The "Laats' Dive-in" (named after its use by Johan Laats) is often described as a variant of kata-guruma avoiding grabbing the leg. However, I have seen some debate as to how the throw should actually be classified, with some instead calling it an uki-waza variant.1
How does the Kodokan classify this throw?
Kodokan Judo Nage Waza - Various techniques and their names in its section on sutemi-waza explicitly describes a throw which starts off in a kata-guruma position but is executed by sacrificing one's balance to the ground as uki-waza:
This is a technique of following on from kata-guruma to uki-waza. In this technique, as you are sacrificing yourself and making the throw, it is not kata-guruma.
