Stiphodon carisa, n. sp., is described based on material collected in the southernmost watershed in Lampung Province, Sumatra, Indonesia. Stiphodon carisa, n. sp., differs from all other congeners by a combination of characteristics that include having 9 second-dorsal fin rays; 15 pectoral-fin rays; 41-59 premaxillary teeth; predorsal scales sexually dimorphic in number, male with 5-11 and female with 8-16; 25-35 lateral scales; slightly embedded cycloid scales present on belly; male with a triangular-shaped first-dorsal fin with third and/or fourth spines longest but not filamentous and a patch of white fatty tissue posterior to pectoral-fin base; female usually with 5 (4-5) dusky to blackish blotches or spots along lateral midline from second-dorsal fin with usually 4 (3-4) posterior-most spots positioned close together on caudal peduncle, dusky band extending from anterior to eye to upper hypural base usually indistinct posterior to pectoral-fin base, with or without a dusky or black gular blotch; in some females xanthism exists which fades in preservation and in life yellow with orange to bright red markings. Stiphodon semoni is a species common in hill streams of eastern Indonesia and Papua New Guinea and is reported here for the first time from streams entering the Indian Ocean in Lampung Province, Sumatra, Indonesia.
