REMARKS — Specimens from Kenya and Cameroon have knobbed or sharp­tipped Jv5, while all the specimens from Burundi, Democratic Republic of Congo, Rwanda, Uganda and Sierra­Leone have knobbed Jv5 and all the specimens from Ghana, Nigeria and Zimbabwe have sharp­tipped Jv5. Only the peritreme of one specimen from Rwanda reaches the level of j3 as in the original description, whereas in most of the specimens examined the peritremes extend to a level between j3 and z2.
