Trachischium apteii Bhosale, Gowande & Mirza |
Remarks:
Reported from China by Wang, Ren, Chen, Lyu, Guo, Jiang, Chen, Li, Guo, Wang & Che (2020), but the species has not actually been recorded from any Chinese-controlled areas.
The inclusion of apteii in the work above is based on the fact that the distribution of the species is located in the part of Arunachal Pradesh, India, which is claimed by China
and considered part of Tibet by the Chinese government (Kai Wang, pers. comm., January 6th, 2021).
Distribution:
India
(Arunachal Pradesh).

It is unclear whether the authors intentionally removed the species from the state list in the latter work.
The species is not included for the state herein, pending confirmation.

Aproaspidops antecursorum Annandale (Smith 1943) |
Remarks:
Presence in Tibet needs confirmation.
The type locality of Aproaspidops antecursorum lies in Arunachal Pradesh in an area claimed by China.
The alleged occurrence of reticulatum in Tibet (e.g., Rao 2000; Zhao & Adler 1993) seems to be based on the sole specimen collected in this locality
(Vogel, Lalremsanga & Vanlalhrima 2017).
Distribution:
