Verdigrophis Wallach, Midtgaard & Hsiao (type species: Coluber prasinus Blyth 1854) |
Contents:
3 species, of which none is endemic.
Endemism: 0%  100%
Remarks:
The species of this genus have had a turbulent taxonomic history, with prasinus previously being assigned to
Elaphe
(e.g., Schulz 1996),
Gonyosoma
(e.g., Das 1997),
Rhadinophis
(e.g., Burbrink & Lawson 2007), and
Rhynchophis
(e.g., Wallach, Williams & Boundy 2014).
V. coeruleus was first described in 2021.
Chen, McKelvy, Grismer, Matsui, Nishikawa & Burbrink (2014) synonymized prasinus with
Gonyosoma,
along with
Gonyophis,
Rhadinophis,
and
Rhynchophis.
Wallach, Midtgaard & Hsiao (2024) revalidated the latter three genera and described Verdigrophis as a new genus to accomodate coeruleus and prasinus.
This arrangement, however, was not supported by Poyarkov, Bragin, Idiiatullina, Tran, Le, David & Nguyen (2025).
Records from Hainan need taxonomic verification (Poyarkov, Bragin, Idiiatullina, Tran, Le, David & Nguyen 2025).
Distribution:
SE. Asia.
Reported from:
Bhutan,
China
(Guangxi,
Guizhou,
Hainan,
Sichuan,
Yunnan),
India
(Arunachal Pradesh,
Assam,
Manipur,
Meghalaya,
Mizoram,
Nagaland,
West Bengal),
Laos,
Malaysia
(West Malaysia),
Myanmar,
Thailand,
Vietnam.

Gonyosoma gramineum Günther (syn. Smith 1943; David, Campbell, Deuti, Hauser, Luu, Nguyen, Orlov, Pauwels, Scheinberg, Sethy, Smits, Teynié & Vogel 2022) |
Remarks:
Previously included the populations now assigned to coeruleus and iadinus.
Now restricted to Bhutan, Northeast India, and Myanmar.
Reports from the Andaman and Nicobar Islands are considered erroneous, as no voucher specimens exist (Das 1999).
Presence in Nepal needs confirmation (Kästle, Rai & Schleich 2013).
Older records from southern Laos and Central Vietnam represent iadinus (Poyarkov, Bragin, Idiiatullina, Tran, Le, David & Nguyen 2025).
Distribution:
Bhutan,
India
(Arunachal Pradesh,
Assam,
Manipur,
Meghalaya,
Mizoram,
Nagaland,
West Bengal),
Myanmar.
