![]() (2019) examined winter foraging activity in western Japan. Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species. Relative abundance based on number of AntMaps records per species (this species within the purple bar). In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species. Number of countries occupied by this species based on AntWiki Regional Taxon Lists. Palaearctic Region: Japan ( type locality), Republic of Korea.Ĭheck data from AntWeb Countries Occupied Oriental Region: Bangladesh, India, Sri Lanka, Taiwan, Thailand, Vietnam. Latitudinal Range: 37.283506° to 14.116667°.ĭistribution based on Regional Taxon Lists Widely distributed in the Manchurian subregion and Oriental region. tumida has a very large lobate subpetiolar process. At present it is impossible to separate the two by minor’s morphology. Pheidole noda is distinguished among Indo-Chinese species by the combination of the following characteristics: in the major head in full-face view relatively broadly and deeply concave posteriorly in the major dorsum of head sparsely bearing standing hairs which are much longer and distinctly thicker than background hairs in the major posterior part of vertex and dorsal and lateral faces of vertexal lobe rugoso-reticulate in the major subpetiolar process absent or at most present as a low carina in the major and minor postpetiole massive. ![]() ![]() Major and minor workers of Pheidole nodus from Taipei, Taiwan. This is one of the most common ants in southwestern Japan. Imai & Kubota (1972) reported chromosomal variation. The presence of hostile ants does not influence soldier production (Nakao, 1973). Soldiers dissect large food items and defend the nest and surrounds (Yano & Yamane, 1990). (Eguchi 2008) Colonies are large, comprising up to ca 3,000 individuals (Yano, pers. Vietnam this species is one of the prey of Aenictus dentatus. According to Eguchi (2004b) workers gather seeds of sesame and amaranthus put on the ground in southern Japan. This species occurs from open lands to relatively developed forests, and nests in the soil, under shelters on the ground, and in rotting logs.
