2 From the Chair

Welcome to the first issue of 'Cat Chat' 2002. As far as the group is concerned the year is well under way. lt started of in style with an extra meeting on the 6th January, when we took full advantage of long-term member Michael Hardman who returned home from the USA for Xmas. The meeting took the form of a Mini Convention and was made into a free to all corners event, which proved to be the right decision, judging by the good attendance. The subjects of Michael's talks were, the of North America and Catfish . The talks were very well received by all and created much discussion afterwards. January 20th: This was the AGM , the one meeting excellent slides of a wide variety of and that everyone traditionally tries to avoid in case they environments, including non-catfish species that get roped into a job. The result being that the inhabit the same areas. Member Robin Warne, from attendance this year was very low, bordering on Huddersfield, gave the second talk of the day which abysmal.

His talk included a first in that the pictures were implementing new ideas and changing Rules etc. So, presented in digital format. Perhaps this is the way to those members who have had the odd moan about go in the future . After the lunch break it was to be how things have been done at meetings over the last Oliver's second talk but we decided to make a slight year - Where were you?

Both of them were place. How about putting your points of view on paper presented with superb catfish carvings produced by to the Secretary. If no one turns up at AGM's to tell us our very own expert wood sculptor Brian Walsh (a what they would like to see happen or not, as the case Sturisoma for Robin and a Pseudacanthicus for may be , then the committee will have to make all the Oliver). Oliver's second presentation was also a decisions without you. If there are those of you who change from the norm. He took four alleged fish disagree, you must speak up formally. it's your Group experts from the audience, Julian Dignall (Planet and your money, so the least you can do is make the catfish) , Andy Taylor (BAS), Pete Liptrot (Bolton effort once a year to tell us what you want, or even just Museum) and Derek Lambert (Editor of Today's offer some practical help.

Introduction This catalogue was recently also published in Datz Sonderheft Harnischwelse 2 (meaning Datz Special Issue Mailed Catfishes 2; lsbrucker, 2001 ). This is the first English version. lt includes the scientific names of all known (sub-) genera and (sub-) species of Loricariidae with their author(s) and year of publication. The currently correct names are printed in bold type. Synonyms are in italics. Reference is made also in italics either to which the various species are now assigned or to their senior synonym. In the same issue of Datz, lsbrucker, Seidel, Michels, Schraml & Werner also published diagnoses of fourteen new genera, while one old genus name was re-established: Hemiloricaria Sleeker, 1862, hitherto treated exclusively as a junior synonym of either or . One new substitute name (nomen novum) was issued. Acknowledgements Thanks to Elsbeth Zwart (Amsterdam) , to J.

This brings the total number of validly described species of Change of address Loricariidae to 692 in 108 genera, a fresh count. The total numbers mentioned in the previous list, 684 (but Vice President CSG (U K) 687 in lsbrucker, 2002} species in 107 genera, was too low, partly due to some of the omissions corrected here. Correctly counting zoological names is obviously Dr Peter Burgess often a quite complicated matter, particularly if only the 52 Victoria Road valid ones are given . Writtle Some of the forms yet considered as mere synonyms Chelmsford might prove to represent valid species as well. But especially the ongoing discovery and description of Essex CM 1 3PA new species will soon raise the number over 700. ENGLAND
