In India , it has so far only been reported from the Uttar Pradesh state ( BATELKA 2004 ) and in China it is only known from the eastern Kwangtung province ( GRESSITT 1941 ). It is recorded here from West Bengal (Darjeeling) and Karnataka (both India ), Gansu and Hainan Island (both China ) and Nepal for the first time.
