I don't really have a lot of info on "Kapou". I'm unable to find it on the map of Republic of
Central Africa, the closest is "Kabou" which is just north of Mobay and east of Bangui. But I
would definately not in anyway suggest that this is in fact the collection site. When looking
at a map of Africa, you will see many names that are only one or two characters different. Too
dangerous to speculate.
The RCA 91/* collection is listed by Roger Langton in Wild Collections of Fillifish as having
been made by Wolfgang Harz. He also calls RCA 91/1 a christyi and refers to the DKG Journal of
August 1993.
Huber in Killi-Data 1996 only lists one collection site for decorsei, that being Bessou in RCA.
None in Zaire, although there are nine sites listed for christyi and two for christyi aff. In
his general listing of species he lists Zaire and RCA for possible locations of decorsei.
When considering some morphs of christyi, margaretae(which some still consider a valid species),
and decorsei, it isn't hard to question the species designations. Just need to get someone
interested in doing some DNA work on these fish to resolve the matter.
