Treatment

Caulobothrium tetrascaphium Riser, 1955 View in CoL

( Fig. 6A, B View FIGURE 6 )

Examination of the apical region of a bothridium of C. tetrascaphium with SEM ( Fig. 6A View FIGURE 6 ), as well as frontal sections of a second bothridium ( Fig. 6B View FIGURE 6 ) (LRP No. 10256) confirms that the structure on the anterior margin of each bothridium of this species is a sucker, rather than a loculus, following the criteria of Caira et al. (1999). Most importantly, the posterior margin of this structure is rounded, rather than straight.
