Lingshui Keelback, (Adler's Keelback, Hainan Keelback)

Lingshui-Kielnatter

Lingshui-kølsnog

1997 Rhabdophis adleri Zhao

Remarks: Represents populations previously reported as callichroma or chrysargos (David & Ineich 1999). Tentatively considered an endemic to Hainan (see remarks under callichroma).
Distribution: China (Hainan).


Rhabdophis akraios

Mount Singalang Keelback

Singalang-Kielnatter

Nordvietnamesische Kielnatter

Nordvietnamesisk Kølsnog

1934 Natrix angeli Bourret
Rhabdophis angeli Bourret 1936

Distribution: Vietnam.


Rhabdophis auriculatus

White-lined Keelback, (Günther's Philippine Keelback, Günther's White-lined Water Snake)

Weissstreifen-Kielnatter

Hvidstribet Kølsnog

1858 Tropidonotus auriculatus Günther
Natrix auriculata Griffin 1911
Rhabdophis auriculata Malnate 1960
1970 Rhabdophis auriculata myersi Leviton

Remarks: Records from Luzon (e.g., Leviton 1970; Golay, Smith, Broadley, Dixon, McCarthy, Rage, Schätti & Toriba 1993; Iskandar & Colijn 2001) appear to be erroneous. The island was not included in the distribution by Diesmos, Gonzalez, Delima & Tampos (2009). Leviton, Siler, Weinell & Brown (2018) included the species in the species list for Luzon, but in the species account there was no mention of the island, and no localities were plotted in the map.
Distribution: Philippines (Bohol, Dinagat, Leyte, Mindanao, Samar, Siargao, Sulu Islands [Basilan]).


Rhabdophis barbouri

Luzon Keelback, (Barbour's Keelback)

Luzon-Kielnatter

Luzon-kølsnog

1854 Leptophis vertebralis Dumeril, Bibron & Dumeril [rejected] (Smith & Chiszar 1989)
1922 Natrix barbouri Taylor
Macropophis barbouri Malnate 1960
Natrix dendrophiops barbouri Leviton 1963
Rhabdophis barbouri Malnate & Underwood 1988

Remarks: Presence in Mindoro needs confirmation. There is a single record, which may be in error (Diesmos 2009). Leviton, Siler, Weinell & Brown (2018) did not include Mindoro in the distribution of the species.
Distribution: Philippines (Luzon).


Rhabdophis bindi

Bindi Keelback

Bindi-Kielnatter

Bindi-kølsnog

2021 Rhabdophis bindi Das, Smith, Sidik, Sarker, Boruah, Patel, Murthy & Deepak

Remarks: Previously regarded as a population of himalayanus.
Distribution: Bangladesh, India (Assam, Mizoram, Tripura).





Rhabdophis callichroma

Bavi Keelback, Black-barred Keelback, Coloured Keelback

Bavi-Kielnatter

Bavi-kølsnog

1934 Natrix chrysarga callichroma Bourret
Rhabdophis chrysargus callichromus Bourret 1936
Rhabdophis callichroma Malnate 1960
1939 Natrix auchenia Smith (Smith 1943)

Remarks: Previously regarded as a synonym of chrysargos (e.g., Zhao & Adler 1993). According to David & Ineich (1999), records from China (Hainan) refer to adleri, however, Zhu, Wang, Takeuchi & Zhao (2014) list vouchers of both adleri and callichroma from the island. Chinese records of callichroma or chrysargos from outside Hainan are here tentatively assigned to callichroma. Not listed for China by Wang, Ren, Chen, Lyu, Guo, Jiang, Chen, Li, Guo, Wang & Che (2020). Only two specimens have been reported from Hong Kong (Karsen, Lau & Bogadek 1998 [as chrysargos]). David & Ineich (1999) regarded the specific epithet as an apposition, not an adjective, thus suggesting the correct spelling to be callichroma, not callichromus.
Distribution: China (Guangdong, Hainan, Hong Kong), Vietnam.


Rhabdophis callistus

Minahassa Keelback, (Boettger's Keelback)

Minahassa-Kielnatter

Minahassa-kølsnog

1873 Tropidonotus callistus Günther
Rhabdophis callistus Iskandar & Colijn 2001

Remarks: Previously regarded as a synonym of chrysargoides (e.g., Rooij 1917). Treated as a valid species in most recent publications (e.g., Iskandar & Colijn 2001; Lang & Vogel 2005). According to Lang & Vogel (2005), the species is endemic to Sulawesi, but Iskandar & Colijn (2001) and Koch (2012) include Sangir Island in the distribution, but without reference to vouchers. Confirmation is therefore needed.
Distribution: Indonesia (Sulawesi).


Rhabdophis ceylonensis

Sri Lanka Keelback, (Sri Lankan Blossom Krait)

Srilankanische Kielnatter

Srilankansk Kølsnog

1858 Tropidonotus chrysargus ceylonensis Günther

Distribution: Sri Lanka.


Rhabdophis chiwen

Chiwen Keelback

Chiwen-kølsnog

2020 Rhabdophis chiwen Piao, Chen, Wu, Shi, Takeuchi, Jono, Fukuda, Mori, Tang, Chen & Ding

Distribution: China (Sichuan).





Rhabdophis chrysargoides

Javanese Keelback, (Sahul Keelback, Günther's Keelback)

Java-Kielnatter

Java-kølsnog

1858 Tropidonotus chrysargoides Günther
Amphiesma chrysargoides Jan 1863
Natrix chrysargoides Barbour 1912
Rhabdophis chrysargoides Malnate 1960

Remarks: Previously included callistus. According to Iskandar & Colijn (2001), chrysargoides is restricted to Java, but some authors (e.g., Lang & Vogel 2005; Koch 2012) have also included Buton, Muna, Sangir Islands and Sulawesi, but the status of these populations is uncertain. Moreover, Zhu, Wang, Takeuchi & Zhao (2014) listed a voucher from Palawan, Philippines, however, this record is regarded herein as questionable, since no other references seem to confirm the presence of chrysargoides in the Philippines. See further remarks under chrysargos.
Distribution: Indonesia (Buton, Java, Muna, Sangir Islands, Sulawesi).


