Trichopodus poptae, new species, is distinguished from all other species in the genus by an almost non-discernible colour pattern, except for a single black blotch at the base of the caudal fin; fewer lateral scales (34-38, vs. 40-65); fewer total dorsal-fin rays than T. pectoralis (14-16, vs. 17-18); more total dorsal-fin spines than T. microlepis (6-7, vs. 3-4); fewer total anal-fin rays than T. microlepis and T. pectoralis (38-41, vs. 44-50). An artificial key to the genus is provided.
