Lycodon rufozonatus is a species of snake in the family Colubridae. The species is native to East Asia. It is medium-sized, nocturnal, and is considered non-venomous. Two subspecies are recognised, one of which, L. r. walli, is restricted to the Ryukyu Archipelago.

Contents

Etymology

The subspecific name, walli, is in honor of British herpetologist Frank Wall. [3]

Description

Lycodon rufozonatus typically grows to a total length (including tail) of around 70 centimetres (28 in), reaching up to 130 cm (51 in) in extreme cases. [4] The head is long and relatively flat, and somewhat separate from the neck. The medium-sized eyes bulge slightly and have vertical pupils. The ventral scales have a strong keel, while the dorsal scales are only faintly keeled; the scale count is typically 17:17:15, but can be up to 21:19:17. [4]

Geographic range

Lycodon rufozonatus is found across a large part of East Asia, from the Korean Peninsula in the north (and extending just into easternmost Russia) to northern Laos and Vietnam in the south; the bulk of its range in found in eastern China. [4] The continental populations are all placed in the nominate subspecies (L. r. rufozonatus); a second subspecies, L. r. walli, is found in the Ryukyu Archipelago of southern Japan. [5]

Behaviour and ecology

Lycodon rufozonatus lives in a wide variety of habitats; it can be found from near sea level to as high as 2,000 metres (6,600 ft), and is most common near river plains. [4] It is usually found on the ground, but is occasionally seen swimming in streams. [4] It is nocturnal, feeding on fish, frogs, lizards, snakes and young birds. [4] D. rufozonatus has a generally mild disposition, curling into a spherical mass with the head hidden when approached. Individuals can, however, be unpredictable, and some will bite readily. [4] There are very few clinical reports on the toxinology of D. rufozonatus bites, but the species appears to be non-venomous. [4] L. rufozonatus can harbour tapeworms of the genus Spirometra , and the consumption of raw meat from D. rufozonatus has led to cases of human sparganosis in Korea and Japan. [6]

Reproduction

L. rufozonatus is oviparous. [2]

Taxonomic history

The species was first described as "Lycodon rufo-zonatus " by Theodore Edward Cantor in an 1842 paper on the fauna of "Chusan" (Zhoushan, China) in the Annals and Magazine of Natural History . [7] Cantor included it among the "innocuous" (not venomous) species, and described it as "Brown, with numerous transversal crimson bands; the abdominal surface pearl-coloured, spotted with black on the tail". [7]

Common names

L. rufozonatus is known by several common names, including "Asian king snake", [8] "banded red snake", "red banded krait", "red banded odd-toothed snake" and "red-banded snake". [4]

<span class="mw-page-title-main">Milk snake</span> Species of snake

The milk snake or milksnake, is a species of kingsnake; 24 subspecies are currently recognized. Lampropeltis elapsoides, the scarlet kingsnake, was formerly classified as a 25th subspecies, but is now recognized as a distinct species. The subspecies have strikingly different appearances, and many of them have their own common names. Some authorities suggest that this species could be split into several separate species. They are not venomous to humans.

<i>Bungarus</i> Genus of venomous snakes

Bungarus is a genus of elapids native to Asia. Often found on the floor of tropical forests in South Asia, Southeast Asia and Southern China, they are medium-sized, highly venomous snakes with a length typically not exceeding 2 metres. These are nocturnal ophiophagious predators which prey primarily on other snakes at night, occasionally taking lizards, amphibians and rodents. Most species are with banded patterns acting as a warning sign to their predators. Despite being considered as generally docile and timid, kraits are capable of delivering highly potent neurotoxic venom which is medically significant with potential lethality to humans. The genus currently holds 16 species and 5 subspecies.

<span class="mw-page-title-main">Keeled scales</span> Reptile scales with ridges

Keeled scales refer to reptile scales that, rather than being smooth, have a ridge down the center that may or may not extend to the tip of the scale, making them rough to the touch. According to Street's (1979) description of European lizards and snakes, in those that have keeled scales the keels are usually stronger in male specimens and are consistently arranged according to the species of reptiles, even though many others do not have them. With European lizards, the dorsal scales are usually well keeled, while those on the flanks are more weakly keeled and those on the belly smooth. Non-European lizards such as Sphaerodactylus macrolepis also display keeled scales.

Theodore Edward Cantor (1809–1860) was a Danish physician, zoologist and botanist. He described several new species of reptiles and amphibians, and six species have been named in his honor.

Pseudocerastes is a genus of vipers endemic to the Middle East and Asia. It was originally created as a monotypic genus in 1896 by Boulenger for the species Pseudocerastes persicus, but three species are now recognised: the spider-tailed horned viper ; Persian horned viper and Field's horned viper.

No subspecies are currently recognized.

<i>Lycodon</i> Genus of snakes

Lycodon is a genus of colubrid snakes, commonly known as wolf snakes. The Neo-Latin name Lycodon is derived from the Greek words λύκος (lykos) meaning wolf and οδόν (odon) meaning tooth, and refers to the fang-like anterior maxillary and mandibular teeth. They are nonvenomous, but many members of this genus strongly resemble the venomous kraits in appearance, an example of Emsleyan mimicry.
