| 中文摘要: |
| 2021年9月13日在浙江德清莫干山（30°36′27″ N，119°51′39″ E，海拔601 m）采集到1只刺猬标本。该标本耳较短，不超过周围棘刺长。体背棘刺短细，几无全白色棘刺，大部分棘刺从基部至刺尖分为4段：第1段白色，长度占棘刺长2/3以上；第2段黑色或深褐色，约3 ~ 5 mm；第3段白色，约1 ~ 3 mm；第4段，即棘刺尖端，黑色或深褐色。头骨吻部较短，鼻骨狭长；整个额部较为平直；矢状脊不发达，但明显可见；人字脊发达。这些特征与侯氏猬（Mesechinus hughi）的鉴别特征基本一致。基于Cyt b 全序列构建的最大似然树显示，该标本与安徽的侯氏猬聚为一支（支持率100%），该支又与陕西的侯氏猬聚为一支（支持率97%），并构成单系群。该标本Cyt b全序列与安徽的侯氏猬遗传距离为0.35%，与陕西的侯氏猬遗传距离为4.92% ~ 5.27%。基于以上结果，确定该标本为侯氏猬。这是林猬属侯氏猬在浙江省的首次记录，也是继安徽发现侯氏猬以来，再次在长江以南发现侯氏猬的新分布点。根据已获取的信息，浙江的侯氏猬在浙西丘陵山区分布较广，主要栖息在林地生境，与东北刺猬（Erinaceus amurensis）同域分布，已知分布海拔最低约30 m，最高约700 m。推测在安徽南部与浙西丘陵山区一带应连续分布，但这一推测需要通过野外调查进行验证。 |
| 英文摘要: |
| Hedgehogs in the genus Mesechinus (Family Erinaceidae) include four species: M. dauuricus, M. hughi, M. wangi and M. miodon. M. wangi is only distributed in Mt Gaoligong, southwestern Yunnan, China. M. hughi is distributed in the north central part of China, and there is an isolated distribution area in the south of Anhui, China. Other two species are mainly distributed in the central and northern China (include Shaanxi, Shanxi, Inner Mongolia, et al.), and extend to Mongolia, Russia and other countries. But there is no record of the genus Mesechinus in Zhejiang, China. One specimen (Fig. 1) of Mesechinus was collected from Mogan Mountain (30°36′27″ N, 119°51′39″ E, altitude 601 m), Deqing, Zhejiang Province, China, on September 13th, 2021. Its ear is short and no longer than the surrounding spines, which is short and thin and nearly whole white. Most spines have four sections: white constituting the basal two-thirds, followed by a black ring, narrow light ring, and black tip. The skull features (Fig. 2, Table 1) are basically the same as those described by M. hughi. We sequenced the complete cytochrome b gene (Cyt b) and obtained homologous sequences of other Mesechinus species from GenBank. The p-distance of Cyt b was 0.35% between the populations in Zhejiang and Anhui, ranges from 4.92%﹣5.27% between the populations in Zhejiang and Shaanxi, and more than 7% between the populations in Zhejiang and other hedgehogs. The maximum likelihood tree based on the complete Cyt b gene showed that the specimen forms a monophyletic clade with other specimens of M. hughi (popularity rating BS = 97, Fig. 3). Based on the morphological and molecular evidences, we confirm that the specimen belongs to M. hughi, making it the first record of this species in Zhejiang, China. It is also the new distribution area found in the south of Changjiang River after the discovery of M. hughi in Anhui Province. M. hughi is widely distributed in the hilly and mountainous areas of western Zhejiang China. Its habitat is mainly woodland, and it is distributed in the same area as the E. amurensis. The known altitude range is from 30 m at the lowest to 700 m at the highest. There were accurate records in Changxing, Anji, Deqing, Yuhang, Linan, Chunan and so on in Zhejiang, China. The Huangshan Mountain area was adjacent to the hilly and mountainous areas in western Zhejiang, shares similar characteristics in terrain, landform, vegetation and so on. It is speculated that M. hughi should be widely and continuously distributed in southern Anhui and western Zhejiang, but it needs to be further investigated. |
