Re: Kathetys, elberti and exiguums.
Please read Huber's revision of Aphyosemion bualanum/elberti, in Huber, J.H.
1998. Miscellaneous notes on some systematic difficulties regarding old world
cyprinodonts, JAKA 31 (1) : 3-17.
When Seegers in 1988 erected elberti as a separate species (different from
bualanum), he did it because he thought that the morphology of the type of
bualanum was different from what should be expected from a member of the
Huber has re-examined the type, and partly based on the internal morphology
(x-rays), he found that the types of elberti and bualanum most probably are
the same. The differences that Seegers found, seem to be caused by the bad
state of the bualanum type (missing fin rays, compressed body etc.)
So Huber reerected the bualanum name, with elberti as a synonym.
This is still the status in his Killidata 2000.
Since this is the latest scientific revision, it's the bualanum name that
currently are valid.
If somebody has a different opinion - they "only" have to make a new
Hope it has been of help
