    Schaefer (1998) provides the most recent review of the Hypoptopomatinae.

    GENERA

    Hypoptopomatini
       Acestridium
       Hypoptopoma
       Microlepidogaster
       Nannoptopoma
       Oxyropsis
       Otocinclus
    Othothyrini
       Eurycheilichthys
       Otothyris
       Parotocinclus
       Pseudotocinclus
       Schizolecis


    COMPARISONS

    Hypoptopomatines can be separated from all other loricariids based on the presence of an exposed pectoral girdle lateral to the coracoid strut.  The entire pectoral girdle may be expsoed as in the Hypoptopoma below, or just a portion as in the Parotocinclus.
