Wu, Yi, Motokawa, Masaharu, Li, Yu-Chun, Harada, Masashi, Chen, Zhong & Lin, Liang-Kong, 2009, Karyology of eight species of bats (Mammalia: Chiroptera) from Hainan Island, China, International Journal of Biological Sciences 5 (7), pp. 659-666 : 663

The karyotype of Pipistrellus abramus

The karyotype of Pipistrellus abramus from Hainan Island was 2n = 26, FN = 44 ( Fig. 5 ), consisting of ten large to medium-sized metacentric or submetacentric pairs and two small acrocentric pairs in autosomes, a medium-sized acrocentric X chromosome, and the smallest acrocentric Y chromosome. The conventionally stained karyotype of P. abramus from Hainan Island does not differ from conspecific populations from the Chinese provinces of Zhejiang, Henan, and Sichuan, Taiwan, Japan, or Korea [ 8, 14, 37 - 43]. Large negative G-band and positive C-band areas were found in the pericentromeric regions of chromosome 1 through 4, 10, 11 and X; and these are considered centromeric constitutive heterochromatin. This characteristic was also reported from Japan and Taiwan [ 38, 41, 42], and any difference in G- and C-banding patterns among populations from Hainan Island, Japan and Taiwan was detected.
