Rhinolophus sinicus, K. Andersen, 1905

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 : 660

The karyotype of R. sinicus

was 2n = 36, FN = 60 ( Fig. 3 ), consisting of 13 large-to-small metacentric or submetacentric pairs and four medium-sized to small acrocentric pairs of autosomes, a medium-sized subtelocentric X chromosome, and a small subtelocentric Y chromosome. This species had a prominent secondary constriction involving one pair of medium-sized acrocentric chromosomes. The karyotype of R. sinicus from Hainan Island (2n = 36, FN = 60) does not differ from conspecific populations in the Chinese provinces of Anhui [ 6] (reported as R. rouxii sinicus ), Sichuan [ 14], and Guangdong [ 15] in conventional karyotype and that from "south-western China" also in G-banding pattern [ 17], but does differ from the 2n = 56, FN = 60 karyotype of R. rouxii reported from India and Sri Lanka [ 31]. These karyological differences between R. sinicus and R. rouxii support the view that these two taxonomically confused taxa both represent distinct species, as previously proposed [ 14, 15, 26].
