| Abstract | Certhia tianquanensis Li, 1995, is characterised as a distinct species and is combined withC. discolor in the superspeciesC. [discolor]. This probably relict species occupies an extremely small range, and has so far been found at only four sites in western Sichuan, China. It is characterised by a long tail (likeC. discolor), an extremely short bill (similar toC. nipalensis), the patterning on the underside, with white chin and throat and beige chest and abdomen (likeC. himalayana), a striking voice (clearly different fromC. discolor and all otherCerthia species), and a large genetic distance fromC. d. discolor in the cytochrome-b gene. Unlike its closest relativeC. discolor, C. tianquanensis belongs to the Palearctic fauna; it lives in a region of China inhabited by a number of relict species, several of which are closely related to species in the northern taiga zone.C. tianquanensis is not a close relative ofC. familiaris, although it was originally described as a subspecies of the latter and they are locally syntopic. The number of species in the genusCerthia thus rises from six to seven. — Chinese summary: www.do-g.de/journals/ Certhia tianquanensis Li, 1995, wird als eigenständige Art aufgefasst.C. tianquanensis ist offensichtlich eine reliktär verbreitete Art und nur von vier Fundorten aus der Provinz Sichuan, China, bekannt; nur zwei von diesen sind wahrscheinlich Brutorte (2700–2750 m).C. tianquanensis zeichnet sich aus durch langen Schwanz (wieC. discolor), durch extrem kurzen Schnabel (ähnlichC. nipalensis), durch das Farbmuster der Unterseite aus weißem Kinn und Kehle und beigefarbener Brust- und Bauchseite (ähnlichC. himalayana). Der Gesang weicht deutlich vonC. discolor ab, ferner von dem aller anderen ostasiatischenCerthia-Arten, insbesondere von den chinesisch-himalayanischen Subspezies derC. familiaris. ZuC. d. discolor, mit demC. tianquanensis wahrscheinlich am nächsten verwandt ist, besteht ein hoher Abstand im mitochondrialen Cytochrom-b-Gen. Beide werden in der SuperspeziesC. [discolor] zusammengefasst. Ursprünglich wartianquanensis als Subspezies vonC. familiaris beschrieben worden, abertianquanensis weicht von chinesischenfamiliaris durch zahlreiche morphologische Merkmale ab und lebt mit solchen lokal syntop.C. tianquanensis gehört zur paläarktischen Fauna; sie lebt im Nadelwald west-chinesischer Gebirge der Provinz Sichuan, in dem zahlreiche weitere endemische Singvogelarten mit kleinen Arealen vorkommen. Die Zahl derCerthia-Arten erhöht sich von sechs auf sieben. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
