I know the sith academy codex entry has been fixed as it popped for me the other day when i returned to korriban after a year with my 1st inquisitor.
Also I can confirm that you can now obtain the following species codex entries:-
Togrutu on Tython - if you were coming from the shuttle off world at the jedi temple, turn left into room with blue sphere, there is now a datapad behind a seated togruta at the back of the room.
Advozse :- On empire side kill a Fa'athra merc on Hutta, Republic on coruscant in the South eastern part of the old galactix market kill a guild muscle or guild scout.
The following 4 are on Nar Shadaa at the lower promenade(not upper promenade);
Chagrian:- close to the republic taxi there is a chagrian called 'debtor' and the datapad is next to him on a seat.
Arcona:- near a hoolographic tree is a circular seat with a group stood close by with an arconan stood with them, the datapad is on the seat.
Nikto:- datapad is near Ta'rahg the heavy armor vendor.
Neimodian:- datapad is on the counter next to Tunjas the stim vendor.
