THE FALCATA View in CoL -GROUP
The falcata -group includes two unpigmented species from the western Mediterranean: R. acuta ( Figs 3D View Figure 3 , 4E, F View Figure 4 ) and R. falcata ( Figs 3C View Figure 3 , 4G View Figure 4 ). These species differ from the other species of Rogneda by the fact that stylet A consists of only one plate, and by a particular construction of stylet B. According to Brunet (1979), stylet A of R. acuta can easily be derived from that of R. falcata ‘by a simple regression’ of the proximal part of the stylet. Although such a process could be imagined, it is highly speculative. Actually, stylet A of R. acuta cannot be compared with that of any of the other species of Rogneda , while stylet A of R. falcata resembles stylet B of R. reticulata ( Fig. 8E View Figure 8 ), but with the distal part of plate B1 lacking in R. falcata . Stylet B of the species of the falcata -group differs from that of all other species of Rogneda (except the species of the capulata -group) in that plate B2 is attached to the proximal end of plate B1. In R. falcata , plate B1 is sickle-shaped and plate B2 is digitiform. In R. acuta , stylet B is more of the typical form, with plate B2 being plate-shaped and distally forked.
