Taxonomic List
The list was made according to Cutler’s (1994) system. Our brief remarks are included in brackets. Registration numbers with suffixes, such as UMUTZ-Spc-2-1 and -2-2, mean that the thus numbered specimens had been kept in the same jar and divided into two (in this case) or more jars during the course of the present study, in order for the different species to be stored differently. Duplicate information in labels is not shown; the whole label information will be open by the Internet.
