Mulyadi (2004, p.166) points ro considerable confusion has occurred in this species in the past because of the variability in the nature of the comb of denticles on inner margin of female left P5, and the lateral setae of caudal rami. In Brady's (1883) figures the denticles terminated in long ''whips'' and the outer seta on the caudal ramus was long, reaching distal end of caudal ramus, in contrast to that of T. denticulatus. A. Scott (1909) first suggested synonymy of T. denticulaus and T. barbatus when he found intermediate forms in ''Siboga'' specimens, however Sewell (1912) in examining specimens from Bay of Bengal still considered that this distinct species, suggesting that Scott has mistaken T. denticulatus for T. barbatus. Früchtl (1924) analysed a large number of individuals and fully supported Scott's case for synonymy. This was accepted by Steuer (1926), and subsequently by Sewell (1932) recognizing that the denticles could vary from obtuse to elongate and whip-like, and a long seta may or may not be present on the midlateral margin of the right caudal ramus.. In both these respects the Moreton Bay material (Greenwood, 1978) is very uniform and agrees with the previous denticulatus end of the spectrum. All specimens examined had 5 distinct obtuse denticles no evidence of whip-like extensions, there were no setae arising from the lateral margin of right caudal ramus.
