Nantou; 3 km SW of Tsuifeng 2100m 121°10'E; 24°06'N 25.05.1997. leg. Cs. Szabóky The specimen of Glyptobasis brunnea that illustrated in STANGE & WANG H. (1998 Fig. 87w) is a female of Ascalohybris subjacens (Walker, 1853). I loaned the G brunnea specimens from the Sauter's collection preserved in DEI (Müncheberg). I found that Glyptobasis brunnea Esben-Petersen, 1913 is a junior synonym of Ascalohybris subjacens (Walker, 1853). Esben-Petersen's original description fits very well to Ascalohybris subjacens and his illustration shows this species either. The base of fore wing in genus Glyptobasis has pointed and triangular axillary lobe but this is obtuse in genus Ascalohybris. The apical brown spots are not specific features (although they are considered to be by Esben-Petersen), it is only individual variation widespread in genera Ascalohybris, Acheron, Protacheron and Maezous (ÁBRAHÁM 2008) as well. Furthermore the wing coloration depends on the age of the specimens. Older specimens have darker wings. As a result of misunderstanding, several authors (like STANGE & WANG H. 1998) identified all brown winged species of Ascalohybris subjacens (Walker, 1853) as Acheron trux or even Glyptobasis brunnea (brunnea means brown). FRASER (1922) also described a new species from Burma namely Glyptobasis brunnea Fraser, 1922. This homonymy was recognized by OSWALD and PENNY (1991) and the name was replaced by SZIRÁKI (1998) to Glyptobasis fraseri. Unfortunately, I could not check the validity of this species since its deposition is unknown. It flies from end of May till September. Distribution: Cambodia, China, Japan, South Korea, Taiwan and Vietnam (MCLACHLAN 1873, KUWAYAMA 1962, SZIRÁKI 2000, WEELE 1909).
