Manaus 2003 Day 2
Posted: 29 Jun 2003, 01:18
Well, all the good stuff started today. I listened to Mike Littmann talk about <i>Leiarius</i>, and it seems that the fish commonly encountered in the aquarium trade (the spotted one with no stripes) is <i>L. longibarbis</i> (<i>L. marmoratus</i> is a junior synonym). Mike showed a pic of a freshly-caught <i>Perrunichthys</i>, and this is definitely not the fish seen in the aquarium trade. Mike also mentioned that someone went out to the market yesterday morning, and saw an 80 cm <i>L. longibabris</i> there. Rats, missed that one (I was at the market the day before)!
I also listened to Marcelo Britto talk about catfish phylogeny, with interesting results. Seems that he got a much better phylogeny than Mario did, and the results are pretty interesting. Silurids and clariids are sister groups, and <i>Horabagrus</i> is not a bagrid. Didn't take down all the details, but this is what I can remember.
I also listened to Jon Armbruster give a talk on loricariids from Guyana. There were plenty of pretty pics of undescribed loricariids, including a new <i>Hypostomus</i> that looked exactly like a brown spotted <i>Cochliodon</i> (which he considers a synonym of <i>Hypostomus</i>, only without spoon-shaped teeth, an elongate "Peckoltia</i> with a pretty barred pattern, and the new <i>Hypancistrus</i>-like thing that looks like <i>H. inspector</i> with smaller spots. Jon also said that <i>Hypancistrus</i> also consists of more than one genus and will be split.
Talked to Jon and he said that the loricariid revision (his Ph.D. dissertation) will bew published soon.
