ground-dwelling species, suggesting specialized predator. Morphological specializations such as developed body hairs, relatively large spiracles, and light yellow body color were found in those species.
