These two collections are, unfortunately, unicates; they have been compared with the type of this species and, although there are a few minor differences, they do not appear to be significantly different. There is a great altitudinal disjunction between the original material from Kavanayen in the Gran Sabana and these collections on the opposite side of Venezuela, but in other respects the ecological conditions are much the same.
