Dinosaur Genera List corrections #130

[Dinogeorge@aol.com]

No sooner do I put together DGL corrections #129 than a note arrives from 
Great Britain's Darren Naish about a new Brazilian dinosaur. The dinosaur is 
described in an abstract, in a volume that appears to be in a journal series. 
I have edited his account a bit. Pagination for the abstract wasn't included 
in Darren's note. Here is the citation:

Kischlat, E.-E., 1999. "A new dinosaurian ?rescued' from the Brazilian 
Triassic: Teyuwasu barbarenai, new taxon," Paleontologia em Destaque, Boletim 
Informativo da Sociedade Brasileira de Paleontologia 14(26): [April, May, 
June, 1999].

Darren writes, "In reviewing Triassic archosaurs from Rio Grande do Sul for 
phd work, Kischlat made Hoplitosuchus Huene 1942 a nomen substitutum for
Hoplitosaurus Huene 1938: I'm not quite sure why. A right femur and tibia 
previously referred to this taxon is actually from a dinosaur and recalls Mara
suchus and Herrerasaurus: is here named Teyuwasu barbarenai. Generic is from 
the tupi words te'yu (lizard - presumably the basis for the word tegu) and 
wa'su (big): thus 'big lizard'. Cool. Don't think much of the material 
though."

Accordingly, we add

Teyuwasu Kischlat, 1999

as genus #875 in the Dinosaur Genera List, and we also add the entry

Teyuwasu Kischlat, 1999
    T. barbarenai Kischlat, 1999?

to the table of South American dinosaur species. Although the description is 
in an abstract, I'm not presently listing it as a nomen nudum, as the 
description seems to be properly published. (Haven't heard of this journal 
before, however.)

As I understand it, the Hoplitosuchus problem occurred because von Huene 
misspelled the name Hoplitosaurus somewhere along the line (1938?), and this 
misspelling is preoccupied by Lucas, 1902, for an Early Cretaceous North 
American polacanthine ankylosaurian. Unfortunately, I can't check my library 
because the relevant papers are still boxed. My files have 1938 as the date 
for both of von Huene's names Hoplitosaurus and Hoplitosuchus, but it is 
still possible that von Huene used the preoccupied name Hoplitosaurus before 
he used Hoplitosuchus. If so, the latter would be a replacement name for the 
former; otherwise the former is simply a misspelling of the latter.
