Wow, I just got this paper today (and its lit cited has a lot of papers I'd never seen before too!)-
Paolillo, A. and Linares, O. 2007. NUEVOS COCODRILOS SEBECOSUCHIA DEL CENOZOICO SURAMERICANO (MESOSUCHIA : CROCODYLIA). CONTRIBUCIONES OCASIONALES EDITADA POR EL LABORATORIO DE PALEOBIOLOGÍA, numero 3
This paper has several new names-
1. Barinasuchus arveloi as a replacement name for Sebecus cf. huilensis.
2. Langstonia as a new genus for Sebecus huilensis (Langston 1965).
3. Zulmasuchus as a new genus for Sebecus querejazus (Buffetaut and Marshall 1991). They also sink Sebecus carajazus (Gasparini et al. 1993) into Z. querejazus.
According to these authors, Sebecosuchia is divided up into:
1. Baurusuchidae (Price 1945): Cynodontosuchus, Baurusuchus, Stratiotosuchus, Pehuenchesuchus.
2. Bretesuchidae (Gasparini et al. 1993): Bretesuchus, Zulmasuchus.
3. Sebecidae (Simpson 1937): Sebecus, Ilchunaia, Langstonia, Ayllusuchus, Barinasuchus.
The paper is in Spanish, so I'm sure as I read through it, I'll be posting more comments later. = )
For now, I leave you with some of their photos of Barinasuchus ...

Oh this is so old news. ;)
But no less cool.
I was actually thinking of making Barinasuchus skull rec until I got cought up on reading about basal archosaurs and reptilian braincase anatomy. :P
that's actually pretty cool Ville, to be honest (if it wasn't clear from my post), I didn't know about this paper til today myself :-(
They are very cool looking animals though, it seems to me like sebecosuchians are basically more robust/heavier peirosaurs with taller and bigger skulls (so they look more macho all around heh).. hehe
An interesting note from that paper is that Barinasuchus appears to be the largest of the traditional sebecosuchians. The scale bar in that photo is 10 cm.!
The paper is freely available online for interested parties. Googling any of the new genera turns it up quickly.
