Morphological and genetic data for the Iberian golden‐striped salamander, Chioglossa lusitanica, demonstrate the existence of two groups with southern and northern ranges, connected by a zone of intergradation in central Portugal. Because reproductive isolation between them is incomplete we consider the groups to be subspecies. The type locality of C. lusitanica (Buçaco near Lousã) is situated inside the mixed zone. This necessitates identification of the nominotypical subspecies. We sequenced a fragment of mitochondrial DNA from one of the species' syntypes and we determined what position over a latitudinal transect maximizes the morphological discrimination between the groups. Both approaches indicate that C. lusitanica from Buçaco represents the southern subspecies. A new subspecies of C. lusitanica is described from a northern locality (Valongo near Porto in north‐western Portugal). A lectotype is designated for Chioglossa lusitanica. 相似文献

14、 15世纪西欧国家中相对后进的西班牙和葡萄牙率先进行海外殖民扩张是内外两种因素综合作用的必然结果。收复失地运动以及国内社会经济的变迁是西、葡向外扩张的内在动因 ;14、 15世纪西欧近代性质的国际商业网络的酝酿以及西、葡在网络中所处的劣势地位是其外向扩张的外部强制力量 相似文献
