Hypsiscopus murphyi Bernstein, Voris, Stuart, Phimmachak, Seateun, Sivongxay, Neang, Karns, Andrews, Osterhage, Phipps & Ruane |
Remarks:
Previously regarded as the northern populations of plumbea, along with wettsteini (e.g., Murphy 2007) or as a synonym of wettsteini (e.g., David & Vogel 2024).
Revalidated as a separate species by Bernstein, Murphy, Lathrop, Nguyen, Orlov & Stuart (2024).
Specimens of plumbea from India (Nicobar Islands) and Myanmar will need to be identified pending future molecular and morphological comparisons
(Bernstein, Voris, Stuart, Phimmachak, Seateun, Sivongxay, Neang, Karns, Andrews, Osterhage, Phipps & Ruane 2022).
Distribution:
Cambodia,
Laos,
Thailand,
Vietnam.

Hypsirhina hardwickii Gray (Murphy 2007) |
Remarks:
Previously included the populations now assigned to murphyi and wettsteini.
Occurs in the Nicobar Islands (India), however, I have found no support for Murphy's (2007) claim that it is found in the Andaman Islands.
It was not included for the islands by Chandramouli (2022).
However, specimens from the Nicobar Islands and Myanmar will need to be identified pending future molecular and morphological comparisons
(Bernstein, Voris, Stuart, Phimmachak, Seateun, Sivongxay, Neang, Karns, Andrews, Osterhage, Phipps & Ruane 2022).
A single specimen is said to have come from the Moluccas, which would extend the range eastwards (Murphy 2007).
