Elsewhere, the species occurs in Indonesia (Sulawesi and West Papua), Papua New Guinea and the Solomon Islands. A high elevation species inhabiting clear, fast flowing, high gradient streams with boulders and gravel substrates.
Features	Dorsal fin V-VI - I,9; Anal fin I,9; Pectoral fin 14-15; Lateral scale series 30-43.
Feeding	A benthic microcarnivore.
Biology	Little is known of the biology and ecology of this species.
Etymology	The specific name is from the Latin discordis (= differ, disagree) and pinnis (= fin) in reference to the difference in the number of first dorsal-fin spines of males (6) and females (5).
