Diagnosis.- The genera and species of the subfamily Astrodoradinae can be distinguished by the following combination of characters: spinous postcleithral process (except in Anadoras ^ZBK); lacrimal serated (except in Anadoras ^ZBK), forming anterior corner of orbit (except in Physopyxis; also present in Pterodoras ^ZBK and Lithodoras ^ZBK); number of pleural ribs reduced, four to seven (also shared with Acanthodoras ^ZBK, Agamyxis ^ZBK, Trachydoras ^ZBK, Doras fimbriatus ^ZBK, D. punctatus ^ZBK and Oxydoras eigenmanni ^ZBK).
