Die Berg-Wolfszahnnatter (Lycodon ruhstrati) ist eine Schlangenart aus der Gattung der Wolfszahnnattern (Lycodon), die hauptsächlich im Südosten Chinas und auf Taiwan verbreitet ist.
Wolfszahnnattern haben einen Oberkieferknochen, der nach innen gebogen ist. Die Schlangen der Art Lycodon ruhstrati weisen 212 bis 229 Ventralia (Bauchschuppen) auf.[1]
Die Schlangen leben in bergigen Gebieten, wo sie auf Hängen, in Höhlen und unter Steinen in Gebirgsbächen zu finden sind.[2] Nach Harrington et al. (2018) sind sie teilweise baumbewohnend.[3] Als Wolfszahnnatternart ist Lycodon ruhstrati ovipar (eierlegend).[1] Die Weibchen legen Gelege mit bis zu vier Eiern.[2]
Die Art ist hauptsächlich im Südosten Chinas und in Taiwan verbreitet. Darüber hinaus kommt sie im Norden Vietnams vor und nordöstlich Taiwans auf den japanischen Ryūkyū-Inseln. Die IUCN stuft die Art aufgrund ihres großen Verbreitungsgebiets als nicht gefährdet ein.[2]
Die Berg-Wolfszahnnatter wurde 1886 von dem deutschen Herpetologen Johann Fischer als Ophites ruhstrati erstbeschrieben. Benannt ist sie nach Ruhstrat, der Exemplare der Art in Taiwan sammelte.[1]

Es werden zwei Unterarten unterschieden:[1]
Die Unterart L. r. ruhstrati weist bei Männchen 212 bis 228 Ventralia und 217 bis 224 bei Weibchen auf. Männchen der Unterart L. r. abditus haben dagegen 214 bis 224 Ventralia und Weibchen 220 bis 229.[1] Eine weitere Unterart L. r. multifasciatus wird inzwischen als eigene Art beschrieben (Lycodon multifasciatus).[5]

Lycodon ruhstrati, also known as Ruhstrat's wolf snake,[1] the mountain wolf snake, or the Formosa wolf snake,[2] is a species of non-venomous colubrid snake found in Taiwan, southern and eastern China, and northern Vietnam.[2][1]
The specific name, ruhstrati, was chosen to honor German-born Ernst Konrad A. Ruhstrat (died 1913), of the Imperial Chinese Customs Service, who collected the type specimens of this species in southern Taiwan.[2][3]
Lycodon ruhstrati is a member of the genus Lycodon, a genus of snakes commonly known as wolf snakes.[4] The genus belongs to the snake family Colubridae. Colubridae is the largest snake family, with member genera and species being found on every continent except Antarctica.[5]
The genus Lycodon has at times been placed in the genus Oligodon, but this classification is under dispute.[1] The species Lycodon multifasciatus was previously listed as a subspecies of L. ruhstrati, being classified as Lycodon ruhstrati multifasciatus in 1984. However, in 2008 it was classified as a separate species as Lycodon multifasciatus.[2] The species Dinodon futsingensis, first described in 1928, was synonymised with Lycodon ruhstrati in 1929. However, in 2009 it was recognized as a separate species, and named Lycodon futsingensis.[6] In 2013, the genetic sequence of L. ruhsrati was used as part of a study which suggested combining the genera Lycodon and Dinodon.[6] L. ruhstrati currently has two subspecies: Lycodon ruhstrati ruhstrati (Fischer, 1886), the nominate subspecies, first described from Taiwan; and Lycodon ruhstrati abditus (G. Vogel et al., 2009), described from Vietnam.[2]
The color pattern of L. ruhstrati is highly variable, although it tends to be dark-colored with several light-colored crossbands on its back. The largest specimen found prior to 2008 had a total length (including tail) of 94 cm (37 in).[7]
L. ruhstrati is oviparous, or egg-laying, with females laying four eggs in each clutch.[1] It is a montane species and is found on slopes, in caves, and beneath stones in mountain streams. It is also found in agricultural land and both natural and plantation forests in the foothills.[1]
The snake is known to predate upon the brown anole, Anoles sagrei,[8] as well as upon Diploderma swinhonis.[9]
L. ruhstrati occurs in the Tranninh Plateau of Laos, in northern Vietnam, and a number of locations in southern China. It has been found in Hong Kong and Taiwan, as well as the Chinese provinces of Anhui, Fujian, Gansu, Guangdong, Guanxi, Guizhou, Jiangxi, Shaanxi, Sichuan, and Zhejiang.[7] The subspecies Lycodon ruhstrati multifasciatus (Maki, 1931) has also been found in Japan's Ryukyu islands; however, this subspecies was subsequently reclassified as a separate species.[7]
L. ruhstrati is classified as a species of Least Concern by the International Union for Conservation of Nature, because it is presumed to have a large population and to be distributed over a large area. It is also not thought to be declining very fast.[1] No steps are currently being taken to specifically conserve this species, although it is thought to be found in a number of protected areas.[1]

Lycodon ruhstrati est une espèce de serpent de la famille des Colubridae[1].
Il ne faut pas confondre cette espèce, décrite par Fischer en 1886, avec Lycodon ruhstrati Pope, 1935 qui est, quant à elle, synonyme de Lycodon futsingensis (Pope, 1928).
Cette espèce se rencontre[1] :
Selon Reptarium Reptile Database (17 février 2014)[2] :
Cette espèce est nommée en l'honneur d'Ernst Konrad A. Ruhstrat (-1913)[3], qui a collecté les spécimens de le Sud de Taïwan. Le nom de la sous-espèce Lycodon ruhstrati abditus vient du latin abditus, caché, en référence au fait que cette sous-espèce est longtemps restée confondue[4].
