摘要

Conventionally and differentially stained karyotypes of the white-tailed mole, Parascaptor leucura, collected in northern and eastern Myanmar, were examined. The diploid number was 2n = 34, which is rare for Asian species of the subfamily Talpinae. The karyotype comprised nine metacentric, four subtelocentric, and three acrocentric pairs and a sex pair. Therefore, the fundamental number of autosomes is Fna = 58. This differs from Fna of the Chinese P. leucura, indicating that chromosome variation may occur in this species. The Y chromosome was clearly identified as a small acrocentric chromosome. The G-band pattern of some middle-size meta-submetacentric chromosomes was identical to those of most species in the subfamilies Talpinae and Scalopinae, indicating the conservative nature of these chromosomes. One of the large metacentric pairs was clearly larger than the remainder of the karyotype complement. This marker chromosome is thought to be identical to those of Scalopinae species, although they belong to a different subfamily. P. leucura appears to have a unique karyotype among Asian species of talpine mole.
