Rem.: For Heron & Bradford-Grieve (1995, p.21) this species closely resembles T. conifera, but may be distinguished by a more robust overall appearance, especially the genital segment in lateral view. There are also small differences in sizes of spines on legs 2-4 those of T. quadrata being longer, especially the inner termibal spine of P2 endopod. The width of the serrate, hyaline flange on spines and the size of the conical processses of legs P2 and P3 endopods are more pronounced than those of T. conifera.
