Proposed splits for which (full) information is currently lacking to me

At present, these are 194 taxa of which I have heard that they have been or will be proposed to be split, yet either (1) enough details are lacking to include them in the main lists, or (2) I consider the currently available information to me just too little to do so.  I cannot guarantee the correctness of the information below.  The list is here included as an appetizer and also as a request for further information.  It does include a number of taxa that have been split in some field guide for a region, but for which I have no other reference.  Species with a trailing '@' character behind their vernacular name are considered extinct.
