| These
two genera are keyed together because the author of these pages has only
a single female of T. tamminensis and no specimens of Putoniessiella
sagitta available. Both genera were published in the same work by Evans
(1969a)
who gave no method of distinguishing between the genera.
In his descripton of Putoniessiella, Evans states that the male genitalia have a bilobed aedeagus and sword-like pygophore process, however his illustration of P. sagitta shows no sword-like pygophore process although the aedeagus is bilobed and is drawn with what appears to be a long basal process. In contrast, no mention is made of the male genitalia in the description of Thymbrella although the illustration of T. tamminensis clearly shows a sword-shaped pygofer process. Until the holotype males of both type species are examined and some valid generic features are clearly defined, the status of both genera remains unclear. |
