Trochoideus masoni and T. desjardinsi are similar in body-shape and size. The male antennal club of T. desjardinsi (Fig. 1) is similar to that of T. masoni, and not useful for identifying the species. In contrast, the female antennal club of T. masoni consists of several definable segments, while the antennal club of female T. desjardinsi is unsegmented. (Skelley and Burgess, 1995)
