A study by Allen W.L. Lo and Stanley K.H. Shea published recently in Marine Biodiversity Records, has found 4 species of reef fish not previously known from Hong Kong waters. They also conclude that these 4 species are not introduced. So here is a welcome list of Hong Kong’s newest residents:
Ambyleleottis japonica
A Goby that grows to only 8.5 cm length and lives near the bottom and about which very little is known.

The authors of the paper did not identify it to species so this is just a placeholder.
