Oligodon huahin, the Hua Hin kukri snake, is a species of kukri snakes in the genus Oligodon (Fitzinger, 1826). [3] The species was first discovered and described in late 2016, and the article was published July 13, 2017. It is only known from its type locality but its range is likely to be more extensive. O. huahin is thought to be very secretive, similar to other species of the genus Oligodon. This theory is supported by the type specimen, which all were males, suggesting that it was found during the mating season where males are out and actively search for females to reproduce. This may also explain why this species had not yet been discovered [2]
Oligodon huahin is a member of the genus Oligodon, a genus common throughout central and tropical Asia. It belongs to the snake family Colubridae, the largest snake family, with member species to be found on every continent, except Antarctica. [4]
The specific epithet is an invariable noun in honor of the administrative district where the type locality lies and of its charming main city Hua Hin. O. huahin is the first species of snake endemic to Hua Hin District, Prachuap Khiri Khan Province, Thailand. The following common names are suggested "Hua Hin Kukri Snake" (English), "Ngu Ngod Hua Hin" «งูงอดหัวหิน» or "Ngu Peekeaw Hua Hin" «งูปี่แก้วหัวหิน» (Thai), "Oligodon de Hua Hin" (French), "Hua Hin Kukrinatter" (German) and Hua Hin kukrislange" (Norwegian)
The habitat, behaviour and ecology of this species is poorly known. All type specimens used for the species description were found in a moist mixed bamboo forest area with a forest stream. This type of habitat is excellent for a broad range of species with a rich species diversity of both amphibians and reptiles. Based on data for other members of the genus Oligodon, O. huahin is thought to be an oviparous (egg-laying) species, as it is not observed any Viviparity (giving live birth) among any species within this genus. This species nocturnal. Other species observed in the syntopy are as follows:
It is characterized by a maximal known SVL of 485.8 mm; 6 maxillary teeth, the posterior two enlarged; 17-17-15 or 17-15-15 dorsal scale rows; 166–173 ventral scales [6] and 35–41 subcaudal scales in males; a single anal scale; [7] deeply forked hemipenes [8] lacking spines and papillae, extending in situ to the 14th subcaudal; [9] faint [10] to nearly indistinct [11] vertebral, paravertebral and lateral stripes; no dorsal or supracaudal blotches or crossbars; [10] [11] and a uniformly ivory venter lacking subrectangular or squarish blotches. [12]
Oligodon huahin is only known from seven type specimens found at the type locality, within a range of approximately 1000m2, and therefore its distribution is poorly understood, although a "DOR" (dead on road) specimen was later found at a different location and habitat about 12 km away, which indicates that the species is adaptable to several different habitats than the one found at the type locality. This large specimen, with SVL of 520mm, was not used in the description. The holotype and the paratypes was all collected from the type locality in Hua Hin District, Prachuap Khiri Khan Province, Thailand. This species is for now proven to be endemic to the Hua Hin District, but it is likely to found in parts of the Phetchaburi Province as well.
The conservation threats to O. huahin are not known, because the species is only known from a few specimen found at the same spot. The area from which these were collected is not under any sort of protection, and is therefore threatened by deforestation. The species is «Not Evaluated» by the "International Union for Conservation of Nature" (IUCN Red List).
Cyrtodactylus is a diverse genus of Asian geckos, commonly known as bent-toed geckos, bow-fingered geckos, and forest geckos. The genus has about 300 described species as of 2020, which makes it the largest of all gecko genera.
Boiga is a large genus of rear-fanged, mildly venomous snakes, known commonly as cat-eyed snakes or simply cat snakes, in the family Colubridae. Species of the genus Boiga are native to southeast Asia, India, and Australia, but due to their extremely hardy nature and adaptability, have spread to many other suitable habitats around the world. There are 38 recognized species in the genus. According to the study done by Jiří Smíd regarding Old World cat snakes, the ancestor of the cat snake originated in Africa, from where it diversified and expanded to other countries. Despite this diversity however, the different species have very similar needs in terms of temperature and precipitation.
Oligodon is genus of colubrid snakes that was first described by Austrian zoologist Leopold Fitzinger in 1826. This genus is widespread throughout central and tropical Asia. The snakes of this genus are commonly known as kukri snakes.
Lycodon aulicus, commonly known as the Indian wolf snake or common wolf snake, is a species of nonvenomous snake found in South Asia and Southeast Asia. Early naturalists have suggested its resemblance to the venomous common krait as an instance of Batesian mimicry.
The streaked kukri snake is a species of nonvenomous snake found in Asia. It is also known as the variegated kukri or the Russell's kukri. The IUCN lists the species as least concern.
Oligodon cinereus, the ashy kukri snake or Günther's kukri snake, is a species of snake in the family Colubridae.
Oligodon theobaldi, commonly known as the Mandalay kukri snake or Theobald's kukri snake, is a species of snake in the family Colubridae. The species is endemic to Asia.
The Malayan forest gecko or banded bent-toed gecko is a species of gecko found in Southeast Asia.
The Colubrinae are a subfamily of the family Colubridae of snakes. It includes numerous genera, and although taxonomic sources often disagree on the exact number, The Reptile Database lists 717 species in 92 genera as of September 2019. It is the second largest subfamily of colubrids, after Dipsadinae. Many of the most commonly known snakes are members of this subfamily, including rat snakes, king snakes, milk snakes, vine snakes, and indigo 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 Batesian mimicry.
Oligodon kheriensis, also known as the coral red kukri snake, is a Kukri snake that was first described in 1936 from the North Kheri Division in Uttar Pradesh, India.
Lycodon cavernicolus, also known as Gua Wang Burma wolf snake, is a species of colubrid snake found in peninsular Malaysia. It was first described in 2014.
Oligodon deuvei is a species of snake in the family Colubridae. The species is endemic to Southeast Asia.
Oligodon pseudotaeniatus, commonly known as the false striped kukri snake, is a species of colubrid snake. It is endemic to Thailand and known from the Nakhon Ratchasima Province, Saraburi Province, and Bangkok. The type series was collected by Malcolm Arthur Smith. The specific name pseudotaeniatus refers to its similarity to Oligodon taeniatus, with whom it was confused prior to its species description in 2008.
Oligodon annamensis, commonly known as the Annam kukri snake or Leviton’s kukri snake, is a species of colubrid snake originally known from two specimens from Vietnam, where it was thought to be endemic. It has also since been found in Cambodia and Thailand.
Oligodon annulifer, also known as the ringed kukri snake, is a colubrid snake endemic to the island of Borneo.
Oligodon churahensis, the Churah Valley kukri snake, is a species of snake in the family Colubridae. It was discovered when a photo of it was posted in Instagram and noticed by two biologists, leading to them contacting the poster and collecting specimens of the species. It is known only from the state of Himachal Pradesh in India. The common and specific name both refer to the Churah Valley, where it was discovered.
