TL: China : Mountains west of Beijing . Distribution. China . Record of this species from Romania ( Obraztsov 1964: 151 ; Razowski 1996: 146, 1999: 44, 2003: 61) is based on incorrect interpretation of type locality of S. tscheliana . The species was described from single male collected in “Mountains west of Beijing” ( Caradja 1928: 361 , 388, 392), but not from Romania (see also Lepiforum 2022 ). Caradja (1928: 392) indicated affinity of S. tscheliana to Th. anatoliana and Th. placidana . Obraztsov (1964: 151) transferred S. tscheliana in “species incertae sedis” within Thiodia but gave no details supporting this decision. The systematic position of the species is uncertain until type remains unexamined.
