“…Later, Imaizumi (1961) Crocidura watasei is endemic to the Amami and the Okinawa Groups, occurring on 14 islands (Motokawa,199Sb Abe et al, 1994). However, because it's chromosomal number Qn=26, Harada et al,L985) is distinct from that of C. horsfteldii (2n=38, Krishna Rao & Aswathanarayana, 1978), it is obvious that C. watasei is actually a separate species endemic to the central Ryukyus (Motokawa et al, 1996).…”

“…However, we suspect that C. horsfieldii kurodai from Taiwan is also a unique species, which may or may not be closely related to the C. horsfieldii groups, so we will refer to it as C. kurodai. Indeed, the karyotype of C. kurodai is different from that of C. horsfieldii indochinensis (2n = 38 and FN = 48; Rao & Aswathanarayana, 1978) and C. horsfieldii watasei (2n = 26 and FN = 52; Harada et al, 1985). Reumer & Meylan (1986) consider C. horsfieldii watasei a distinct species, C. watasei, based on chromosomal features alone.…”

With 3 plates and 2 figures in the text)We define the species boundaries of white-toothed shrews (genus Crocidura) in Taiwan using karyological and morphological characteristics. Ninety-nine animals were obtained from all over Taiwan at capture rates usually less than 10%. Three species are recognized by distinct cytotypes:Crociduru uttenuata tanakae 2n = 40, FN = 56; Crocidura suaveolens hoslefti 2n = 40, FN = 50; Crocidura kurodai 2n = 40, FN = 54. A suite of six morphological characters diagnose the three species: shape of skull, position of incisive foramina, shape of fourth upper premolar, shape of pinna, tail vibrissae, and foot pads. A species key and notes on the life history of each species are provided. Finally, we discuss chromosomal evolution and biogeography of Crociduru in East and South East Asia.

“…However, Fang et al (1997) re-evaluated C. h. kurodai as a unique species, C. kurodai, on the basis of differences in karyotype and morphology between samples from central Taiwan and south India. Chromosome numbers and the fundamental number of C. kurodai and C. hors®eldii are reported as 40 and 54 (Fang et al, 1997), and 38 and 48 (Rao & Aswathanarayana, 1978), respectively. Meanwhile, samples of tadae have been too few for reasonable analysis.…”

Crocidura tadae was ®rst reported as a new species from Orchid Island by Tokuda & Kano (1936). However, both C. tadae and C. kurodai from Taiwan were considered as subspecies of C. hors®eldii by subsequent researchers. In the present study, the karyotypic and morphological differences among the potential C. tadae specimens from Taiwan main island and two offshore islands (Orchid Island and Green Island) were examined. The results revealed that there is no signi®cant difference in the karyotypes of these shrews but that their karyotype is different from that of other Crocidura species. Therefore, the Tadae's shrew C. tadae Tokuda & Kano, 1936 should be a valid species. Furthermore, morphological variation in 25 external and cranial characters of 106 specimens were analysed using univariate statistics, and eight selected characters were used for multivariate analyses. Univariate statistical comparisons of the three insular samples revealed that shrews of the Green Island population were the largest in most measurements of characters and shrews of the Orchid Island population were the smallest. Multivariate analysis differentiated the Taiwan samples from the other two insular samples. Therefore, three subspecies of C. tadae are recognized: C. t. tadae (Orchid Island); C. t. kurodai (Taiwan) and C. t. lutaoensis subsp. nov (Green Island).

Karyological analysis of the Horsfield's shrew from peninsular India

Abstract: The chromosome complement of the Horsfield's shrew, Crocidura horsfieldi (Soricidae--Insectivora) was studied and the diploid number established to be 2n = 38. Comparisons were made with other species of the genera.
