Media notes
Character 6. A1 (crown): posterolingual cusplet: absent (0); present (1).
Remarks: Unordered. In most extant genera, including outgroup and ingroup species (except M. okuensis and S. johnstoni) a posterolingual cusplet of A1 is absent (Character 6: A,B). Dannelid (1998) discussed the posterolingual cusplet in soricid genera and interpreted it as a crown sturcture that produced by 'the posterior part of the lingual cingulum' (ibid.: 162). The author mentions a 'longitudinal blade' in Myosorex that formed by anterioposterior expanding of the cusplet. This cusplet of A1 with anterior blade-like expanding in M. okuensis we score as a well-developed posterolingual cusplet (Character 6: C); relatively weak developed cusplet in S. johnstoni we score as a weak cusplet (Character 6: D). For details see S8.
