I don't know too much about Asian ant species, but shouldn't Asia be further devided since it's so big? Maybe like Eastern Asia (China, Korea's, Mongolia, Taiwan, and Japan), Southern Asia (Bangladesh, Bhutan, India, Pakistan, Nepal, Sri Lanka, Afghanistan, and the Maldives), South-East Asia (Brunei, Myanmar, Cambodia, Timor-Leste, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand and Vietnam), Central Asia (Kazakhstan, Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan), West Asia (Armenia, Azerbaijan, Bahrain, Cyprus, Georgia, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Palestine, Qatar, Saudi Arabia, Syria, Turkey, United Arab Emirates, and Yemen), and then you have Russia. It's a pretty long list, so I guess you can mash together some of them if they have similar species.
