I've been reading some of the new papers (I don't have them all yet), in

excludes ornithomimosaurs and maniraptorans since they are closer taxa to
the tyrannosaurids than Allosaurus
Ahhh... but are they? I recall seeing at least one fairly recent phylogeny
that found tyrannosaurs to be the next outgroup above carnosaurs. Perhaps
it was an AMNH paper.

Yep. Pretty straight forward descriptive anatomical stuff: it was the
paper in which the forelimb elements of _Alectrosaurus_ were shown to be
from a segnosaur (therzinosauroid), rather than from _Alectrosaurus_
itself. (Once upon a time, _Alectrosaurus_ was famous for being a
rather large arms...).
Hence, some older publications suggested that _Alectrosaurus_ might be
closely related to the bona fide big-armed theropod _Chilantaisaurus_.
Also, _Elaphrosaurus bambergi_ is from Tendaguru as well.
