S. sciureus species group. Thorington (1985) and Costello et al. (1993) argued that ustus is a synonym of S. sciureus (so that the correct name should be madeirae), but this is not the case (Groves, 2001c:159). Costello et al. (1993) regarded this species as not specifically distinct from S. sciureus.
