Until recently considered conspecific with G. bengalensis but suggested to be a separate species on basis of multiple characters including genetics#R; this provisionally accepted here but no characters strong, involving less obvious white supercilium (1); broader, more ochreish streaking on crown and upperparts (1); narrower pale tips to rectrices (1); deeper bill (effect size 2.3 for sexes combined, on published data#R, score 2); and (based on very few recordings; acceptance of evidence precautionary, and wider sampling may reveal greater overlap) less hesitant song, with less inflected final notes (1) and higher minimum frequency (1); plus possible absence of song-flight (never yet observed#R, but more study needed to confirm this; ns). Race sinicus, accepted in HBW, here treated as synonym of striatus#R. Monotypic.
Very localized in CE Myanmar (L Inle) and CW Cambodia (near Bakan in Pursat Province)#R. Also NE Vietnam (E Tonkin) and SE China (regularly only in Hong Kong, but recorded also in adjacent Guangdong, N Guangxi and S Guizhou). Formerly SE Myanmar (Tenasserim) and C Thailand.
