Larval Acanthogobius ommaturus is abundant in coastal water and estuaries of ECS in Spring. We collected serial specimens of it in Apr 2017, which range from pre-flexion to flexion ( near post-flexion ).  

As mentioned in the previous post, the dash-like melanophore near the end of anal fin the is possibly a valid feature to make a distinction with Chaeturichthys stigmatias which possesses a relatively round and inapparent melanophore in this position.
