Cuticular hydrocarbons and morphological features were compared among 80 Formica japonica colonies collected in Japan. Although a few morphological differences were found in workers among the colonies, four different types of cuticular hydrocarbon composition were observed. This was supported by a principal component analysis. We further compared the cuticular hydrocarbons among a total of approximately 400 F. japonica colonies, and categorized the hydrocarbon components into four types based on the result of discriminant analyses for the first 80 colonies. Type 1 was observed in colonies mainly collected in southern Honshu, Shikoku, and Kyushu. Types 2, 3, and 4 were from colonies with primary collections in Southern Honshu, central and Pacific coast northern Honshu, and the Sea of Japan coasts of northern Honshu and Hokkaido, respectively. The occurrence of four distinct types of CHC composition suggests that the colonies that produce them are separate species.
对在日本采集的80个日本蚁群的表皮碳氢化合物和形态特征进行了比较。虽然在蚁群中的工蚁之间发现了一些形态差异，但观察到了四种不同类型的表皮碳氢化合物组成。主成分分析支持了这一点。我们进一步比较了总共约400个日本蚁群的表皮碳氢化合物，并根据对前80个蚁群的判别分析结果将碳氢化合物成分分为四种类型。第1型主要在本州南部、四国和九州采集的蚁群中观察到。第2型、第3型和第4型分别来自主要在本州南部、本州中部和太平洋沿岸北部以及本州北部和北海道的日本海沿岸采集的蚁群。四种不同类型的CHC组成的出现表明产生它们的蚁群是不同的物种。
