It is separated from all other barred congeners except A. monticola by its unique coloration pattern of 8-12 vs. 5-7 vertical dark bars on the dorsum and flank. Although 8 vertical black bars are also present in specimens ofA. monticola, the new species is distinct from it by having a well-developed （vs. poor-developed） lower lip, with or without a median interruption （vs. with a median interruption which wider than 1/2 mouth width） on lower jaw, the lower jaw entirely covered （vs. uncoverd） by the lower lip, body depth 22.57%-25.22% SL （vs. 25.64%-32.26% SL）. Additional characteristices as follows： last simple dorsal-fin ray soft without serration; dark stripes on membranes between dorsal-fin rays; dark stripes absent on membranes between anal fin rays; maxillary barbels longer than eye diameter, extending to posterior edge of eyes.展开更多