Rhabdophis chrysargos

Speckled-bellied Keelback, Speckled Keelback, Spotted Keelback, (Schlegel's Keelback)

Gefleckte Kielnatter, Gefleckte Wassernatter

Spættet Kølsnog

1827 Tropidonotus chrysargus Boie (nomen nudum; David & Vogel 1996; Iskandar & Colijn 2001)
Amphiesma chrysargum Duméril & Bibron 1854
Natrix chrysarga Stejneger 1907
Rhabdophis chrysargus Wall 1923
1837 Tropidonotus chrysargos Schlegel
Amphiesma chrysargos Jan 1861
Rhabdophis chrysargos David & Vogel 1996
1858 Tropidonotus junceus Cantor (Smith 1943)
Tropidonotus chrysargus juncea Boettger 1887
1854 Leptophis albomaculatus Duméril, Bibron & Duméril (Golay & al. 1993)

Remarks: Records from China refer to adleri or callichroma (see remarks under those species). Presence in Sulawesi and nearby islands has been questioned, since only a few voucher specimens are available from the island, and since chrysargos may have been confused with chrysargoides (Lang & Vogel 2005; Koch 2012). All records of chrysargos from Sulawesi and nearby islands are here tentatively considered to represent chrysargoides, pending further studies. Specific epithet is chrysargos, not chrysargus, and the author is Schlegel 1837, not Boie 1827, as often seen (see above or David & Vogel 1996).
Distribution: Brunei, Cambodia, Indonesia (Anambas Islands, Bali, Bawean Islands, Java, Kalimantan, Nias, Penida, Siberut, Simeulue, Sipura, Sumatra), Laos, Malaysia (Sabah, Sarawak, West Malaysia [incl. Langkawi Archipelago, Seribuat Archipelago (incl. Tioman)]), Myanmar, Philippines (Balabac, Calamian Islands [Busuanga, Culion], Dumaran, Palawan), Thailand, Vietnam.

1925 Natrix helleri Schmidt
Natrix subminiata helleri Fan 1931
Rhabdophis subminiata helleri Pope 1935
Rhabdophis helleri David & Vogel 2021

Remarks: Previously regarded as a subspecies of subminiatus (e.g., Smith 1943). Revalidated as a separate species by David & Vogel (2021). A record from Shanxi (Guo, Wang & Lian 2002, as subminiatus) is regarded as doubtful.
Distribution: Bangladesh, Bhutan, China (Fujian, Guangdong, Guangxi, Guizhou, Hong Kong, Sichuan, Yunnan), India (Arunachal Pradesh, Assam, Meghalaya, Mizoram, Nagaland, Odisha, Sikkim, Tripura, West Bengal), Laos, Myanmar, Nepal, Thailand, Vietnam (incl. Cat Ba Island).

1925 Natrix speciosus Wall (Smith 1943)

Remarks: Previously included the populations now assigned to bindi. Records from Bangladesh, Mizoram, and Tripura are regarded as representing bindi. Reports from Laos (e.g., Deuve 1970; Uetz & Hallerman 2007; Teynié & David 2010) are based on the former subspecies laobaoensis, now considered a synonym of siamensis (Bain & Hurley 2011).
Distribution: Bhutan, China (Tibet, Yunnan), India (Arunachal Pradesh, Assam, Meghalaya, Nagaland, Sikkim, West Bengal), Myanmar, Nepal.

Rhabdophis nuchalis Malnate 1960
1927 ? Natrix nuchalis collaris Vogt (status unclear, according to Nguyen & David 2023)
Natrix swinhonis collaris Deuve 1970

Remarks: Previously included pentasupralabialis. Now restricted to central China (Nguyen & David 2023). Records from other countries represent other species (e.g., leonardi), or are assumed to be misidentifications (Nguyen & David 2023). Particularly, a record from Himachal Pradesh (Agrawal 1979) is regarded as erroneous, being far from the nearest other records of this or any other closely related species. Records from Nagaland, India, are tentatively referred to leonardi, following Nguyen & David (2023). Records from the Chinese provinces Guangxi and Guizhou are also assumed to represent other species (Nguyen & David 2023). Presence in Hong Kong needs confirmation, since there is only a single record (Karsen, Lau & Bogadek 1998). Lau, Guo, Zhou & Rao (2012) did not include Hong Kong in the distribution.
Distribution: China (Chongqing, Gansu, Henan, Hubei, Hunan, Shaanxi, Sichuan, Yunnan).

1899 Pseudoxenodon intermedius Lönnberg (David & Vogel 2021)
1931 Natrix subminiata hongkongensis Mell [1929] (David & Vogel 2021)

Remarks: Previously included helleri, siamensis, and the population now assigned to confusus. Presence in Sulawesi needs confirmation, since only a single voucher specimen is available from the island (De Lang & Vogel 2005). Although reported from Borneo by several authors (e.g., De Rooij 1917; Haas 1950; Haile 1959; Stuebing 1991; Iskandar & Colijn 2001; Iskandar 2004; Das 2006, 2010), it is not included for the island herein, following Stuebing, Inger & Lardner (2014) and David & Vogel (2021), who did not regard subminiatus as a Bornean species.
Distribution: Indonesia (Java, Nias, Nusa Kambangan, Sumatra).
