he identification of Mocholkiella paynei (Howes
1980), from Kassewe, central Sierra Leone, West Africa.
During the late 1970's early 1980's I frequently visited
the Natural History museum in South Kensington, initially
to attend an evening class in ichthyology, and then to
do some simple research into the, African catfish genus
Synodontis, of which there are many different
specimens in the fish collection.
This was a fantastic, if somewhat macabre way to spend
your spare time. Rows and rows of jars full of type specimens,
(the original fish from which a species has been described),
ranging from the Corydoras paleatus brought back
by Darwin on the Beagle, to species yet to be described.
Early summer 1980 I had seen a new catfish in some of
the shops. It looked like a Synodontis, but was
it? I brought some and had the opportunity to take a recently
dead specimen. The course at the museum had taught me
that the skeleton could help with identification. The
body was laid in some fresh water outside and nature did
its work. Within a couple of weeks the hard bony plates
of the skeleton became visible. This method, although
primitive and not exactly scientific, was effective in
this case. (I do not think you would see the skeleton
of a tetra in this way).
Looking through my reference books, this 'Synodontis'
didn't match any of those covered, so off to the museum's
collection to see if I could find it.
Gordon Howes was busy in the office, so I had free reign
to look through the collection for my fish, jar after
jar, shelf after shelf, rack after rack. No luck, time
for coffee. Gordon invited me to see what he had been
working on, a new catfish. Not a Synodontis,
but a new genus, Mocholkiella. I looked closely
at the specimens.. My Catfish! Gordon was just completing
the description. He had received three specimens from
Dr. Ian Payne in I970. After research in other collections,
to try to establish the identity of the specimens, the
description was published in 1980.
In identifying the specimens as the fish had at home,
we arranged that Gordon could come and see for himself
the living fish, and an extra bonus, the skeletal remains
I had been cleaning.
Further investigation with the retailer identified the
importer as Queensborough Fisheries at Wraysbury. A trip
to Wraysbury confirmed that the import came from Sierra
Leone, and gave Gordon more specimens to view.
As Gordon said in this article for the Catfish Association
of Great Britain, (CAGB), in July 1980, "what a strange
set of coincidences, that after having waited around in
the Museum collections for so many years, this little
catfish should have been 'discovered' by the aquarium
trade. I think this is a rather nice example of the co-operative
effort between ichthyologist and the aquarist."
