It looks it is the misprint / error form of 倄.

The evidence shows some Chinese syllables by fanqie. There are two 韻母, and the 韻母 are stable, one is 猥, the other is 倄.

More evidence will be better.

Evidence 1 strongly suggests the character ⿰犭肴 is a misprint of 倄. The character 倄 appears 49 times on the page but ⿰犭肴 only once in a place where context suggests it should be the same as the 49 倄's. This suggests evidence 1 alone is insufficient evidence and that unless more evidence is available at this time should be moved to pending or withdrawn.
