(trick I9l>5; Timnw 2001. In Press) Only three .ind GcJth* /V,V/ AT. with details available in thai
six species respectively (lolal seven) have been publication. The additional material is lisled under

Possibly Ihe reason lor this lack of diversity is the previously nieulioucd in (ieddes (19X1) h\k\ vt'i\\c
paucity ol collections(7and 35 respectively)andihe new material are shown in TKi I. Synonymies
limited coverage ofbolh regions, Over the lasl 20 include main entries only, full synonymies are uiven
years many more collections have become available in CieddcsllWlh
