This genus is clearly authored chiefly by Sawyer, and the work in which it will be found is that of Sawyers'. It is thus essential for traceability that Sawyer be included in the authority. There is no such work as "Oosthuizen, 1986". The genus was included as new by Sawyer with the explanation ""Dr J. H. Oosthuizen proposes herein the following new genus". Sawyer then gives the authority as "Batracobdelloides Oosthuizen, 1984, with a date (and authorship) that is thus incorrect.
