Estimated marginal means (± se) of the base width (BW), based on GLM models according to R. decollata collected by Prevot included in the MOTUs A and Eb (Prevot et al. 2015) and our measurements of groups L1 and L2. The horizontal dotted lines correspond to the mean BW values from the diagnoses of R. decollata (Linnaeus 1758) and R. paivae (Lowe 1861).
