I don't think anybody has mentioned this yet:

Chiappe, L. M., Suzuki, S., Dyke, G.J., Watabe, M., Tsogtbaatar & Barsbold, 
R. 2006. A new enantiornithine bird from the Late Cretaceous of the Gobi 
Desert. Journal of Systematic Palaeontology (online preprint)

We report on a new species of enantiornithine bird from the Late Cretaceous 
of the Mongolian Gobi Desert, which adds to
themeager record of birds from the latest part of the Mesozoic in this 
region. The exceptional, three-dimensional bones of the
newfossil increase the known anatomical diversity of enantiornithine birds, 
providing information about previously
unreported morphologies such as a pneumatised furcula. Several 
synapomorphies nest the new bird within an enantiornithine
clade of proficient fliers, but the anatomy and proportions of its flight 
apparatus imply significant aerodynamic restrictions.
The combination of phylogeny and our functional interpretation suggests 
that this new fossil bird is a representative of a
flightless lineage. This discovery thus provides the first evidence of a 
trend towards more limited flying capabilities
among Enantiornithes, a group of Cretaceous birds otherwise believed to be 
represented by competent fliers.

The species name isn't mentioned in the abstract: Elsornis keni.
