Robbea judithae

Robbea judithae , R. lotti and R. weberae

The posterior bulbus is the smallest in R. judithae , slightly larger in R. weberae and largest in R. lotti . It is wider than long in both R. judithae and R. weberae and nearly spherical in R. lotti ( Table 1). The subventral portion is slightly more prominently developed in the latter species ( Figs. 1d View Fig , 9a View Fig and 13c View Fig ). Myofilaments are limited to the anterior and posterior part in R. judithae and R. weberae ( Figs. 1e, f View Fig and 13b, d View Fig ) and evenly distributed in R. lotti ( Figs. 1d View Fig and 13c View Fig ).
