Abstract
A survey of chromosome polymorphism was made in populations of Pheidole nodus (Hymenoptera, Formicidae). A total of 1,666 males were collected from 11 localities in Japn. Four polymorphic karyotypes were observed: (1) n = 17 with 4 metacentrics (abbreviated as 4M), (2) n = 18(3M), (3) n = 19(2M) and (4) n = 20(1M). These differences are due to the Robertsonian type rearrangement. The karyotype 18(3M) is found in all the populations examined, but the others are more or less localized in their distribution. The 17(4M) appears mainly in Shikoku and the northern Kyushu populations, 19(2M) along the Pacific coast of Honshu, Shikoku and Kyushu, and 20(1M) in the eastern part of Honshu and Shikoku. This distribution pattern indicates that 18(3M) is the oldest, 19(2M) and 20(1M) are derived from 18(3M) by centric fission, and 17(4M) by centric fusion. The most probable mechanism of karyotype evolution in this species is considered to be the centric fission.
