Just saw a new book advertised that may be of interest:

Qiu, R., Wang, X., and Jiang, S. 2025. Sinosauropterygid Dinosaurs from the Jehol Biota. Shanghai: Shanghai Science and Technology Press. 100 pp. ISBN 9787547873571



Can't tell if anything new is named or described in this book from the description. If you translate the description from the Chinese, it talks a lot about "Chinese ornithopods," which I assume is a peculiar translation of "bird-y theropods."

The table of contents in the first link lists each species covered in the book under its own section, and all of them seem to be described species, so I'm guessing nothing new is named, though there is one section for "Sinosauropterygidae genus indet." ("中华鸟龙科未定属").

Google Translate gives chapter 3.5 as Yingliangosaurus zhangi, which I had never heard of before. The only Google result is the rather questionable https://www.dinosaur-universe.com/dinosaur-information/fossilized-dinosaur-egg/ . Could it be Xunmenglong yinliangis, even though all the other taxa are translated perfectly? 

It's rather weird they also have a chapter on "Lingyuanosaurus", since that was described as a therizinosaur and certainly seems to be a maniraptoriform.
I'd be interested to read chapter 4.4.3 "Discussion of the validity of Compsognathidae" since i don't see how the authors can get around its priority.

Yes, 3.5 is Xunmenglong. If transliterated phonetically, 英良迅猛龙 = Yinliang xunmenglong (i.e., Xunmenglong yinliangis).

Oddly enough, on my end Google Translate does not seem to be showing the same results and is translating taxon names far from perfectly, for example giving 2.2 as Ichthyosaurus and 2.3 as "Pterosauridae".

In any case, the genera/species that have section titles are (as translated by me and not auto-translation software):

2.1.2 Compsognathus
2.1.3 Juravenator
2.2 Mirischia
2.3 Aristosuchus
2.4 Scipionyx
3.2 Sinosauropteryx prima
3.3 Huaxiagnathus orientalis
3.4 Sinocalliopteryx gigas
3.5 Xunmenglong yinliangis
3.6 Sinosauropteryx genus indet.
4.1 Sinosauropteryx lingyuanensis
4.2 Huadanosaurus sinensis

No Lingyuanosaurus, as far as I can make out.

My Google Translate gives-

"2.1.2 *Compsognathus* 
2.1.3 *Juravenator* 
2.2 *Mirischia* 
2.3 *Aristosuchus* 
2.4 *Ornitholestes*
3.2 *Sinosauropteryx prima* 
3.3 *Huaxiagnathus orientalis* 
3.4 *Sinocalliopteryx gigas* 
3.5 *Yingliangosaurus zhangi* 
3.6 Unidentified Genera of Sinosauropterygidae
4.1 *Lingyuanosaurus* 
4.2 *Sinocalliopteryx*"

But obviously your translation is correct, with chapter 4 being the last two species they described. I'm betting the book is most useful for its photos, but we'll see. I ordered it, so I'll give it a review once it arrives.

If you do a search on the Chinese characters rather than translate them, it goes to Xunmenglong yinliangis on Chinese webpages.
